    摘要： A diverless system for levelling a template adjacent the floor of a body of water comprising a plurality of fluid-pressure activated gripping assemblies pivotally coupled to the template and receiving the supporting piles therein, with portions of the piles extending above the template; and a jacking assembly capable of being lowered down each of the piles, releasably connected to the template adjacent the associated gripping assembly and raising or lowering the template in the area each of each pile to level the template. The jacking assembly comprises an outer housing, and a double acting hydraulic piston slidably received in the housing, with a pile gripping assembly being coupled to the piston. The gripping assembly in the jacking assembly and those in the template are each formed from a plurality of ring segments that are serrated on the inside and have tapered ribs on the outside, these segments being received in a bowl having corresponding tapered ribs. The segments are spring biased upwardly and inwardly into the pile gripping position and released downwardly and outwardly by hydraulically actuated pistons. Without diver intervention, fluid under pressure is delivered to the gripping assemblies coupled to the template.The method of installing the template comprises landing the template on the floor of the body of water, passing a set of casing piles through passageways in the template and implanting the casing piles in the floor of the body of water with portions of the piles extending above the template, levelling the template, and rigidly connecting the levelled template to the piles. The step of levelling the template includes actuating the gripping assemblies coupled to the template. This step is preceded by the step of remotely delivering fluid under pressure from a fluid reservoir at the surface of the sea to each gripping assembly without underwater manual, i.e., diver, intervention.

    摘要： A jack usable for leveling a marine platform jacket by lifting a tubular leg or pile guide relative to a pile extending upwardly therethrough includes a gripping unit having slips which engage and grip the pile and which in a predetermined elevated condition of the tubular member are engaged by that member and urged axially thereby in a grip tightening direction acting to positively lock the gripping unit against movement either upwardly or downwardly relative to the pile.

    摘要： In a clamp system for a slender object (16), such as a pile or pipe and the like, a clamp (1) and the object are to be applied around one another. The clamp has a frame (4) defining an axial direction. Furthermore, gripping devices (3) are provided which are spaced in circumferential direction of the frame (4). A stop (25) defines an end position of the gripping device (3), the gripping device (3) in gripping state and positioned in the end position prevents the object (16) from displacing with respect to the frame (4) in a first axial direction of the passage (9), in which first axial direction the gripping device (3) is held pressed against the stop (25), and the gripping device (3) allowing the object (16) to displace with respect to the frame in the second axial direction opposite the first axial direction.

    摘要： 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.
