Section 1 Conditions for classification

1.1.1 The requirements of these Regulations apply to ships which operate principally within the limits of the Great Lakes and the River St. Lawrence, with the seaward limit, as a straight line drawn from Cap des Rosiers on the Gaspe Peninsula to the west point of Anticosti Island and from Anticosti Island to the north shore of the River St. Lawrence along the meridian of longitude sixty-three degrees west.

1.1.2 It is required that ships classed in accordance with these Regulations will be laid up in fresh water each winter at a River St. Lawrence or a Great Lakes port.

1.1.3 Ships intended to be employed on the Great Lakes and River St. Lawrence and built in accordance with LR's Rules and Regulations for the Classification of Ships for Service on the Great Lakes and River St. Lawrence or with alternative arrangements equivalent thereto, will be assigned a class in the Register Book and will continue to be classed so long as they are found upon examination at the prescribed surveys to be maintained in accordance with the requirements of these Regulations. Classification will be conditional upon compliance with LR's requirements for both hull and machinery.

1.1.4 Except where stated otherwise by these Rules and Regulations, the relevant requirements of LR's Rules and Regulations for the Classification of Ships will apply.

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

1.1.6 The Rules for Ships are based on the understanding that ships will be properly loaded and handled. They do not, unless stated in the class notation, provide for special distribution or concentration of loading. The Committee may also require additional strengthening to be fitted in any ship which in their opinion may be subjected to severe stresses due to particular features in the design or when it is desired to make provision for exceptional loaded or ballasted conditions. In these cases particulars are to be submitted for consideration.

1.2.1  Class 100A1 with special service notation. This class will be assigned to ships intended to operate on the Great Lakes and River St. Lawrence, and built in accordance with the Rules for Ships. The class notation affixed to the character in the Register Book will indicate the particular service for which the ship is approved. The geographical and where applicable, seasonal limits of the service will be defined.

1.2.2  Class A1 (For restricted service). This class will be assigned to ships intended to trade only within specially sheltered waters, such as harbours or rivers within the limits as defined in Ch 2, 1.1 General 1.1.1, provided the scantlings, arrangements and equipment are approved by the Committee as suitable for such service. The class notation affixed to the character will indicate the geographical limits for which the ship has been approved.

1.2.3 The notation Winters in the Great Lakes may be assigned to the class of a ship, in order to permit five year docking survey intervals, when it has been requested and confirmed by the Owner and agreed by the Committee, that the ship will lay up each winter in fresh water, in a River St. Lawrence or a Great Lakes port.

1.3.1 In addition to any class notations, an appropriate descriptive note shall be entered in column 6 of the Register Book indicating the type of ship in greater detail than is contained in the class notation, and/or providing additional information about the ship’s design and construction. This descriptive note is not a LR classification notation and is provided solely for information.

1.3.2 ShipRight(). Where one or more of LR’s ShipRight procedures as detailed in the Rules and Regulations for the Classification of Ships, July 2022, Pt 1, Ch 2, 2.8 Descriptive notes 2.8.2 have been satisfactorily applied, then a descriptive note showing the associated characters of the procedure(s) within brackets will, at the Owner’s request, be entered in column 6 of the Register Book, preceded by the word ShipRight, e.g. ShipRight(IHM, SERS).

1.4.1 The materials used in the repair of hull and machinery are to be manufactured, tested and inspected in accordance with the requirements of Rules for the Manufacture, Testing and Certification of Materials, July 2022. The steel is to be manufactured by an approved process at works recognised by the Committee. Alternatively, tests to the satisfaction of the Committee will be required to demonstrate the suitability of the steel.
