Wärtsilä has secured a contract to supply a range of solutions for six new 1,160 TEU vessels. They will be constructed at the Fujian Mawei shipyard in China.
The project has been developed by MarLink Project Management in Germany together with various investors. The vessels have [ds_preview]been designed by German design office abh Ingenieur-Technik. There are options for a further six vessels.
The full Wärtsilä scope for each vessel comprises the main propulsion unit featuring a controllable pitch (CPP) propeller plant including the shafting arrangement with a step up tunnel gear, the manoeuvring unit comprising a bow tunnel thruster with the electrical motor and variable frequency drive (VFD), a custom designed shaft generator system, a hybrid exhaust gas cleaning system, ballast water management systems, a sewage treatment plant and the ship automation. The equipment is scheduled for delivery to the yard commencing in the second half of 2017, and the first vessel is expected to be delivered in 2018.
According to the Finnish manufacturer the CP propeller plant has been tested extensively in model scale where it has been proven to be superior in terms of efficiency, cavitational behaviour and robustness.
The newbuildings will get a hybrid scrubber plant
In preparation for the IMO‘s sulphur cap regulations due to take effect in 2020, these ships will be equipped with a Wärtsilä hybrid scrubber plant. The system is operated with seawater in open and closed loop, and is designed to comply with the 2020 regulations‘ global 0,5 % sulphur cap, as well as with the even more stringent cap of 0,1 % in defined SECA zones. When operating in closed loop, the wash water will be cleaned extensively to safely comply with the IMO‘s discharge rules. The vessels will run in zero discharge mode for a defined period of time when operating the exhaust gas cleaning unit. The venturi type integrated scrubber will clean the exhaust from the main and three auxiliary engines.
