CRITICAL ANALYSIS OF TANKER OP-EX ADJUSTING CREW SYNTHESIS, AUTOMATION LEVEL, AND MAINTENANCE

In this paper we will present a critical analysis concerning tanker operating expenses. In this context, we try to explore various possibilities for the combined adjustment of automation level and crew synthesis, in order to fulfill maintenance (operational) needs of tankers. Precedent research results have shown that by increasing vessel automation level a substantial decrease of crew synthesis is feasible, in terms of watchkeeping and safety redundancy; hence, a potential window for decrease of op-ex is produced. The crucial issues/constraints regarding the analysis for the operational viability are maintenance man-hours in accordance with policy issues on on-board workload and fatigue, and external costs in order to cover all corresponding tanker needs. This paper examines all recorded aspects of the specific problem and proposes a methodological framework. This is achieved by using certain statistical, analytical and simulation techniques so as to come up with solid results and conclusions. Main motivation for this paper is the oncoming increase of tanker build-in technological innovations versus the slowly changing policy for vessel crew synthesis. Finally, we will conclude this paper with interesting comments arisen from the aforementioned tasks.
