Development and Field Trials of a Drop-Down Video System (2003)
Envision Mapping was contracted by the Countryside Council for Wales (CCW) to develop a purpose built drop-down video system suitable for marine monitoring work. Detailed specifications were prepared and the system was manufactured by C-Technics, a specialist underwater video systems manufacturer. The system was trialled during the manufacturing process and modifications made prior to the system being completed. Upon completion the system was commissioned at three locations in Wales. This tested the system in field conditions for both operational suitability and also enabled the system to be modified to best suit the requirements of CCW.

The system was deployed in various sea states over a 5 day period, in Tremadog Bay, close to St Tudwal’s Islands, the Menai Strait and Milford Haven. The system was deployed from the RIB Aplysia and the RV Skalmey. The methods used were similar to the procedural and operational guidelines presented below, but various configuration of camera position, buoyancy and towing techniques were tried. The equipment and deployment techniques were refined and adjusted to produce the optimal configuration and operational techniques for various conditions and these methods are presented in the procedural and operational guidelines. Recommendations are made for methods of data collection, the effects of weather conditions, sea state and tides on the deployment of the system. Because the system is to be used on various vessels, examples of mobilisation configurations are presented.
