(ClassNK)

6. Introduction to ClassNK
Nippon Kaiji Kyokai, known as ClassNK or NK,
is a ship classification society.
It is what is known under Japanese law as a public
service foundation and in its Act of Endowment, its
ultimate goal is expressed as: "to contribute to the
development of maritime service for the protection of
human life and property at sea". Environmental
protection has also become an increasingly major
concern.

19. Annual Surveys
1 The purpose of an Annual Survey is to confirm
that the general condition of the hull is
maintained at a satisfactory level.
2 Generally as the ship ages, ballast tanks are
required to be subjected to more extensive
overall and close-up surveys at Annual
Surveys.

20. Intermediate Surveys
1 The Intermediate Survey may be held at or
between the second or third Annual Survey in
each five year Special Survey cycle. Those
items, which are additional to the requirements
of the Annual Surveys, may be surveyed either
at or between the 2nd and 3rd Annual Survey.
The intermediate survey contains requirements
for extended overall and close-up surveys
including thickness measurements of cargo and
ballast tanks.

21. Special Surveys
1 The Special Surveys are carried out at five-year intervals
for the purpose of establishing the condition of the
structure to confirm that the structural integrity is
satisfactory in accordance with the Classification
Requirements, and will remain fit for its intended purpose
for another five-year period, subject to proper
maintenance and operation of the ship and to periodical
surveys carried out at the due dates.
2 The Special Survey concentrates on close-up surveys in
association with thickness measurements and is aimed
at detecting fractures, buckling, corrosion and other
types of structural deterioration.
3 Thickness measurements are to be carried out upon
agreement with the Classification Society concerned in
conjunction with the Special Survey.

22. Drydocking (Bottom) Surveys
The objective of docking the ship periodically
is to inspect the portion of the hull beneath
the water-line which those parts of the hull
under the water-line are always immersed in
water; therefore, the condition of damage in
the event of the ship stranding /
grounding/damages cannot be observed.
