Pushing the
boundaries of deep
sea construction

This vehicle was designed to track underwater cable for purpose of on-shore, nearshore and offshore (up to 500m water depth) cable burial assessment.

To extend the life of an offshore service crane, we evaluated loading / usage detail, then designed an in-situ upgrade.

We produced 3D model, fabrication drawing and flat pattern to fabricate a bellmouth. The item is fitted at entrance to HDD cable duct to allow the pull-in of a subsea power cable.

We produced 3D models and fabrication drawings for a Roller Quadrant to enable the installation of offshore power and telecommunications cables. The structure was designed in accordance with relevant standards including DNV-ST-0378, EN 13001 and EN 1993.

Based on a concept proposal, we produced a complete design package (3D model, fabrication drawings and engineering calculations) to enable our client to build a subsea plough. The machine is designed for the simultaneous lay and burial of power and telecommunications cable in shallow and deep water applications.

As part of a survey campaign, we were tasked with designing a survey pole which could be deployed through the vessel moonpool. The solution was a retrievable USBL survey pole, which when deployed was clamped firmly against the vessel structure to minimise vibration / sensor inaccuracy.

Our client required a means to increase crane reach at Quayside, for loading heavy items of cargo onto ships. The load bearing capacity of ground was limited, so we designed a load-distributing steel structure which would allow the crane to be positioned closer to quayside edge.
