Leg load distribution and locking arrangement for jack-up type mobile offshore platform
Patent
·
OSTI ID:6810565
A plurality of vertically extending guide means is carried by the structure of a jack-up type mobile offshore platform. The guide means is spaced about each of the vertically extending legs which engage the floor of a water-covered area and enable the hull, forming part of the structure, to be elevated and supported in position above the water in the water-covered area. A first pair of wedges forms a first wedge means that is movable vertically in each of the guide means, and a second pair of wedges forms a second wedge means that is spaced vertically in each of the guide means relative to the first wedge means. The first and second wedge means are also movable vertically in the guide means. Means interconnect the pair of wedges which form each the first and second wedge means so that one of the wedges of each pair may be moved to engage a vertical leg chord and thereby lock the legs to the structure and distribute loads and more particularly horizontal loads applied to the structure at joints of the vertically extending leg chords, that is, at the intersection of the vertical leg chords with the respective laterally extending braces between the leg chords.
