Section 1 Conditions for classification

1.1 General

1.1.1 These Rules and Regulations are framed for Inland Waterways Ships operating in Zone 3. Proposed scantlings and arrangements for ships intended to operate in Zones 2 or 1, will be specially considered. See also Pt 1, Ch 2, 2.1 Definitions 2.1.2 for Zone definitions.

1.1.2 Ships referred to in this Chapter are defined in Pt 3 Ship Structures (General) and Pt 4 Ship Structures (Ship Types) of these Rules.

Machinery referred to in this Chapter is defined in Pt 5 Main and Auxiliary Machinery and Pt 6 Control, Electrical and Fire of these Rules.

1.1.3 Ships built in accordance with Lloyd’s Register’s (hereinafter referred to as LR) Rules and Regulations, or in accordance with requirements equivalent thereto, will be assigned a class in the Register Book and will continue to be classed as long as they are found, upon examination at the prescribed surveys, to be maintained in accordance with the requirements of the Rules. Classification will be conditional upon compliance with LR’s requirements for both hull and machinery and with the certification requirements of Pt 1, Ch 2, 1.1 General.

1.1.4 The Classification Committee, in addition to requiring compliance with LR’s Rules, may require to be satisfied that ships of special types are suitable for the conditions of the service contemplated.

1.1.5 Any damage, defect or breakdown, grounding, serious deficiency, detention or arrest which could invalidate the conditions for which a class has been assigned, is to be reported to LR without delay. Any detention or arrest is also to be reported to LR without delay.

1.1.6 The Rules are framed on the understanding that ships will be properly loaded and handled. They do not, unless stated or implied in the class notation, provide for special distributions or concentrations of loading. The Classification Committee may require additional strengthening to be fitted in any ship, which, in their opinion, would otherwise be subjected to severe stresses due to particular features in the design, or where it is desired to make provision for exceptional loaded or ballast conditions. In such cases, particulars are to be submitted for consideration, see also the relevant ship type Chapters in Pt 4 Ship Structures (Ship Types).

1.1.7 The Rules are framed on the understanding that ships will not be operated in environmental conditions more severe than those agreed for the design basis and approval, without the prior agreement of LR.

1.1.8 For ships, the arrangements and equipment of which are required to comply with the requirements of either the:

  • European Agreement concerning the international carriage of dangerous goods by inland waterways (ADN); or
  • European Standard laying down Technical Requirements for Inland Navigation vessels (ES-TRIN); or
  • Any National regulations specified by the Government of the Flag State,

and applicable Amendments thereto, the Classification Committee requires the applicable Certificates to be issued by a National Administration, or by LR, or by an IACS Member when so authorised.

1.2 Advisory services

1.2.1 The Rules do not cover certain technical characteristics, such as stability, trim, hull vibration, etc. but advice may be given on such matters without any assumption of responsibility for such advice.
