SECTION 1 SAFETY REQUIREMENTS FOR NEW AND EXISTING PASSENGER SHIPS THE KEEL OF WHICH WAS LAID OR WHICH WERE AT A SIMILAR STAGE OF CONSTRUCTION BEFORE 19 SEPTEMBER 2021 ENGAGED ON DOMESTIC VOYAGES CHAPTER I GENERAL PROVISIONS 1. Section 1 applies to new and existing passenger ships the keel of which was laid or which were at a similar stage of construction before 19 September 2021.

4. Existing class C and D ships do not have to comply with the regulations of Chapters II-1 and II-2 of this Section, provided that the Administration of a flag State, which flag such ships are entitled to fly, ensures that they comply with the flag State’s national rules and that such rules guarantee an equivalent level of safety to those applicable to new class C&D or existing class B ships.

6. Regardless of what is provided in Article 6.1(b), Class D ships not extending their voyage outside of Sea Area A 1, as defined in Regulation IV/2.12 of the 1974 SOLAS Convention, do not have to comply with the carriage requirements in Chapter IV of the 1974 SOLAS Convention, but shall at least comply with the provisions in Chapter IV of this Annex.

7. The provisions for navigation bridge visibility in Regulation V/22 of the 1974 SOLAS Convention, shall as far as is practicable and reasonable apply also to ships of less than 55 meters’ in length, where ‘length’ is as defined in Regulation V/2 of the 1974 SOLAS Convention.

8. Wherever the application of an IMO resolution is required in this Section for existing ships, ships constructed until two years after the date of adoption by IMO of such resolution need not comply with such resolution provided they comply with the applicable previous resolution(s), if any.

12. Provisions applicable to CLASS A RO-RO PASSENGER SHIPS: Chapter II-1/B-2, Regulations II-1/B-2/17-2 and II-1/B-2/20. CHAPTER II-1 CONSTRUCTION — SUBDIVISION AND STABILITY, MACHINERY AND ELECTRICAL INSTALLATIONS PART A GENERAL

1. Regulation II-1/A/1: Definitions relating to Part B (R 2) NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS: .1 .1 Subdivision load line is the waterline used in determining the subdivision of the ship. .2 Deepest subdivision load line is the waterline which corresponds to the greatest draught permitted by the subdivision requirements which are applicable. .2 Length of the ship is the length measured between perpendiculars taken at the extremities of the deepest subdivision load line. .3 Breadth of the ship is the extreme width from outside of frame to outside of frame at or below the deepest subdivision load line. .4 Draught is the vertical distance from the moulded base line amidships to the subdivision load line in question. .5 Deadweight is the difference in tonnes between the displacement of a ship in water of a specific gravity of 1,025 at the load waterline corresponding to the assigned summer freeboard and the lightweight of the ship. .6 Lightweight is the displacement of a ship in tonnes without cargo, fuel, lubricating oil, ballast water, fresh water and feedwater in tanks, consumable stores, and passengers and crew and their effects.

.7 Bulkhead deck is the uppermost deck up to which the transverse watertight bulkheads are carried. .8 Margin line is a line drawn at least 76 mm below the upper surface of the bulkhead deck at side. .9 Permeability of a space is the percentage of that space which can be occupied by water. The volume of a space which extends above the margin line shall be measured only to the height of that line. .10 Machinery space is to be taken as extending from the moulded base line to the margin line and between the extreme main transverse watertight bulkheads, bounding the spaces containing the main and auxiliary propulsion machinery, and boilers serving the needs of propulsion. .11 Passenger spaces are those spaces which are provided for the accommodation and use of passengers, excluding baggage, store, provision and mail rooms. .12 Watertight in relation to structure means capable of preventing the passage of water through the structure in any direction under the head of water likely to occur in the intact or damage condition. .13 Weathertight means that water will not penetrate into the ship in any sea conditions.

.14 Ro-ro passenger ship means a passenger ship with ro-ro cargo spaces or special category spaces as defined in Regulation II-2/A/2.

2. Regulation II-1/A/2: Definitions relating to Parts C, D, and E (R 3) NEW CLASS B, C AND D AND EXISTING CLASS B SHIPS: .1 .1 Steering gear control system is the equipment by which orders are transmitted from the navigating bridge to the steering gear power units. Steering gear control systems comprise transmitters, receivers, hydraulic control pumps and their associated motors, motor controllers, piping and cables. .2 Main steering gear is the machinery, rudder actuators, steering gear power units, if any, and ancillary equipment and the means of applying torque to the rudder stock (e.g. tiller or quadrant) necessary for effecting movement of the rudder for the purpose of steering the ship under normal service conditions.

.2 Steering gear power unit is: .1 in the case of electric steering gear, an electric motor and its associated electrical equipment; .2 in the case of electrohydraulic steering gear, an electric motor and its associated electrical equipment and connected pump; .3 in the case of other hydraulic steering gear, a driving engine and connected pump. .3 Auxiliary steering gear is the equipment other than any part of the main steering gear necessary to steer the ship in the event of failure of the main steering gear but not including the tiller, quadrant or components serving the same purpose. .4 Normal operational and habitable condition is a condition under which the ship as a whole, the machinery, services, means and aids ensuring propulsion, ability to steer, safe navigation, fire and flooding safety, internal and external communications and signals, means of escape, and emergency boat winches, as well as the designed comfortable conditions of habitability are in working order and functioning normally.

.14(b) Machinery spaces of category A are those spaces and trunks to such spaces which contain: .1 internal combustion machinery used for main propulsion; or .2 internal combustion machinery used for purposes other than main propulsion where such machinery has in the aggregate a total power output of not less than 375 kW; or .3 any oil-fired boiler or oil fuel unit. .15 Power actuating system is the hydraulic equipment provided for supplying power to turn the rudderstock, comprising a steering gear power unit or units, together with the associated pipes and fittings, and a rudder actuator. The power actuating systems may share common mechanical components, i.e. tiller, quadrant and rudder stock, or components serving the same purpose. .16 Control stations are those spaces in which the ship’s radio or main navigating equipment or the emergency source of power is located or where the fire recording or fire control equipment is centralised.
