Bunkering Checklist IAPH /SGMF Safety achieved by:

Confirming that a competent person has satisfactorily completed the checklist.

Sighting appropriate records.

By joint inspection, where deemed appropriate.

Abbreviation Used • A („Agreement‟). This indicates that the referenced

consideration should be addressed by an agreement or procedure that should be identified in the „Remarks‟ column of the Check List or communicated in some other mutually acceptable form.

• R („Re-check‟). This indicates items to be re-checked at appropriate intervals, as agreed between both parties and stated in the declaration.

• The joint declaration should not be signed until all parties have checked and accepted their assigned responsibilities and accountabilities.

Bunkering Checklist Contents 1. Bunkers to be Transferred • A joint agreement on the quantity and grades of bunkers to

be transferred, together with agreed • transfer rates and the maximum line back pressures.

2. Bunker Tanks to be Loaded • An identification of the tanks to be loaded with the aim of

ensuring that there is sufficient space to safely accommodate the bunkers to be transferred. Space is provided to record the each tank maximum filling capacity and the available volume.

Bunkering Checklist Contents 3. Checks by Barge Prior to Berthing • This section provides the checks to be carried out

before the barge goes alongside the ship.

4. Checks Prior to Transfer • This section provides the checks to be jointly

undertaken before transfer activities commence. • The numbers in brackets after each of the questions

in Sections 3 and 4 relate to the • guidance notes for completing the Ship/Shore Safety

Check List in Section 26.4, which • should be referred to for additional information

Key Points of Checklist. • Is there a clear Safety Management System in place ? • Are all roles and responsibilities clear to all parties ? • Are all parties involved in the bunkering operation aware of the operational procedures ? • Is there a communication system agreed? • Have Hazardous, safety and security zones been defined ? • Are the ESD systems compatible ? • Are the mooring arrangements acceptable ? • Is the transfer system compatible with the receiving manifold ?

Training

• The STCW amendments adopted as part of the 2015 amendments to STCW, however, they will be worded so that they will come into force when the IGF Code comes into force (~2017).

IGF CODE

IGC code does not cover LNG as fuel, the IMO’s Marine Safety Committee has proposed the development of a code for non-LNG carriers using LNG as a fuel. This new “International Code of Safety for Ships using Gases or other Low Flashpoint Fuels” (IGF Code) approved in June 2015. It is planned to come into force in 2016/2017
