“…Many navies around the globe face the same challenges of achieving high asset availability, albeit the situation is aggravated due to the complex nature of warships [27]. Modern navies such as Italian and French Navy [4], United States Navy [28], Royal Malaysian Navy [29] and Korean Navy [30], have specified targeted operational availability targets, but it is interesting to note that availability is still a problem even in the United States Navy [28] even lately. Any effort resulting in an increase of ship operational availability is commendable [31].…”

Rapid development of shipbuilding and ship repair industry in recent years has been increasingly transforming the way organizations apply the long term strategic thinking of "cradle to grave" maintenance approach in order to maximize their growth in a dynamic marine industry. With increased ship complexity, size and revolutionary design, organizations strive to balance ideal maintenance philosophies against on-going efforts of cost reduction whilst maintaining high availability of vessels. Despite aspiration and efforts to improve the ship availability, the Royal Malaysian Navy [RMN] vessels which are currently maintained under the In Service Support [ISS] Contracts are hardly tackling the human and equipment related aspects due to limited knowledge and available data on ship Downtime Influence Factors [DIFs]. The current research carried out an explorative study across various engineering disciplines to generate RMN ship maintenance DIFs and their severity measures via a 3-Stage Modified Delphi approach. 30 Experts experienced in daily implementation of naval ship maintenance contracts were involved. In the first stage, Focus Group Discussions [FGDs] amongst Experts were conducted to produce the DIFs, followed by questionnaire distribution to measure the severity of the DIFs in the second stage. In the third stage, the Severe DIFs were confirmed and ranked based on a Risk Assessment method. The study revealed 50 DIFs to RMN ship availability and deduced the top 15 Severe DIFs pinpointing the key problem areas to prioritize efforts in improving RMN ship availability.

“…Nicolai & Dekker, 2008;Marais et al, 2013). Moreover, while typically the focus has been on the decision about the optimal maintenance interval, i.e., when to replace, the key decision for the LRU definition problem is at what level within the indenture structure of a physical asset to define the LRU, i.e., the decision on what to replace.…”
