Subsea applications: bolt tensioning and flange pulling tools
Tentec, the manufacturer and supplier of bolt tensioning Equipment, has launched the Optimus 6 series of subsea bolt tensioning and flange pulling tools.
The Optimus 6 family comprises bolt tensioning tools, a flange pulling system (FPS), subsea hose reels and pumps, as well as the unique Optimus Bolt Load Software. Tentec’s equipment has been used in the North Sea since 1991 and Optimus 6 continues the tradition of proven reliability and safety. Designed to withstand the demanding requirements of divers working in these harsh conditions, this new range incorporates many features.
To minimise maintenance and prevent early corrosion, the bolt tensioning tools and FPS, as well as the hose reels are all manufactured in high grade, anti corrosive stainless steel.
For divers, the Optimus 6 bolt tensioning tools with quick acting split reaction nuts have been developed for ease of use, as well as reducing diver fatigue, while increasing productivity. Its ergonomic
design incorporating lifting straps for easy handling and non-slip tool surface combines with its compact design to maximise tool suitability. Designed with highest pulling force of all systems on the
market, the FPS cylinders can each pull with a force up to 259kN and up to 4 cylinders can be used together to achieve a total pulling force of 1036kN. The system also features automatic collet release that means there is no need for diver intervention between each pulling stroke.
Two hose reels are available in the series. A compact model, measuring only 885mm x 933mm and a standard reel at 535mm x 1321mm. Both reels have capacity for 600m of bolt tensioning flexible hose or 300m of twin hose. With an integrated high pressure quick connection coupling and a locking facility that allows the reel to be unattended during pressurisation, these subsea hose reels ensure fast, efficient and safe operations.
Finally, Tentec has developed a bolted joint software package that provides all necessary documentation for topside and subsea bolt tensioning projects. The software can rapidly produce both individual flange data sheets and project summary documents.
