Swedish system integrator METS Technology has, together with main contractor Ö-Varvet AB, decided on EST-Floattech’s new Octopus Series battery system for the retrofitting of the MS Hamnen. The MS Hamnen is a Gothenburg Port Security vessel, built in 1979.

METS Technology focuses on developing energy-efficient and environmentally friendly solutions for different ships or offshore installations. Shipyard Ö-Varvet will conduct a major rebuild of the Hamnen to make it more future-proof. Included in the works is replacing the diesel engine by a parallel hybrid system with Power Take Off/Power Take Inn functionality.

Four hours at six knots

EST-Floattech will deliver the Octopus High Energy Battery System, tailored to the space available on the MS Hamnen and the energy requirements. Shipyard Ö-Varvet has designed a battery compartment in collaboration with METS. The battery system provides flexibility, and there is space reserved for an additional battery pack if the shipowner is looking to expand the battery capacity in the future.

The batteries will provide enough power for the vessel to sail for at least four hours at six knots, and will also provide energy for the vessel’s hotel load and the bow thruster.

‘Fitting a battery system is often about weight and dimensions. Especially when it comes to a refit, the available space is limited. However, the Octopus system offers great flexibility to make optimal use of the available space,’ says Jelle Meindertsma, Sales Manager.
