This publication describes the methods for retaining oil residues on board, to help ship staff comply with the oil discharge limits in MARPOL Annex 1. This book assists owners and operators of oil tankers, oil tanker crew, governments, port authorities, terminal operators, cargo shippers and cargo receivers.
The
clean
seas
programme
was
introduced
by
the
shipping
industry
to
restrict
the
oiperational
discharge
of
oil
in
to
the
sea
by
the
retention
of
oil
residues
onboard.
The
Guide,
which
describes
the
procedures
used
to
retain
oil
residues
onboard,
is
intended
to
help
shipboard
personnel
comply
with
the
oil
discharge
limitations
that
are
contained
in
Annex
1
of
MARPOL.
The
1973
MARPOL
convention,
as
amended
by
its
1978
Protocol,
is
the
international
instrument
controlling
pollution
from
ships.
Annex
1
of
the
convention,
which
contains
regulations
for
the
prevention
of
pollution
by
oil,
came
into
effect
in
October
1983.
Effective
retention
of
oil
onboard
(R.O.B.)
requires
a
thorough
understanding
of
the
procedure
and
the
techniques
required.
OCIMF/ICS
strongly
recommend
this
guide.
