Hydraulic tensioners for subsea applications 14 October 2024

TensionPro has developed a range of highly versatile and reliable hydraulic tensioners, optimised for subsea applications in the offshore oil and gas industry. 

The new SUB series is ideal for tightening Norsok/SPO compact flanges, as well as all common sized ANSI, ASME and API flanges. 

An ergonomic design features a one piece body, anti-slip tool surface, contoured ‘grip’ reaction nuts and a high-vis finish – making it easy for divers to use the tools subsea. A 30mm piston stroke also ensures each bolt tightening operation can be completed in one hit, without having to return the tool to the surface to reset the piston.

Customers can choose between solid or split reaction nut options to suit their application and budget. Both are interchangeable on the SUB series, providing complete flexibility. Split reaction nuts offer speed of use for some applications, while solid reaction nuts provide a fail safe operation for applications with large or unknown bolt misalignment. 

The series’ all stainless steel construction ensures long life performance and guarantees simple and efficient maintenance. Pressure tested and with CE Marking, the SUB series is supplied with detailed operating and safety manuals. Special one off designs are available for any thread size, load and diameter requirements. Ancillary subsea equipment, including pumps, hose reels and downline can also be supplied from stock.
