mplementing this systematic warning and grading strategy transforms unpredictable breakdown risks into manageable maintenance costs. The return on investment is clear: Ensures Operational Continuity:Can prevent over 50% of unplanned downtime, directly protecting your revenue stream. Optimizes Lifecycle Cost:Converts potential multi-thousand-dollar overhauls into planned, lower-cost repairs. Enhances Operating Efficiency:A healthy engine is consistently more fuel-efficient than one running with underlying issues.

For port operation tugs, it is recommended to use elastic coupling connections with low-speed, high-torque propellers; for passenger ferries that require frequent start and stop, a hydraulic coupling is recommended to effectively reduce transmission system impact; for continuously operating generator sets, the cooling system configuration needs to be specially enhanced, and it is recommended to add an auxiliary cooling pump. We suggest that shipowners consider not only the initial purchase cost when selecting an engine but also the operational benefits over the entire lifecycle. According to actual operating data, the 6WH17 engine, through optimized fuel efficiency and longer maintenance intervals, can help shipowners save approximately 15% of total operating costs over five years.
