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, itsultimate 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.

Annual Surveys

1 The purpose of an Annual Survey is to confirmthat the general condition of the hull is

maintained at a satisfactory level.

2 Generally as the ship ages, ballast tanks arerequired to be subjected to more extensive

overall and close-up surveys at Annual

Surveys.


20/109

Intermediate Surveys

1 The Intermediate Survey may be held at orbetween 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 surveysincluding thickness measurements of cargo and

ballast tanks.


21/109

Special Surveys

1 The Special Surveys are carried out at five-year intervals

for the purpose of establishing the condition of thestructure to confirm that the structural integrity issatisfactory in accordance with the ClassificationRequirements, and will remain fit for its intended purposefor another five-year period, subject to propermaintenance and operation of the ship and to periodicalsurveys carried out at the due dates.

2 The Special Survey concentrates on close-up surveys inassociation with thickness measurements and is aimedat detecting fractures, buckling, corrosion and othertypes of structural deterioration.

3 Thickness measurements are to be carried out uponagreement with the Classification Society concerned inconjunction with the Special Survey.
