SUSTAINABILITY
Sustainability is not simply a material attribute; it is a design philosophy. A truly sustainable helideck must be evaluated across its entire lifecycle, balancing environmental impact, operational efficiency, durability, maintenance demands, and end-of-life recoverability to maximise long-term value.
THE APPROACH
Aluminium helidecks offer several potential sustainability advantages, particularly for offshore platforms, vessels and rooftop applications where weight, corrosion resistance and long-term maintenance are important considerations.
The actual environmental impact of aluminium depends on the source of the material, the proportion of recycled content, the energy used during production, manufacturing efficiency, transportation distances, the service life of the structure and end-of-life recovery.
For that reason we treat aluminium as part of a broader lifecycle strategy, rather than treating recyclability alone as proof of sustainability.
LOWER STRUCTURAL WEIGHT
Aluminium has a significantly lower density than steel. An aluminium helideck can therefore reduce the overall weight imposed on the supporting structure.
Depending on the project, this may reduce supporting steelwork and foundation requirements, lower transportation and lifting loads, and allow easier modularisation and installation. It also gives greater flexibility when retrofitting existing structures.
The benefit should be assessed as part of the complete structural design, as reductions in helideck weight may also reduce the materials and resources required elsewhere in the project.
LIFECYCLE PERFORMANCE
Corrosion Resistance
Aluminium naturally forms a protective oxide layer that resists atmospheric corrosion, making it well suited to marine and offshore environments. Primary deck structures generally require no extensive protective coating system, reducing paint and coating consumption · Abrasive blasting · Solvent and chemical use · Maintenance-related waste · Offshore maintenance hours · Operational disruption
Long Service Life
A sustainable structure should remain functional, safe and maintainable for as long as reasonably possible. Corrosion resistance and durability support a long operational life where the deck is correctly designed for fatigue, drainage, material compatibility and galvanic corrosion.
Recyclability
Aluminium can be recycled repeatedly without losing its fundamental material properties. At the end of a helideck’s service life, a substantial proportion of the aluminium structure may be recovered and returned to the material supply chain.
Transport & Installation
Lower weight allows larger sections to be prefabricated before delivery to site, reducing site assembly work · Offshore installation duration · Heavy lifting requirements · Hot work at the final installation location · Construction waste · Rework and material handling
PASSIVE FIRE SAFETY
Our aluminium helidecks can be integrated with passive fire-retarding deck technology designed to rapidly drain burning fuel away from the landing surface.
Combined with an appropriately designed water-based DIFFS, this approach eliminates the need for foam-based firefighting agents. That removes storage, testing and replacement requirements for firefighting foam, lowers the risk of foam discharge into the environment, and reduces maintenance cost over the life of the system.
All firefighting arrangements must be designed and approved in accordance with the relevant aviation standards, authority requirements and project-specific risk assessment.
A WHOLE-LIFE APPROACH
Sustainable helideck design should balance aviation safety, structural efficiency, fire performance and material durability against maintenance requirements, operational reliability, environmental impact and end-of-life recoverability.
The most sustainable solution is not necessarily the one with the lowest initial material footprint. It is the solution that provides the required safety and performance while minimising resource use, maintenance and waste throughout its complete service life.
Good design practice, including the isolation of dissimilar metals, appropriate fastening systems and effective water drainage, is essential to achieving the intended lifecycle performance.
