vessel is subject to a continuous survey cycle, in which every part of the vessel would be surveyed within a
five-year cycle (subject to any grace period granted) according to an agreed schedule on a staggered basis.
Vessels are required to be dry-docked, usually twice in five years, for survey of the underwater parts and
for repairs related to the inspections.
If any defects are found by the classification surveyor during any survey of the vessel, he may require an
immediate repair to be carried out. If, however, the surveyor considers it safe for the vessel to continue in
service without an immediate repair, the surveyor will issue a condition of class, which will require the defect
to be rectified by the ship owner within prescribed time limits. Any conditions of class must be repaired at the
due time set out by the surveyor(s).
All insurance underwriters make it a condition for insurance coverage that a vessel be certified as “in
class” by a classification society. In addition, charterers will impose as a condition of the charter contract, that
the vessel under charter must be duly certified by a classification society.
