Benefits of this service for your operations

For energy

Trying out new equipment, rehearsing new operational procedures and getting your team comfortable with the technology being used, helps identify problems and reduce risk before heading offshore to doing it for real.

For defence

The success of your underwater mission relies on technology and personal operating in synchronicity. Our vessels provide the perfect platform to practice and make perfect in a controlled environment.

For science

You’ve worked hard to secure research vessel time so a vessel charter with us ahead of your cruise can simulate different environments, data logging regimes and harvesting methods.


We have decades of combined experience operating vessels and testing equipment in the waters around Plymouth and beyond. We have intimate knowledge of the rules and regulations affecting marine operations close to the local naval bases, and we know all the best places to test equipment. Whether you need shallow water, open water away from recreational craft to run autonomous surface vessels, or interesting wrecks to evaluate the capabilities of side-scan sonars, we know where to take you.

Technology integration
In support of our own activities within energy, defence and science have extensive experience integrating third-party surface and subsea technologies – and even land-based position reference systems. This has enabled us to develop trials plans and procedures to accommodate non-specific Sonardyne equipment, such as surface navigation equipment,
towfish, uncrewed surface vehicles and seafloor sensors.
We can tailor your charter to your precise needs, assist with planning, coordinate the logistics and manage your safety.

Working with you
Mobilising equipment and personnel to undertake operations on the water is expensive, time consuming and not without risk. That’s why when you charter one of our Plymouth-based survey vessels or facilities, you get more than just a boat or floating classroom. You get the knowledge and experience of our marine engineers and qualified local skippers who are fully committed to ensuring your charter with us is a complete success and meets all of your objectives.
