The Remotely-Operated Platform for Ocean Science (ROPOS) is a 5000m ca
pable Remotely Operated Vehicle (ROV) that was based on a successful i
ndustrial design. Since delivery of the original vehicle in 1986, exte
nsive modifications have been undertaken to transform ROPOS into an ef
fective tool for deep-sea scientific applications, in close collaborat
ion with scientific users. Modifications include development of new ma
nipulator controls and mechanical sampling tools suited to scientific
tasks, and design and construction of a scientific telemetry system to
interface with scientific instruments mounted on the vehicle. The new
est ROPOS vehicle, constructed in early 1997, incorporates all previou
s modifications and provides several new features including separate h
ydraulic functions for scientific applications and greatly improved ve
hicle and scientific telemetry systems. ROPOS is now operated by the C
anadian Scientific Submersible Facility (CSSF) on a not-for-profit, us
er-pay basis, in a unique partnership involving government, industry a
nd universities.
