(a) Define a Classification Society (6 marks)
A Classification Society is:
- An independent, non-governmental organisation which establishes and applies technical standards (Rules) for the design, construction and survey of ships and offshore structures.
- Its role is to ensure that vessels are built and maintained to minimum standards of safety, reliability, and environmental protection.
- Societies carry out regular surveys (annual, docking, special) to verify compliance with their rules and with international conventions (e.g. SOLAS, MARPOL).
- Classification is a voluntary system but often required by flag states, insurers, and charterers as proof of seaworthiness.
- Examples include Lloyd’s Register (LR), Det Norske Veritas (DNV), Bureau Veritas (BV), American Bureau of Shipping (ABS).
- A vessel “in class” means it meets all required standards, while “class suspended” means deficiencies exist.
(1 mark for each key point = 6 total.)
(b) Periods between docking surveys for a vessel less than 15 years old (4 marks)
- For vessels under 15 years old, SOLAS and Classification Society rules generally require:
- Two Docking Surveys within each five-year Special Survey cycle.
- These may be carried out as:
- Two dry-dockings (one at about 2.5 years, the other at 5 years), or
- One dry-docking + one in-water survey (subject to approval and vessel suitability).
- Interval between two consecutive dockings must not normally exceed 36 months.
- This ensures continuous monitoring of the vessel’s underwater hull, sea valves, rudder, and propeller.
