MSV Regalia - audit of DP operations at Visund

MSV (Multi-Service Vessel) Regalia is operating as a dynamically positioned (DP) accommodation unit at the floating production facility Visund. In the period 9 to 11 March this year we conducted an audit on/of the unit and DP operations at Visund. MSV Regalia is operated by Prosafe Offshore Ltd (Prosafe) in Aberdeen.


The audit was carried out by having a meeting with the onshore organisation and by verifications on board the MSV Regalia.

Background for the audit

MSV Regalia is operating as a dynamically positioned (DP) accommodation unit at the floating production facility Visund. A DP system consists of power system, thrusters system and DP control system acting together to achieve sufficiently reliable position keeping capability.

During the last years we have had several incidents resulting in loss of position on units operating with DP.

Regalia is connected to Visund by a gangway which is disconnected under certain weather conditions or loss of position situations. The operations with Regalia as an accommodation unit at Visund are planned to take place in the period February 2005 till September 2005, while project work is being carried at Visund.

Purpose of the audit

The objective of this audit was to evaluate Prosafe's ability to comply with regulations related to the DP operation of MSV Regalia, concentrating on the operational aspects of DP, including training of personnel and maintenance of DP related equipment.

Result of the audit

The general impression is good, but some observations were made, especially in connection with emergency training of key DP personnel.
