Abstract
Abstract The invention relates to a marine platform adapted to be fixedly positioned in an offshore environment by anchoring to the ocean floor. The platform includes a work deck normally elevated above the water''s surface, a foundation pedestal at the ocean floor, and one or more intermediary support columns which connect the deck to the pedestal. The columns are releasably held at their lower ends by remotely actuated clamping means. The elevated deck is thus supportably carried by the columns at an adjustable operating height.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
187 words
An elongated marine platform adapted to be mounted in a substantially upright position and fixed to the floor of a body of water, said platform including: a working deck elevated above the water''s surface, a foundation pedestal at the lower end of said platform and including means to anchor said platform to the floor of said body of water, at least one upstanding support column extending from said foundation pedestal to the water''s surface and being operably engaged with said working deck, said foundation pedestal including column-gripping means at the lower end of said at least one upstanding support column to permit controlled longitudinal movement of the latter with respect to said column-gripping means, and means for remotely actuating said column-gripping means, to control said column movement, said column-gripping means including a continuous bandlike clamp member retained on said pedestal and operable between contracted and expanded positions to permit controlled vertical movement of such columns when said bandlike clamp member is in the expanded condition, and motor means connected to at least one of said clamp member for adjusting said member between said contracted and expanded conditions.
Claim 2
Dependent Claim
187 words
An elongated marine platform adapted to be mounted in a substantially upright position and fixed to the floor of a body of water, said platform including: a working deck elevated above the water''s surface, a foundation pedestal at the lower end of said platform and including means to anchor said platform to the floor of said body of water, at least one upstanding support column extending from said foundation pedestal to the water''s surface and being operably engaged with said working deck, said foundation pedestal including column-gripping means at the lower end of said at least one upstanding support column to permit controlled longitudinal movement of the latter with respect to said column-gripping means, and means for remotely actuating said column-gripping means, to control said column movement, said column-gripping means including a continuous bandlike clamp member retained on said pedestal and operable between contracted and expanded positions to permit controlled vertical movement of such columns when said bandlike clamp member is in the expanded condition, and motor means connected to at least one of said clamp member for adjusting said member between said contracted and expanded conditions.
Claim 3
Dependent Claim
44 words
In the apparatus as defined in claim 1 wherein said clamp member includes a semirigid band having opposed ends, and being formed to define an opening having a loop configuration of a sufficient diameter to register a support column in said loop configuration opening.
Claim 4
Dependent Claim
53 words
In the apparatus as defined in claim 2 wherein said semirigid band includes motor means attached to opposed ends thereof, the latter being simultaneously actuable to adjust said clamp member between the expanded and contracted positions whereby to adjust said loop configuration opening into tight engagement with the outer surface of said column.
Claim 5
Dependent Claim
184 words
In an elongated marine platform adapted to be uprightly fixed to the floor of a body of water and including; a deck normally positioned above the surface of said body of water, a pedestal anchored to the floor of said body of water for firmly positioning said platform, and a plurality of support columns extending uprightly between said deck and said pedestal in connecting relation to said pedestal, the latter including a plurality of upstanding cylindrical sockets having axial openings therethrough to slidably receive a support column, at least two brace members laterally connected to the respective cylindrical sockets and opening into the lAtter to define a mutual connecting joint therebetween, clamp means positioned at said mutual connecting joint and including, a gripping band having opposed ends and being formed into a loop of sufficiently large opening to receive a column passed therethrough, motor means connected to at least one end of said band to actuate the latter between gripping and releasing positions by applying an actuating force to said band whereby to control the sliding movement of said column through said cylindrical socket.
Claim 6
Dependent Claim
184 words
In an elongated marine platform adapted to be uprightly fixed to the floor of a body of water and including; a deck normally positioned above the surface of said body of water, a pedestal anchored to the floor of said body of water for firmly positioning said platform, and a plurality of support columns extending uprightly between said deck and said pedestal in connecting relation to said pedestal, the latter including a plurality of upstanding cylindrical sockets having axial openings therethrough to slidably receive a support column, at least two brace members laterally connected to the respective cylindrical sockets and opening into the lAtter to define a mutual connecting joint therebetween, clamp means positioned at said mutual connecting joint and including, a gripping band having opposed ends and being formed into a loop of sufficiently large opening to receive a column passed therethrough, motor means connected to at least one end of said band to actuate the latter between gripping and releasing positions by applying an actuating force to said band whereby to control the sliding movement of said column through said cylindrical socket.
Claim 7
Dependent Claim
31 words
In the apparatus as defined in claim 4 including motor means connected to said opposed ends of said band whereby to simultaneously apply an actuating force to said band opposed ends.
Claim 8
Dependent Claim
21 words
In the apparatus as defined in claim 4 wherein said motor means is fixedly positioned in said laterally disposed brace members.
Claim 9
Dependent Claim
33 words
In the apparatus as defined in claim 4 wherein said clamp means includes a plurality of gripping bands spaced longitudinally along said socket to grip said column at space-apart sections of the latter.
Claim 10
Dependent Claim
27 words
In the apparatus as defined in claim 4 including bearing means carried on said cylindrical socket in engagement with said gripping band to vertically support the latter.
Claim 11
Dependent Claim
53 words
In the apparatus as defined in claim 8 wherein said bearing means includes an annular shoulder piece having an upper rubbing surface, depending from wall of said socket said shoulder extending radially inward to form a passage whereby to receive a support column, and said band slidably and supportably engaging said rubbing surface.
