Revision of Singapore bunkering procedures CP 60

Recently an amendment was made to the Singapore bunkering procedures, CP60, regarding custody transfer sampling. This amendment brings the Singapore standard in line with the international standard, ISO 8217, which specifies fuel standards and states that the properties of fuels are determined at the time and place of custody transfer. The place of custody transfer is the point where the bunker fuel passes the rail of the receiving vessel. Bunker samples should be taken at the custody transfer point, i.e. at the bunker manifold flange of the receiving vessel.

INTERTANKO welcomes this development, which has been one of the long-standing issues on INTERTANKO’s Bunker Sub-committee's agenda. However, there still remain other necessary amendments to CP 60, one of which relates to the current practice of ‘air blowing’ during the bunker delivery. This aspect of the CP 60 requirements needs amending and MPA has agreed to discuss this at their next Technical Committee meeting. The MPA is investigating reported shortfalls in bunker deliveries, and encourages INTERTANKO members to come forward with information on their experiences regarding bunkering problems either with quality or quantity. In response to a request from the Technical Committee for Bunkering in Singapore charged with the revisions of CP60, of which INTERTANKO is a member, INTERTANKO proposed to amend Clause 18 of CP60 to a simple one-line statement that blending on a barge is not permitted whatever the reasoning.


Revision of ISO 8217 - fuel bunkering standard

This work and attendance at the Working Group meetings every six months are undertaken simultaneously with attendance at the CIMAC revision of their Recommendations for heavy fuels for large diesel engines. The revision of the Bunker Standard ISO 8217 has reached the DIS (final draft for consultation) stage and is expected to be a published revised standard 2004. Work will then commence on a further revision to take into account regulatory requirements and further modifications reflecting the trend towards an increased quality of marine fuels.

During this further work, issues such as catalytic fines and their acceptable levels will be addressed and reviewed. For assistance with NOx control (Annex VI), the issue of Asphaltene/PAH (polycyclic aromatic hydrocarbon) and an appropriate parameter/level has also been raised for consideration. This current revised standard has corrected and modified parameters within the 1996 standard. As examples, amendments to the water content parameter have reduced the allowed water content from 1.0% to 0.5% and have also introduced a ban on the blending of Used Automotive Lube Oil (ULO) into delivered Marine HFO.  Due to the action of ULO on the purification process, this change to the standard should allow greater efficiency in the purification of fuel oils to be used onboard ships thereby reducing engine wear from unwanted species within the fuel oil delivered.


INTERTANKO’s objectives on these two activities are to represent members’ interests in protecting against malpractice in bunker deliveries. As a result of these activities, it is reported that Singapore's new CP 60, its new Quality Chain for bunker delivery and the recently adopted licensing procedure for bunker deliverers have significantly improved the situation. Reports indicate that the number of arbitrations relating to bunker deliveries is reducing and, when problems do occur, these are solved quickly because of the evidence kept onboard the ship and of the port authority’s control.

The INTERTANKO Bunker Sub-Committee coordinates a number of issues already covered under various INTERTANKO issues. In addition, the Committee is working on two issues of importance for INTERTANKO’s members.
