J-Lay systems for diameters up to 36”

We offer fully integrated vessels, or standalone equipment, according to your wishes. Since the vessel is not required to return to port to resupply, they are often deployed for laying rigid pipe lines in deeper water and remote locations. We have a track record of J-Lay systems for rigid pipes of diameters up to 36”.

Why choose our J-Lay towers?

We work in close collaboration with you to establish the main drivers for your mission.
The layouts of multi-joint pipe facility are designed efficiently, to minimise personnel required to operate.
We provide a patented compact lay tower, designed to minimise impact on vessel stability.
We offer fully integrated vessel as well as standalone equipment, according to your wishes.

Great examples of J-Lay projects

Technical details

Pipe joints of 12m are pre-assembled into groups of four (quad) or six (hex) in a multi-joint facility, before being upended into the tower and deployed to the sea bed. End terminations and manifolds can be attached to the pipe line using the dedicated handling system, and lowered to the sea bed.
