Wärtsilä said it launched a series of four new container feeder vessel designs based upon achieving optimal fuel efficiency while being compliant with all known current and future environmental regulations.
The four ship designs, namely the WSD80-1500, WSD80-2400, WSD80-4000 and WSD84-2400, feature low fuel consumption. Each design is available in three versions; ‘conventional’ using HFO as fuel, ‘environmental’ using HFO with exhaust cleaning scrubber systems, and ‘clean’ with dual-fuel capability and running mainly on liquefied natural gas, the company informed in a statement.
Wärtsilä’s ship designs anticipate the global adoption of LNG as a marine fuel. Fuel flexibility is, therefore, a main feature of these latest Wärtsilä designs along with fuel efficiency, cargo capacity, systems redundancy and the lowest possible levels of exhaust emissions. Since container feeder vessels operate largely within existing or anticipated ECA (Emissions Control Areas) or SECA (Sulphur Emissions Control Areas), environmentally compliant designs are extremely relevant.
Wärtsilä added that design solutions can be tailored according to the specific needs of the owner, achieving the right balance in functionality and new build cost.
