The procedures carried out by a Classification Society for a new vessel to be built to class rules
The process for a new vessel to be built to class rules and receive a class certificate involves extensive collaboration between the shipbuilder, the shipowner, and the Classification Society. Here’s a general outline of the procedures:
1. Plan Approval and Design Review:
- The shipbuilder submits detailed plans and specifications of the vessel to the Classification Society for review and approval.
- The Classification Society assesses the design for compliance with its rules and relevant international conventions like SOLAS and MARPOL.
- Feedback and modifications may be required to ensure the design meets all necessary standards.
2. Construction Supervision:
- Throughout the construction process, Classification Society surveyors conduct regular inspections and surveys to verify that the vessel is being built according to the approved plans and class rules.
- This includes inspections of materials, welding, structural components, machinery installations, and safety systems.
3. Testing and Trials:
- Once construction is complete, the vessel undergoes various tests and trials, such as inclining tests for stability, sea trials for performance, and safety equipment tests.
- Classification Society surveyors witness these tests and trials to confirm compliance with requirements.
4. Final Survey and Certification:
- A final comprehensive survey is conducted by the Classification Society to assess the completed vessel’s overall condition and adherence to all applicable rules and regulations.
- If the vessel is found to be satisfactory, the Classification Society issues a Certificate of Class, confirming that it has been built to class and is fit for its intended service.
Key points to note:
- Continuous Engagement: The Classification Society is involved throughout the entire shipbuilding process, from plan approval to final certification, ensuring continuous oversight and compliance.
- Documentation and Record Keeping: Detailed documentation of all surveys, inspections, tests, and corrective actions is maintained and submitted to the Classification Society.
- Corrective Actions: If any non-conformities or deficiencies are identified during the surveys, the shipbuilder must rectify them to the satisfaction of the Classification Society before the class certificate is issued.
- Class Notation: The issued Certificate of Class will include a class notation, indicating the vessel’s type, construction quality, and intended service.
Benefits of Building to Class:
- Assurance of Quality and Safety: It assures that the vessel meets high standards of safety, structural integrity, and environmental performance.
- Facilitates Insurance and Financing: A classed vessel is more likely to secure insurance coverage and financing at favorable terms.
- Enhances Marketability: Classification increases the vessel’s marketability and resale value.
- Access to Ports and Waterways: Many ports and waterways require vessels to have a valid class certificate for entry and operation.
- Compliance with Regulations: It ensures compliance with various international conventions and national regulations, reducing the risk of detentions or penalties.
In conclusion, building a new vessel to class rules and obtaining a class certificate is a complex and rigorous process that involves close collaboration between the shipbuilder, shipowner, and the Classification Society. However, the benefits in terms of safety, compliance, and marketability make it a worthwhile investment for ensuring the successful operation of the vessel throughout its lifespan.
