Northsea Offshore Technology manufactures lightweight aluminium structures and accommodation projects for the international marine and offshore industry.

Aluminium helidecks for offshore platforms

Northsea Offshore Technology’s patented, maintenance-free, class-certified aluminium helicopter deck is suitable for both onshore and offshore applications. The rigid yet lightweight extruded marine grade aluminium design weighs less than steel equivalents, while exceeding structural integrity standards.

The company provides a complete helideck package with accessories, including pancake, deck plank and girder beam, in addition to the entire aluminium structural support system.

Northsea Offshore Technology specialises in helidecks and modular units for the offshore industry.
All structures are made of lightweight aluminium, which reduces weight, transport time and costs.
Helideck accessories such as lighting, girder beams and deck planks are available.
Northsea Offshore Technology supplies a wide range of packages to accompany its products, including a selection of firefighting equipment.
The company provides a thorough after-sales service.
Northsea Offshore Technology manufactures its solutions in its facility in China.

Its helideck kit is designed for modular on-site assembly and is entirely bolted together so no welding or further on-site fabrication is required. Features include a carefully engineered serrated surface to ensure high-friction co-efficiency on the landing deck, which can be either painted green or left neutral.

All extruded profiles and plates feature marine grade 6xxx or 5xxx serials. The fasteners for aluminium connections are SS316 grade A40-70 or 80.

Applicable projects for helideck include:

  • Rigs: semi-submersible, jack-up, fixed oil
  • Vessels: offshore supply; pipe / cable lay; crane; floating, (production) storage and offloading
  • Barges
  • Cruise ships
  • Various onshore buildings
