Operational Motion Forecast
Operational Motion Forecast
ORCA Offshore provides a web based life Operational Motion Forecast service for offshore transport and installation projects. This service will give the offshore installation manager life forecast on the motions and loads in the system based on the most recent weather forecast. This information can be used to take the start, stop or continuation decision for critical offshore operations.
The OMF service integrates ORCA Offshore’s multidisciplinary expertise across computing technology, offshore operations, weather dynamics and vessel hydrodynamics, ensuring reliable and accurate results for critical decision-making.
The Operational Motion Forecast (OMF) service will be setup before the start of the operation by preparing a full 3D dynamic model using the multibody motion software MOSES. With the results of this model, the actual response of the model will be analyzed for each received weather forecast and the results of this analysis will be forwarded to the offshore crew.
Using the prediction of this system the decision to start, proceed or stop can be taken on a much better basis. The service includes support by a senior Naval Architect who will prepare and monitor the data before it is send to the offshore crew for their use.
This service is unique for the offshore industry and has the potential to reduce weather down time and weather risks for critical offshore operations without the need for any additional hardware on board. The service can be setup for any kind of transport or offshore construction project, and includes a full dynamic analysis report and a OMF system description manual for Marine Warranty Surveyor review and approval.
Dynamic Analysis
The Operational Motion Forecast (OMF) service will be setup before the start of the operation by preparing a full 3D dynamic model using the multibody motion software MOSES. The results of this model will be available through our servers and the performance will be monitored by an experienced Naval Architect before the results are sent to the ship.
Weather Forecast
OMF can use various sources of weather forecasts. When the new weather forecast is received all forecasted environmental conditions are defined as a loadcase and run in time domain or frequency domain through a dynamic model of the operation to forecast the responses of the operation and determines the Utilization Factors based on the defined safety factors.
WEB Utilization View
Through a web interface the Utilization of the operational limits will be presented together with the weather forecast. This information will show the offshore crew the actual forecasted behavior of the ship or offshore operation. The above view shows response details for a selected operation step. If needed a full pdf report can also be downloaded.
WEB Response view
This example shows the Polar plot used to determine the optimal heading for the planned operation. The tool can be used to support the decisions to change the operational plan to fit the weather forecast on the day and provide the documentation to fit your management of change system.
