Tank truck to marine vessel - Oil transfer
11. Operating Procedures

Table of Content

Before carrying out any oil transfer, adequate preparation is required to ensure that the following safeguards are in place:

11.1 Before Transfer

Before carrying out any oil transfer check the following 6 areas:

  1. The tank truck must be safely and securely located to prevent damage from the truck to its surroundings.


    Ensure the location is acceptable in accordance with the requirements in the "Oil Transfer Locations" section of this document.

    • Set the parking brake and/or chock the wheels
    • The truck engine must be shut off while connecting or disconnecting hoses
  2. The vessel must be suitably located, secured and fitted to safely receive the delivery.
  3. A spill contingency plan must be in place to enable a quick, effective and sustained response to any emergency at that specific location.
  4. The fuel transfer safety checklist must be completed with a copy retained by the driver and a copy left with the vessel.
  5. The driver and marine representative must agree on the amount to be transferred, making allowance for:
    • Thermal expansion: the tank should not be filled above 95% capacity,
    • Sufficient additional tank capacity to accept the hose's line fill after the pumping is complete.
  6. Communications should be ensured between the following:
    • The truck and vessel, to ensure that both parties are in constant, clear communication throughout the oil transfer operation
    • The transfer location and the head office or other outside resource to ensure that, in the event of an incident, an appropriate response can be initiated without delay

Oil transfer operations are not to take place until all communication systems have been confirmed for proper operation.

At the first signs of an electrical storm, the operation must be shut down.

11.2 Fuel Transfer Safety Checklist

The transferring Company should have a checklist appropriate for the operation being carried out. This safety checklist must be filled out and kept available during the transfer operation.

The purpose of the checklist is to ensure that both parties, the driver and marine representative, have had a "meeting of minds" and understand the particulars of the transfer operation. It also provides a double check that required precautions are in place.

See "Appendix A: Fuel Safety Transfer Checklist", for a sample checklist used in the Port of Vancouver and other jurisdictions. It provides a model for Company-specific checklists. On this checklist the driver is considered to be the "facility".

By filling out and signing the checklist the driver and marine representative agree that their responsibilities have been met.

Additional information on Company-specific checklists might include:


As important as the checklist is, it cannot take the place of a thorough understanding of this document and the requirements of the operation being carried out.

11.3 Starting Transfer

Proper and careful preparation are required for a safe transfer operation. Do not begin the transfer until all of the proper steps have been taken.

11.4 Finishing Transfer

Most spills during transfer occur when finishing the filling process, for the obvious reason that this is when overfills can occur. Constant vigilance is required.

11.5 Draining Hoses

Care must be taken when draining hoses to prevent any spillage or drips from causing pollution or slipping hazards.
