Philosophies and Basis
DOF Subsea 5
- DNV RP H101 – Risk Management in Marine- and Subsea Operations
- Minimize Manual Handling- Proven and robust methods and design- ALARP Principle- Clear “Safe Hold Conditions”- Avoid parallel operational activity
- “One Team Approach”- Target ownership, relations and commitment;
- Client- Contractors- SubContractors- Third Parties
- All involved early
- HSE Focus- Continuously focused from day one- Always on the agenda- Allocated resources
