Offshore and Renewables » Modular Mooring Buoys


Manuplas offer through its parent company Advanced Insulation, a range of' modular buoyancy solutions to provide support for mooring from surface to 3000MSW for suspended mooring, equipment installation and general offshore operations.  Customisation is available to suit the particular requirements with three standard sizes available in multiple configurations:

  • MINI (1750mm x 1750mm Cross-section)
  • MIDI (2350mm x 2350mm Cross-section)
  • MAXI (3000mm x 3000mm Cross-section)

Individual buoyancy elements or complete buoys including central structural steelwork assemblies are also available and can be supplied with a variety of handling options.


  • The flotation core component maybe syntactic foam for deepwater deployment or more lightweight expanded polymer foams to maximise buoyancy yield in shallow waters, and are cast with a robust impact resistant rotationally moulded external shell.
  • Surface and syntactic foam core versions can be easily repaired on site or by return to Manuplas.
  • Additional impact protection for extreme service environments is additionally available.


  • Modular design, 1-40T of nett buoyancy
  • MINI, MIDI AND MAXI industry standard sizes
  • Compartmentalised design for greater protection
  • Flat sides to facilitate stable storage and tight operational configurations
  • Easily adjustable to meet specific buoyancy requirement
  • Interlocking design to eliminate rotation during operation
  • Modular design allows easy buoyancy element change-out in damage event
  • Ease of repair
  • Central structural steelwork
  • Lightweight foam flotation cores
