Goal-based procedures described in this paper provide a practical methodology for being able to demonstrate that a mechanism is in place for addressing the effects of hazards associated with an offshore support vessel’s (OSV) multiple functions and the means of mitigation selected. The tools described help the reader, through visual means, to gain an insight into the interactive relationships of the multiple functions of OSVs. With a better visualization, the functional requirements of the ‘mitigations’ are more readily and effectively captured. The mitigations can include engineering solutions or appropriate procedures, or a combination of both. The results of this paper will assist in providing guidelines, which are sufficiently clear, transparent, verifiable, implementable and achievable to all parties in the value chain, including energy majors, designers, ship builders, owners, operators, regulatory bodies and underwriters.
