Checklist for Cargo Changeover from dry bulk cargo to oil tanker

The following check-lists are of a general nature and each ship should use them as a guide when developing its own comprehensive check-lists. 

Dry Bulk Cargo to Oil 
  • Sweep holds clean and lift cargo remains out of hold for disposal.
  • Wash cargo remains off bulkheads with a high pressure water jet, stripping slowly to remove water, leaving solid residues.
  • Remove solid residues from the tank top and sumps, and prove that the stripping suction is clear.
  • Remove suction doors and attach securely to stowage positions.
  • Close off sounding pipes to sumps as required.
  • Remove blanks from main cargo suctions and stripping discharges to after hold.
  • Lower and secure heating coils in place, connect and prove tight, as necessary.
  • Remove requisite blanks from gauging system and render fully operational.
  • Wash all stripping lines thoroughly to remove solid residues. As far as possible, test stripping valves for tightness to ensure valve seats are not damaged by solid residues
  • .Open, clean and check all strainers in cargo systems.
  • Check and clean hatch cover sealing arrangements, trackways etc.
  • Check hatch cover sealing arrangements and closing devices.
  • Remove blanks from gas lines, as necessary.
  • Set venting system for next cargo.
  • Prove all valves and non-return valves in cargo system are operational.
  • Inert holds prior to loading. During inerting, prove tightness of hatch covers, tank cleaning covers, access hatches and all openings into cargo spaces.
