Abstract: Method of installing a foundation (1) having a toe (2) which is inserted into a soil (10) until a depth of the toe (2) reaches at least a minimum installation depth threshold (23). During insertion, fluid is jetted from a plurality of nozzles (7) provided at the toe (2) for directing fluid distally into the soil (10) ahead of the toe (2). The jetting of fluid from the plurality of nozzles (7) is controlled based on the depth of the toe (2), wherein the rate of jetting of fluid is reduced when the depth of the toe (2) reaches a stabilisation depth (22) ahead of the minimum installation depth threshold (23).

Abstract: A pile holding system configured to be mounted on a vessel, which comprises a support assembly configured to be mounted on the vessel, and a pile holder. The pile holder has a center axis, and is mounted on the support assembly. It is configured to in a vertical orientation hold the pile along a center axis of the pile holder, and guide the pile while it moves there along. The pile holder comprises one or more rings, and a pile holder frame supporting the lower ring and upper ring mutually spaced along the center axis. Each of the one or more rings comprises a ring structure and multiple pile engaging devices connected to the ring structure such as to be distributed about the circumference, each device being adapted to engage an exterior of a respective region of the pile extending inside the respective ring for holding and guiding the pile. The pile holder comprises one or more sensors or markers which are spaced from each other along the center axis and arranged such that a comparison between indications by the sensors or between observed positions of the markers indicates a vertical inclination of the longitudinal axis of the pile held along the center axis of the pile holder.

Abstract: A method of assembling a jacket structure (100) that includes two or more legs (14, 24) and plural crossing braces extending between the legs (14, 24) and forming cross joints is provided. A first component (10) of the jacket structure (100) is provided which includes a first of said two or more legs and a first set (11) of brace structures (50). Each brace structure (50) includes a section of a first brace (51) and a section of a second brace (52), the sections of the first and second braces (51, 52) being at one end attached to the first leg (14) at respective first and second leg-brace joints (15) that are spaced apart. The brace structure (50) and the first leg (14) form an A-frame. A second component (20) of the jacket structure (100) that includes a second set (21) of brace structures (50) and a second part (60, 70) of the brace cross node is further provided. The first component (10) of the jacket structure is mounted to the second component (20) of the jacket structure by joining the first and second parts (60, 70) of the brace cross nodes to form full brace cross nodes (80).

Abstract: For controlling movement of a cantilever of an offshore platform, displacements required for displacing an item to a target position including longitudinal skidding displacement and transverse skidding displacement of the cantilever of the cantilever are determined from current position data and target position data. From position dependent support load data support loads during the longitudinal skidding displacement are determined. If and until a sum of support loads or a highest support load decreases during the longitudinal skidding displacement towards the target position, the longitudinal skidding displacement precedes the transverse skidding displacement. If a sum of support loads or a highest support load increases during the longitudinal skidding displacement towards the target position, the transverse skidding displacement towards the target position precedes the longitudinal skidding displacement.
