Abstract

As wind farms are moving farther offshore, logistical concepts increasingly include service operation vessels (SOVs) as the prime means of service delivery. However, given the complexity of SOV operations in hostile environments, their safety management is challenging. The objective of this paper is to propose a quantitative, non-probabilistic metric for the preliminary comparison of SOV operational phases. The metric is used as a conditional proxy for the incident likelihood, conditioned upon the presence of similar resources (manpower, time, skills, knowledge, information, etc.) for risk management across compared operational phases. The comparison shows that the three considered phases of SOV operation have rather comparable levels of variability, hence the likelihood for incidents. However, the interface between the SOV and turbine via the gangway system and the manoeuvring between turbines seem to show a higher potential for incidents and performance (work efficiency) shortfalls.
