Gli interventi del 22 febbraio 2010 per l’emergenza sversamenti di gasolio nel Fiume Lambro e successivamente le catastrofiche conseguenze nel Golfo del Messico dell’esplosione del 20 aprile 2010 della piattaforma “Deep Horizon” hanno evidenziato come maggiore criticità la capacità di intercettazione e raccolta degli idrocarburi galleggianti.
La successiva analisi dei dispositivi offerti dal mercato dell’Oil Spill Response ha confermato detta criticità.
FLOC – FLexible Oil Collector – è la risposta di The Jonathan Project.
Dalla invenzione di FLOC discendono i prodotti innovativi, nel presente e nel futuro, di TJP, definiti dopo tutte le analisi, informazioni, valutazioni e conclusioni che qui, per punti essenziali, riassumiamo.

 

esiste il problema della normale manutenzione e pulizia di specchi acquei ristretti;
esiste una domanda di dispositivi adatti allo scopo;
c'è una offerta inrisposta alle necessità del mercato;
gli interventi per emergenze da gravi sversamenti sono discontinui e non preventivabili;
pulizia e manutenzione sono operazioni continue e pianificabili;
molto raramente lo spessore degli inquinanti da recuperare supera il millimetro di spessore;
1 mm di spessore equivale a 1 m³ per 1,000 m², circa 1 l/m²;
i riflessi argentei hanno uno spessore di circa 0.0001 mm, equivalent to 1 liter/10,000 m²;
pulizia e manutenzione sono particolarmente desiderabili in aree circoscritte e sotto-costa come darsene, porti turistici, moli, lungo mare e lungo lago ecc..
l'attuale offerta eccede la potenza necessaria e manca di efficacia; servono gru, mezzi di supporto, navi appoggio ecc.;
l'offerta non è sostanzialmente adatta a dare risposta alle necessità di pulizia e manutenzione in aree ristrette e in presenza di sottilissimi spessori di inquinanti da rimuovere.

 

Confronto ipotetico tra TJP e la concorrenza.
TJP colloca la sua offerta iniziale nell'area di mercato della prevenzione e manutenzione in luoghi ristretti e in presenza di quantità minime da rimuovere, dove la concorrenza è costosa, poco efficiente e poco versatile.
TJP individua un mercato in cui essere unica e senza concorrenti.
Nessuno offre ad un area industriale assoggettata a rischio un dispositivo semovente automatico e robotizzato in grado di muoversi da solo in un’area stabilita, di rilevare e trasmettere minacce e/o allarmi e di autocertificare il proprio risultato. Questo è quello che “fa” JP OilPatrol.
Nessuno offre un dispositivo semovente che, filoguidato o pilotato, possa strisciare lungo i moli, muoversi in una darsena e passare sotto i pontili. Questo è quello che “fa” JP OilKiller.
Nessuno offre uno skimmer per intercettare e raccogliere film sottilissimi di oli leggeri. Questo è quello che “fa” FLOC.
Nessuno offre serbatoi-filtro che, avendo trattenuto, stivandoli, i film di inquinanti raccolti, possano essere direttamente conferiti in discarica senza necessità di alcun ciclo di lavoro “sporco”. Questo è quello che “fa” DracOil.
Il mercato non offre dispositivi nautici per pulizia e manutenzione mentre offre costosi e “difficili” strumenti per emergenze gravi, dove invece TJP propone strumenti efficienti, efficaci ed economici nel rapporto costi/benefici.
La strategia di TJP prevede una prima linea di prodotti per manutenzione e pulizia di specchi acquei e successivamente una linea di prodotti per interventi d’emergenza in teatri disastrosi.
Il confronto che proponiamo tra le operatività di dispositivi di TJP e dispositivi attualmente sul mercato è progettuale.
Prendiamo in esame due scenari: il primo relativo a minime presenze di idrocarburi con riflessi argentei-arcobaleno in porti, darsene, lungo moli e banchine; il secondo relativo a sversamenti significativi per eventi accidentali. Non considerano disperdenti e solventi che non prelevano l’inquinante ma lo affondano o lo sciolgono nell’acqua mentre il nostro obiettivo è di rimuovere l’inquinante asportandolo dalla massa d’acqua
1) iridescenze nel Porto di Trieste
2) chiazza arcobaleno
3) iridescenze sul fiume Mississipi
4) posa di tovaglie assorbenti
5) skimmer a spazzole oleofile
6) panne intrise da smaltire
Nelle figg. 1, 2, e 3 inquinamenti che verrebbero oggi trattati con tovaglie o panne assorbenti che devono essere trasportate e disposte sulla superficie d’acqua a mezzo di barche, devono avere il tempo di assorbire l’inquinante e devono successivamente essere rimosse, sempre con l’utilizzo di barche, imballate e conferite ad una discarica. Altra possibilità è quella di utilizzare skimmer (a spazzole quello di fig. 5) ma, come si nota dall’immagine, è necessario che la pellicola di inquinante sia veramente spessa perché si possa avere un risultato apprezzabile. TJP ha progettato Oil Killer proprio per dare risposta a questi tipi di intervento (fig. A e C)
7) petrolio in mare a Taranto
8) sversamento in Giappone
9) scie di petrolio
10) intervento della Guardia Costiera
11) gestione di uno skimmer a dischi
12) gestione di uno skimmer a rulli
Sversamenti del tipo di quelli nelle figg. 7, 8 e 9 richiedono interventi “potenti” dato che la quantità di greggio sversato e da recuperare è nell’odine dei quintali se non delle tonnellate. L’utilizzabilità della maggior parte dei dispositivi oggi in commercio richiede tempi d’intervento quasi immediati, prima che il petrolio si disperda, in poche ore, in una sottile pellicola.
Gli interventi nelle immagini 10, 11 e 12 sono eseguiti secondo gli standard attuali; si può rilevare la difficoltà di gestione di skimmer a rulli o dischi, calati in acqua con funi o gru e poi governati con spostamenti continui nella chiazza da asportare. L’immagine 10 mette in evidenza tutta la difficoltà di riuscire a raccogliere macchie frastagliate di petrolio con uno skimmer a dischi.
TJP ha progettato dispositivi adatti a rispondere a questo tipo di emergenze con efficienza ed efficacia.
TJP Oil Killer raccoglie fino a 0,5 m³ di petrolio prima della sostituzione di DracOil. La sua velocità operativa è compresa tra 2 e 3 knots e naviga autonomamente, pilotato nella direzione delle scie o delle chiazze da raccogliere. TJP BOS con tubo adduttore moltiplica la capacità estrattiva, necessita di una imbarcazione d’appoggio da bordo della quale è filoguidato e mantiene inalterata la capacità di catturare scie e chiazze di greggio.

JP | Tuesday, 28th April 2015

The emergency response for the diesel oil spill in the river “Lambro” in 2010, February the 22nd and subsequently to the catastrophic consequences of the “Deep Horizon” explosion in 2010, April the 20th in the Gulf of Mexico have shown that the most critical point in oil spill response is the capability to intercept and collect the water surface and the pollutant over it floating.
The request of ships and devices which are able for remove oil and polluting spills from the sea is more and more increasing in the recent years. These systems may remain unused for years and, at same time, need frequent and very expensive maintenance.
Their availability requires a transferring to the incident place which can be made also after many hours or days after the oil spilling.
The new idea is to design a light and flexible system which can be docked directly on the ships or in small boats which can lay down and contain the oil slick.
By so doing the pollution control could be more effective and the environmental damage could be better controlled in very short time.
It consist in a floating funnel-shaped collector having an I/O balanced flow which conveys the free surface of the mixture of water and hydrocarbons for the separation and then collects the pollution in tanks. By so doing the percentage of hydrocarbons recovery is higher in comparison with the traditional oil skimmers.
The availability of a such system, which could be used as a standard equipment, could allow fast and timely rescue.
A small layout of the device can be used for cleaning maintenance of stretches of water in ports and docks.
The subsequent analysis of the Oil Spill Response offered devices confirmed the critical point.
FLOC – FLexible Oil Collector – is the TJP answer to that need.
All the TJP innovative devices, in the present and in the future designs, are descending from analysis, valuations, marketing, research and development that here we resume:

 

  1. it exists the problem of normal cleaning up, maintenance and protection of water areas;
  2. there is a demand for tools suitable for such purposes;
  3. there is an offer in response to the needs expressed by the demand;
  4. emergency oil spill responses are discontinuous and not programmable;
  5. prevention and maintenance are continuous and programmable;
  6. the oil to be reclaimed very rarely exceeds 1 mm thick;
  7. 1 mm thickness corresponds to 1 m³ per 1,000 m², about 1 l/m²;
  8. the silver reflection has a thickness of 0.0001 mm, equivalent to 1 liter/10,000 m²;
  9. prevention and maintenance take especially place in confined areas and under-coast (harbors, docks, piers, etc.).
  10. the offer has power excess and lacking versatility; cranes, supporting means, boats and ships are needed;
  11. the offer is substantially not suitable to effective prevention operations, maintenance in confined areas and in the presence of small quantities to be removed.

The TJP identifies a market where being unique and unrivaled.
None provides to an industrial area subjected to risk a self-propelled automatic and robotic device capable of moving by itself in a determined area, to detect and transmit threats and/or alarms and to self-certify its result. This is what TJP OilPatrol “does”.
None offers a self-propelled device, wire-guided or controlled, able to follow along the piers, move into a port and go under the piers. This is what TJP OilKiller “does”.
None offers a skimmer to intercept and collect thin film of light oil. This is what FLOC “does”.
None offers filter-bags that, having stored the collected pollutants, can be directly sent to landfill without the need of any cycle of “dirty” work. This is what DracOil “does”.
The market doesn’t offer devices for water cleaning and maintenance while gives offers for expensive and “difficult” tools suitable for major emergencies. Instead TJP proposes tools that are efficient, effective and economical in cost/benefit ratio.
The TJP strategy provides a first line of products for cleaning and maintenance of stretches of water and then a line of products for emergency response in disastrous theaters.
The comparison between the operation of TJP devices and the devices currently on the market is descending from the design.
Consider two scenarios: the first with minimum hydrocarbons presence, with silver-rainbow reflections, in ports, docks and piers; the second related to significant spills for accidental events. We don’t consider dispersants and solvents because they don’t remove the pollutants but they sink or dissolve it into the water mass while our goal is to remove the pollutant picking it up from the body of water.

Figs. 1, 2, and 3 represent pollution that today would be treated with absorbent cloths or booms that must be transported and layed down on the surface of water by means of boats, must have time to absorb the pollutant and must subsequently be removed, always with the use of boats and then must be packed and carried landfill. Another possibility is to use a skimmer (with brushes the one in Fig. 5) but, as can be seen from the picture, it is necessary that the pollutant film is really thick to have an appreciable result. TJP has designed Oil Killer own to respond to these types of intervention (Fig. A and C)

The spillage type as in FIGS. 7, 8 and 9 require “powerful” interventions because of the amount of spilled oil to be recovered that is nearly pounds if not tons. The usability of the majority of devices now on the market requires almost immediate intervention, before the oil is dispersed in a thin film in few hours.
The interventions in the images 10, 11 and 12 are performed by today’s standards; note the managing difficulty of the roll or disc skimmer, lowered into the water with ropes or cranes and then governed with continuous displacements in the patch to be removed. The image 10 highlights all the difficulty of being able to collect stains jagged oil with a disc skimmer.
The TJP devices has been designed to be able to efficiently and effectively respond to this type of emergencies .
TJP Oil Killer collects up to 0.3 m³ of oil before replacing DracOil. Its operating speed is between 2 – 3 knots and navigate autonomously, driven in the direction of the trails or patches to collect. TJP BOS with inlet pipe multiplies the extraction capacity, needs a support boat from the edge of which it is wire-guided retaining the ability to capture crude’s trails and patches.

TJP OilKiller

JP | Saturday, 25th April 2015

OilKiller
The TJP OilKiller is a special boat designed for cleaning and maintenance of closed or under coast water mirrors as: docks, marinas, waterfront, along the lake, navigable channels, the channel ports, bays, private areas of major hotels, resorts and tourist villages.
The TJP OilKiller is based on the patented disposal FLOC (FLexible Oil Collector – pat. EP2675697B1).
The TJP has in project a whole range of Oil Skimmers for heavy employments to light ones, from Oil Spill Response in disaster theatres to cleaning and maintenance of water mirrors and the OilKiller is the first and smallest model among the devices of the expected range.
The TJP patents are aimed at the realization of devices that provide a response to the need to improve the efficiency of the reclamation in the sea with interception and collection of the free surface of water mirrors.

 

TECHNICAL DATA SHEET

 

The vessel is built with several elements made in fiberglass from MDF molds obtained with the milling technique. They are sought simple geometries with the purpose to reduce the number of parts to ensure maximum simplicity and safety of assembly.

 

MOLDS
1. Outer hull divided into bottom and side;
2. Internal hull divided into deck and side;
3. SWATH divided into swath up and swath down;
4. Roof divided into roof and carter;
5. Consolle;
6. Doors;
7. Reinforcement.
The correct sizing (compliant with regulations UNI EN ISO 12215) and the choice of the most suitable materials provide the necessary structural strength, the weight reduction and a favorable cost/benefit ratio, also thanks to the sandwich construction.
The sandwich consists of a core of lightweight and incompressible material with the two faces, said skins, made of composite material.

 

CORE
They have been chosen two types of materials:

–  COREMAT,  for the internal side that is less stressed;

–  TERMANTO,  for the bottom, the deck and the outer side that are more stressed.

 

SKINS
They have been chosen various kinds of fabrics depending on the stress amount with which they have to work:
–  COMBIMAT: a fabric with optimal mechanical properties, with large weft, to be used as final layer;
–  MAT: felts for isotropic reinforcement with multi-directional orientation of the fibers, with equal strength in all directions, commonly used for the construction of composite products. It is used in different weights: first lighter to avoid marking the surface and to better follow the forms, therefore heavier until reaching the thickness or the desired resistance.
–  GELCOAT: sheets of various nature (glass, carbon, etc.) impregnated with resin and used to obtain a bright external finish, with the desired color, free of defects and weather, ultraviolet rays and water resistant.

 

LAMINATION
It has been given particular attention to the overlap of the different materials in correspondence of fittings and joint areas, to have the best performance and quality of the final result.

OilKiller
TJP OilKiller è un battello speciale progettato per pulizia e manutenzione di specchi acquei ristretti e sotto costa quali: darsene, porti turistici, lungo mare, lungo lago, canali navigabili, porti canale, baie, aree private di grandi alberghi, resort e villaggi turistici.
TJP OilKiller è dotato del dispositivo brevettato FLOC (FLexible Oil Collector – brev. EP2675697B1).
TJP ha in progettazione una intera gamma di Oil Skimmer per applicazioni da pesanti a leggere, dall’Oil Spill Response in teatri disastrosi alla pulizia e manutenzione di specchi acquei ristretti e OilKiller è il primo e il più piccolo dei dispositivi della prevista gamma.
I brevetti di TJP sono finalizzati alla realizzazione di dispositivi che diano risposta all’esigenza di migliorare l’efficienza della bonifica in mare nella intercettazione e raccolta del pelo libero della superficie d’acqua.

 

 

SCHEDA TECNICA

 

 

Il battello è costituito da diversi elementi in vetroresina ricavati da stampi in MDF ottenuti con la tecnica della fresatura. Si sono ricercate le geometrie più semplici con la finalità di ridurne il numero e garantire la massima semplicità e sicurezza di assemblaggio nonché il miglior rapporto prezzo/prestazioni..

 

STAMPI
1. Scafo esterno suddiviso in fondo (bottom) e fianco (side);
2. Scafo interno suddiviso in calpestio (deck) e fianco (side);
3. SWATH suddiviso in swath up e swath down;
4. Tetto suddiviso in tetto e carter;
5. Consolle;
6. Portelli;
7. Rinforzi.
Il corretto dimensionamento (conforme alle normative vigenti UNI EN ISO 12215) e la scelta dei materiali più opportuni garantiscono la necessaria robustezza strutturale, il contenimento dei pesi e un favorevole rapporto costi/benefici, anche grazie all’adozione della costruzione in sandwich.
Il sandwich è composto da un’anima in materiale leggero e incomprimibile con le due facce, dette pelli, realizzate in materiale composito.

 

ANIME
Sono stati scelti due tipi di materiali:

–  COREMAT,  per il fianco interno meno sollecitato

–  TERMANTO,  per il fondo, il calpestio e il fianco esterno più sollecitati.

 

PELLI
Sono stati scelti diversi tipi di tessuti a seconda degli sforzi a cui sono sottoposti:
–  COMBIMAT:  tessuto con ottime proprietà meccaniche, a trama grossa, utilizzato come strato finale
–  MAT:  feltri di rinforzo isotropo con orientamento multi-direzionale delle fibre, con uguale resistenza in tutte le direzioni, comunemente usati per la costruzione di prodotti in materiali compositi. Si utilizza in pesi diversi: prima più leggero per non marcare la superficie e seguire meglio le forme, quindi più pesante fino al raggiungimento dello spessore o della resistenza desiderata.
–  GELCOAT:  fogli di varia natura (vetro, carbonio, ecc) impregnati con resina e utilizzati per ottenere una rifinitura esterna brillante, del colore desiderato, priva di difetti e resistente agli agenti atmosferici, ai raggi ultravioletti e all’acqua.

 

LAMINAZIONE
Particolare attenzione è stata data alle sovrapposizioni dei diversi materiali in corrispondenza di raccordi e zone di giunzione per garantire prestazioni e qualità del risultato finale.

The Intuition

it is about a device able to intercept and collect oily pollutant floating on the surface of seas, lakes and rivers. The device is simple, scalable, easy to be used and very effective. It is under protection of the European Patent # EP2675697B1.

FLexible Oil Collector

it is the device’s name, with the acronym FLOC.
FLOC performs the function of intercepting the water and pollutant surface film and to convey it towards a picking up zone. The taking up can be accomplished both with innovative TJP DracOil device as well as with traditional systems such as: oleophilic disks/rollers/brushes, weir skimmers, adduction by pipe on board support ships equipped with decantation tanks or DracOil filter-tanks.

 

FLOC

floc-2

it is a flat funnel designed to generate inside itself a balanced stream in which the inlet flow is the same amount of the sum of outlet flows and this because of the the movement and the auxiliary systems.
The main characteristics are:

  • an inlet mouth with adjustable draft to dissect and incorporate a surface film of the liquid mass
  • a tapered shape in plan and ascending side section
  • a balanced stream inside itself
  • a separating baffle of the free surface of the liquid mass
  • an outlet discharge of the deep mass of water, may be equipped with an exctractive propeller
  • an accumulation area of the intercepted free water surface

 

diagramma colorato del flusso in fianco

 

FLOC performs the following functions:

  • intercepts the surface film “F”
  • separates “F” in the two flows “FR” e “FS”
  • conveys “FR” toward the pickup area
  • discharges “FS” in deepness

 

schema imbuto-03

 

Advantages

  • autonomous movement toward the patch to be taken (see chart comparison between semovent skimmer vs fixed point skimming)
  • assenza di onde di pressione davanti alla bocca
  • adattabilità a diversi sistemi di prelievo
  • estrema semplicità costruttiva
  • scalabile

Evolution of the TJP Design

 

 

Intuition comes out from the observation of the action taken on spill responses in:

 

 

sul Fiume Lambro

the River Lambro

nel Golfo del Messico

and in the Gulf of Mexico

The goal was to find out a “system” that would allow rapid and enough effective responses and, in particular, the attention was focused on the development of events on the River Lambro.

beelotThe BeeLot comprise the existence of a River Po consortium of owners of barges that, having changed them with suitable coupling systems, could turn very quickly in suitable response to provide the first aid in case of spills in the river and its tributaries.

The next disaster in the Gulf of Mexico highlighted even more the inefficiency of the systems and the means used and the need for interventions aimed to recover huge quantities of pollutant. The idea of the mouth of the BeeLot was thus transformed into a huge plate funnel, able to float and FLOC Convoytowed by tugs within the patches to be reclaimed: The FLOC Convoy. The collected and intercepted pollutant would have to be pumped on board tankers and then to the following separation by centrifuge and storage in the tanks of the ships. The first scale model of that flat funnel was created and tested in the towing tank of the University of Trieste and the result of those tests has been the cause of the continuation of the development of the original idea.

 

primo test

primo test

The mouth device thought to be mounted on barges to collect pollutant has become so FLOC, a flat funnel, and its positioning in front of the bow of the barges has given the pattern for the architecture of OilKiller, the boat that houses and manages FLOC.

 

The next steps were driven by the decision to start a verification process of the chance to transform an idea into a business, and thus the subsequent and more thorough analysis of existing markets, the potential customers and the possible new markets.

We oriented our attention to the prevention and maintenance markets this due to the facts that disasters are neither predictable nor desirable and to keep sustainable the costs of research and development. In addition the studies we have done about the oil spills, both large and small, have illuminated us about some innovative filtration and storage systems.TJP Oil Killer

The size of the device have been thus greatly reduced and the concepts of self-propelling and self-sufficiency have taken consistency. New models have been made and tests have been continued in the towing tank. New markets have been hypothesized and for each of them have been imagined a specific product.

 

So they are born:

il pattugliatore

 

The patroller skimmer driven by a sailor and equipped with a filtering and storage system with totally clean operating cycle (as for all the TJP devices).

 

 

 

 

 

 

4-OilKiller-W

The wire driven skimmer for oil spill response work: it is lowered into the sea from a support ship, it is driven with a cable from the bridge of the ship and the water and pollutant mixture is pumped on board to be treated and stored.

 

 

 

 

OP 1-R

The patroller robot for cleaning, maintenance and alarm activities within restricted areas of activities at risk such as refineries, coastal depots, oil terminals and offshore platforms. The device provides for the use of electric motors powered by lithium batteries, the capacity of self recharging of the batteries, a station for continuous hydro-analysis, a computerized program of work, the ability of alarm and emergency, the ability of auto signaling of itself to third ships and implementation of emergency routes.

 

 

 

On bOard S.O.S.

 

The emergency device with which to equip commercial vessels in order to provide them with the ability to clean up their accidental spills and/or respond with intervention in case of found at sea of third party accidental spills.

 

 

e-LP-3-D

 

 

A device for maintenance, cleaning, patrolling and anti-intrusion alarm for areas with a high standard of welfare.

 

 

 

 

Along the way we also came across some operators need to collect floating solids, algae and mucilage; so we have analyzed in detail the muciskimmer01-render01problems which arose and the possible solutions. At the moment there is possible to fulfill that task but we have had some ideas that could give good results but there is also the need to pass through deep studies of an innovative Venturi pump. We will, in the future!

 

 

And so we come to the definition of the “concept” from which to design “OilKiller”, our first industrial prototype.

 

TJP Oil Killer

 

We have created a special real model to validate the numerical flow virtual simulations; we verified FLOC and modified the vessel’s hull in order to make it more stable on the water surface. The latter operation resulted in the elimination of the floating tubular means in favor of submerged floating systems SWAT type. Subsequently to the awareness that the industrial prototype has also to be our first demonstrator, it was decided to size it so that it was easy to transport and trailerable.

In summary:

The device “TJP OilKiller” is efficient and effective in intercepting and collecting the free surface of a water mass.

FLOC (FLexible Oil Collector) is a flat funnel under European Patent (EP2675697B1), invention of TJP, which thanks to its shape intercepts and collects the water surface with the above it floating pollutants.

“TJP OilKiller” is the industrial prototype of a boat for cleaning and maintenance of narrow mirrors of water, such as docks, marinas, waterfront, lakeside etc.

The reasons for this choice depends on:
1) the continuity of the maintenance market against the occasional and undesirable catastrophic events
2) the absence of an offer specifically aimed at cleaning and maintenance
3) by the interest shown by potential users of a similar device
4) the perception of the possibility of programming sales and therefore production and financial management

OilKiller is the first result of the process of development and optimization of an idea born in response to the need to improve the efficiency of remediation of oil spills at sea.

The original inspiration comes from the observation of the means and methods adopted at spill response in the Gulf of Mexico and in the river Lambro.
The goal was to design an efficient and effective device for the interception and collection of the free surface of a water mass.
The FLOC (FLexible Oil Collector) is a kind of flat funnel, invention of The TJP EP2675697B1 Patent, which efficiently performs the task of intercepting and collecting, thanks to its shape.
The first considered devices and prototypes have been projected to the goal of the Oil Spill Response, but the subsequent analysis of the market, competitors and users, has led us to the determination of having to produce the first boats to cleaning and maintenance of stretches of water and confined to the coast, such as docks, marinas, waterfront, lakeside etc.
The reasons for this choice are essentially:
1) The continuity of the maintenance market against the infrequent and undesirable catastrophic events
2) The absence of a dedicated offer aimed at cleaning and maintenance
3) The interest shown by potential users for a similar device
4) The perception of the programming possibilities of the sales and therefore of the production and the financial management

The TJP Convoy involves the construction of a funnel of flexible material, governed by special floats, capable to pump on board of a support ship the collected mixture for the needed separation (with DracOil or other device) and for the storage in tanks. It 'the first interpretation of FLOC, in theaters of major disasters.FLOC Convoy
FLOC is under the European Patent EP2675697B1 "Dispositivo e metodo di recupero di sostanze solide e/o liquide galleggianti in una massa liquida"
FLOC
FLexible Oil Colltector
The FLOC is a sort of flat funnel with adjustable suction mouth; it intercepts and collects a film surface in a water mass; the tapered shape generates inside itself a balanced flow that focuses the pollutants to the aft, a separator plate eliminates the bulk of the water and at stern there are the accumulation and the removal of the pollutants.
The FLOC focuses at the aft the mixture of water and oil that intercepts and collects: this stream is then subjected to the next separation treatment and the storage.

floc-1

L’intuizione

è relativa ad un dispositivo per l’intercettazione e la raccolta di inquinanti oleosi che galleggino sulla superficie di mari, laghi e fiumi. Il dispositivo è semplice, scalalabile, pratico e molto efficace ed è tutelato dalla concessione del brevetto europeo EP2675697B1.

FLexible Oil Collector

é il nome dato al dispositivo, con l’acronimo FLOC.
FLOC svolge la funzione di intercettare la pellicola superficiale di acqua e inquinanti e di convogliarla verso un’area di prelievo. Il prelievo può essere effettuato sia con dispositivi innovativi, come il serbatoio-filtro DracOil di JP, sia con sistemi tradizionali: dischi/rulli/spazzole oleofile, stramazzi (weir skimmer), adduzione a bordo di navigli d’appoggio dotati di serbatoi di decantazione o di serbatoi-filtro DracOil.

FLOC

floc-2

è un imbuto piatto, disegnato affinché al suo interno si generi un flusso bilanciato in cui la portata in ingresso è uguale alla somma delle portate in uscita, per effetto del movimento e di sistemi ausiliari.
Le sue caratteristiche principali sono:

  • una bocca con pescaggio regolabile per sezionare e inglobare un film superficiale della massa liquida
  • una forma rastremata in pianta e crescente in sezione laterale
  • un flusso bilanciato al suo interno
  • un setto separatore del pelo libero dalla massa liquida sottostante
  • uno scarico circolare, eventualmente dotato di elica d’estrazione, della massa d’acqua di profondità
  • un’area di accumulo e intercettazione del pelo libero e degli inquinanti

FLOC svolge le seguenti funzioni:

  • intercetta la pellicola superficiale “F”
  • divide “F” nei flussi “FR” e “FS”
  • convoglia “FR” verso l’area di prelievo
  • scarica “FS” in profondità
