The invention discloses a manufacture technology for a hatch coaming and a hatch cover. The manufacture technology mainly comprises steps of the positioning of the hatch coaming, the surplus cutting, welding, then the assembly of the hydraulic equipment, pipelines and the electrical equipment, and then the hoisting of the hatch cover, the installation and the final debugging; the hatch coaming and the hatch cover adopt the following steps that firstly the actual main deck line type of the position of a dock where the hatch cover is positioned is copied onto a platform, and then positioning, the accurate detecting and welding are carried out according to the shape and the height of the hatch coaming on the platform; then the hydraulic equipment, the pipelines and the electrical equipment are assembled, after that, the hatch cover is hoisted; and finally the whole manufactured hatch coaming and the hatch cover are hoisted in a hatch position for one time and to be fixedly connected with a boat. Through the technology, the hoisting frequency of a gantry crane is reduced during the hoisting process, the hoisting time is reduced, and the hoisting efficiency is improved; the construction on the platform enlarges the usable operating region, and simultaneously the construction is more convenient and securer.

A boat having a deck and a hull includes a suspension for suspending the deck with respect to the hull. Sensors are employed to determine motion of the deck, with a controller adjusting the suspension such that it maintains the pose of the deck with respect to an inertial reference and with respect to pitch, roll, and heave of the deck.

A marine vessel includes an outboard motor mounting portion provided at a stern of a hull, an outboard motor locating hole provided rearward of the outboard motor mounting portion and near the outboard motor mounting portion and penetrating vertically through the stern, a platform provided rearward of the outboard motor locating hole, and an outboard motor located in the outboard motor locating hole and mounted to the outboard motor mounting portion. This structure enables an occupant of the marine vessel to freely move in a space around the outboard motor on the platform and use the space.

A deck ascent and descent type worktable ship comprises a platform body, and a plurality of columns which causes the platform body to ascend and descend randomly by means of an oil jack jacking system. The deck of the platform body is provided with an erecting device which causes a single pile or tower integrated windmill to form a support movably on the deck of the platform body. Furthermore the single pile or tower integrated windmill can be randomly lifted from a falling-over state or an inclination falling-over state. The erecting device comprises a base frame and a supporting guide frame. The base frame can randomly move on a guide rail which is laid on the deck of the platform body. The supporting guide frame is supported by the base frame through a bracket according to a mode of lifting randomly. Furthermore the single pile or tower integrated windmill can be detached randomly. At severe sea and weather conditions of outer sea, the on-sea wind power generating devices such as the single pile or tower integrated windmill can be loaded, conveyed and lifted, thereby providing the deck ascent and descent type worktable ship which has the following advantages: high operation efficiency, high stability and high safety.

Flooring underlayments may be formed by combining an epoxy based resin component, a curing agent component, and an aggregate component. The resulting underlayment may be a lightweight material with a low viscosity that allows the underlayment to be self-leveling. Further, the underlayment may be designed for application in both wet and dry spaces. In certain embodiments, the underlayment may have a weight less than approximately 7.8 kg/m² (1.6 lb/ft²) when applied at a nominal thickness of 0.635 cm (0.25) inches. Moreover, the underlayment may be designed to conform to the SOLAS requirements administered by the International Maritime Organization (IMO). Specifically, the underlayment may be designed to conform to IMO Resolution MSC.61(67).

In a first aspect, a multi-hull platform boat comprises an upper deck or platform that is secured to a plurality of longitudinally extending hulls via a plurality of corresponding longitudinally extending connectors. Each connector extends from the bottom of the platform above a corresponding hull. The platform is constructed with a continuous uninterrupted planar lower support spanning the area between the connectors. The lower support is preferably made from one or more moldable materials and may be covered with a finish coating. In a second aspect, a multi-hull platform boat has a platform with a relatively planar upper support surface and a wedge-shaped base extending from the upper support surface of the platform to the bottom of the hulls. The base is wedge-shaped such that it increases in height from the front to the rear of the boat.

A method for reconfiguring the hull form of a reconfigurable variable-draft vessel having a side hull and a center hull. In a method in accordance with the illustrative embodiment of the present invention, ballasting and de-ballasting operations assist in the vertical translation of the center hull relative to the side hull.

The present application relates to a method for treating wood and wood-based materials for enhancing dimensional stability and surface properties and also for preventing cracking and extending durability. More specifically the invention for the treatment of wood and wood-based materials is directed to a method wherein the wood or wood-based material is subjected to a thermal treatment and the wood or wood-based material is at least partly impregnated with a melamine-containing resin. Subsequently the wood or wood-based material thus impregnated is cured with hot steam at not more than 125° C. preferably up to a maximum of 120° C. In a further aspect the present application includes the thermally treated wood or wood-based material, impregnated with melamine resin and cured, that is obtainable from the method of the invention. The present invention lastly provides for the use of melamine-containing resin for impregnating wood and wood-based materials which are or have been thermally modified, for the purpose of increasing the hardness and reducing the dimensional change through thermal modification. The material produced in accordance with the invention can be used as a substitute for teak.

An installation vessel has upper and lower decks (40, 50) that are vertically spaced about 3 meters apart, with most of the lower deck covered by the upper one, but with a rear portion (60) of the lower deck being uncovered. The upper deck is used primarily for storage, while the lower deck is the one used for installation of anchor chains, wires, ropes, etc. that pass from a winch (81) to a stern roller (84) at the rear of the lower deck, so dangerous conditions of chains, wires, ropes, etc. moving along a deck during installation are confined to the lower deck. A main crane (72) that lies on one side of the vessel, lies forward of the rear end of the upper deck at a location wherein the crane can reach all portions of the uncovered lower deck portion and most of the upper deck.

The invention discloses a method in the technical field of shipping hoisting, in particular to a modification method of a large-scale crane ship based on a large-scale oil tanker with longer parallel middle body. The floating force is increased through assembling a modified ship bow and box-shaped floating bodies at the two sides of a ship body, and the modification of the large-scale crane ship is realized through replacing a main deck by a beamless flat deck, arranging a crane and reinforcing the interior of the ship body. The invention meets the requirement on controlling the floating state during the working of the large-scale crane ship, improves the total longitudinal strength of the shipping through the arrangement of a modified deck and a centerline bulkhead, and meets the requirement on local intensity through the design of a barrel-shaped honeycomb structure. Rapid dispensation of ballast water during working is realized through the optimized design of a ballast tank and the arrangement of a ballast water pump; the work performance and the control performance are improved through configuring an auxiliary machine, an anchoring machine, a winch and a bow thruster so as to realize that the large-scale oil tanker is modified into the large-scale crane ship on the basis of little modification, therefore, the time and the cost are saved; and the method has larger economic effect and finds a new way for developing old ships.
