One-stop excavation and support

We draw on the subsea technology and expertise from across the Marin Group to offer a one-stop service that meets the widest range of excavation challenges in inshore and shallow depths of between 3 and 40 metres.

At our disposal are Marin’s Evo Excavation System core tools  including the Evo 150 and Evo V-Jet configuration  as well as jet sled trenching delivered by Marin Group specialist Samson Marin and the Vortex Subsea Excavation System range of diver hand-held and ROV-mounted services from Marin Vortex.

Through Marin JMS we provide customised container and module supply for all inshore and shallow water operations, and our alliances with Fugro-Rovtech, Ecosse Subsea Systems, and Cardox International give us access to further specialised ROV, excavation, trenching and cutting options.
