Boltight has been at the forefront of hydraulic bolt tensioning for over a decade. Our tensioning tools provide fast, accurate and safe solutions to tighten and loosen multiple bolts simultaneously.

Boltight solutions for Subsea

Our tools are fast, reliable and easy to use - saving diver time and maximizing subsea operations.

Securing bolted connections in subsea environments is a dangerous business. Descending into the depths of the ocean takes time and the lower you go, the more difficult it is to withstand the forces acting upon your body. Visibility decreases drastically, necessitating tools that are simple to use. Communication systems are unreliable, making safety a top priority. Pressure is increasingly difficult to bear, limiting the time you have for maintenance. 

We work closely with the subsea industry to develop solutions that suit your unique requirements. Our bolt tensioners have a proven track record for their reliability, accuracy and safety when operating in the toughest offshore conditions. Our bolt tensioners are in service all over the world, including the North Sea, Nigeria, South East Asia and North America.
