Heavy-lift rigging for offshore operations
Offshore & Oil & Gas
Sealinkers supports offshore and oil & gas projects with certified lifting solutions — engineered for harsh, high-consequence environments and backed by our own in-house testing. India’s offshore sector is anchored by decades of production in the Mumbai High basin and a growing base of EPC contractors, platform operators and offshore support vessel fleets — all of whom depend on rigging gear with full traceability and, where a project calls for it, DNV or class-society approval.
Challenges we solve
Extreme weather & salt
Offshore sites face high winds, salt spray and UV. We supply Cortland synthetic slings that resist chemical, UV and abrasion degradation.
Complex heavy lifts
Platform and module installs need precise load control. We supply Straightpoint load cells for real-time monitoring during critical lifts.
Rigorous certification
Offshore work demands documented, traceable gear. Our test house certifies rigging and issues load-test certificates for project sign-off.
DNV-ST-0378 compliance
Offshore lifting appliances and loose gear increasingly need to meet DNV-ST-0378, the DNV standard for offshore lifting equipment, on top of API and ISO requirements. We supply and certify gear against the standard your project specifies.
What we supply
Anchors & Anchor Chain
Offshore mooring chain in Grades R3 to R5, stud and studless, plus the connectors and swivels that go with it — a different product family from ship anchor chain, with its own approvals and test regime.
Synthetic Heavy-Lift Slings
Cortland Plasma HMPE slings — high strength-to-weight, low creep, easy to handle for offshore and subsea heavy lifts.
Load Monitoring & Load Cells
Straightpoint wireless load cells and dynamometers for real-time tension and weight verification during lifts.
Wire Rope Assemblies
High-strength wire rope and slings for offshore rigging, fabricated and certified in-house — Usha Martin rope.
Heavy-Duty Shackles
Alloy bow shackles and connectors for platform and heavy-load connections — genuine Crosby hardware.
Offshore Lifting Appliance Certification
Proof-load, tensile and NDT testing of offshore lifting appliances and loose gear to DNV-ST-0378, API and ISO requirements, witnessed by class where the project requires it.
Standards
- DNV-ST-0378 (offshore lifting equipment)
- API RP 2D (offshore crane operations)
- IRS / class certification
- in-house testing
Frequently asked questions
Do you supply DNV / class-certifiable offshore rigging?
Yes. We supply lifting gear suitable for offshore certification (including DNV-type-approved Straightpoint load cells) and certify assembled rigging through our in-house test house.
Which load cells do you recommend offshore?
We supply Crosby Straightpoint wireless load cells and dynamometers, which give accurate real-time data — including ATEX/IECEx versions for hazardous areas.
Are Cortland slings suitable for subsea and heavy lift?
Yes. Cortland Plasma synthetic slings are widely used in offshore heavy-lift and subsea work for their strength-to-weight and low creep, supplied with documentation.
Can you certify offshore rigging in India?
Yes. Sealinkers runs an in-house test house and proof-load tests rigging from 1 to 1,200 tonnes, issuing certificates for offshore and oil & gas projects.
Do you certify gear to DNV-ST-0378?
Yes. Where a project specifies DNV-ST-0378 for offshore lifting equipment, we test and document gear against that standard, alongside API and ISO requirements as needed.
Can you supply rigging ahead of an EPC hook-up or module-fabrication campaign?
Yes. We work with EPC contractors and fabrication yards to specify and supply certified rigging ahead of a hook-up campaign, so gear and paperwork are ready before the crew mobilises.
