HDPE – High Density Polyethylene

The Genius of Workboat Construction

HDPE (High Density Polyethylene) use in the marine industry is not new. It has been a project solution constructing harbour and port security barriers, heavy duty dockside fender systems to residential docks and pontoons for over 3 decades. Used extensively across the global aquaculture industry in extreme weather and sea conditions it surpasses performance expectations of meeting the arduous tasks of keeping crew safe while servicing offshore installations.

Cost Savings and Reduced Maintenance

  • Impact resistant – extremely robust
  • Intact buoyancy – lighter than water
  • No anti-fouling – highly resistant to corrosion chemicals and marine growth
  • No anodes – excellent insulator
  • No moisture absorption
  • Long-lasting – excess 20 years
  • Minimal heat transfer – copper transfers heat 2700 times more than HDPE
  • Elasticity durability – a high tensile strength that can withstand fatigue and surges
  • Long-lasting – well maintained >20 years
  • Weather-resistance – climate transferable
  • Arctic to the tropics – frozen water will not crack HDPE and carbon black provides UV resistance
  • Recyclable – it could be your next milk jug!

A Modern Material for a Modern Workboat

Indestructible and Robust

When the benefits of HDPE are brought together it is clear there are significant advantages that outweigh GRP, aluminium and steel as a construction material. Designing out the traditional RCB ‘inflatable tubes’ increases deck space by 50%… how many GRP, RCBs or Aluminium boats can be dragged along the rocky beach into the water without specific hull reinforcement?

Outstanding Adaptability and Reliability

HDPE constructs an almost indestructible and unsinkable functional workboat. It delivers tremendous strength, intact buoyancy and a reliable stable working platform. Our no nonsense approach to the design and build reduces construction times – an average of 4 weeks for a 8m bare boat.
