The HiLoad DP Side Loading (DSL) system has been developed to overcome the challenges given for traditional side by side systems. The conventional LNGC is maneuvered towards the FLNG by use of the DP system on the HiLoad LNG, removing the need for tugs. The heading control is enabled using the LNGC rudder and main engine in constant “Dead Slow Ahead” mode.
Simulations of the DP station keeping and heading control capability of the HiLoad LNG docked to a LNGC have been conducted. A large LNGC was used in the simulations, representing more than 95% of the world-wide LNGC fleet in operation.
Simulations were performed for several conditions, specified by a wave spectrum, wind spectrum and current speed and their directions.
