Yanmar provides the power for CTruk’s THOR Project

The Special Projects Team at E. P. Barrus Ltd is pleased to be involved with CTruk’s THOR (Twin Hulled Offshore Raider) project, a new multi-role force protection craft.

Marine Diesel Inboard Engines

Barrus has supplied twin Yanmar 8LV, 4.46 litre, 370hp (272kW) marine diesel inboard engines to power this impressive and innovative craft. In the Yanmar tradition of high power from low weight, the dry engine weight is just 435kg without the gear box. Additional benefits of this engine include exceptionally low noise levels, reduced vibration, and ease of installation and servicing. The Special Projects Team has also provided full engineering support including additional 24v alternators to power the control system of the Rolls-Royce Jet Drives and a modified water pump mounting position for improved accessibility.

CTruk’s Military and Security Team and their Military Design Advisory Panel (MDAP) are responsible for THOR. The 11m,  multi-role vessel has been designed to fulfil a number of roles, including force protection of the amphibious sea lanes, casualty extraction from a beach, carrying and deploying a pre-landing force, riverine patrol, protection of harbours and offshore installations, unmanned surface vessel operations (for protection and mine countermeasures) and disaster relief. THOR is a high-speed vessel suitable for sustained operations over long distances and time periods.

“Our long, and successful relationship with the UK MOD, was a key factor in our selection by CTruk to work on the THOR project. The Yanmar 8LV also offers the highest power to weight ratio in its class contributing to CTruk’s design requirement to reduce the overall vessel weight resulting in greater payload, range and speed, commented Mark Coleman, General Manager Special Products and R&D Divisions, E.
