Introduction
1 The Marine Environment Protection Committee (the Committee), at its sixty-fifth
session, adopted, by resolution MEPC.240(65), the 2013 Amendments to the Revised guidelines and
specifications for oil discharge monitoring and control systems for oil tankers
(resolution MEPC.108(49)), which contain, inter alia, the revised
form of certificate of type approval for oil content meters intended for monitoring the
discharge of oil-contaminated water from the cargo tank areas of oil tankers.
2 This guidance advises on the issuing of the revised certificate of type approval for
oil content meters.
Guidance
3 When the oil content meter (OCM) has been approved in accordance with resolution MEPC.108(49) before 17 May 2013, the Form of Type Approval
Certificate (TAC), as provided in resolution MEPC.108(49), may be used:
-
.1 for OCMs installed on ships not carrying biofuel blends; or
-
.2 for OCMs installed on ships carrying biofuel blends, until 1 January 2016 (on
the condition that the tank residues and washings are pumped ashore).
4 For all ships carrying biofuel blends on or after 1 January 2016, the OCM should have a
TAC, as modified by resolution MEPC.240(65).
5 When the OCM has been tested and submitted for approval (or re-approval in the case of
OCMs that have undergone modifications but were originally approved in accordance with
resolution MEPC.108(49)) on or after 17 May 2013, regardless of whether the
OCM is intended for monitoring biofuel blends, the Form of the TAC should be amended in
accordance with resolution MEPC.240(65).
