Ship Hull Maintenance: Scheme for Condition Monitoring and Maintenance Planning

M. Maran, Anchit Vijayakumar, B. Chendur

Abstract


Any organization that is responsible for procuring and managing complex assets should have an effective maintenance planning. Due to the complexity and the obligations on shipping organizations to comply with regulations and requirement maintenance planning is very important in the marine shipping industry. Moreover improper planning can lead to breakdowns and reduce the availability of the ships, which could increase the cost of maintenance and reduce the revenue of the company. Maintenance is a significantly essential feature of the national economy. Maintenance can no longer be ignored as the cost of maintenance labor is increasing faster than the index of total plant operation costs dictates increased prudence in spending on maintenance activities. This paper provides a framework that can help decision maker choose the optimum decisions regarding the ship maintenance. The key factors that affect the ship maintenance planning like maintenance scheduling, selection of maintenance strategy, ship construction and shipyard selection are discussed in this paper. Identification of problems is easy with the inspection regimes, which is performed by the ships crew and shore staff. Risk-based decision-making technique has showed great potential in identifying key structural element and focusing more resources for maintenance and inspection. The hull is divided into compartments and these are scored after the inspection as good, bad and poor. A list containing the damages and the repairs to be done can also be generated using the scoring system, which can be used for future dry-docking event.
