Meaning of the term "Periodical Survey"
1 In SOLAS regulations XII/3, XII/7 and XII/11, the term "periodical survey"
has been used to refer to the dates by which the requirements under
these regulations are to be complied with. Since the requirements
under SOLAS chapter XII mainly deal
with the hull structure, it is necessary that the above-mentioned
threshold dates are associated with the examination of the outside
of the ship's bottom. Therefore, the term "periodical survey" referred
to in SOLAS chapter XII is linked
to the surveys which are associated with an examination of the outside
of the ship's bottom i.e. the intermediate surveys and renewal surveys
for the Cargo Ship Safety Construction Certificate, or the Cargo Ship
Safety Certificate, as mentioned in SOLAS regulations I/10 and I/12,
as modified by the 1988 SOLAS Protocol.
2 Considering that the terms "intermediate survey"
or "renewal survey" have been used in all IMO instruments, instead
of the term "periodical survey", after the 1988 SOLAS Protocol entered
into force, Administrations may note that the meaning of the term
"periodical survey" in the context of SOLAS regulations XII/3, XII/7 and XII/11 is the same as "renewal survey"
or "intermediate survey" of a ship, as referred to in SOLAS regulation I/10, as modified by the 1988
SOLAS Protocol.
