C1 GUIDELINES FOR TRANSFER OPERATIONS 

A stowage plan must be produced showing cargo distribution on the tankship and covering the following:

  Information on each product (see Part III)
  Quantity of each product
  Line(s) to be used
  Operating pressure and maximum allowable pressure
  Temperature limits
  The initial, maximum and top off flow rates, having regard to:

  • the nature of the cargo
  • the arrangements and capacity of the ship's cargo lines, shore pipelines and tanks
  • the maximum allowable pressure and flow rate in the deliverer/receiver hoses or arms
  • limitations because of electrostatic properties, use of automatic shut-down valves or any other limitations which may affect flow rates

There must be an agreement on the timing and sequence in which the ship's tank(s) are to be filled or discharged, taking account of:

  Deliverer/Receiver tank change over
  Avoidance of contamination of cargo
  Pipeline clearing for discharge
  Crude oil washing, if employed, or other tank cleaning method
  Trim and freeboard of the tankship
  Hull stresses which will not be exceeded
  Ballasting/Deballasting operations

Also, taking account of the following:

  Inspection of ship's cargo tanks before loading or discharging
  Venting requirements  
  Bunkering or storing operations
