Dynamic Power
Linear Pipe Tensioner


Quality Crafted in PDI’s full Service Design and Manufacturing Center located within Stennis Space Center Mississippi.

50 KIP, 80 KIP, 100 KIP and 200 KIP PIPE TENSIONERS can be designed, engineered and manufactured to Clients performance specifications.

Pipe lay track tensioner designs date back to the late 1960s when track machines first started replacing the original wheel designs. Tensioners are the key element of pipe lay systems and are used onboard pipe lay vessels to keep tension on the pipeline while it is being lowered onto the seabed.

PDI designed, engineered and manufactured tensioner products offer significant improvements in productivity and safety while achieving maximum work flow efficiency. PDI Tensioners are custom built to our client’s needs and performance specifications.

Track tensioners have two vertically or horizontally opposed tracks that squeeze the pipe to generate the necessary traction for linear pull while achieving an equal circumferential squeeze on the pipe. PDI tensioners employ Electrical - Hydraulic power with PD controller by which the tension in the pipe can be controlled even when the vessel is subject to motions.
