MY KAPLAN Yacht Inspection

Engine Diagnostics, Electrical Faults, and Hydraulic System Repairs for Safe Operation

The inspection of MY KAPLAN focused on engine diagnostics and sensor performance. First, throttle position sensors showed incorrect signal calculations on both engines. These faults triggered alarm codes and required immediate attention from technicians. Additionally, low engine oil levels were detected on both port and starboard sides. This condition risks engine damage and reduced propulsion efficiency. Closed-loop fuel pressure was also found below operational limits. Technicians confirmed sensor failures and planned corrective actions. All findings were recorded for future maintenance tracking and compliance.

Electrical system faults were also identified during the inspection process. Communication loss with the VCMU was reported multiple times. Moreover, CAN bus errors disrupted data flow between control modules and engines. These faults can cause unpredictable engine behavior and safety risks. Technicians recommended checking wire connections and replacing damaged couplers. Earth leakage was found in the master cabin WC control unit. Voltage readings were unstable due to incorrect wiring attempts. Control card testing and rewiring were advised to restore functionality. All electrical issues were documented and tagged for repair.

Hydraulic systems showed signs of wear and leakage during inspection. The IPS hydraulic oil distribution box had visible oil seepage. This was caused by degraded sealing surfaces and faulty o-rings. Technicians recommended replacing gaskets and resealing the mounting interface. Thermal imaging revealed abnormal heat zones on engine components. Vibration readings indicated imbalance in rotating machinery. These findings suggest the need for shaft alignment and bearing checks. A planned maintenance system was proposed for long-term reliability. The yacht was cleared for operation after implementing temporary safety measures.
