Design and Certification of Lifting Equipment

To ensure that equipment is fit for purpose, local Controlling Documents shall address design, certification, maintenance, and inspection criteria in accordance with a recognized standard and/or manufacturer’s recommendations. The manufacturer or an approved certification body shall issue a certificate or a letter of conformance to appropriate standards (as mentioned in appendix B or national equivalent – most stringent prevail).

Lifting Appliances

The manufacturer shall supply all Lifting Appliances with documentation that defines the permissible operating conditions, design criteria, documentation of testing, maintenance requirements and examination and inspection requirements.

Each Lifting Appliance shall be marked to show:

  • Safe Working Load (SWL);
  • Unique identification number;
  • Date of last certification and/or date of next certification;
  • Color coding (Damen standard or national standard).

Lifting Accessories

All Lifting Accessories shall comply with applicable international standards and industry accepted codes of practice and be marked in the same manner as Lifting Appliances:

  • Safe Working Load (SWL);
  • Unique identification number;
  • Date of last certification and/or date of next certification;
  • Color coding (Damen standard or national standard).

The shipyard should avoid the use of self-engineered lifting devices. When this is unavoidable, the lifting devices shall be designed, manufactured, and tested in compliance with the relevant industry standards. Demonstration of compliance should be retained. All engineered lifting points shall be certified.

Maintenance of Lifting Equipment

The maintenance strategy shall be based on manufacturers’ recommendations, operating experience and integration of preventative and predictive maintenance techniques. Maintenance activities shall include a review of spare part requirements.

Testing of Lifting Equipment

Proof Load Testing

For all new Lifting Equipment proof load testing shall be carried out prior to first use unless a test certificate or letter of conformity is supplied with the equipment. The consequences of failure during testing shall be assessed and controlled.

Where existing Lifting Equipment is significantly altered or a major repair to components in the load path is carried out, a proof load test shall be conducted. Deviation from this recommendation shall be approved as specified in local task descriptions and documented in the equipment records. Test rigs should be used for proof testing of Lifting Accessories (e.g. cranes should not be used for this purpose).

Proof Load testing shall take place at least once every four years, or more when required by the use of the lifting equipment of local regulations.
