16.5m Spar Navigation Buoys for Marine Terminal

ONA were recently awarded  design and fabrication support for 4 x 16.5m steel navigation buoys for use at an offshore marine terminal in Western Australia. The buoys will be installed by an installation contractor and moored in depths of 20-21m using clump weights.

Each buoy is fitted with a flashing solar Sealite type lights and an appropriate day shape. The design is based on existing spar buoys in the area but has been engineered to facilitate easy transport and installation. The buoy is fitted with day shapes in accordance with the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA). ONA Marine endeavours to conform to all of the Recommendations, Guidelines and other documentation offered by IALA.

ONA Marine provides turnkey design to design and build packages. All ONA Marine designs are licensed to ensure the highest quality on build and construction. All ONA Marine supply packages include the following tiers of design and build:

  • Tier 1 – Licensed Design and Drawing
  • Tier 2 – Licensed Design Drawing, Shop and Production Detailing (ITP, MDR)
  • Tier 3 – Licensed Design and Construction

Tier 2 and 3 offer the best guarantee of build quality and client assurance.  All designs come with Class type approval certificates to reduce the need for costly design verification by 3rd and 4th parties. Additional design and calculation packages are provided on request.
