to the provisions of paragraphs 4 and 5 of regulation 3 of this Annex, oil tankers of 150 gross tonnage
and above shall be equipped with an oil discharge monitoring and control
system approved by the Administration.
2 In considering
the design of the oil content meter to be incorporated in the system,
the Administration shall have regard to the specification recommended
by the Organization. footnote The system
shall be fitted with a recording device to provide a continuous record
of the discharge in litres per nautical mile and total quantity discharged,
or the oil content and rate of discharge. This record shall be identifiable
as to time and date and shall be kept for at least three years. The
oil discharge monitoring and control system shall come into operation
when there is any discharge of effluent into the sea and shall be
such as will ensure that any discharge of oily mixture is automatically
stopped when the instantaneous rate of discharge of oil exceeds that
permitted by regulation 34 of
this Annex. Any failure of this monitoring and control system shall
stop the discharge. In the event of failure of the oil discharge monitoring
and control system a manually operated alternative method may be used,
but the defective unit shall be made operable as soon as possible.
Subject to allowance by the port State authority a tanker with a defective
oil discharge monitoring and control system may undertake one ballast
voyage before proceeding to a repair port.
3 The oil
discharge monitoring and control system shall be designed and installed
in compliance with the guidelines and specifications for oil discharge
monitoring and control system for oil tankers developed by the Organization footnote. Administrations may accept such specific
arrangements as detailed in the Guidelines and Specifications.

manual approved by the Administration. They shall cover manual as
well as automatic operations and shall be intended to ensure that
at no time shall oil be discharged except in compliance with the conditions
specified in regulation 34 of
