Outokumpu provided Forta super duplex stainless steel for a prototype of an offshore patrol vessel made by Swedish ship maker Swedish Steel Yachts AB (SSY). Outokumpu supplied mirror-polished plates in different dimensions for the vessel, which is made entirely of super duplex Forta SDX 2507 stainless steel with a very high corrosion resistance to cope with marine environment. The 17-meter long vessel with a maximum speed of 60 knots was set to sail last week on May 12, 2017 in Gävle, 200 km north of Stockholm.
The P16 prototype is built by using a design concept and inspired by the features of a traditional Viking boat. The design together with the material choice made it also possible to build an extremely lightweight ship: high strength of the duplex stainless steel allows reduction of thickness in the material used. For the ambitious project, SSY selected Outokumpu’s Forta SDX 2507 super duplex stainless steel.
All metal under the waterline is mirror-polished by Outokumpu, which ensures that marine organisms attached to the hull can be removed either with a low-pressure hose. As a result, there is no need for environmentally hazardous and expensive anti-fouling paints.
