How to Choose Aluminum Profiles for Offshore Helideck Projects: 8 Engineering Checks

2026-09-07

Offshore helicopter operations continue to support energy, marine and remote-infrastructure projects where reliable access is essential. Recent procurement activity in the North Sea illustrates this ongoing demand: EWE has launched a tender for helicopter transport services supporting planned maintenance and repair operations at the Riffgat offshore wind farm, with the contract expected to cover helideck operations for different passenger capacities from April 2027.

For helideck owners, EPC contractors, offshore-wind operators and specialized platform manufacturers, the aluminum profile is only one part of the complete landing-area system. Profile geometry, alloy selection, surface treatment, joining method, inspection and compatibility with the project’s aviation and marine requirements all need to be reviewed together.

CAP 437 is not a universal certification rule for every helideck worldwide. Final design, approval and compliance requirements depend on the project location, aircraft operator, authority having jurisdiction and responsible engineering team.
