Additional Information

The integrated system consists of a tensioner system mounted on a frame with an enclosed 9.3m diameter reel and a movable entry/departure chute.

The reel is fixed within the unit’s frame and does not require separate sea fastening onto deck.

The unit can deploy or retrieve the product both in vertical or horizontal orientation, guided by the pivoting top chute.

The tensioner’s top track is mounted on kingpins so it can pivot to open or close as required by the operator through two hydraulic cylinders.

The tensioner’s bottom track is fixed onto the reeler frame with load cell pins to allow accurate load monitoring.

During operation both the top and bottom tracks are synchronised to deliver the same amount of torque from their respective electric motors.

The unit is supplied with a dedicated electro-hydraulic powerpack.

These specifications apply to a 3inch 15kpsi pipe at 3200m length. System specifications for other pipe length, diameter and design pressure will differ.
