Higly efficient S-lay systems

S-Lay systems are used to lay rigid pipe with diameters up to 70”. Pipe joints are welded together onboard the vessel in a horizontal production line and the pipe is guided to the seabed by means of a stinger attached to the stern of the vessel or barge.

We design and deliver complete SAS® S-Lay pipelaying systems for shallow to ultra-deep water.

Features

high quality systems with high uptime guaranteed
robust and maintenance-friendly design
fully automatic tension transfer between tensioner and winch
sophisticated control system developed in-house
both horizontal and vertical designs available.

Our pipe laying systems include a sophisticated control interface that enables safe and efficient operation. By creating autonomous pipe movements throughout the system the amount of people on board can be drastically reduced. By using state of the art pipe tracking methods we are able to register and log the pipestring exact assembly sequence and composition.

Large systems incorporate advanced pipe handling equipment such as line up tools, pipe elevators, transfer vehicles, overhead pipe grabbers. Each with sophisticated controls to allow synchronized movement of up to hex join pipe lengths.

An S-Lay system normally comprises 2-track tensioners, an A&R (traction) winch system, pipe handling equipment and a stinger.
