ENSIS 5000 Heavy Lift Crane Vessel

Conduct ultrasonic thickness testing (UTT) and magnetic particle inspection of main boom, pedestal, and frame welds for internal cracks, fatigue, and material degradation. Verify deck connection welds and structural attachment points for corrosion and stress fractures.

Perform stationary proof load test at 110-125% of rated Safe Working Load (SWL) to verify structural integrity. Conduct operational test cycles including full lifting, swinging (360 degrees), and lowering movements under simulated working conditions. Document load test results and maintain certification records per SOLAS II-1/3-13 (effective January 1, 2026).

Inspect all wire rope for cracks, gouges, nicks, corrosion, distortions, and strand breakage. Test hoist brake effectiveness, verify load chain integrity (cracks, corrosion, wear), and inspect hooks for deformation or cracks. Ensure sheaves and pulleys rotate freely without binding. Check all limit switches, emergency stops, and load indicators for proper function.

Inspect all hydraulic/pneumatic lines for deterioration, leakage, and proper routing at flex points. Verify cylinder rod integrity for scoring, pitting, and seal leaks. Test all hydraulic functions for smooth operation without drift or erratic behavior. Check hydraulic fluid color and viscosity (must be replaced at manufacturer intervals). Verify pressure relief valves and safety systems function correctly.

Inspect brake wheels for oil saturation and surface wear (replacement required if wear exceeds 1/4 of original thickness). Measure brake pad thickness (minimum 5mm required) and verify synchronization across brake systems. Test all control systems including pendant controls, limit switches, and emergency stop functionality. Verify brake holding capacity under load.
