other low melting metal construction that is not made equivalent to
steel, the following provisions should be satisfied:
.1 if the platform is cantilevered over the side
of the ship, after each fire on the ship or on the platform, the platform
should undergo a structural analysis to determine its suitability
for further use; and
.2 if the platform is located above the ship's
deckhouse or similar structure, the following conditions should be
.2.1 the deckhouse top and bulkheads under the
platform should have no openings;
.2.2 all windows under the platform should be
provided with steel shutters; and
.2.3 after each fire on the platform or in close
proximity, the platform should undergo a structural analysis to determine
its suitability for further use.
2.3 A helideck should be provided with both a
main and an emergency means of escape and access for fire fighting
and rescue personnel; these should be located as far apart from each
other as is practicable and preferably on opposite sides of the helideck.
3.1 In close proximity to the helideck the following
fire-fighting appliances should be provided and stored near the means
of access to that helideck:
.1 at least two dry powder extinguishers having
a total capacity of not less than 45 kilograms;
.2 carbon dioxide extinguishers of a total capacity
of not less than 18 kilograms or equivalent;
.3 a suitable foam application system consisting
of monitors or foam making branch pipes capable of delivering foam
to all parts of the helideck in all weather conditions in which helicopters
can operate. The system should be capable of delivering a discharge
rate as required in the following table for at least five minutes.
rate foam solution (litres/min)
||up to but
not including 15 m
||from 15 m up
to but not including 24 m
||from 24 m
up to but not including 35 m
The principal agent should meet the performance standards
of the International Civil Aviation Organization - Airport Services
Manual, Part 1 - Rescue and Firefighting, Chapter 8 - Extinguishing
Agent Characteristics, Paragraph 8.1.5 - Foam Specifications Table
8-1, Level 'B' foam, and be suitable for use with salt water;
.4 at least two nozzles of an approved dual-purpose
type (jet/spray) and hoses sufficient to reach any part of the helideck;
.5 in addition to those required by regulation
II-2/17 of the 1974 SOLAS Convention as amended, two sets of fireman's
.6 at feast the following equipment, stored in
a manner that provides for immediate use and protection from the elements:
- adjustable wrench;
- blanket (fire resistant);
- cutters, bolt 60 cm;
- hook, grab or salving;
- hacksaw, heavy duty complete with 6 spare blades;
- lifeline of 5 mm diameter x 15 m in length;
- pliers, side cutting;
- set of assorted screwdrivers; and
- harness knife complete with sheath.
3.2 Drainage facilities in way of helidecks should
be constructed of steel and lead directly overboard independent of
any other system and designed so that drainage does not fall on to
any part of the ship.
Helicopter Refuelling and
Hangar Facilities (where fitted)
4.1 A designated area should be provided for the
storage of fuel tanks which should be:
.1 as remote as is practicable from accommodation
spaces, escape routes and embarkation stations; and
.2 isolated from areas containing a source of
4.2 The fuel storage area should be provided with
arrangements whereby fuel spillage may be collected and drained to
a safe location.
4.3 Tanks and associated equipment should be protected
against physical damage and from a fire in an adjacent space or area.
4.4 Where portable fuel storage tanks are used,
special attention should be given to:
.1 design of the tank for its intended purpose;
.2 mounting and securing arrangements,
.3 electrical bonding; and
.4 inspection procedures.
4.5 Storage tank fuel pumps should be provided
with means which permit shutdown from a safe remote location in the
event of a fire. Where a gravity fed fuelling system is installed,
equivalent closing arrangements should be provided to isolate the
4.6 The fuel pumping unit should be connected
to one tank at a time. The piping between the tank and the pumping
unit should be of steel or equivalent material, as short as possible,
and protected against damage.
4.7 Electrical fuel pumping units and associated
control equipment should be of a type suitable for the location and
4.8 Fuel pumping units should incorporate a device
which will prevent over-pressurization of the delivery or filling
4.9 All equipment used in refuelling operations
should be electrically bonded.
4.10 Signs "NO SMOKING" should be displayed at
4.11 Hangar, refuelling and maintenance facilities
should be treated as category A machinery spaces with regard to structural
fire protection, fixed fire-extinguishing and detection system requirements.
4.12 Closed hangar facilities or closed spaces
containing refuelling installations should be provided with mechanical
ventilation as required for closed ro-ro cargo spaces of cargo ships
(Regulation II-2/53.2.3 of the 1974
SOLAS Convention). Ventilation fans should be of non-sparking type.
4.13 Electrical equipment and wiring in closed
hangars or closed spaces containing refuelling installations should
comply with the requirements of Regulation
11-2/53.2.4 of the 1974 SOLAS Convention.
Occasional and Emergency
Where helicopters land or conduct winching operations on
an occasional or emergency basis on ships without helidecks, fire-fighting
equipment fitted in accordance with chapter
II-2 of the 1974 SOLAS Convention, may be used. This equipment
should be made readily available in close proximity to the landing
or winching areas during helicopter operations.
Operations Manual and Fire-fighting
6.1 Each helicopter facility should have an operations
manual, including a description and a checklist of safety precautions,
procedures, and equipment requirements. This manual may be part of
the ship's emergency response procedures.
6.2 The procedures and precautions to be followed
during refuelling operations should be in accordance with recognized
safe practices and contained in the operations manual.
6.3 Fire-fighting personnel consisting of at least
two persons trained for rescue and fire-fighting duties and fire-fighting
equipment should be immediately available at all times when helicopter
operations are expected.
6.4 Fire-fighting personnel should be present
whenever refuelling is taking place. These fire-fighting personnel
should not be involved with refuelling activities.
6.5 Regular on-board refresher training should
be carried out and additional supplies of fire-fighting media should
be provided for training and testing of the equipment.
