OCIMF Tanker Managers and Self Assessment (TMSA) has since its conception turned into an absolute requirement for all tanker companies that intend to carry cargo for oil majors or their affiliates. We led the first implementation project for our previous employer in 2004, and have since been responsible for improving management systems to meet the successive revisions in two companies. We have experience with TMSA auditing by Shell, BP, IMT and several others. Based on this experience we offer gap analysis of your management system towards the latest TMSA revision. The analysis will provide you with a clear indication of the present level of compliance. Suggestions and roadmap towards improvement will be provided.
