1.5.2.1 The structure,
equipment, fittings, arrangements and material (other than items in
respect of which a Cargo Ship Safety Construction Certificate, Cargo
Ship Safety Equipment Certificate and Cargo Ship Safety Radiotelegraphy
Certificate or Cargo Ship Safety Radiotelephony Certificate is issued)
of a gas carrier should be subjected to the following surveys:
-
.1 An initial survey before the ship is put in
service or before the International Certificate of Fitness for the Carriage of
Liquefied Gases in Bulk is issued for the first time, which should include a
complete examination of its structure, equipment, fittings, arrangements and
material in so far as the ship is covered by the Code. This survey should be such
as to ensure that the structure, equipment, fittings, arrangements and material
fully comply with the applicable provisions of the Code.
-
.2 A periodical survey at intervals specified by the
Administration, but not exceeding five years which should be such as to ensure
that the structure, equipment, fittings, arrangements and material comply with the
applicable provisions of the Code.
-
.3 A minimum of one intermediate survey during the
period of validity of the International Certificate of Fitness for the Carriage of
Liquefied Gases in Bulk. In cases where only one such intermediate survey is
carried out in any one certificate validity period, it should be held not before
six months prior to, not later than six months after, the half-way date of the
certificate's period of validity. Intermediate surveys should be such as to ensure
that the safety equipment, and other equipment, and associated pump and piping
systems comply with the applicable provisions of the Code and are in good working
order. Such surveys should be endorsed on the International Certificate of Fitness
for the Carriage of Liquefied Gases in Bulk.
-
.4 A mandatory annual survey within three months
before or after the anniversary date of the International Certificate of Fitness
for the Carriage of Liquefied Gases in Bulk which should include a general
examination to ensure the structure, equipment, fittings, arrangements and
materials remain in all respects satisfactory for the service for which the ship
is intended. Such a survey should be endorsed in the International Certificate of
Fitness for the Carriage of Liquefied Gases in Bulk.
-
.5 An additional survey, either general or partial
according to the circumstances, should be made when required after an
investigation prescribed in 1.5.3.3, or whenever any important repairs or renewals
are made. Such a survey should ensure that the necessary repairs or renewals have
been effectively made, that the material and workmanship of such repairs or
renewals are satisfactory; and that the ship is fit to proceed to sea without
danger to the ship or persons on board.
