Annex - 2011 Guidelines for the carriage of blends
of petroleum oil and biofuels, as
amended
1 - Application
1.1 These guidelines apply to ships when
carrying in bulk blends of petroleum
oil and biofuels subject to Annex I and Annex II
of MARPOL, respectively.
2 - Scope
2.1 These Guidelines have been developed to
clarify how biofuels subject to
Annex II of MARPOL, when blended with petroleum oils,
subject to Annex I of MARPOL, can be shipped in bulk.
3 - Definitions
For the
purpose of these guidelines:
3.1
Biofuels are ethyl alcohol,
fatty acid methyl esters (FAME), vegetable oils
(triglycerides) and alkanes (C10-C26), linear and branched
with a flashpoint of either 60°C or less or more than 60°C,
as identified in chapters 17 and 18 of the IBC Code or the
MEPC.2/Circular/tripartite agreements. Following the
distribution of these guidelines, further biofuels identified as falling
under the scope of the guidelines, will be recorded in annex
11 of the MEPC.2/Circular which deals with biofuel/petroleum oil blends.
3.2
Biofuel blends are mixtures
resulting from the blending of those products identified
in paragraph 3.1 above with
a petroleum oil.
4 - Carriage of biofuel
blends
The carriage
provision for biofuel blends is based on the volumetric
composition of the blends as follows:
4.1
Biofuel blends containing 75
per cent or more of
petroleum oil
4.1.1 When containing 75 per cent or more of petroleum
oil, the biofuel blend is
subject to Annex I of MARPOL.
4.1.2 When carrying such biofuel blends, Oil Discharge
Monitoring Equipment (ODME – see resolution
MEPC.108(49)) shall be in compliance with regulation 31
of Annex I of MARPOL and should be approved for the
mixture being transported.
4.1.3 Until 1 January 2016 biofuel blends may be carried
when the ship's ODME is not in compliance with paragraph
4.1.2 above provided that tank residues and all tank
washings are pumped ashore.
4.1.4 When considering the deck
fire-fighting system requirements of SOLAS chapter II-2,
regulations 1.6.1 and 1.6.2, when carrying biofuel
blends containing more than 5 per
cent of ethyl alcohol then alcohol resistant
foams should be used.
4.2
Biofuel blends containing more
than 1 per cent but less than
75% of petroleum oil
4.2.1 When containing more
than 1 per cent but less
than 75% of petroleum oil, the biofuel blends are subject to Annex II of
MARPOL and should be carried under the following
conditions:

4.2.2 With respect to new
biofuels identified as
falling under the scope of these guidelines, carriage
requirements for specific biofuel/petroleum oil blends to be shipped
as MARPOL Annex II cargoes will be incorporated into
List 1 of the MEPC.2/Circular, as appropriate.
4.3
Biofuel blends containing 1
per cent or less petroleum
oil
4.3.1 When containing 1 per cent or less of petroleum
oil, the biofuel blends are
subject to Annex II of MARPOL.
5 - Blending of petroleum oil and biofuel on board
5.1 Blending on board describes
the mixing of two products resulting in one single product
(a blended mixture) and reflects only physical mixing as
distinct from any chemical processing. Such mixing
operations should only be undertaken whilst the ship is
within port limits.
5.2 The physical blending on board
of petroleum oil and biofuels during a sea voyage to create
new products is prohibited as indicated in MSC-MEPC.2/Circ.8
– Prohibition of blending MARPOL cargoes on board during the
sea voyage.
6 - Certification requirements
6.1 The certification for the
biofuel blend to be shipped
should be in compliance with Annex I or Annex II of MARPOL,
as appropriate.
