On 28 May 2010, the Petroleum Safety Authority Norway (PSA) issued an Acknowledgement of Compliance to COSL Drilling Europa AS (CDE) for their mobile living quarters facility COSLRival.

COSLRival will be operated by OSM Offshore until 1 June 2010. The facility was previously called Port Reval and received an AoC for the first time on 3 August 2007.

CDE will assume operating responsibility for the facility from 1 June 2010. As an Acknowledgment of Compliance is the property of the shipowner (operating company), a new AoC is required in connection with the transfer of operating responsibility.
