Design overview Regional ECOFeeder The ECOFeeder has been designed and optimised for low emissions per container slot. This has been achieved by optimising intake and by reducing turn-around time in terminals. The ECOFeeder has been designed using the ‘opentop’ concept, where containers are stowed as close as possible in open cargo holds with cell guides, readily accessible for easy loading and unloading of containers. The cell guides provides the most compact container stowage, as well as the fastest and most reliable sea fastening. The high side-structures protects for green water, ensures sufficient flooding angles and provides good structural support to the stack-cells and to the hull girder strength. In order to optimise the access to containers, the conventional tall accommodation block with navigation bridge has been replaced by an accommodation and ship control area above the engine room and aft mooring deck, which allows stowage of containers above. In order to ensure safe navigation and look-out, the vessel is operated by a ‘virtual bridge’ at the ship’s control centre (SCC), which combines the navigation bridge, ship control room and engine control room. The virtual bridge is connected with video (CCTV) and sensor signals from the forward part of the vessel, using latest technology. For safe navigation in ports, approaches and sheltered waters, a small auxiliary wheelhouse is located in the upper part of the bow. Various propulsion concepts have been evaluated, considering a typical operational profile for feeder vessels of this size. The ship is propelled by a single large CPpropeller (Kappel design), direct coupled to a two-stroke dual-fuel marine diesel engine, which provides lowest SFOC and efficient operability in terminals. The engine is suitable for both heavy fuel oil, low-sulphur fuel oil, marine gas oil or LNG. The auxiliary power is generated by a highly efficient in-line shaft-generator with variable frequency, which is backed up by two diesel generators. A battery pack is included in order to reduce generator load peaks and to provide power to the bow thruster during manoeuvring. 5
