Ship availability oriented contract management model for in-service support contracts of naval vessels

The rapid development of the ship building and ship repair industry in recent years has transformed the way organizations perceive the future industry growth.

The developed SI highlights that almost 45% of the downtime causes are due to the top five severe DIFs with corrective maintenance (SI 0.142) ranked first, spares availability (SI 0.082) ranked second, cash flow shortages (SI 0.078), ranked third maintenance budget allocation ranked fourth (SI 0.075) and knowledge management including training and skills (SI 0.070) ranked fifth.
