This fixed fire detection and alarm system may be combined with other fire detection and alarm systems required onboard the vessel. The fire control panel is to be located on the navigation bridge or in the fire fighting station. If located in the fire fighting station, a repeater panel is to be fitted on the navigation bridge. Propulsion machinery space fire is to be alarmed in the centralized control station.

29.5.2 Temporarily Disconnecting Alarms

A fire detector loop or detector(s) covering the unattended machinery space may be temporarily disabled, for example, for maintenance purposes and such action is to be clearly indicated at the fire control panel and at the centralized control station described in 4-7-4/29.5.1. Disabled loop or detectors are to be reactivated automatically after a preset time period.

33 Firefighting Arrangements for Propulsion Machinery Space Fires

(Revise Subparagraphs 4-7-4/33.3.1, 4-7-4/33.3.2 and 4-7-4/33.3.5, add new Subparagraph 4-7-4/33.3.3, and renumber subsequent Subparagraphs accordingly, as follows.)

33.3 Fire-fighting Controls

Firefighting arrangements are to be provided with remote manual controls for the operations detailed in the following list. These controls are to be capable of being tested to the satisfaction of the Surveyor.

33.3.1 (2010) Stopping of ventilation fans serving the machinery-space. See 4-6-2/19.1.1.

33.3.2 (2010) Stopping of fuel oil, lubricating oil and thermal oil system pumps. See 4-6-2/19.1.2.

33.3.3 (2010) Stopping of forced and induced draft fans of boilers, inert gas generators and incinerators, and of auxiliary blowers of propulsion diesel engines. See 4-6-2/19.1.2.

33.3.4 Closing propulsion-machinery space fuel oil tanks suction valves. (See 4-5-1/5.5).

33.3.5 (2010) Closing machinery-space skylights, openings in funnels, ventilator dampers and other openings.

33.3.6 Closing machinery-space watertight and fire-resistant doors.

33.3.7 Starting the emergency generator or connecting a source of emergency power, unless automatic operation is provided.

33.3.8 (2004) Operation of a fire pump located outside of the propulsion-machinery space, including associated valves necessary to deliver the required capacity to the fire main. However, valves located near the pump need not be provided with remote operation from the fire fighting station if they are kept locked open (LO) or closed (LC), as appropriate, to provide immediate water supply to the fire main. The position of the valves (open or closed) is to be clearly marked. Where the sea chest valve is located in the same compartment as the fire pump and the sea chest valve is kept locked open, a high-level bilge alarm is to be fitted in the fire pump space. If the sea chest is located in a different space than the compartment containing the fire pump, then a high-level bilge alarm is to be fitted in the fire pump space, as well as the compartment containing the sea chest, in order to detect possible flooding in each of these spaces. The high-level bilge alarm is to sound in the centralized control station.

33.3.9 Releasing of the fire-fighting media for the propulsion-machinery space. This release is to be manual and not initiated automatically by signals from the fire-detecting system.

APPENDIX 2 DAMAGE STABILITY GUIDELINES FOR OFFSHORE SUPPORT

VESSELS

(Revise Item i) of Subsection 5-10-A2/3, and add new Note 5, as follows.)

3 (2010)

The following damage assumptions are to be applied:

i) Damage is to be assumed to occur anywhere in the vessel’s length between transverse watertight bulkheads. The longitudinal extent of damage is:

a) 3 m (9.84 ft) plus 3% of the vessel’s length (L), when the length is greater than 43 m (141 ft)

b) 10% of the vessel’s length (L), when the length not is greater than 43 m (141 ft)

ii) The vertical extent of damage is to be assumed from the underside of the cargo deck, or the continuation thereof, for the full depth of the vessel.

iii) The transverse extent of damage is to be assumed as 760 mm (30 in.), measured inboard from the side of the vessel perpendicularly to the centerline at the level of the summer load waterline.

Note: 1. A transverse watertight bulkhead extending from the vessel’s side to a distance inboard of 760 mm (30 in.) or more at the level of the summer load line joining longitudinal watertight bulkheads is to be considered as a transverse watertight bulkhead for the purpose of the damage calculations.

2. If pipes, ducts or tunnels are situated within the assumed extent of damage, arrangements are to be made to ensure that progressive flooding cannot thereby extend to compartments other than those assumed to be floodable for each case of damage.

3. If damage of a lesser extent than that specified in 5-10-A2/3i), 5-10-A2/3ii) and 5-10-A2/3iii) results in a more severe condition, such lesser extent is to be assumed.

4. Where a transverse watertight bulkhead is located within the transverse extent of assumed damage and is stepped in way of a double bottom or side tank by more than 3.05 m (10 ft), the double bottom or side tanks adjacent to the stepped portion of the transverse watertight bulkhead is to be considered as flooded simultaneously.

ABS RULES FOR BUILDING AND CLASSING STEEL VESSELS UNDER 90 METERS (295 FEET) IN LENGTH . 2006 21

5. If the distance between adjacent transverse watertight bulkheads or the distance between the transverse planes passing through the nearest stepped portions of the bulkheads is less than the longitudinal extent of damage given in i), only one of these bulkheads should be regarded as effective.

6. For a vessel exclusively operating for well stimulation service, assumed damage occurs anywhere in the vessel’s length at any transverse watertight bulkhead.
