Background
1 Article 3 of the International Convention for the Control and Management of Ships'
Ballast Water and Sediments, 2004 (the Convention), identifies the ships to which the
Convention applies and does not apply. Article 3.1 of the Convention includes all ships
entitled to fly the flag of a Party, and ships not entitled to fly the flag of a Party,
but which operate under the authority of a Party, except as provided otherwise in the
Convention.
2 Articles 3.2(b) to 3.2(d) set out conditions under which the Convention does not apply
to a ship of a Party that operates only in waters under the jurisdiction of that Party,
or another Party, or in such waters and on the high seas, respectively. Such ships
should be subject to the appropriate national policies, strategies or programmes for
Ballast Water Management of the Party or Parties established pursuant to article
4.2.
3 Ships operating pursuant to articles 3.2(b) to 3.2(d) that cease to operate
exclusively in the relevant waters lose their exclusion from the Convention, which then
fully applies to them on an ongoing basis, except as provided in this Guidance.
Purpose
4 The purpose of this Guidance is to provide advice on entry or re-entry into exclusive
operation pursuant to articles 3.2(b) to 3.2(d), which will assist Administrations with
respect to a number of situations, including:
-
.1 ships (e.g. mobile offshore units) that may be assigned to extended operations
in waters under the jurisdiction of a single Party following an international
voyage or voyages; and
-
.2 ships which operate usually within waters under their jurisdiction, but which
may occasionally need to leave these waters and return (e.g. to visit a dry-dock).
Such ships may consider that regulations A-4, B-3.6 and B-3.7 provide options that
are particularly attractive for short-term compliance with the Convention.
5 The provisions of this Guidance that pertain to entry into exclusive operation do not
apply to a ship that is launched into the waters of the Party within which it is
constructed until it requires an International Ballast Water Management Certificate.
Guidance
6 Subject to the conditions of articles 3.2(b) to 3.2(d) concerning the environment,
human health, property and resources, the application of the Convention to a ship of a
Party may cease:
-
.1 pursuant to article 3.2(b), if the ship enters or re-enters into exclusive
operation in waters under the jurisdiction of that Party;
-
.2 pursuant to article 3.2(c), if the ship enters or re-enters into exclusive
operation in waters under the jurisdiction of another Party, subject to the
authorization of the latter Party for such cessation; and
-
.3 pursuant to article 3.2(d), if the ship enters or re-enters into exclusive
operation in waters under the jurisdiction of one Party and on the high seas,
unless the ship has not been granted an authorization pursuant to article
3.2(c).
7 Before ceasing application of the Convention to a ship referenced in paragraph 4, the
Administration (and authorizing Party, if applicable) should verify that the ship:
-
.1 is in compliance with the Convention and holds a valid International Ballast
Water Management Certificate, if required to do so;
-
.2 has fully discharged all ballast water, including any residual ballast water,
and has completely removed and disposed of all sediments, in accordance with the
Convention and the ship's approved Ballast Water Management plan;
-
.3 has a procedure in its approved Ballast Water Management plan for thoroughly
cleaning its ballast water tanks, piping and equipment that is satisfactory to the
Administration (and authorizing Party, if applicable); and
-
.4 has carried out the procedure described in subparagraph 7.3 above, to the
satisfaction of the Administration (and authorizing Party, if applicable).
8 Upon cessation of the application of the Convention to a ship, any International
Ballast Water Management Certificate issued to the ship should be withdrawn.
9 A ship referred to in paragraph 3 on a single voyage may be granted an exemption under
regulation A-4 on the condition that the ship performs ballast water exchange in
accordance with regulations B-4 and D-1 and an approved Ballast Water Management plan.
The requirements of regulation A-4.1.4 should be addressed to the satisfaction of the
countries of origin and destination of the ship.
