Abstract
Abstract The invention relates to a marine platform for supporting a deck or a similar working structure above the water''s surface at an offshore location. The platform includes an uprightly positioned support jacket that extends to the sea floor, having anchoring means at the lower end for fixedly positioning the jacket in place. The anchoring means is so arranged with respect to the jacket to firmly locate the latter even though the anchoring substratum be underconsolidated, or characterized by generally poor holding ability. Said anchoring means embodies a series of peripherally located skirt piles that are sloped inwardly at an angle toward the support jacket interior to increase the resistance of the jacket to being displaced or upset from a vertical disposition. Lateral storm loads imposed against the jacket are thus transferred to the foundation strata by axial pile loads only. Safety, stability against overturning and total collapse of the entire marine structure is thereby improved.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
172 words
A marine platform adapted for being submerged and fixed to the floor of an offshore body of water and including; an uprightly disposed support jacket having a plurality of elongated legs extending the length of said jacket, said legs being disposed in a generally outward direction from the jacket, a base fixed to the jacket lower end and being mutually connected to the respective elongated legs, and anchoring means fixed to and depending from said jacket lower end whereby to anchor said platform to the floor of said offshore location, said anchoring means including; a. a first anchoring system comprising at least one main anchor pile connected to and depending from the end of each plurality of elongated legs, a portion of said main anchor piles being embedded into the substratum of said floor, b. a second anchoring system including a plurality of skirt piles depending downwardly from said jacket base and being embedded into said floor, said respective skirt piles being canted from a vertical disposition, inwardly toward the jacket interior.
Claim 2
Dependent Claim
172 words
A marine platform adapted for being submerged and fixed to the floor of an offshore body of water and including; an uprightly disposed support jacket having a plurality of elongated legs extending the length of said jacket, said legs being disposed in a generally outward direction from the jacket, a base fixed to the jacket lower end and being mutually connected to the respective elongated legs, and anchoring means fixed to and depending from said jacket lower end whereby to anchor said platform to the floor of said offshore location, said anchoring means including; a. a first anchoring system comprising at least one main anchor pile connected to and depending from the end of each plurality of elongated legs, a portion of said main anchor piles being embedded into the substratum of said floor, b. a second anchoring system including a plurality of skirt piles depending downwardly from said jacket base and being embedded into said floor, said respective skirt piles being canted from a vertical disposition, inwardly toward the jacket interior.
Claim 3
Dependent Claim
32 words
In a marine platform as defined in claim 1 wherein; said base includes a continuous member extending peripherally about the jacket lower end in engagement with said respective plurality of elongated legs.
Claim 4
Dependent Claim
47 words
In a marine platform as defined in claim 1 wherein; said base includes a plurality of cylindrical base members being terminally connected one to the other to define a continuous base extending peripherally about said jacket lower end in engagement with said respective plurality of elongated legs.
Claim 5
Dependent Claim
38 words
In a marine platform as defined in claim 1 wherein; said jacket includes at least three elongated legs extending longitudinally of said jacket, and each of said legs being spaced from at least two adjacently positioned skirt piles.
Claim 6
Dependent Claim
34 words
In a marine platform as defined in claim 4 wherein; said at least two adjacently disposed skirt piles include at least one of said piles being spaced at opposed sides of an elongated leg.
Claim 7
Dependent Claim
70 words
In a marine platform as defined in claim 1 wherein; said second anchoring system includes a plurality of skirt pile guides depending from said jacket base, each having the longitudinal axis thereof canted from a vertical disposition inwardly toward the jacket interior, and at least one skirt pile being fastened internally of each of said skirt pile guides, the lower end of said skirt pile being embedded in the substratum.
