Survey vessels

Trusted partner with experienced crew

Our benthic sampling surveys are designed to identify biological communities in subtidal habitats and classify marine biotopes. These surveys are essential for projects in inshore or offshore waters, particularly when activities may impact designated marine conservation areas, such as Special Areas of Conservation (SACs) or Special Protection Areas (SPAs).

ICCB also offers geophysical survey services to provide detailed insights into seabed and sub-seabed conditions. Using state-of-the-art technology, our team conducts surveys that capture high-resolution data on sediment composition, underwater structures, and potential obstructions. These surveys are critical for infrastructure projects such as cable installations, pipeline routes, and renewable energy developments, as well as for understanding the geological context of marine environments.

Dive support

Capable craft, professional crew

Read more +

For professional diving projects, a diving support vessel is a ship that serves as a floating base. The fundamental prerequisites are the capacity to maintain station precisely and consistently during a diving operation, frequently near drilling or production platforms; the ability for positioning to deteriorate gradually enough in failing conditions to allow divers to be recovered without undue risk; and the ability to carry the support equipment required for the type of diving to be employed.
