Example embodiments relate to apparatuses, systems, and methods for securing an offshore platform to a bottom of a body of water comprising a shear assembly and a sleeve assembly. The shear assembly is operable to secure to the offshore platform at a first end and having a first connector portion at a second end. The sleeve assembly comprises a sleeve body forming an interior opening, the interior opening operable to receive at least a pile. The sleeve assembly further comprises a second connector portion secured to the sleeve body, the second connector portion securable to and un-securable from the first connector portion of the shear assembly.
摘要:
A structure for mounting offshore installations such as wind turbines or oil and gas platforms. The structure comprises a base, a top piece, and a lattice structure connecting the base to the top piece. The sub-components of the structure can be pre-assembled prior to installation to facilitate ease of construction, or they may be transported to a pre-determined location and assembled on site.
摘要:
A node structure (12, 14) for connecting two or more convergent members (16, 26) of a lattice frame to each other and to one or more other members of the lattice frame. The node structure (12, 14) comprises a pair of opposed spaced-apart faces (30) that are substantially planar and substantially parallel to each other. At least one pair of root formations (32) with respective central longitudinal axes define an interior angle between them, those axes diverging outwardly for alignment with respective members of the lattice frame and converging inwardly between the faces (30). An inner connecting wall (34) between the root formations (32) of the pair connects concave-curved inner edges (36) of the faces and extends in a concave curve around the interior angle to join the root formations (32) of that pair.

Working platform (6) and offshore wind energy plant (2) comprising a working platform (6), wherein the working platform (6) is configured to be mounted to an outside wall (16) of the tower (4) of the offshore wind energy plant (2) by help of welded joints.
摘要:
A cable hang-off arrangement for an elevated support including a cable assembly with a flexible reinforced protective tube for accommodating a transmission cable arrangement, a mounting assembly arranged on the elevated support, and a lifting assembly for lifting the cable assembly from a lower level to the elevated support, which lifting assembly is realized to engage with the mounting assembly such that the cable assembly is suspended between the elevated support and the lower level. An offshore facility mounted on an elevated support above a variable lower level including a transmission cable arrangement and a flexible protective tube for guiding the transmission cable arrangement through an essentially vertical direction from the elevated support to the lower level into an essentially horizontal direction at the lower level is also provided. A method of mounting such a cable hang-off arrangement is also provided.
摘要:
A structural entity for transferring structural loads from a Tower of a Wind Turbine Generator to its Foundation, by means of a Plated Transition Piece characterized in that it consists of a cylindrical central body connected by a series of inclined plates and shear plates and beams to legs that connects to a foundation structure.
摘要:
The invention concerns a transition body arranged between a lower section and an upper section of a tower for a wind energy plant. The lower tower section is constructed from several corner posts configured as hollow profiles and the upper tower section is configured in the form of a tubular tower which is essentially round in cross section, with a bottom and a connection flange disposed above the bottom for connecting the upper tower section. The bottom and the flange connect the upper tower section and are joined together by at least one metal casing sheet. The connection of the bottom to the at least one metal casing sheet is a welded construction. A number of connection areas is provided on the underside of its bottom, corresponding to the number of corner posts of the lower tower section.
