About Us

Ultrabeam Limited was established in early 2018 by Gabriel Walton and Andy McLeay who share over 45 years of combined experience in coastal and offshore survey industry.

The company was formed to deliver high-quality hydrographic and geophysical services to a wide range of clients, from ports and harbours to utilities including offshore renewable energy, oil & gas and public sector marine industries.

Accurate hydrographic surveys are vital for the maintenance of marine assets such as harbours, bridges, offshore installations and oil and gas platforms. From Day One, the company has focused on a specific and revolutionary method for conducting these surveys, by using unmanned survey vessels (USVs) that it has designed and built itself. Using USVs makes carrying out these surveys much more efficient and also safer, particularly in hazardous conditions.

Ultrabeam has combined this innovative approach with cutting edge data processing and visualisation methods to provide deliverables which outperform anything currently available in the marine industry.


Andrew McLeay

Gabriel Walton

Technical Director

With nearly 15 years experience in the survey industry, Gabe brings his technical flair and operational steady hand to Ultrabeam.

Ultrabeam provide an unparalleled level of accuracy and detail through the use of specialist, highly innovative survey tools and techniques. The Ultrabeam difference is in our data, supported by our many years of shallow and deep water survey experience. We see our work as a distinct specialism and, rather than overlapping from a core land survey company or being an appendage to a large offshore survey company, Ultrabeam is entirely focussed on ultra high resolution marine asset survey and delivery of outstanding high-quality survey data.

We have developed our own unmanned surface vessel (USV), which has been designed to enhance slow speed and static data acquisition optimising data density and coverage by enabling complete control of transducer alignment during survey. The USV is a robust 3.2m x 1.7m dynamically positioned shallow draught asymmetric catamaran design named Ultra-2. With two operating modes, Ultra-2 can be used for static data using dynamic positioning, or can survey at speeds of up to 8 knots for wide area survey.
