Lorelay

Pioneering pipelay excellence  

As the world’s first DP pipelay vessel, Lorelay laid the foundation for Allseas’ reputation for innovation and reliability. Dynamic positioning allows precise station-keeping, making it possible to lay pipelines in deep, remote waters with unmatched reliability. This groundbreaking development propelled Allseas into the deepwater market in support of ambitious developers pushing farther offshore and requiring cutting-edge technology to achieve their goals. 

Lorelay has consistently delivered on complex, high-stakes projects, establishing an unmatched track record in both shallow and deepwater pipelaying. Versatile and optimised for laying small- and medium-diameter pipelines of any length, she has set numerous depth records and is the first DP pipelay vessel to execute above-water tie-ins. Her high transit speed, large pipe storage and advanced systems for automated welding and inspection further enhance performance and reliability. 

Equipped for trenching with Allseas’ trencher Digging Donald, and flooding, gauging and testing (FGT) spread for post-lay commissioning activities, Lorelay continues to offer specialist pipelay solutions to clients four decades after her launch.
