Port State Control is the process by which a nation exercises authority over foreign ships when
those ships are in waters subject to its jurisdiction. The right to do this is derived from both
domestic and international law. A nation may enact its own laws, imposing requirements on
foreign ships trading in its waters, and nations which are party to certain international conventions
are empowered to verify that ships of other nations operating in their waters comply with the
obligations set out in those conventions.
The stated purpose of Port State Control in its various forms is to identify and eliminate ships
which do not comply with internationally accepted standards as well as the domestic regulations
of the state concerned. When ships are not in substantial compliance, the relevant agency of the
inspecting state may impose controls to ensure that they are brought into compliance.
Recently, IMO adopted a resolution providing procedures for the uniform exercise of Port State
Control, and regional agreements have been adopted by individual countries within Europe,
the European Union, and various East Asian and Pacific nations. A number of North African
Mediterranean nations have recently expressed their intention to set up a separate regional
agreement in their own area of the world. In addition, some countries such as the United States of
America have adopted a unilateral approach to the subject, which nevertheless has the same aims.
Shipowners and operators should take measures to reduce the likelihood that their ships will
be subjected to intervention or detention, bearing in mind that increasingly efficient databases
will enable the maritime authorities who participate in the growing range of international
agreements, memoranda and conventions to exchange information. Being inspected by one state
and given a clean bill of health will not necessarily prevent further inspections being made by
another maritime authority – and, as information is exchanged between various organisations, noncompliant
ships will find it increasingly difficult to continue operations.
However, not all flag states are able
to check their ships on a continuous basis when they are away
from their own ports, so PSC provides a back-up for monitoring
the implementation of international and domestic shipping
regulations. Whilst Port State Control as a concept is not new,
the increasing number of inspections and the coordination and
exchange of data generated from them is a significant
development, as is the stated intention of governments and
maritime authorities who see it as an effective means of
monitoring and implementing international conventions.
It is the owner who is ultimately responsible for all compliance
with international and national obligations but it is incumbent
upon any state which allows the registration of ships under
its flag effectively to exercise jurisdiction and control in
administrative, technical and social matters. A flag state is
required to take such measures as are necessary to ensure
safety at sea with regard to construction, maintenance and
seaworthiness, manning, labour conditions, crew, training and
prevention of collisions of ships flying its flag.
Specifically, ART 94 of UNCLOS (United Nations
Convention on the Law of the Sea) imposes a duty upon flag
states to take any steps which may be necessary to secure
compliance with generally accepted international regulations,
procedures and practices. This obligation is repeated at Article
27 in relation to oil pollution. This is achieved in the main
by the flag state issuing safety certificates often via the
classification societies indicating compliance with the principal
international conventions. It is these certificates, together with
related manning, crew and environmental requirements, which
form the basis of Port State Control.
Historically one of a ship’s most important attributes is the
flag which it flies and trades under, but recent developments
have highlighted the weaknesses inherent in this system. Some
of these developments are as much matters of perception as
of reality, but in so far as their impact on the viability of the
international maritime regime is appreciable, the effect of
these perceptions should not be underestimated. They are:
INTERNATIONAL CONVENTIONS
While there is a growing web of international regulations,
its development is dependent upon consensus and
agreement. Consequently, it has sometimes been necessary
to proceed at the pace of the slowest, which leads to delay
in implementation. However, it is acknowledged that IMO
has achieved impressive and much speedier results in
recent years.
THE FLAG STATES
Some flag states are seen as not fulfilling their function of
ensuring that the owner complies with his obligations. In
particular, the growth of registers which have no capability
and even less intention of monitoring compliance has led to
considerable criticism.
THE CLASSIFICATION SOCIETIES
The work of the classification societies has been seen as too
easily undermined, although in recent years IACS have done
much to improve both perception and reality in this area.
All of this has led to the burgeoning development in Port
State Control, not as an alternative to “Flag State Control” but
as an additional means of compelling owners to comply with
international regulations.
REGIONAL DEVELOPMENT OF PORT STATE CONTROL
Port State Control as a concept is developing worldwide as a
means of dealing with the problem of substandard shipping.
However, it is important that its development is not viewed in
isolation, as it remains one of a series of positive steps which
are being taken to ensure that the shipowner trades his ships
in a safe and environmentally responsible manner.
The first regional Port State Control agreement, covering
Europe and the North Atlantic, was signed in 1982 and is
known as the Paris Memorandum of Understanding (Paris
MOU). The Latin American Agreement (Acuerdo de Viña del
Mar) was signed in 1992; the Asia Pacific Memorandum of
Understanding (Tokyo MOU) was signed in 1993.
The Caribbean MOU and the Mediterranean MOU are in the
early states of implementation, the latter being signed in July
1997. The Port State Control Committee of the Caribbean
MOU, the body charged with implementing the administrative
framework necessary to give effect to the agreement, is
currently working on the programme needed to collate
information, establish a database and technical co-operation
programme, as well as train the surveyors and inspectors of
the countries involved. The Mediterranean MOU allows for an
interim establishment period of two years and the first session
of its Port State Control Committee has been scheduled for the
end of February 1998.
The Indian Government also announced plans to
lead a scheme for the Indian Ocean area.
It would appear that the accepted view is that Port State
Control works most effectively if implemented on a regional
basis. However, there are examples of nations that are not
signatories to a regional agreement but who nevertheless
pursue the same aims. For example, the USA exercises its Port
State Control authority through the US Coast Guard’s longstanding
foreign ship boarding programme, which is now
referred to as the Port State Control Programme.
The three “mature” regional
agreements for port state inspection are namely– the Paris MOU, the Tokyo MOU and the Latin
American Agreement – and, given the importance of the USA
as a trading nation and that it often leads the world by
example – an outline of the key provisions of the Port State
Control programme implemented by the US Coast Guard.
It is clear that Port State Control will continue to be
strengthened in existing areas and expanded into new ones.
