Marine Buoyancy · Modular
HDPE Pipe Floater
Bolt-on floats keeping your pipeline riding on the surface.
Every floating dredge line needs the same thing — reliable, modular buoyancy that doesn't punish the pipe underneath. Our rotomoulded HDPE pipe floaters clamp around the main in matched pairs, delivering the exact reserve buoyancy your project engineer specified.




Key Features
Why field crews specify Heartwork
Reserve buoyancy tuned
Sized in matched pairs for the calculated submerged weight of your loaded pipeline.
Wave & impact tolerant
Rotomoulded HDPE shell shrugs off tow-boat contact and wave-driven collisions.
Tool-less bolt-on
Two-piece design clamps around pipe with stainless bolts — no fusion, no lifting equipment.
UV & salt stabilised
Signal orange stabilised for 8+ years of continuous offshore service.
