A new type of construction vessel could make projects such as the installation of tidal energy turbines feasible in more places.
British marine renewable energy specialist Mojo Maritime and Hamburg, Germany, headquartered shipowner Hammonia Reederei have signed a Memorandum of Understanding to finance and build the HF 4 High Flow Installation Vessel.
The HF 4 has a twin hull configuration designed by Voith and is powered by four Voith Schneider Propellers (VSP) giving it the ability to operate in currents up to ten knots using dynamic positioning Engineered by Voith naval architects, the design is based on Mojo Maritime’s vision of a vessel designed to install tidal energy turbines in high energy tidal streams. With a length of 59.5 meters and a beam of 28.6 me-ters, the HF 4 has an open deck space of approx. 1,000 sq.m, accommodates 44 people and has a maximum A-frame crane lift capacity of 250 tons.
With these specifications, it can handle all tidal energy work tasks from the installation of the turbine support structure to the mounting of the turbine and the long-term maintenance of the unit. It also has a much wider potential, including in the offshore wind sector and more gen-eral subsea construction market.
