Marine Aluminium Helidecks offer Clients:
• Weight Reductions compared to steel (approx. 50-65%)
• Strength (same as mild steel)
• Cost Savings due to minimal maintenance (no rust or painting)
• Fire Safety (Safe Deck®)
• Tailored Solutions
If your project or vessel is weight sensitive a weight reduction compared to steel of approximately 50-65% will be extremely beneficial. The weight saved using aluminium can be used elsewhere, such as storage or accommodation facilities.
Care is taken to calculate our helidecks’ strength to meet Class strength and other requirements. This gives our customers confidence in being delivered a strong quality helideck. Customers who traditionally use steel can be assured that strength requirements are met using aluminium.
Lifecycle cost analysis has shown that savings can be significant if using aluminium.
Considerations for lifecycle cost of steel:
- Offshore manhours
- Painting, treatment and welding materials
- Scrap metal value
Marine Aluminium has developed a fluid drainage system for Helidecks according to NORSOK-C004 requirements. Our Safe Deck® System has been tested and approved in accordance with DNV and ABS regulations.
Safe Deck® is a recessed drainage system for safe collection and discharge of water and any dispersed fuel on the helideck.
The inlet openings provide effective drainage of firewater and dispersed fuel in a safe and controlled manner. The Safe Deck®’s profile shape limits the combustible surface and deprives fire of oxygen.
Tests performed proved that the strength of the aluminium bearing profiles are not affected by a fire. The tests were witnessed and approved by representatives from ABS, DNV, Lloyds and several international oil companies.
Experience in designing and manufacturing helidecks approved for the following:
DNV, ABS, Lloyds Register, BV, Rina,
NORSOK, CAP 437, USCG, API, SOLAS, ICAO, IMO, BSL D-5-1, BL 3-5, MNDPC, TCA, TCM, ICA, AMSA. Eurocode 9.
