About us

H2O Surveys Limited was set up by James Williams in 2004 to support a growing demand in the ‘multibeam’ market by providing specialist swathe bathymetry personnel to the global marine survey industry.

Having successfully completed survey contracts in the USA, UK, Europe and the Far East, James formed an alliance with Roger Stapleton and Ted Andrews from Transition Zone Technology and began trading as Swathe Services.

A GeoSwath Plus swathe bathymetry system was acquired and the company began offering equipment rental, as well as, experienced hydrographic support. Swathe Services rapidly expanded throughout the following two years and increased demand resulted in the addition of two more GeoSwath Plus systems along with extra processing licences for GeoSwath and GeoTexture.

Swathe Services (Australia) Pty Ltd was set up in Adelaide at the start of 2008 and rapidly grew to cater for the increased demand for support of the Australasian region. Neil Hewitt, Director for Australia, brought over 20 years hydrographic experience to the company and increased its survey capability with his multibeam and LiDAR experience.

In 2009 the UK and Australian divisions of Swathe Services continued to expand despite the tough global economic period and by the middle of the year the company had grown to 7 skilled surveyors and 2 administration staff.

In 2010 the existing UK company was split into two specific divisions to cope with continued growth and diversification. Experienced senior managers for operations and sales joined the group to help increase and build on existing success.

Swathe Services (UK) Limited began managing a team of experienced hydrographic personnel as well as a rapidly expanding pool of marine rental equipment. Swathe Sales & Support Limited was formed to manage marketing and sales for newly secured distributors including Applanix, AUV-S, BioSonics, R2SONIC, Renishaw and Valeport.

In 2011 the company grew once more when it established representation in France and expanded its team to over 14 staff operating around the world. In 2013, Swathe Offshore was launched, a division of the company dedicated to providing personnel support to the marine industry. 

In 2014 Swathe secured UK and European distributor status for Advanced Undersea Vehicles & Systems (AUV-S) making Swathe one of the first marine agents to represent a manufacturer of Unmanned Surface Vessels (USV’s).  In late October of that year Swathe UK and AUV-S jointly launched the new Multi-purpose USV at Hydro14 in Aberdeen. Swathe Australia’s huge success over the years had consistently taken them down a route that was more in line of direct contracting and by the end of 2014 this division became independent and began trading as Precision Hydrographic Services (PHS). Swathe (UK) continues to support PHS but these two companies are now completely separate entities.

In early 2015 AUV-S unfortunately stopped trading and Swathe personnel started working closely developing a strong relationship with ASV Global who, at the time of writing, are dominating the unmanned survey vessel market.  Swathe and ASV teamed up to collect multi-beam data for the Shallow Survey conference that was held in Plymouth in early September.  As pioneers we were the only entity that offered MBES data that covered all the areas from an unmanned platform.  Towards the end of 2015 Swathe ran yet another highly successful HYPACK multi-beam training course out of their Truro based offices.  Dan White joined the team as a graduate surveyor and enthusiastically pulled the Christmas and New Year shift onsite whilst the rest of us enjoyed some well-earned time off over the festive season.

At the start of 2016 Swathe was awarded distributor status for SBG Systems, Renishaw – Merlin mobile laser scanner and CEE Hydrosystems.  Even though the oil and gas market remains depressed business at Swathe is good and we are now expanding our team to incorporate a new Sales Engineer, Operations Coordinator and Marketing and Communications position.

Swathe Services is a group of companies that provides a complete package of services to the global commercial marine market and prides itself on its commitment to quality and customer service.
