Subsea Tensioners
A specially designed range of Bolt Tensioning equipment to suit the demanding requirements of divers operating in harsh subsea environments.
This range of subsea bolt tensioning tools brings a new generation of bolting solutions.
Comprising just 8 bolt tensioning tools, this series is capable of tensioning most standard flanges. They are made from high strength stainless steel which greatly reduces maintenance work to a minimum after subsea use.
The new range of subsea Bolt Tensioning tools have many unique features:
- Manufactured from high strength stainless steel minimises maintenance
- 30mm ram stroke available on all models
- High load capacities to satisfy API 17D/SV - 10000 rating Flanges
- Quick acting split nut available on all models
- Non slip tool surface for easy diver handling
- Fitted with lifting straps for easy diver handling
- High quality reliable seals
- Twin hydraulic connections for simple hose assembly
The most efficient and rapid method of bolt tensioning a flange is 100% simultaneous tensioning. Every bolt is simultaneously tensioned assuring an evenly distributed bolt load across the gasket. The Subsea bolt tensioning tools are fitted with twin hydraulic connections making the hose configuration extremely simple and rapid.
