dana petroleum fpso

ORCA Offshore are pleased to announce it has been involved with the berth mooring design and analysis procedure for the Dana Petroleum Western Isles floating production, storage and offloading (FPSO) unit.

The FPSO will be moored at the Keppel Verolme Quay, Rotterdam.

Scope for Orca Offshore included:

  • Prepare 3D hull model of the vessel
  • Prepare model including, mooring lines, fenders and mooring barge between the FPSO and the quay
  • Design mooring plan
  • Model directional wind data
  • Perform full intact and damaged mooring analysis following GL-ND guidelines
  • Specify mooring lines

The analysis model consisted of two separate bodies to determine the loads between the FPSO and the mooring barge.

In order to find a solution for this complex mooring, several alternative designs have been analysed for intact and damaged line condition.

The analysis has been performed with MOSES from Bentley systems using a in house developed web based interface to generate the input for the MOSES run. With this interface, it is possible to quickly change the mooring system and to review the results of the MOSES analysis.

The input control and standardised output made it easier to control all the runs and to keep track of the quality of the work.
