Disclosed is a marine vessel to transport natural gas hydrates (NGH), the marine vessel includes a hull formed from solid NGH and a skeletal structure to support the hull. Additionally disclosed is a container to transport NGH including a block of solid NGH and a skeletal structure to support the block. Further disclosed is a method of fabricating a marine vessel for transporting and storing natural gas hydrates (NGH), the method includes preparing a mold, placing a skin layer in the mold, assembling a skeletal structure in the mold, preparing a NGH slurry, and pouring into NGH slurry into the mold.

A method for manufacturing an integrated hull by using 3D structure type fiber clothes and 3D vacuum infusion process includes: sequentially stacking at least one first fiber cloth, at least one core material and at least one second fiber cloth on a mold; deploying structural materials on the second fiber cloth; stacking the third fiber clothes to cover the structure materials and a part of the second fiber cloth, whereby the first fiber cloth, the core material, the second fiber cloth and the third fiber clothes are formed to a lamination; determining a pipe arrangement of vacuum pipes and first and second resin pipes; deploying a vacuum bag on the lamination and covering the first and second resin pipes and the vacuum pipe; executing the 3D vacuum infusion process; curing the resin; and executing a mold release process to complete an integrated hull.

Marine vessels, including combatant (naval) vessels are produced inexpensively without requiring the use of as many skilled personnel as is conventional. The vessel produced has a high strength metal truss structure (both above and below the water line) capable of carrying major hull loads. A number of curved or doubly curved composite (e. g. GRP) panels produced by vacuum assisted resin transfer molding are fastened by bolts, marine adhesives, and/or rivets to the below water line portions of the truss structure where necessary to handle slamming loads and to reduce water resistance and wake. Substantially flat composite pultruded panels are fastened to the truss structure both above the water line, and below the water line where the resistance to slamming loads and reduction of water resistance and wake are not critical. Necessary equipment is installed within the open truss volume before the above-water-line panels are fully installed.

An additive manufacturing method ay includes depositing thermoplastic material with an additive manufacturing apparatus to form a first section of a mold of a marine article. The first section includes an interior surface having a shape corresponding to a first portion of a hull of the marine article and a support portion including a support surface, the support portion being integrally formed with the interior surface. The method also includes depositing thermoplastic material to form a second section of a mold of a marine article, the second section including an interior surface having a shape corresponding to a second portion of a hull of the marine article. The method also includes joining the first section and the first section together to form at least a portion of the mold.

Systems, methods, and non-transitory computer readable media for manufacturing a boat part made of a fiberglass, the fiberglass including a resin and a glass, using a mold and according to a specification that defines a desired quantity of the fiberglass to apply to the mold. In one embodiment, a system includes an applicator configured to apply the fiberglass to the mold, a resin transporter configured to supply the resin to the applicator, and a glass transporter configured to supply the glass to the applicator. A control module is configured to make a comparison in real-time between an actual quantity of the fiberglass applied by the applicator and the desired quantity of the fiberglass to apply to the mold, and to calculate a remaining quantity of the fiberglass to apply to the mold to thereby achieve the desired quantity. The control module is configured to cause an indicator device to indicate in real-time the remaining quantity of the fiberglass to apply to the mold.

Provided is an apparatus for molding a shell hull made of composite material for a boat having a first mold part and a second mold part, each having a molding surface and adapted to be coupled to jointly define a concave molding cavity that extends longitudinally between a stern end and a bow end. The apparatus has a humidity sensor for detecting humidity at the first and/or second mold parts. A plurality of sensors, arranged in a respective plurality of detection positions on a detection surface extending over at least one of the first mold part and the second mold part, and arranged directly in contact therewith, produce signals representative of respective strains of the detection surface in directions substantially perpendicular to the detection surface.
