Hoegh LNG asked Amarcon to extend the OCTOPUS-Onboard Monitoring & Routing System with weather windows for Dynamic Positioning and sloshing decision support for the LNG Carrier Suez Neptune.

LNG SRV’s are exposed to waves, wind and current. One of the critical phenomena during offloading is sloshing. Therefore a heading control scenario will be implemented based on the use of weather forecasts info within a customized version of OCTOPUS-Onboard. This system includes the characteristics of the Dynamic Positioning System and will be configured for the combined use of Nowcast of waves and motions, high-quality frequent weather forecasts, standard discharge procedure, option to simulate the effect of possible variants of the discharge procedure, the DP-capability of the vessel, ship responses to wind, current and waves and limitations given in the owner’s specifications.

All the results are presented in clear displays on time scale and as actual values. The development has been done in close co-operation with Hoegh and its suppliers.
