Modular subsurface buoyancy

Balmoral subsurface buoyancy at Aberdeen Harbour

Balmoral has developed its range of modular subsurface buoyancy products to include standardised “off-the-shelf” solutions.

Designed to offer a cost effective and rapid response to immediate buoyancy requirements, the new buoys complement the company’s existing range of products suitable for use from 0-3000msw.

These modules incorporate ‘flats’ which provide easier handling and deck storage whilst simultaneously improving robustness.

We believe these are the most user-friendly subsurface buoys on the market.

Modular buoyancy range

Designed for use from 0-3000msw these buoys are used predominantly as suspended moorings or subsea markers. Balmoral modular buoyancy is highly adaptable and can be fitted with a comprehensive range of end fittings.

BOE’s modular buoyancy utilises a range of tough, abrasion resistant core materials contained within a rotational moulded polyethylene shell. Other external finishes are available on request.

Note: All weight in air and buoyancy values are nominal and subject to specific configuration.
