National Oilwell Varco provides pipelay systems for rigid and flexible pipes, tube & hose umbilicals, power cables and other products. Each system can be designed specifically for the product or vessel.

Pipelay systems can be J-Lay utilizing a ramp or S-Lay with a stinger, and the product can be stored on a reel, in a carousel or as lengths on the deck.

The ramp is designed to fleet over the width of the reel allowing product to be spooled on/off accurately.

The ramp can operate from 20 - 90° allowing product to be laid in both shallow and deep water.

The ramp and reel are modular and can be lifted to/from the vessel in a single lift allowing the complete system to be mobbed/de-mobbed within 48 hours.

The system is shown spooling 8"NB pipe on to the reel.
