摘要:
Wind farm comprising at least one buoyant structure carrying two or more wind turbines. The wind turbines can have a fixed orientation relative to the buoyant structure and the planes of rotation of the wind turbines can be within the same plane, allowing a shorter minimum distance between the turbines. The wind turbines do not need a yaw mechanism. The buoyant structure can be provided with a turret mooring system to permit the buoyant structure to weathervane to the desired upwind or downwind position. Optionally, the structure may be provided with one or more thrusters on for a more exact positioning of the buoyant structure.

A variable-draft vessel (10), as is shown in Figure 1. The variable-draft vessel includes a center hull (25), a first side hull (15) that is coupled to a first side of the center hull, a second side hull (20) that is coupled to a second side of the center hull, and at least one cross support (30) coupling the first and second side hulls, wherein the center hull is configured to be vertically translated with respect to the first and second side hulls.

A liquefied natural gas carrier uses a diesel engine or gas turbine propulsion plant fitted with a shipboard regasification system. The propulsion plant can provide either a direct mechanical drive of the propeller shaft and propeller, or can be fitted with an integrated electric power plant using an electric motor or motors to drive the propeller shaft and propeller. The regasification system includes a heat input source of exhaust gas heat exchangers, electric water heaters and supplemental heaters to provide an additional heat source to a hot water circulating loop. The liquefied natural gas contacts the hot water or heating medium circulating loop and is regasified. An undersea conduit from the ship transmits the regasified natural gas to an on shore plant.
摘要:
A display device (8) such as a flat screen television may be stowed away out of sight within a cabin by partly recessing into a moulded coaming (3) forming part of the boat's superstructure (1) in addition to being partially received in a special housing (7). In this way, the fact that a display device (8) is hidden out of view is made less obvious because the housing (7) does not conform to the shape of the display device (8).

A retrofitable breech (102) utilizing gas generators (106) such as commercial off the shelf automotive airbag inflators, for propelling a torpedo (18) from a tube (20).

A monohull marine platform (20) is provided which includes a plurality of bows (29,30,31) each having a flat lower keel (47) . A transverse stern seal (122) is connected to the bows using an inclined lift surface (128) and a pair of outboard seals (119,120)forming an air chamber. Pressurized ail is forced into the air chamber to form a pressurized air cushion (129) under the platfomr. Respective water flow channels (56,59) disposed between each pair of the plurality of bows diminish wave energy during operation. As the platform passes through the water, the platform utilizes a combination of flotation, pneumatic, and hydrodynamic for reduced resistance and drag.
摘要:
A method of reinforcing a metal panel or pipe of an existing structure comprising the steps of attaching a reinforcing metal layer to said metal panel or pipe in spaced apart relation to thereby form at least one cavity between inner surfaces of said metal panel and said reinforcing metal layer, injecting an intermediate layer comprised of an uncured plastics material into said at least one cavity, and curing said plastics material so that it adheres to said inner surfaces of said metal panel or pipe and said reinforcing metal layer.
