Cable and Fairing

Vehicle undulation performance is cable dependent, and for real-time control and data acquisition, the Rochester 7-H-314A-XX cable provides the strength, weight and diameter ratios which yield the impressive performance from our range of vehicles. All cables are supplied with standard connectors providing simple cable management and maintenance.  Undulating performance is extended, when required, by use of fairing mounted to the cable. Use of fairing reduces strumming, but more significantly reduces the drag on the cable through the water, and enables the greater depths that can be achieved. Many of our customers have chosen this option as it is both robust and cost effective. Further information on cables and fairing can be found in the following datasheets:

Deck Equipment - Winches

Chelsea can offer a wide choice of winches, specifically designed for its range of undulating vehicles. Winch models vary from light weight systems, designed for the smaller vehicle which can be easily fitted and removed from small craft such as dive, fishing or coastal research boats. On the other end of the scale, we can also offer high performance dedicated winch systems, designed to accommodate faired cable, with integral load cells and cable feed metres, which are generally fitted to larger research and surveying ships. These winches can be offered as either hydraulically or electrically powered, or when required separate hydraulic power units can be provided. Simple sheaves designed for both faired and non-faired cable can also be offered.  Further information on winches can be found in the following datasheets:
