QinetiQ GRC's Paramarine ship and submersible design software has been selected by Mojo Maritime Ltd. to support the design of a new dynamic positioning (DP) offshore construction vessel, the HF4, which will have applications for the tidal energy industry. Mojo Maritime Ltd. specializes in marine operations, technical consultancy and project management for the offshore renewable energy sector.
The purpose of the HF4 is to reduce the installed cost of marine renewable energy devices to initiate industrialization. The vessel is designed to operate using dynamic positioning in currents up to 10 knots, allowing a high degree of accessibility and improved productivity during the construction phases of tidal energy farms. It is capable of installing foundations, cables, subsea connectors and turbines in a wide range of conditions. The development of the vessel is being assisted by the Technology Strategy Board and the Mojo lead consortium involving Voith, DNV, Bauer and the University of Exeter. Construction is planned to begin in 2014.
Mojo Maritime Ltd. will use the probabilistic damage analysis module, one of a number of new capabilities in the latest version of QinetiQ GRC’s Paramarine software - V8, which takes into account not only the vessel's stability when certain subdivisions of the ship are damaged, but assigns probabilities to various extents of damage and survivability when damaged. This is required as part of the design for all passenger and cargo vessels.
