Slings are flexible connectors used to lift and move heavy offshore containers and equipment. They link containers to cranes or lifting gear using certified points called pad eyes. In offshore settings, safety and reliability are critical. Slings must meet strict standards to guarantee secure handling and avoid accidents. At Al Basata, we use slings that comply with DNV 2.7‑1 requirements to ensure safe offshore lifting.
What Are Slings?
Slings are strong loops made of chain, wire rope, or synthetic material that wrap around a load and connect to lifting gear. Offshore slings are built for tough environments – resistant to saltwater, weather, and heavy wear. They come with unique ID tags and are tested and certified to ensure they can carry the required weight safely.
DNV 2.7‑1 Sling Standards
The DNV 2.7‑1 standard defines rigorous rules for offshore slings. It demands high-strength materials (like alloy steel), corrosion resistance, and detailed testing. Each sling undergoes static and dynamic load tests, as well as inspections for cracks or defects. Only slings that pass these tests earn DNV certification.
Why DNV-Certified Slings Are Essential
- Safety: Offshore lifting involves unpredictable waves and vessel motion. DNV slings are tested for these conditions, reducing risks during lifts.
- Durability: Made of premium alloy steel with corrosion protection, these slings last longer and perform reliably in harsh marine environments.
- Compliance: Many offshore clients and authorities require DNV-certified equipment. Using non-certified slings can lead to regulatory issues or accidents.
- Versatility: DNV slings are available in single-leg to multi-leg configurations, with varying load capacities suited to diverse lifting needs.
Types of Slings Used Offshore
- Chain slings: Made of welded alloy steel links for maximum strength.
- Wire rope slings: Flexible and lighter, with thimbles and master links for secure connections. Suitable for dynamic loads.
- Synthetic slings: Lightweight and non‑conductive. Used where metal might spark or corrode, though less common offshore.
Each type can be built into sling assemblies with 1 to 4 legs, depending on how load needs to be supported.
Testing and Certification Process
Offshore slings get certified through a combination of design evaluation, manufacturing audits, and physical testing. Each batch undergoes sample testing: load tests, weld inspections, and verification of markings and ID tags. This careful process ensures traceability and reliability throughout the sling’s working life.
How Slings Work With Offshore Containers
Slings connect to pad eyes – reinforced lifting points installed on DNV-certified offshore containers. Pad eyes must be precisely located and tested to safely lift containers. When combined with certified slings, they form a lifting system that meets safety and performance standards.
Benefits in Real Operations
Using DNV-approved slings offers real advantages:
- Reduced downtime due to fewer equipment failures.
- Lower maintenance costs thanks to higher durability.
- Improved trust from regulators and clients.
- Safer handling even in rough sea conditions.
For offshore teams, the right slings can mean smoother, safer operations.
