A Novel Platform for Data GatheringHugh Young1 and Stephen Phillips21Makaira, Mead End Road, Sway, The paper describes the application of automated semi-submersible technollogy to the gathering of data from the ocean. The technology is known as SASS (Survey Autonomous Semi-Submersible) technology. SASS technology aims to provide a ship substitute at low cost, and applies to gathering data using standard ship-born instrumentation below or above the air/sea interface. It is used to deploy sensors to horizon range from ships or shore to:
The design criteria are easy handling and low noise, together with low capital and running costs. The technology involves an unmanned submerged torpedo-like body running below the waves with a strong upright strut penetrating the water surface. The strut provides buoyancy, air for propulsion and radio frequency coverage for communications and DGPS positioning. A large detachable instrument compartment in the front of the hull allows flexibility to fit underwater sensors, including a winch for lowering instrumentation while the semi-submersible technology allows the vehicle to remain at a fixed GPS position. In addition above water sensors can be fitted on the strut. The paper describes development to date. Funding has been obtained to build a full-scale 4 metre model capable of conducting real surveys. The design progres so far will be described, leading to trials in late 2003. Submitted on January 22, 2003 |
