Pipelaying ships are used in subsea infrastructure construction projects to install rigid and flexible pipes and umbilicals in water depths up to 3000 meters. Due to the extreme masses and lengths of the pipes being laid deep onto ocean floors, the reliability and safety of onboard systems is of the utmost importance.
Skeleton Technologies and MJR Power & Automation have cooperated on a first-of-its-kind pipelay extended supply failure ride-through system in one of the largest pipelaying ships in the world, improving the capabilities and safety of the system.
Pipelay Failure Ride-Through System
The vessel pipelay tower has tandem upper and lower tensioners. The port drive system supplies the upper tensioner and various winches located on the back deck. The Starboard drive system supplies the lower tensioner and various items of equipment on the pipelay system. In pipelaying operations, it is essential to rule out any possibility of blackouts during operations and ensure synchronization between the tensioners and the reel. Skeleton's energy storage solution provides immediate back-up power, bridging any gap in power until the main back-up system can respond.
