ECOCEANE® vessels are designed for the recovery of hydrocarbons in deep-sea, coastal areas, large ports and small harbors. Their supply functions (multi-purpose work boats) allows them to perform an economic activity during oil spill standby periods.

One product to solve all weaknesses of traditional equipment.

1- QUICK RESPONSE

Acting as autonomous cleaning systems, our ships recover hydrocarbons with a working speed up to 4 knots, filling their own storage capacities. Deployment takes less than 3 minutes.

2 – COLLECT BOTH FLOATING SOLID WASTE AND OIL, ON THE RUN

without creating emulsion): The Double Flow technology makes it possible to actively collect both floating debris and any hydrocarbon pollution.

3 – OPERATING IN CHOPPY WEATHER CONDITIONS

Self-floating arms allows to follow the waves independently from the boat’s movement and thus allowing to collect oil in up to Sea State 6.

4 – SEPARATING THE TRANSFER FROM THE RECOVERY

Ships have, depending on their size, self-cleaning storage capacities. But can also transfer as they collect for unlimited capacity working 24/7.

5 – TAKE THE MAN OUT FROM THE HAZARD

All hydraulic controls actuating the various cleanup functions are controlled from the wheelhouse. No man on the deck handling heavy equipment and in contact with hazardous waste and toxic gases.

Ecoceane a profitable business model

The pollution control equipment is an integral part of the ship and is thus always available for immediate response.

During the major oil spill in the Gulf of Mexico, the use of 4 REVERSEGLOP or SPILLGLOP plus 8 tankers (to store pollution) would cost less than 1/1000th (one thousandth) of the cleaning cost and allowed the recovery of all the spilled oil, avoiding the use of dispersants whose ecological consequences are poorly understood.

For a 25 m vessel capable of collecting 120 m3/h or 50 000 m²/h, only 4 crew members are required, leading to a very low operating cost.

Before and after this period, a SPILLGLOP is not on standby, it will work as a « supply» for the oil service, transporting crew and merchandise, towing, lifting, FIFI, rescue, etc.

Ecoceane vessels are versatile : service + cleanup.

1 – Quick Response

Ecoceane’s technology is an autonomous built-in cleaning system, making the deployment (going from navigation mode to cleanup mode) in only 3 minutes.
The ships recover hydrocarbons with a working speed up to 4 knots.
The recovery is active, allowing the vessels to be extremely mobile and maneuverable while recovering oil.

2 – Collect

Double flow technology

A flow is created in the front to suck-in the floating pollution. Self-floating arms are deployed to increase the width of collection. This flow, generated by a turbine, passes through a mesh in the shape of a basket (2) which stops all the solid waste and lets the hydrocarbons through inside the storage/separation tank (3).

From the basket, the flow is separated into two parts:

  • 1st flow: The turbine pumps away the clean water (lower layer) through the bottom tunnel,
  • 2nd flow: Surface water polluted with hydrocarbons (top layer) goes into the separating tank where the pollutants can be stored, floating, in a thick layer without creating any emulsion

Once a thick layer of oil is created it can immediately be transferred to another mean of storage (towed barge, tanker, floating bladder, etc.) if the own storage capacity is not enough.

Hydrostatic pressure equilibrium

All vessels are preliminary tested with Computational Fluid Dynamic CFD software named Abaqus Fluid movement and cleaning capacities with oil by solving Eulerian/Lagrangian equations.

As an example, a Spillglop 250 has the following specifications.

Realistic recovery performance is between 9,000 m²/h and 49,000 m²/h. Corresponding to 13 to 74 m3/h, with a surface distribution of 15 % (meaning 15 % of the cleaned surface is composed of hydrocarbons) in a layer of 1 cm thickness. For a surface distribution of 30 %, the values are 27 to 148 m3/h.

Self-storage capacity of oil is 120 m3.

3 -Operating in choppy weather conditions

The self floating arms are connected to the boat by a rotating shaft, which enables them to ride the waves independently of the boat. All of the surface pollutants trapped by the arms are sucked up into the boat.
At a speed of 4 knots, the ECOCEANE boat can be followed by a tanker. The vessel is designed for solid and liquid floating waste recovery operations even in the most inaccessible places, capable of working in difficult weather conditions.

Self-floating arms are connected to the vessel by a rotation axis which allows them to follow the waves independently of the vessel. All pollution trapped within the arms’ reach is sucked inside the ship.

This patented system acts as a wave dampener (dampening of horizontal energy, dissipation of vertical energy, absorption of energy by friction, smoothing of the free surface) that makes Ecoceane’s ships the only ones in the world able to provide cleanup operations up to Sea State 6/7.

4 – Separating the transfer from the recovery

Ships have, depending on their size, self-storage capacities.

Nevertheless, in case of a major spill, they can continuously transfer the recovered oil to rotating tankers, which ensure the transportation of oil to the shore, and allow cleaning operations 24 hours a day.
Ecocean’s technology transfers only pure oil as the separation of oil and water is done before transferring.

5 – Take the man out from the hazard

Living areas are protected.

ATEX (explosive gaz detectors) can be fitted in.

Antisparks fittings are installed on venting pipes.

All hydraulic controls actuating the various cleanup functions are controlled from the wheelhouse. The crew is not required on deck and thus no direct contact with dangerous products is possible, neither is the handling heavy equipment.

All our ocean-going vessels have the Oil Recovery Ship classification from Bureau VERITAS.
