Tog Mor

Tog Mor  is a flat-bottom, anchored barge for shallow water offshore construction activities, purchased by Allseas in 1997 and converted for pipelaying in 2001/02. Tog Mor  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. Tog Mor  is also fitted with a davit system that enables her to perform midpoint tie-ins and a 300 t crane for construction work.

Tog Mor  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 without modification; deeper water projects are possible with modification to her winches and stinger.
