TELESCOPING SPAR PLATFORM AND METHOD OF USING SAME

WIPO Patent Application WO2002098725

A3

A telescoping spar structure (10) designed to be scalable for use with very large floating platforms to relatively small floating platforms includes a platform/hull (26) for supporting a payload (24); a telescoping spar (12) attached to the platform/hull that includes several interlocking tubes (14) extending from a shallow end to a deep end of the spar, the tubes configured to telescope in and out of adjacent tubes such that the tubes are nestable together in a stowed configuration; a buoyancy chamber (18) attached to the spar between shallow and deep ends of the spar; and, a damping chamber (20) attached to the spar between the buoyancy chamber and the deep end of the spar, the damping chamber including: a first compartment for entraining a volume of water, a second compartment for enclosing deployment ballast (22), and a release mechanism (36) for jettisoning the deployment ballast from the second compartment after the spar structure is deployed, enabling the platform to rise to an operational height relative to the waterline (34).
