Pipelay Systems supplies a range of 2-track, 3-track and 4-track tensioners for use in both horizontal and vertical configurations for handling rigid pipe, flexible flowlines and risers, umbilicals and power cable. The tensioners can be used in land based factory applications or in offshore lay operations.
Tensioners consist of caterpillar tracks mounted in a frame and are used to support the product weight whether laying to the seabed or moving product in a factory. The tracks are moved to and from the product by hydraulic cylinders which monitor the grip force and provide fail safe clamping in the event of a power failure. The frame can be designed to open to assist with handling product into or out of the tensioner depending on the application and mounting arrangement.
Pipelay Systems tensioners can be supplied with either electric or hydraulic drives and a control system to suit the drive type.
