7.2.1 While
the ship is in dry dock, all openings to the sea in the machinery
spaces, together with the valves, cocks and the fastenings with which
these are connected to the hull, are to be examined.
7.2.2 All
shafts (except screwshafts and tube shafts, for which special arrangements
are detailed in Vol 1, Pt 1, Ch 3, 13 Screwshafts, tube shafts and propellers),
thrust block and all bearings are to be examined. The lower halves
of bearings need not be exposed if alignment and wear are found to
be acceptable.
7.2.3 An examination
is to be made of all reduction gears complete with all wheels, pinions,
shafts, bearings and gear teeth, thrust bearings and incorporated
brake and clutch arrangements where fitted.
7.2.4 The
following auxiliaries and components are also to be examined:
-
Auxiliary engines, auxiliary air compressors with their intercoolers,
filters and/or oil separators and safety devices, and all pumps and components
used for Mobility or Ship Type systems.
-
Steering machinery.
-
Windlass and associated
driving equipment, where fitted.
-
The holding down
bolts, chocks of main and auxiliary engines, gearcases, thrust blocks
and intermediate shaft bearings.
-
Evaporators (other
than those of vacuum type) and their safety valves, which should be
seen in operation under steam.
7.2.5 All Ancillary systems are to be examined to ensure that there have been no modifications
to the system that change the category, and no degradation that impacts on other systems
or basic conditions on board.
7.2.6 All air receivers for Mobility or Ship Type systems, together with their
mountings, valves and safety devices, are to be cleaned internally and examined
internally and externally. If internal examination of the air receivers is not
practicable, they are to be tested hydraulically to 1,3 times the working pressure.
7.2.7 The valves, cocks and strainers of the bilge and salvage system including
bilge injection, are to be opened up as considered necessary by the Surveyor and
together with pipes, are to be examined and tested under working conditions. The fuel
oil, feed, lubricating oil and cooling water systems, also the ballast connections
together with all pressure filters, heaters and coolers used for Mobility or Ship Type
systems, are to be opened up and examined or tested, as considered necessary by the
Surveyor. All safety devices for the foregoing items are to be examined.
7.2.8 Fuel
tanks which do not form part of the ship’s structure are to
be examined, and if considered necessary by the Surveyor, they are
to be tested to the pressure specified for new tanks. The tanks need
not be examined internally at the first survey if they are found satisfactory
on external inspection. The mountings, fittings and remote controls
of all fuel oil tanks are to be examined, so far as is practicable.
7.2.9 Where remote and/or automatic controls are fitted for Mobility or Ship Type
System, they are to be tested to demonstrate that they are in good working order.
7.2.10 In addition to the above, detailed requirements for steam and gas turbines,
engines, electrical installations and boilers are given in Vol 1, Pt 1, Ch 3, 8 Turbines – Detailed requirements,Vol 1, Pt 1, Ch 3, 9 Reciprocating internal combustion engines – Detailed requirements, Vol 1, Pt 1, Ch 3, 10 Electrical equipment and Vol 1, Pt 1, Ch 3, 11 Boilers respectively. In certain instances, upon application by the Owner
or where indicated by the maker’s servicing recommendations, LR will give consideration
to the circumstances where deviation from these detailed requirements is warranted,
taking account of design, appropriate indicating equipment (e.g. vibration indicators)
and operational records.
