Semi-submersible wind turbine platforms capable of floating on a body of water and supporting wind turbines, and a method of manufacturing the semi-submersible wind turbine platforms from advanced cementitious composite material are provided. The method includes determining at a first iteration topological outputs of the wind turbine platform including a plurality of modular sections consisting of an advanced cementitious composite (ACC) material, obtaining a second iteration from the topological outputs, the second iteration including a second model platform and a second model tower of the wind turbine platform, and obtaining addition iterations via simulation to attain a final model platform and a final model tower, the final model platform and the final model tower including a layout of the plurality of modular sections and connections for a platform and a tower of the wind turbine platform.

The invention discloses a processing method for realizing convenient watertight compartmentation based on container ship combined support water blocking cover, comprising following steps: 1) completing manufacturing of the frame; 2) fixing the frame; 3) installing the water blocking cover; 4) the lower end of water blocking cover extends downwards to the half ship outer bottom plating and is fixed; 5) the upper end of the water blocking cover extends upwards and is fixed; 6) after the water blocking cover is installed and fixed, liquid level meter is arranged inside the half ship and record current liquid level to detect liquid level change inside the half ship in real time. Two floating ends of the half ship are unclosed openings, which adopt detachable supports as support with water blocking cover laid on the outside thereof, magnet and the rope used for fixing openings of the half ship for watertight compartmentation.

One example watercraft includes a blow-molded plastic hull in the form of a unified, single-piece, structure, and the structure of the blow-molded plastic hull defines first and second cutting paths. The watercraft also includes a sacrificial portion that is integral with the blow-molded plastic hull, and two different configurations of the sacrificial portion are respectively defined by the first and second cutting paths, and each of the two configurations of the sacrificial portion is removable from the blow-molded plastic hull so that a respective seating configuration is defined in the blow-molded plastic hull.

A method of manufacturing a boat hull comprising: forming a foam mold of a predetermined shape and size from one or more pieces of foam; cutting, into the foam, at least one C-channel running in a longitudinal or a lateral direction within the foam; and coating the foam with at least one layer of reinforcing fiber and resin.

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.
