Certified slings for offshore containers – why they’re essential

Lifting operations in the offshore industry place huge demands on both equipment and documentation. A critical link in the safety chain is the sling that connects the container to the crane – which is exactly why certification and proper use are so important.

At Specialcontainer, we often hear from companies with questions about approvals, lifespan, and traceability when it comes to offshore slings. Many reach out in urgent situations, where the project is already planned but either the right lifting gear isn’t on site – or no longer meets the requirements.

That’s why we keep a range of DNV 2.7-1 certified slings for offshore containers in stock at our Esbjerg depot. We offer both sales and rentals, depending on your project’s duration and needs. All our slings are clearly marked with their WLL (Working Load Limit), and full documentation is provided on delivery.

DNV 2.7-1 is the current standard for offshore containers and related lifting equipment. It sets out requirements for strength, marking, testing, and traceability – and compliance isn’t just a technical box-tick; it’s a prerequisite for safety and insurance in offshore environments.

All slings wear over time, which is why they must be inspected at least every six months. For particularly demanding conditions, checks should be carried out even more often.

Companies working offshore face growing pressure to document safety across the entire supply chain. Choosing the right type of sling – whether chain or wire – along with proper storage, use, and inspection, is a key part of this process.
