Mojo’s HF4 Demonstrates Dynamic Positioning Performance

Mojo Maritime’s HF4 has demonstrated its DP (Dynamic Positioning) performance and manoeuvring characteristics based on results of simulations recently undertaken.

Mojo Maritime has concluded the design of the advanced DP system in collaboration with GE and Voith Turbo and it has been tested in DP simulations and ship-handling simulators respectively. These systems provide an accurate model of vessel DP and handling capability.

The target was to develop a vessel with the ability to hold station to a tight footprint in current of up to 10 knots- this dramatically exceeds the capabilities of any vessels currently on the market, thereby providing major risk and cost reductions across a range of industries and operations.

An extensive list of scenarios has been simulated based on a wide range of real-life operational and worst case situations. These scenarios have included failure of a thruster during operation, which is the worst single-point failure expected when operating in harsh environments.

Toby Bates, DP Training and Development, Mojo Maritime said:

“The vessel was able to maintain station even in very extreme environmental conditions- 10 knots of currents combined with 50 knot winds and 3m waves. We then failed the thrusters and systems and amazingly the vessel lost a small amount of position yet recovered within seconds.”

Richard Parkinson, Managing Director of Mojo added:

“Compared to a conventional vessel she is able to operate with current and wind from any direction, which makes set up on site much quicker and much more flexible. We are planning for the first vessel to be delivered in June 2016”
