INNOVATION AT THE SERVICE OF THE ENVIRONMENT
1) The problem with current protection methods and equipment For years on a European level a great deal of effort has been put into improving pollution control, especially oil, if there is a major event. All these efforts are limited by the difficulty in recovering oil at sea effectively. This is due to the emulsion (mayonnaise) produced by the mixture of water and oil when pumping. This emulsion, which contains up to 75% water, must be treated before storage in tankers. At the moment, the collection rate depends on the time required to treat this emulsion (less than 5 m3/h). In addition the equipment used (skimmers) limits the work to a speed of 1 knot and makes collection impossible in winds above Force 3. The low recovery rate, the restricted operational range and the slow speed of the implementation of the device are the result of hydrocarbon recovery techniques which have not evolved for more than 30 years.
2) THE ECOCEANE SOLUTION ECOCEANE has designed a range of multi-purpose vessels which, as well as being real workboats, recover all floating waste, whether solid or liquid, with results that are twenty times better than with the existing equipment. ECOCEANE vessels have all the equipment for collecting hydrocarbons at sea incorporated into their structure, acting as true “hoovers” on the surface of the sea. The pollution layer is sucked up by the vessel without creating an emulsion. The hydrocarbons are stored floating in a thick layer in the separator and then transferred continuously using an on-board pump directly into oil tankers or storage barges. Rotation of tanker vessels means there is no limit to the quantities that can be recovered. This solution will quickly make its mark as the model for the protection of seas and oceans.
a. WG 128 and WG160 : Workboats WG 128 and WG160 are versatile vessels which remains available in a port, has a dedicated crew and are used throughout the year as work boats. They carrie out all service tasks: • Passenger transport • Cargo transport • Maritime work • Fire-fighting • Etc.
WG 128 and WG160 are profitable during periods on watch.
b. WG 128 and WG 160 : Marine pollution cleanup vessels Available in less than 12 hours, the WG 128 and WG 160 sail to the polluted area at 12 knots, can cover more than 1000 nautical miles without replenishment and have a working autonomy of 10 continuous days. Specific characteristics ensure optimum safety for the crew: • Maltese Cross certified hull • Machine point • Bureau Veritas certified equipment • Detection system for harmful and explosive gases • Electrical system to ATEX standards • Fire insulated cabin • Hydraulic controls from the cabin (no external operations once the transfer hoses are in place)
WG 128 and WG 160 are classified by the Bureau Veritas as Category 1 and Oil Recovery Ship. They bring together all the means required for the collection of hydrocarbons at sea and only transfers oil without an emulsion. The storage vessels, tankers or barges, do not need to undergo any conversion.
3) USE The seas and oceans are common to all of Europe and pollution does not stop at the maritime borders. The means used by each country to fight pollution vary greatly and are ineffective. It is desirable to have a single European command to harmonise pollution control procedures. This organisation exists, its name is the European Maritime Safety Agency (EMSA). This European agency, which implements satellite surveillance of pollution and has good storage capacity, does not have any effective means of recovering hydrocarbons at sea. This deficiency would be filled by ECOCEANE vessels, replacing the rather ineffective equipment currently used by EMSA.
a. Organisation EMSA could deliver public service delegations to companies which would agree to maintain a WG 128 or WG 160 vessel on watch in each port with a qualified, dedicated crew, available to get under way in less than 12 hours. EMSA will be responsible: • Either for establishing an agreement with the oil tanker or “supply” owners to be able to requisition the available oil tankers in nearby waters for the areas of intervention. • Or to study the making available of 1500 m3 barges (double hull) in the home ports. Rotation of storage equipment (oil tankers and barges) will mean that the quantities of hydrocarbons that can be recovered are unlimited. WG 128 and WG 160 vessels can operate very independently. Every 12 hours 1 or 2 other WGs nearby could intervene, accompanied by their tankers or barges to reinforce the tool.
b. Advantages Unlike the current model where, if there is an alert, the vessels must go and empty their cargo and visit a home port to embark equipment, our vessels will be in any pollution area in less than 12 hours’ sailing, and capable of collecting 20 times the quantity of hydrocarbons in sea operating conditions of up to Force 6. In addition, such a tool will make it possible to put in place an economic model unsurpassed to date, by using a truly independent recovery station with an economic activity other than simply pollution control. This represents an undeniable revolution in terms of the control equipment, which until now has been immobile when not involved in pollution control.
c. Construction The ECOCEANE engineering design office designs vessels using CATIA (Dassault Système) software and provides each shipyard with plans for cutting, folding and assembly. So the WG 128 and WG 160 can be built by various shipyards. This manufacturing model demonstrates the European dimension of our project.
3 ) Conclusions In summary, the putting in place of WG 128 and WG160 would provide the following advantages: • Rate of recovery 20 times greater • Ability to work up to Force 6 • Optimisation of safety onboard • On-site intervention in less than 12 hours’ sailing • 24/24 working • Available tankers are combined in the tool and no longer need to undergo conversion work to receive the transferred oil • Profitability during on-watch periods
Our project comes within the current budget of EMSA. The performance of our vessels allows each country to make savings in its own marine pollution control budget.
