Answer
The United States Coast Guard (USCG) enforces port state regulations rigorously through its Qualship 21 and targeted PSC matrix. A USCG detention can severely disrupt ship operations and owner reputations.
Key Engineering Preparations Checklist
Oily Water Separator (OWS) & 15-ppm Monitor:
Test the 15-ppm alarm, automatic 3-way valve recirculation loop, and look for any signs of illegal bypasses ("magic pipes"). The USCG frequently unscrews pipe sections around the OWS to check for internal carbon/oil deposits.
Verify the ORB Part I records match the electronic data logger on the OWS perfectly. No missing entries, no layout inconsistencies, and all corrections strictly initialed.
Emergency Power and Lighting Systems:
Test the Emergency Generator for automatic starting and power grid connection upon a simulation of main switchboard black-out. Ensure it starts within 45 seconds.
Confirm the emergency air compressor functions perfectly and can charge the emergency air bottle.
Check all emergency lights in the machinery spaces, steering gear room, and escape trunks.
Fire Safety and Quick-Closing Valves:
Test the Emergency Fire Pump. Ensure it can deliver the required water pressure to at least two hoses simultaneously at the highest points of the ship.
Perform physical checks on all fuel tank quick-closing valves. Ensure wires, pneumatic actuators, and pull-stations are fully free, lubricated, and operational.
Verify that the engine room fire dampers seal completely. The USCG inspector will frequently check the external integrity of fire flaps.
Steering Gear Performance:
Conduct a full steering gear drill, testing the main and auxiliary systems from all steering stations (bridge, trickle wheel, local).
Verify the 10-minute emergency power supply loop works for the steering gear alarms and indicators, and confirm the rudder moves from 35∘ on one side to 30∘ on the other within 28 seconds.
No Spills/Leaks Policy: Clean up any oil pools in the purifier room or main engine tank tops. Put dry-mats down, trace and eliminate active fuel/lube drips, and ensure the engine room looks well-maintained.
