Scope of classification

Classification covers the vessel's hull and machinery including electrical installations as well as special equipment and installations as far as agreed in the respective classification contract. Classification aims primarily at ensuring reliability of the hull structure and machinery systems on board resulting in an adequate level of safety of personnel and environmental protection. However, classification is not intended to ensure the effectiveness of the intended missions.

Structures, machinery and equipment determining the type of vessel are subject to examination within the scope of classification, in accordance with the character of classification and affixed class notations. Other systems and components may be included in the classification and/or certification procedure upon agreement with the Society's contractual partner and the Building Yard.

It is assumed that all parties involved in the planning and design, materials and components production and installation have the professional qualifications required and/or suitable facilities/equipment for fabrication. This will normally be established or confirmed by means of a certified quality assurance management system in accordance with ISO 9000, or equivalent

Purpose of the rules

The rules for classification and surveys of inland navigation vessels cover the classification of inland navigation vessels as defined in [1.2.5].

The rules published by the Society give the requirements for the assignment and the maintenance of class for inland navigation vessels.

Class assigned to a vessel reflects the discretionary opinion of the Society that the vessel, for declared conditions of use and within the relevant time frame, complies with the Rules applicable at the time the service is rendered.

General terms and conditions valid at the time of signing of the contract with the party ordering the classification apply.
