Operational Motion Forecast
Operational Motion Forecast
The service combines the know-how and experience of ORCA Offshore regarding computing technology, offshore operations, weather dynamics and vessel hydrodynamics which makes this service reliable and accurate.
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 this model the actual response of the system 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. This model will be setup at our servers and the performance will be checked and 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. If needed a full pdf report can also be downloaded.
WEB Response view
This example shows a Utilization and response details per Case detailed reports can also be generated showing the motions or loads of each item of interest. The report and web interface can be custom build for the client or the standard report can be used.
