Section 1 General

1.1.1 This Chapter applies to propelled passenger ships, with or without sleeping accommodation, having the machinery aft or amidships.

1.1.2 The scantlings and arrangements are to be as required in Pt 4, Ch 1 Dry Cargo Ships as far as applicable and as specified otherwise in this Chapter.

1.1.3 The structural requirements of this Chapter are intended to cover the midship region as defined in Pt 3, Ch 3, 2.2 Definition of midship regionof ships not exceeding 135 m in length, having a ratio of length to depth not exceeding 35 and in general, a ratio of breadth to depth not exceeding five.

1.1.4 The structural requirements forward and aft of the midship region are to comply with Pt 3, Ch 5 Fore End and Aft End Structure and Pt 3, Ch 6 Machinery Spaces so far as applicable. The remaining requirements of Pt 3 Ship Structures (General) are also to be complied with as appropriate to the intended arrangements.

1.1.5 The requirements in this Chapter are based on the European Standard laying down Technical Requirements for inland Navigation Vessels (ES-TRIN), in particular Chapter 19, concerning special requirements applicable to Passenger Vessels.

1.1.6 Although the contents of this Chapter takes part of the regulations mentioned in Pt 4, Ch 9, 1.1 Application 1.1.5 into account, the issue of a Certificate on behalf of the relevant Authorities requires full compliance with these Regulations.

1.1.7 Attention is drawn to other National and International technical and operational requirements of countries where the ship is registered or operating. These requirements are outside classification as defined in these Rules and Regulations but may however be accepted in lieu of the requirements in Pt 4, Ch 9, 1.1 Application 1.1.5 as deemed acceptable by LR.

1.1.8 At the request of the owner or builder and as delegated by the competent National Authority as referred to in Pt 4, Ch 9, 1.1 Application 1.1.5 and Pt 4, Ch 9, 1.1 Application 1.1.7, LR can also issue a Statement of Compliance with specific National or International requirements.

1.2.1 For the purpose of this Chapter, the following definitions apply:

1. ‘bulkhead deck’: the deck to which the required watertight bulkheads are taken and from which the freeboard is measured;

2. ‘freeboard’: the distance between the plane of maximum draught and a parallel plane passing through the lowest point of the gunwale or, in the absence of a gunwale, the lowest point of the upper edge of the ship’s side;

3. ‘residual freeboard’: the vertical clearance available, in the event of the vessel heeling over, between the water level and the upper surface of the deck at the lowest point of the immersed side or, if there is no deck, the lowest point of the upper surface of the fixed ship’s side;

4. ‘margin line’: an imaginary line drawn on the side plating not less than 10 cm below the bulkhead deck and not less than 10 cm below the lowest non-watertight point of the side plating. If there is no bulkhead deck, a line drawn not less than 10 cm below the lowest line up to which the outer plating is watertight shall be used;

5. ‘passenger area’: areas on board intended for passengers and enclosed areas such as lounges, offices, shops, hairdressing, salons, drying rooms, laundries, saunas, toilets, washrooms, passageways, connecting passages and stairs not encapsulated by walls;

6. ‘machinery space’: the space extending from the baseline to the margin line and between the transverse watertight bulkheads containing the main propelling and auxiliary machinery, boilers and coal bunkers if any.

7. ‘permeability of a space’: the percentage of a space which can be occupied by water.

8. ‘stairwell’: the well of an internal staircase or of a lift;

9. ‘passageway’: an area intended for the normal movement of persons and goods;

10. ‘safe area’: the area which is externally bounded by a vertical surface running at a distance of 1/5 of the maximum moulded breadth of the waterline at the maximum design draught parallel to the course of the hull at right angles to the centreline.

1.3.1 The intact and damage stability of the vessel is to be approved by the competent National Authorities in accordance with the regulations as stipulated in Pt 4, Ch 9, 1.1 Application 1.1.5.
