Sandpiper  is a flat-bottom, anchored barge for shallow water offshore construction activities, purchased by Allseas in 2022 and upgraded for pipelaying in 2022/23. Sandpiper  is equipped with a 10-point mooring system, pipelay equipment suitable for laying pipe up to of 60 inches in diameter and a piggyback firing line for 6.50 inch diameter pipe. The shallow-water pipelay barge  is also fitted with a davit system that enables her to perform ‘mid-line’ tie-ins and a 800 t crane for construction work.

Sandpiper  operates worldwide, primarily in shallow water areas, both in support of Allseas’ pipelayers and for independent contracting. She can lay pipes up to a water depth of 150 m. Deeper water projects are possible with modifications depending on the projects specifics.

Following extensive pipelay and positioning trials off Johor, Malaysia, Sandpiper  successfully executed her first commercial project in mid-2024.
