All of the vessels delivered beginning in 2011 have protected fuel oil tanks, which mean that the bunker tanks are located further inside the vessel in order to prevent oil from leaking into the sea in the event of damage to the outer hull.
The fast rescue boat is currently located inside a recess on deck eight rather than up on the weather deck, so that it is launched from a much lower height, providing better safety for the crew.
In order to extinguish fires on board effectively, all Wallenius vessels are equipped with water mist fire protection equipment. The system is installed in the engine room and produces a mist that effectively extinguishes the fire when needed.
To give the crew on the bridge complete control over the manoeuvring of the vessel, all of our vessels are constructed with 360-degree visibility and built-in bridge wings.
…and the environment
Reducing a vessel’s environmental impact is a very important part of the design process. One way Wallenius has approached this is to reduce the vessels’ resistance, both in the water and in the air. The air resistance has been reduced by putting a windscreen on the vessels’ front edge and lowering of the deckhouses. The water resistance has been lowered by optimising the hull shape and highly efficient rudders. The losses in propulsion have been compensated by highly efficient propellers. All in all, this significantly reduces the emission levels into the air.
Additionally, the cargo holds are designed to allow for the maximum cargo for a given vessel volume. The internal ramp systems have been simplified, and there has been a lot of focus on clean smooth bulkheads in order to simplify cargo handling and make it more efficient. Having a flexible and efficient cargo hold has a great impact on the environment, because emissions per transported unit can be reduced.
To reduce the risk of spreading invasive species through the ballast water, a non-chemical system for ballast water treatment, PureBallast, is being installed on all newbuilt vessels since 2008. Wallenius is also well underway of installing this system on our existing fleet.
