THE SITUATION
Large oil spills at sea
difficulty to act rapidely
difficulty to operate in a rough sea

THE NEED
A vessel capable to harvest oil at sea in quite harsh
conditions
A vessel that can be on site quite rapidely
A multi-purpose vessel worth to be maintain at sea all
year long

AN INNOVATIVE ANSWER : THE PLATFORM
A TRIMARAN STRUCTURECentral hull : slender monohullSide hulls : swath type
ADVANTAGES• Monohull
Course stability Reduced pitch motion High payload
• Swath Roll stability

ww.osh-project.org
OSH platform : Preliminary design within European funded project
Some preliminary work at the beginning of the project based on updated specification for the vessel (WP2) allowed to :
adapt the general dimensions of the ship to the project (displacement, storage capacities, …)
eliminate some drawbacks of the original conceptual design
facilitate the integration of the tool carriage and of the oil recovery tools
improve the general performances : nautical qualities of the platform, efficiency of the oil recovery tools in rough weather

OSH platform : Preliminary design
Major modifications were :
lengthened main hull
Side hull : round section fitted outside the channel for easier tool carriage integration
Total displacement : increased to 12000 tons, according to the updated weight evaluation.
Transverse stability: GM increase from 1 m to 2 m, according to stability rules requirements
Move accommodations forward in order to have more room on the aft part dedicated also to complementary missions

AN INNOVATIVE ANSWER : THE HARVESTING CONCEPT
•The oil slick penetrates into the two chanels between the two sides and the central hull
•These chanels are well protected from the external rough weather
•The surface of the oil slick is calmed by :– the narrowness of the chanels– The oil viscosity
•The residual mono directional sea state into the chanels is reduced
•In that choppy sea it becomes possible to recover the oil slick with the proper tools fitted on two floatable tool carriages

OIL SLICK RECOVERY TOOLS
These tools may be fitted according to the product viscosity
They are modular built types
They are fitted on the two floatable carriages
They are stored on board
They are chosen to match with the specific need

COMPLEMENTARY MISSIONS
Such a vessel would be able to carry out the following missions :
•The permanent presence at sea 350 d/y•Search and rescue•Maritime surveillance•Solid waste recovery•Chemical products recovery•Fire fighting•Offshore operations which require a dynamical positioning by high sea state 6/7 :
•Pumping from wrecks•Exploitation of submarines and robots•Etc

CONCLUSION
This concept of platform and associated tools dedicated to oil recovery but also complementary missions is to allow to :
•Operate even in high sea state•Give assistance to ships in distress•Arrive very quickly on the catastrophe spot•Recover efficiently the oil slicks by using the more efficient tool
And so decrease drastically the consequences of the oil slicks
