AQUAshuttle III

Stable, highly robust, undulating vehicle, capable of tow speed from 8-25knots. The vehicle will undulate from the surface to 120 metres.

Nn-Shuttle

Nn-Shuttle is a low cost, large payload vehicle which can be towed from research vessels & ships of opportunity at speeds of 5-15 knots, to operational depths of 150m.

SeaSoar II

SeaSoar is the world's leading open ocean towed undulating data acquisition vehicle. It is capable of undulating from the surface to 500 metres at tow speeds of up to 12 knots.

Chelsea has a vehicle to suit your needs and budgets
CTG can offer small portable systems for use from small research vessels or ships of opportunity to large, dedicated systems that are permanently installed on ocean going research ships. CTG has always adhered to a 'system building approach' within its oceanographic bodies, communications and instrumentation range. This enables clients to start with a basic system, which can be augmented, if required, when further funds become available. As part of this 'starter pack' approach we can investigate the possibility of utilizing a client's existing instrumentation or deck equipment in order to minimize cost. We can also offer complete turn-key systems comprising of a complete instrumentation package, vehicle, tow cable, winch and data acquisition package to cover specific user needs.

With over 150 towed vehicle systems in use worldwide CTG's reputation for reliability is truly unequalled
CTG has been at the forefront of the design, manufacture, supply and commissioning of commercial quality, towed undulating instrumentation platform and systems for over 30 years. Such success is perhaps not surprising in view of the benefits these tools offer both scientists and surveyors. The sheer quantity of data that can be reliably collected from these vehicles while a vessel is underway, has led to the sale of more than 150 towed vehicle systems to research, commercial and defence organizations around the world. CTG vehicle have collectively traveled millions of kilometers through the oceans and seas, demonstrating an impressive reliability record and generating a wealth of operational experience, offering a simple robust method of mapping the upper ocean layer as well as mapping coastal characteristics.
