Q: Fire protection regulation

A: For Class 7 vessels

Vessel to be fitted with a fire main, water service pipes and hydrants with no other connection other then for washing down.

Sufficient appliances to ensure at least two jets of water to any point from separate hydrants.

One hoses for every 30m of ship’s length (minimum 5). Total length of at least 60% ship’s length, Plus one spare hose. (Engine Room extra)

Sufficient to produce two jets of water at any point. Each machinery / boiler space to have at least 2 hydrant, one each side, plus one in the shaft tunnel.

Two fire pumps + one other pumps (general service, ballast or bilge’s pump) each capable of producing two jets of water from separate hydrants. If all pumps are in same compartment (usually E. R.) an independently driven emergency fire pumps is required out side that compartment.

Sufficient extinguisher so that at least one is readily available in any part of the accommodation or service space. Not less then 5 ( 3 if under 1000t) , spare charges for 50% of each type unless not readily recharged in which case an additional extinguisher of the same type must be provided.

Ships 2000t or over to be provided with fixed gas smothering system for every cargo space. An exemption may be granted if ship only carries bulk cargoes of low fire hazard and the v/l is fitted with steel hatches and all openings to that compartment can be sealed. Ro/Ro cargo space not capable of being sealed to be protected by a fixed water spraying system instead.

A fixed smothering system-pressure water, gas or foam. In each boiler space a large foam extinguisher (min.135 litres) or CO2 equivalent (min. 45 kg). Plus one portable extinguishers plus 0.3m³ sand and a scoop.

A fixed smothering system-pressure water, gas or foam, and a 45 litre foam extinguisher or a 16 kg CO2 extinguisher, plus a portable foam applicator unit. Sufficient portable extinguishers (min 2) so that at least one is not more than 10m walking distance from any point.

Sufficient 45 litre foam or 16 kg CO2 extinguisher to reach any part or a fixed system - water spraying or gas smothering. Sufficient portable extinguishers (min 2) so that at least one is not more then 10m walking distance from any point. Where such space are periodically unmanned, a fixed system - water spraying or gas smothering.

Automatic fire detection and alarm system

General

Fire / smoke detection system. No steam smothering.

All nozzles to be dual purpose type.

liquid : between 9 and 13.2 litters., Dry powder: min 4.5 kg., CO2: min 3 kg. Max. weight 25.6 kg., Not more then 50% of extinguishers of dry powder.

Quantity : 30% of largest cargo compartment (45 % if Ro-Ro deck) and 40% Engine room, Min. Rate of flooding (E.R. ) 85% of total volume in two minutes ( if Ro-Ro deck must provide two thirds of CO2 within 10 minuets.

To be provide with means of stopping fans, machinery, pumps, etc. from outside of space. Also means of closing skylight, doorway, vents, and other openings from outside the space.

Outfit to widely separated, and to consist of :

Adjacent to landing area:

Mechanical ventilation system (at least 6 changes / hours). At least 2 portable extinguishers for every 40m length of deck spaces (1 at each access point). Fixed water spraying system ( water curtains ). Plus 3 water fog application units.

Displayed in public place for guidance of Master and officers. A duplicate set to be stored in a prominently marked watertight enclosure outside the deck house for the assistance of shore fire fighting personnel.

Q: What is requirements for CO2 that you must have to have on board for cargo hold and Machinery space separately?

A: For cargo hold- 30 % vol. of largest cargo hold if carried. 45 % vol. if cargo hold carry vehicles and vehicles are fitted with F. O. tanks and tanks are full of F. O.

For machinery space-40 % vol. of Machinery spaces excluding Engine casing. 35 % vol. of machinery spaces including Engine casing.

Q: Squat?

A: Squat is an increase in draught caused by a vessel travelling through the water at a significant speed with a limited under keel clearance.

Whilst it can occur in relating deep water, it is more pronounced when the depth of the water is less than twice the draft in other words, the under keel clearance is less than the v/l’s draught.

There is also likely to be a change in trim since the LCB is likely to change with change of draught, thereby creating a trimming moment.

Factors increasing squat

  • High speed ( squat α speed²)
  • High propeller speed
  • Deep draught
  • Shallow depth of water
  • High block co-efficient
  • Broad beam
  • Narrow channel
  • Large trim

Sign that v/l is experiencing shallow water effect

  • Speed decrease
  • R.P.M. decrease
  • vibration may occur
  • Steering may affected v/l becomes sluggish to manoeuvre.
  • Ship made waves increase in amplitude.
  • Ship wake changes colour / become muddy.
