Project Background
The project (around 900 MW) is the second phase of a 1.6 GW offshore wind cluster in the German North Sea. In late March 2026, Germany's Federal Maritime and Hydrographic Agency (BSH) granted planning permission for the phase, allowing construction to move ahead. The monopile foundations, each weighing hundreds of metric tons, demand lifting equipment that combines exceptional strength with corrosion resistance in harsh offshore conditions.
Anonymized application example. Client and EPC names are withheld from this public summary; the configuration and quantities below are those supplied. Buyers evaluating a similar scope should still issue their own lift plan and request the documentation set their project requires.
The Solution
The pre-shipment fastening of 18 sets of monopiles specified HMPE eye-and-eye round slings with a working load limit (WLL) of 40 t and a safety factor of 7:1 (MBS 280 t), with below-1% elongation under load. liftrue supplied 72 slings in two bearing lengths (36 pieces of 20.0 m and 36 pieces of 22.76 m) for the lifting and securing of the monopiles before shipment. The non-corrosive, low-stretch properties of HMPE make these slings well suited to prolonged service in marine environments. For a complete specification and procurement framework for offshore lifting, see HMPE Sling Procurement Guide: 9 Things to Verify Before You Order.
Every sling was individually proof-load tested and certified before delivery, and full traceability documentation was provided with the shipment.
- What this case demonstrates: the supplied configuration — 72 eye-and-eye HMPE round slings, WLL 40 t, 7:1 design factor, two bearing lengths, sub-1% working-load elongation — can be documented and delivered as a complete set for a large monopile pre-shipment scope.
- What it does not establish: it is not a type approval for every HMPE sling, a substitute for the project lift plan, or evidence that the same configuration suits a different monopile, crane or sea state. Those decisions remain with the owner/EPC and the applicable sling standard.
