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.

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.
