Maritime, Safety, Regulations
The maximum working pressure ‘PS is the maximum gauge pressure which may be exerted under normal conditions of use of the vessel. Exceptions should be provided for in cases where the size or nature of the safety component for lifts does not allow it. Lifeboats and rescue boats shall be lowered at successive drills in accordance with the provision of SOLAS Regulation III/19.3.3.2, 3.3.3, 3.3.6, and 3.3.7, as amended. If there is more than one subdivision load line, the alternative conditions shall be identified by the notations C.2, C.3, C.4 etc. Indication must be provided at the fire control panel in the continuously manned central control station whether each of the remote-controlled doors is closed. This test shall be carried out in the most advanced stage of the fitting-out of the ship. Where a hose test is not practicable because of possible damage to machinery, electrical equipment insulation or out fitting items, it may be replaced by a careful visual examination of welded connections, supported where deemed necessary by means such as a dye penetrant test or ultrasonic leak test or an equivalent test. Depending on the subdivision standard the damage may not affect any bulkhead or may only affect a bulkhead below the bulkhead deck or only bulkhead above the bulkhead deck or various combinations. When a bulkhead above the ro-ro deck is assumed damaged, both compartments bordering the bulkhead shall be assumed flooded to the same height of water surface as calculated in paragraph 1.1 or 1.3. The bilge pumping system required by paragraph .1.1 shall be capable of operation under all practicable conditions after a casualty whether the ship is upright or listed. The manufacturers maximum recommended load (fuel, water, provisions, miscellaneous equipment and people (in kilograms)) for which the watercraft was designed, shall be determined in accordance with the design category (Section 1), stability and freeboard (point 3.2) and buoyancy and flotation (point 3.3). The operator or master of the ship shall ensure that sufficient time is available in the operating schedule to allow the expanded inspection to be carried out. The waterbath shall be designed in such a way that the level of immersion of the birds can be easily adapted. Independent power bilge pumps situated in machinery spaces shall have direct suctions from these spaces, except that not more than two such suctions shall be required in any one space. Prozentsatz des freien Plattenplatzes als Auslöseschwelle für die erstmalige Warnung. Falls der Prozentsatz des freien Platzes unter diesen Wert fällt, wird eine Warnung angezeigt. All discharge pipes from starting air compressors shall lead directly to the starting air receivers, and all starting pipes from the air receivers to main and auxiliary engines shall be entirely separate from the compressor discharge pipe system. It is assumed that the ventilators of the damage compartment of the actual ship are adequate for unhindered flooding and movement of the flood water. a transverse or longitudinal bulkhead shall be considered intact if all parts of it lie inboard of vertical surfaces on both sides of the ship, which are situated at a distance from the shell plating equal to one-fifth of the breadth of the ship, as defined in Regulation II-1/2, and measured at right angles to the centreline at the level of the deepest subdivision load line; These arrangements shall include handrails and gratings or other non-slip surfaces to ensure suitable working conditions in the event of hydraulic fluid leakage. goods alone if the carrier is accessible, that is to say a person may enter it without difficulty, and fitted with controls situated inside the carrier or within reach of a person inside the carrier. Lifeboats shall be stowed attached to launching appliances, and on passenger ships of 80 metres in length and upwards, each lifeboat shall be so stowed that the after end of the lifeboat is not less than 1,5 times the length of the lifeboat forward of the propeller. In approval of structural precautions for fire protection in new ships, account shall be taken of the risk of heat transfer between heat bridges at intersection points, and where the thermal barring devices terminate. .9 Main vertical zones are those sections into which the hull, superstructure, and deckhouses are divided by ‘A class divisions, the mean length and width of which on any deck does not in general exceed 40 metres. The arrangement of the foam generator delivery ducting shall be such that a fire in the protected space will not affect the foam generating equipment. As from 1 January 2008 the ships referred to in Article 3(1) shall either not bear organotin compounds which act as biocides in anti-fouling systems on their hulls or external parts and surfaces, or bear a coating that forms a barrier to such compounds leaching from the underlying non-compliant anti-fouling system. One indicating unit shall be located on the navigating bridge if the control panel is located in the main fire control station. Ventilation systems shall be designed, constructed and maintained so that the welfare of the animals is constantly ensured, taking into account the expected range of weather conditions. The noise measurement shall be carried out during a complete cycle beginning with the empty container and completed when 120 bottles have been thrown into the container The nozzle shall be capable of producing effective foam suitable for extinguishing an oil fire, at a rate of at least 1,5 m3 per minute; The significant wave heights (hS) shall be used for determining the height of water on the car deck when applying the specific stability requirements contained in Annex However, subparagraphs .5.2 and .5.3 do not apply to stairway enclosures which constitute individual main vertical zones and for the main vertical zones in the fore or aft end of a ship, which do not contain spaces of categories (6), (7), (8) or (12) defined in Regulation II-2/B/4. 2.2.2(a) The model in way of the assumed damages must be as thin as practically possible to ensure that the amount of flood water and its centre of gravity is adequately represented. Each gas-consuming appliance must be supplied by a separate branch of the distribution system, and each appliance must be controlled by a separate closing device. power-operated doors shall be provided with a control system of an approved type which shall be able to operate in case of fire, this being determined in accordance with the Fire Test Procedure Code. Suitable arrangements shall be made to permit the release of smoke in the event of fire, from the space to be protected. In new class B, C and D ships constructed on or after 1 January 2003, the ventilation systems for machinery spaces of category A, vehicle spaces, ro-ro spaces, galleys, special category spaces and cargo spaces shall, in general, be separated from each other and from the ventilation systems serving other spaces. The means of control of any such systems shall be readily accessible and simple to operate and shall be grouped together in as few locations as possible at positions not likely to be cut off by a fire in the protected space. Lifeboats shall be capable of being boarded either directly from the stowed position or from an embarkation deck, but not both. The control panel in the central control station shall be capable of indicating open or closed positions of fire doors, closed or off status of the detectors, alarms and fans. If a household vacuum cleaner has a head width of over 0,320 m, then the figure of 0,320 m shall be substituted for head width in this calculation. An engineers alarm shall be provided to be operated from the engine control room or at a manoeuvring platform as appropriate, and shall be clearly audible in the engineers accommodation and/or the navigating bridge as appropriate. Two lifebuoys shall be equipped with a self-activating smoke signal and a self-activating light; they shall be capable of quick release from the navigation bridge. All electrical cables and wiring external to equipment shall be at least of a flame-retarding type and shall be so installed as not to impair their original flame-retarding properties. Stairway enclosures shall have direct access with the corridors and be of a sufficient area to prevent congestion, having in view the number of persons likely to use them in an emergency. The lower edge of the freeing port opening must be no higher than 2 cm above the bulkhead deck and the upper edge of the opening no higher than 0,6 m (see figure 8). If the remote control system of the propulsion machinery is designed for automatic starting, the number of automatic consecutive attempts which fail to produce a start shall be limited in order to safeguard sufficient starting air pressure for starting locally. Dead ship condition is the condition under which the main propulsion plant, boilers and auxiliaries are not in operation due to the absence of power. As far as practicable, parts of the oil fuel system containing heated oil under pressure exceeding 0,18 N/mm2 shall not be placed in a concealed position such that defects and leakage cannot readily be observed. However, where a pipe penetration is made of steel or equivalent material having a thickness of 3 mm or greater and a length of not less than 900 mm (preferably 450 mm on each side of the division) and no openings, testing is not required. the master shall ensure that an effective system of supervision and reporting of the closing and opening of such accesses referred to in paragraphs .1.2 and .1.3 is implemented; and The gas stunner shall be equipped to measure continuously, display and record the gas concentration and the time of exposure, and to give a clearly visible and audible warning if the concentration of gas falls below the required level. Containers for the storage of fire extinguishing medium and associated pressure components shall be designed to appropriate codes of practice having regard to their locations and maximum ambient temperatures expected in service. .1 Except in cargo spaces, mail rooms, baggage rooms, or refrigerated compartments of service spaces, all linings, grounds, draughtstops, ceilings, and insulations shall be of non-combustible materials. All new ships of class B, C and D and existing class B ships shall be specially considered by the Administration of the flag State as to whether or not their machinery spaces may be periodically unattended and if so whether additional requirements to those stipulated in these regulations are necessary to achieve equivalent safety to that of normally attended machinery spaces. The righting lever GZ shall be at least 0,20 metres at an angle of heel equal to or greater than 30 °.
