A watercraft system is provided. The watercraft system includes a hull and a plurality of removable pods. Each pod has a different operational characteristic to alter the configuration of the watercraft depending on which pod is inserted. The hull has a pod opening for receiving a selected one of the removable pods. A method and apparatus for transitioning various ones of the pods between different positions is also provided.

Embodiments described generally relate to methods for assembling a modular floating production storage and offloading (FPSO) vessel. A cargo module section, a forward module, and a rear module can be positioned and aligned with each other such that the cargo module section can be disposed between the forward module and the rear module. A plurality of connectors can be coupled together to secure the forward module and the cargo module section together and another plurality of connectors can be coupled together to secure the rear module and the cargo module section together. A first topside module can be installed onto or over an upper surface of the forward module and can include a flare tower, a turret, hydrocarbon production equipment, or any combination thereof.

The present invention relates to a semi-submersible platform (1) for maritime applications such as wind power, electrical substations or hydrogen generation plants, wherein the semi-submersible platform (1) comprises a base body (2) made of concrete equipped with internal compartments (3) adapted to house ballast water, and three or more buoyancy columns (4) substantially made of concrete, wherein said columns (4) protrude from an upper face of the base body (2) and are arranged at the vertexes of the base body (2), wherein at least one column (4) is internally equipped with respective concentric rings (5, 6), an inner ring (5) and an outer ring (6), joined together by a plurality of radial walls (7) that define anti-flood compartments (8).

In an assembly of an offshore support structure for a wind turbine, tubular members are interconnected in grouted connections where a first tubular member has fastened to it a shell-unit comprising a cavity into which an end-part of a second tubular member is inserted and fixed by grouting. The cavity is closed by a rigid entrance-flange that is fastened to the walls of the shell-unit. The design converts forces acting on the second tubular member to compression forces acting on the grout in the cavity.

A boat hull (1) for a boat, with a boat drive (2) which extends through a hull opening (3) in the bottom of the boat hull (1). The boat drive (2) is connected to the boat hull (1) by at least one fastening member (4). To do this, at least one positioning element (5) is provided, on the outside (6) of the boat hull (1), for positioning the fastening member (4) relative to the boat hull (1).

A chain brace for restricting relative movement between first, second, and third serially connected links of a chain. The chain brace can include a wedge block defining a bore at least partially therethrough, first and second outer blocks, a capture frame that can include a reaction plate that can define a bore therethrough, and a tension member. The capture frame can be configured to position the outer blocks and the wedge block within the second link of the chain. The tension member can be positioned through the bore defined by the reaction plate and into the bore defined by the wedge block to apply a force on the wedge block such that the wedge block displaces the first and second outer blocks into contact with the ends of the first and third links of chain, respectively, to restrict relative movement between the first, second, and third links of the chain.

An approach for assembling a maritime vehicle includes forming a keel panel from a single sheet of metal, forming a first side panel from a single sheet of metal, forming a second side panel from a single sheet of metal, and forming a lip member. The first side panel and the second side panel are temporarily coupled with the lip member. The keel panel is secured with the first side panel and the second side panel using a cold joining process.

The present invention relates to a novel apparatus and method for installing split line cutters on marine propeller shafts. The apparatus features a clamshell design comprising an upper and lower half, each with an inner cavity configured to accommodate a portion of the split line cutter. A hinge mechanism connects these halves, facilitating easy opening and closing around the propeller shaft. Key to this invention is a captive screw retaining mechanism within the clamshell, designed to hold screws in place even when unfastened, thereby simplifying the installation process and preventing loss of components. The apparatus includes a screwdriver opening aligned with a bolt cavity, allowing for engagement of captive screws. Additionally, the invention features temporary closure mechanisms, for secure handling during installation, and a retaining hole for attaching a line. This invention offers significant improvements in the installation of line cutters, emphasizing safety, efficiency, and ease of use.
