We have been contacted by several members requesting a further clarification on the definition of the Category of single hull oil tankers scheduled for phase-out, especially tankers between 20,000 and 30,000 dwt that could be seen as Category 2 oil tankers.

The amended Regulation 13G defines Category 2 ship as follows:

“Category 2 oil tanker” means an oil tanker of 20,000 tons deadweight and above carrying crude oil, fuel oil, heavy diesel oil or lubricating oil as cargo, and of 30,000 tons deadweight and above carrying oil other than the above, which complies with the requirements for new oil tankers as defined in regulation 1(26) of this Annex;

The clarification requested is as follows:

A 29,000 dwt new 1(26) product tanker carrying DPP (fuel, heavy diesel, or lube oils) would not be subject to phase-out under current 13G, but after the amendments come into force (i.e. 1 September 2002) she would be phased out as a Category 2 oil tanker in accordance with the new scheme. In this instance, she did not need to meet Protected Location PL/SBT requirements under Regulation 13E as she was less than 30,000 dwt, but is still a new 1(26) tanker and therefore a Category 2 oil tanker provided she continues to not carry any crude oil. If she carries crude then, she is a Category 1 tanker. If she carries only CPP (oils other than crude and DPP) then she is a Cat.3.

In conclusion these will be the categories for an oil tanker between 20,000 and 30,000 dwt built under regulation 1(26) – new tankers as defined in the 1978 Protocol to MARPOL – under the amended Regulation 13G:

  • Category 1 – if carries crude oil
  • Category 2 – if carries DPP
  • Category 3 – if carries CPP

The clarification is intended to highlight that these ships do not need PL/SBTs in order to qualify as Category 2 oil tanker even when transporting DPPs.
