L ittle is known about the mechanism of how workplace safety may affect operational disruptions manifested as unplanned maintenance in commercial vessels. Building upon the high reliability organization theory as a broad framework, we propose that workplace safety climate influences how employees identify and report errors at work. Specifically, no-blame error reporting mediates the relationship between safety climate and unplanned maintenance in vessels. Additionally, we posit that the mediation effect varies among vessels in that it is stronger (weaker) in newer (older) vessels that are easier (harder) to maintain operationally. We test the moderated mediation framework at the vessel level of analysis using an archival survey data with multiple responses from 1,169 crewmembers in 86 marine vessels. Our results lend support to the mediation effect in that safety climate facilitates no-blame error reporting, which subsequently reduces the frequency of unplanned maintenance. In particular, the effect of safety climate on unplanned maintenance is fully mediated by no-blame error reporting. As vessel owners attempt to maximize their return on investments in aging ships, the mediation effect shows a high level of safety climate in a vessel is indirectly associated with a significantly lower level of unplanned maintenance rate relative to a similar age vessel but with an average level of safety climate. However, the mediation effect weakens as a vessel ages. This study contributes to important insights into how safety climate can reduce operational disruptions (unplanned maintenance events) through error reporting behaviors, contingent upon the age of ocean carriers in logistics companies.

“…However, they focused only on the features of the platform and ignored the preferences of the users while this study takes into consideration both owner and user demands to reach the optimal combination of equipment needed to upgrade the shipyard. In another work, Temple and Collette 12 tried to optimize the production, maintenance, and resistance costs throughout the life cycle of naval vessels. Although using a genetic algorithm, like the current study, they only concentrated on costs and overlooked time factors.…”

“…10 For example, Zvaigzne et al 11 developed a decision support system to optimize the design of a specialized maritime platform based on genetic algorithms. Temple and Collette 12 adopted multi-objective optimization methods to find an optimum point in lifecycle cost trade-offs for naval vessels. They used Pareto Front to assess and optimize three objectives, including minimizing production, maintenance, and resistance costs, at the same time and a genetic algorithm to search the decision space made by decision variables.…”

The purpose of this research is to select the optimal combination of infrastructure and equipment to upgrade a shipbuilding yard to repair offshore drilling rigs considering installation time and cost of the equipment needed and the overhaul cost and time of a rig. These four components constitute a four-objective problem. To solve this problem, a list of main equipment with various capacities and installation costs was developed. Then the cost and time of overhaul of drilling rigs, as well as the installation time of equipment were extracted using the Delphi method. Finally, the SPEA2 algorithm was employed to analyze the data. An optimal Pareto combination of equipment was obtained at a cost of $242.6 million, which can be provided in a maximum period of 200 months. The findings suggest the optimum way to equip shipyards for the overhaul of drilling rigs based on time and cost optimization for both rig and yard owners.

“…Bayesian probabilistic network-based consequence models have been used to derive target reliability indices for the design of FPSOs (Faber et al 2012;Heredia-Zavoni et al 2012). A multidisciplinary optimization of vessel costs with an enhanced multiple-objective collaborative optimizer was developed for the design of naval ships (Temple & Collette 2017).…”

Some floating production, storage, and offloading units (FPSOs) possess disconnectable systems to avoid harsh environments. According to a literature survey, the practice is based on perceptions and experiences of operators to judge disconnection; however, this paper offers a rational approach. A life-cycle cost model is proposed to optimize (1) the disconnection criteria and (2) the design of mooring lines under reliability format. Relevant ultimate limit states are considered in association with hull, moorings and green water failure. Effects of future failure costs is considered (downtime, environmental damage, reputation, etc.). Disconnection criteria are then formulated in terms of significant wave height and wind speed limits. Because a permanent mooring system may exhibit excessive resistance, it is possible to reduce the lines' thickness until the cost is optimized for non-permanent service. Results for an example in the Gulf of Mexico show that important savings can be achieved by implementing the proposed optimizations.
