Service & Support
Exchange and Recertification
A hook (and if applicable, the swivel joint) shall have major service after 5 years. Each hook is delivered with a certificate stating the expiry date. Recertification is a program where the customer sends the hook to us for rehabilitation and re-testing.
During service the complete system will be dismounted and the main bolt will be changed together with any parts that have significant wear & tear.
Henriksen Exchange Program
Most customers use the Henriksen Exchange Program. When a hook nears expiry, the customer orders a refurbished hook from our exchange pool. The exchange hook is invoiced at a discounted rate (generally 30–70% of full price, depending on model). The expired hook must then be returned within 60 days, otherwise full price will be charged.
Finally the system/hook is tested just as if it was new (including the 2,5 x SWL test). The hook/systems we send back genereally appear as brand new. A recertification is usually completed within a couple of weeks, and the serviced hook will be ready and certified for 5 more years of service.
Henriksen Recertification Program
Customers may also return their hook to H. Henriksen, and wait for their same hook to be recertified and returned. This is called the H. Henriksen recertification program. The service and recertification is the same, but H. Henriksen will genereally need 2-3 weeks to complete the service plus transport. Resulting in a boat with no hook for a period of time. The cost of the service is 30 - 70% of full price of a hook, depending on hook model.

Certification Approval & Training
Certification and Technical Approval
Lifting equipment for manned vessels such as FRCs, RIBs, military vessels and MOB boats is subject to strict regulations. All our single point lifting Hooks gets the wheel mark after receiving the proper technical approval. The wheel mark entails that we ourselves approve every hook we manufacture according to procedures and standards that have been approved by Det Norske Veritas (DNV).
Ahead of the approval given from DNV, we perform a 3. party strength calculation. Additionally, DNV witnesses as we carry out the qualification test (destructive). When the test regime and calculations have been approved and accepted, are we issued a certificate from DNV that gives us the right to sell the products with a wheel mark. Every lifting hook we produce is tested to 2,5 times WLL and undergo a thorough qualification test regime prior to delivery.
Please find certificates for your Henriksen Hook on the Certificates site.
User Training
The users should have regular training with the system. This should be regulated in the training plans for the ship or boat. Training is important to prevent accidents.
Yearly Inspection
Yearly, the hook and hook system must be inspected by a trained inspector.
H. Henriksen can provide a course with a trained personnel for single persons or groups, or a 2 hours personal web-based course to educate service personnel.
The scope is to learn the system and to be able to do a qualified inspection of the hook. There shall be a service record on board to document the details and the results of the yearly inspection.
