13.9.2 Segregation of Purifiers for Heated Fuel Oil (1 July 2002)
Fuel oil purifiers for heated oil are to be placed in a separate room or rooms, enclosed by steel
bulkheads extending from deck to deck and provided with self-closing doors. In addition, the
room is to be provided with the following:
i)
Independent mechanical ventilation or ventilation arrangement that can be isolated
from the machinery space ventilation, of the suction type.
ii)
Fire detection system.
iii)
Fixed fire-extinguishing system capable of activation from outside the room. The
extinguishing system is to be dedicated to the room but may be a part of the fixed fire
extinguishing system for the machinery space.
However, for the protection of purifiers on cargo vessels of 2000 gross tonnage and
above located within a machinery space of category A above 500 m3 (17,657 ft3) in
volume, the above referenced fixed dedicated system is to be a fixed water-based or
equivalent, local application fire-extinguishing system complying with the provisions
of 4-7-2/1.11.2. The system is to be capable of activation from outside the purifier
room. In addition, protection is to be provided by the fixed fire-extinguishing system
covering the Category A machinery space in which the purifier room is located, see
4-7-2/1.1.1.

iv)
Means of closing ventilation openings and stopping the ventilation fans, purifiers,
purifier-feed pumps, etc. from a position close to where the fire extinguishing system
is activated.
If it is impracticable to locate the fuel oil purifiers in a separate room, special consideration
will be given with regard to location, containment of possible leakage, shielding and
ventilation. In such cases, a local fixed water-based fire-extinguishing system complying with
the provisions of 4-7-2/1.11.2 is to be provided. Where, due to the limited size of the category
A machinery space, a local fixed water-based fire-extinguishing system is not provided, then
an alternative type of local dedicated fixed fire-extinguishing system is to be provided for the
protection of the purifiers. In either case, the local fire extinguishing system is to activate
automatically or manually from the centralized control station or other suitable location. If
automatic release is provided, additional manual release is also to be arranged.

isolation is not to affect the operation of the other engines and is to be operable from a
position not rendered inaccessible by a fire on any of the engines. See also 4-7-2/1.9.6vii).

(Add the new third paragraph.)
The strength of hatch covers and their arrangements are generally to be determined in accordance with
the applicable parts of 3-2-15/7, and 3-2-15/9.
Where it is intended that the covers may carry containers, the requirements of 3-2-15/9.9 are also to
be satisfied.
For hatch covers and hatch coamings in holds intended for carriage of liquid, the structure is to be of
adequate strength to resist the upward pressure of ballast water or cargo oil in the holds caused by the
pitch and roll motions of the vessel specified in load cases 5 and 7 in Section 5-3-3/Table 1. The
strength of hatch covers is to be determined in accordance with the requirements of 5-3-6/15.3 and
5-3-6/15.9 through 5-3-6/15.15, as applicable. The cleats and their connections are to be designed
with a higher factor of safety than the cover itself. Where p/v valves are fitted, the strength of the
covers is to be verified for a pressure corresponding to the p/v valve setting.
Hatch covers, located forward of 0.25L from the FP, are to be in compliance with 5-3-6/15.
