ROLES OF CLASSIFICATION SOCIETIES AND IMPORTANCE OF IACS
ROLE OF CLASSIFICATION SOCIETY:-
Classification societies are organizations that establish and apply technical standards in relation to the design, construction and survey of marine related facilities including ships and offshore structures. These standards are issued by the society as published rules. They publish rules and regulations concerning:-
1) The structural strength of all essential parts of hull and its appendages.
2) The safety and reliability of the propulsion and steering system and other auxiliary system
3) All machinery (including electrical)
4) Materials of construction
5) Rules for special types of vessel
6) Rules for ship equipment etc
The classification society service is mainly on setting/ updating and monitoring hull structure and essential shipboard engineering system, during construction and throughout a ship's service life. A vessel must be in class all times while in service. For this vessels are being surveyed by classification society surveyor at regular intervals. They carry out research and development in ship's structure, engineering design and other safety aspect. They also provide technical advisory services to shipowner and operator.
IMPORTANCE OF IACS:-
IACS was formed in 1968 with seven leading societies. In 1969 IACS was given consultative status with IMO. It is the non governmental organization with observer status which is able to develop and apply rules for structure, equipment and machinery. IACS frequently provides technical input to IMO notably for studies into specific ship type and various safety and pollution prevention issues. IACS is also playing a vital role in the introduction/ implementation of the ISM code. The program of periodical hull survey consists of annual, intermediate and renewal survey. These are carried out by surveyors to assess any damage or defect which would impair the structural capability or watertight integrity of hull. Also IACS surveyors survey in new construction which are built under their supervision. For this the constructional details and all necessary particulars relevant to hull, equipment and machinery are submitted for approval of classification society before work is commenced. Materials used and workmanship should be satisfactory according to rules. IACS pass Unified resolution (UR) and Unified interpretation(U I).
UNIFIED REQUIREMENTS:-
These are adopted resolutions on matters directly connected to or covered by specific rule requirement and practices of classification societies and the general philosophy on which the rules and practices of classification societies are established. Subject to the ratification of the governing body of each member society,unified requirements shall be incorporated in the rules and practices of member societies, within one year of approval by the IACS general policy group. Unified requirements are minimum requirements and each member is free to set more stringent requirements.
UNIFIED INTERPRETATION:-
These are adopted resolutions on matters arising from implementing the requirements of IMO conventions or recommendation. Such adopted resolutions can involve uniform interpretation of convention, regulation or IMO resolution on those matters which in the convention are left to the satisfaction of administration or vaguely worded.
