Pipe supply vessels

Dynamically positioned deliveries 

Equipped with full DP systems, our fleet of pipe supply vessels (PSVs) perform safe, precise and reliable pipe, equipment and material transfers. Operational in congested and challenging waters, and harsh offshore conditions, they provide a vital link in the project supply chain enhancing the efficiency of our offshore operations.  

Each vessel offers significant pipe intake of up to 3000 tonnes and spacious, adaptable deck areas of 900 m², allowing for modifications to suit specific project needs. Fortress includes a man-riding crane for light offshore lifts, and Alegria features a 1000 m³ MEG storage with nitrogen piping arrangements, optimising material handling.   

Together, Alegria, Felicity and Fortress ensure Allseas’ offshore projects receive reliable, enhancing our capability to execute complex installations worldwide.
