Navigation buoys

Fendercare Marine's navigation buoys are cost-effective, reliable and highly visible, offering long-term, dependable marks for a wide range of offshore applications.

Made from UV stabilised polyethylene, our range of navigation buoys are protected from the long-term degrading effects of naturally occurring radiation. Rotationally moulded for a seamless finish, these essentially stress-free one-piece navigational aids provide increased life functionality at lower prices. 

Virtually maintenance free navigation buoys:

Requiring virtually no maintenance due to the manufacturing process, they have a life-expectancy of up to 20 years.

Where applicable, buoys are available with a choice of stainless or galvanised steel, and unique foam sandwich construction techniques offer exceptionally high strength to weight ratio.

Guardian navigation buoy

Value: The most cost effective due to low upfront outlay and virtually no maintenance expense.

Weather: Guardian buoys are currently withstanding cyclonic/hurricane conditions in locations such as the Bass Straight, Gulf of Mexico and Northern Australia.

Flexibility: Adaptable design enabling customised applications.

Science: Soft riding performance suits scientific instruments/data collection and telemetry delivery.

Re-deployment: Adjustable ballasting system means multiple locations for the same buoy.

GRP minor light towers

Fendercare Marine manufacture a range of minor light towers that are constructed using modular sections to enable easy transportation and assembly at remote locations.

Fendercare Marine's minor light towers have the following features:

  • Modular construction manufactured with a UV stabilised isophthalic gelcoat and resin, at a minimum thickness of 8mm, requiring little maintenance
  • A range of tower heights available up to 15m
  • The towers are locally reinforced by way of the flanges to produce a design of immense strength, allowing them to withstand gale force winds
  • Access to the door section is via an external ladder. The ladder is removable to minimise theft or vandalism. Access to the lantern is via an internal ladder at the top. The top platform is fitted with guard rails to enable safe access to the lantern for maintenance purposes
  • The towers can be fitted with stainless steel frames to support solar panels
  • Each tower is supplied complete with lifting davit kit for on-site assembly
  • The batteries can be stowed either at door level or at ground level within the cone section
  • Colours are in accordance with IALA marking standards towers have been certified to withstand winds of up to 56m per second (125mph)
  • A comprehensive range of lighting systems are available

Lite and super lite buoys

Whether configured as navigational marks in accordance with IALA guidelines or fitted out as databuoys, the largest buoys Fendercare Marine supplies offer outstanding durability and stability and are in service in some of the world's most challenging environments.

Our lite and super lite buoys are fully modular and the superstructure is engineered to both minimise windage and to accept large equipment packages. The flexibility of our technology allows us to adopt a ‘blank page’ approach with users who are looking to achieve a step change in the efficiency of their buoy operations or to incorporate very specific design features.

Seamless buoys

Configured for use with new-generation self-contained lanterns, Fendercare Marine's seamless range of navigation and container buoys offer the same self-fendering construction as its other buoys but at lower price levels due to the single-piece construction, simplified superstructure and optimisation for shipping.

The hulls of the seamless navigation buoys are lightweight and self-fendering, yet extremely durable and virtually unsinkable. They come as standard with a non-slip deck with one-piece construction integrated into the buoy design. Manufactured from a core of thermolaminated closed-cell polyethylene foam encapsulated in a self-colour tough yet flexible polyurethane elastomer skin. The buoys are also configured to take a variety of self-contained LED light systems.

Seamless buoy general specifications:

  • Baffle tail configuration complete with forklift slots to aid quayside handling
  • One-piece construction integrated into the buoy design
  • Supplied with both bridle and single point mooring eyes
