in the shipping industry, machinery and engine failure has been cited as the foremost cause of shipping incidents. Thus, ship owners and operators are now focused on achieving a safe and reliable ship system throughout a vessel’s lifespan through effective maintenance.
This is very important for offshore supply vessels like anchor handling tug and supply vessels, as they serve a combination of function in the maritime sector.
An efficient maintenance system is crucial for increasing operational efficiency, reducing costs, and ensuring safety and reliability of vessels.
The challenge amongst ship operators is to identify the most critical components of the various systems present in the vessel.
In this paper, a failure mode and effect analysis are used to assess the possible risks of components failure in the main engine system of an anchor handling and tug supply vessel operating off West Africa waters.
Multiple experienced subject matter experts through questionnaires identified the main engine as the most important system of the anchor handling tug supply vessel, and data from the vessel owners were analysed and used to identify the most critical components of the main engine system.
The result allowed for a wider variety of opinion in selecting the most important system of the anchor handling tug supply vessel. Also, the risk assessment of the main engine was crucial in identifying the most critical components of the main engine.
