Abstract
Abstract A floating platform comprises a pontoon and more than three vertical supporting columns which are individually vertically movable relative to the pontoon and are also individually horizontally movable relative to the pontoon so that the pontoon may be moved horizontally over small distances without the need for refloating it.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
90 words
A floating platform comprising a pontoon, more than three spaced frames rotatably mounted on the pontoon for rotation of each frame about its own vertical axis relative to the pontoon, a vertical column mounted in each frame for movement of the column parallel to the length of the column relative to the pontoon and the associated said frame, means mounting each column in the frame for horizontal movement of the column relative to the frame, and means for selectively individually moving each column horizontally relative to its associated said frame.
Claim 2
Dependent Claim
90 words
A floating platform comprising a pontoon, more than three spaced frames rotatably mounted on the pontoon for rotation of each frame about its own vertical axis relative to the pontoon, a vertical column mounted in each frame for movement of the column parallel to the length of the column relative to the pontoon and the associated said frame, means mounting each column in the frame for horizontal movement of the column relative to the frame, and means for selectively individually moving each column horizontally relative to its associated said frame.
Claim 3
Independent Claim
175 words
A method of moving over a body of water a floating platform which is comprised by a buoyant pontoon and more than three vertical columns, comprising supporting the pontoon on the columns above the level at which the pontoon is buoyant in the body of water, and raising at least one column relative to the pontoon out of supporting relationship with the pontoon while maintaining the pontoon supported above said level on at least three columns, rotating said at least one column horizontally rElative to the pontoon about an axis parallel but eccentric to the raised column and lowering the horizontally moved at least one column again into supporting relationship to the pontoon, thereafter raising and horizontally rotating about a parallel eccentric axis and again lowering at least one other column until all the columns supporting the pontoon have been horizontally moved relative to the pontoon, and then horizontally moving the pontoon relative to the columns thereby to translate the pontoon horizontally relative to the body of water while maintaining the pontoon above said level.
Claim 4
Independent Claim

A method of moving over a body of water a floating platform which is comprised by a buoyant pontoon and more than three vertical columns, comprising supporting the pontoon on the columns above the level at which the pontoon is buoyant in the body of water, and raising at least one column relative to the pontoon out of supporting relationship with the pontoon while maintaining the pontoon supported above said level on at least three columns, rotating said at least one column horizontally rElative to the pontoon about an axis parallel but eccentric to the raised column and lowering the horizontally moved at least one column again into supporting relationship to the pontoon, thereafter raising and horizontally rotating about a parallel eccentric axis and again lowering at least one other column until all the columns supporting the pontoon have been horizontally moved relative to the pontoon, and then horizontally moving the pontoon relative to the columns thereby to translate the pontoon horizontally relative to the body of water while maintaining the pontoon above said level.
