Accessing the Splash Zone


The services OceanTech offers include all types of mechanical tools for underwater use and are remotely operated. This is in addition to the core skills and expertise in the provision of rigging, cleaning, inspection and repair solutions for the Splash Zone.

OceanTech has a range of tools and techniques, ranging from lightweight robotic solutions to more heavy-duty solutions with work class robotic arms. All the tools and techniques are designed to avoid any use of divers, ROVs or support vessels.

Tailored bespoke services


We also provide bespoke services tailored for the decommissioning sector. This expertise is particularly relevant to the pre-engineering and preparation phase of decommissioning, where under-deck structures, caissons, riser, clamps etc. need to be cut and removed prior to the arrival of a heavy-lift vessel.
