Abstract: A welded structure is formed by arranging multiple pieces on a three-dimensional support base to provide an assembly in accordance with the structure to be welded and making a picture map of the assembly by photographing the assembly. Weld points are identified from the picture map and welding parameters are determined from the picture map. Control data specifying the weld points and welding parameters are supplied to welding equipment that is operable in a three-dimensional X-Y-Z coordinate system. The welding equipment is moved in the X-Y plane on the basis of the picture map and said control data. The welding equipment is moved along the Z-axis on the basis of Z-axis position data that are acquired by repeatedly measuring the Z-axis position of the support base.

Abstract: Constituent pieces of a structure to be welded are arranged in a desired configuration on a support surface and are welded together at a plurality of weld points to form the welded structure. At least one image of the arrangement of the constituent pieces on the support surface is recorded and the positions of the weld points are determined from the image(s). The welding of the constituent pieces is controlled on the basis of the determined positions of the weld points.

Abstract: A fire resistant and sound insulating wall structure, particularly for the ship building industry, includes vertical stiffeners and a surface plate attached to the vertical stiffeners, preferably by gluing. A relatively thin corrugated plate is attached to the surface plate by gluing. The corrugations of the corrugated plate are substantially horizontally oriented and accordingly the corrugated plate provides horizontal stiffness. The glue attachment of the surface plate to the vertical stiffeners is preferably secured by means of screws for maintaining the fire-resisting properties of the structure in the event of the glue being destroyed by the heat of a fire.

Abstract: A service vessel that is designed for navigating both in the open sea and in ice conditions is provided with a demountable propeller nozzle. For an ice-free navigation period the propeller nozzle is mounted around the propulsion propeller of the vessel, whereas for a navigation period in ice conditions the propeller nozzle is removed. The power absorption of the propulsion propeller is maintained constant during nozzle and nozzle-free operation.

Abstract: A sound source arrangement for use in carrying out a seismic survey comprises flexible structural modules connected together end-to-end to form an elongated flexible structure of substantially uniform exterior cross-sectional shape and size. The elongated flexible structure can be stored on a reeling unit and may be unwound from the reeling unit at a survey location and wound back onto the reeling unit without disconnecting the modules from one another. At least one of the flexible modules is an air gun module which includes a device for producing sound impulses.

Abstract: A relatively wide vessel is assisted through an ice field by an icebreaker having a relatively narrow hull. The icebreaker includes two steerable propulsion mechanisms at the opposite ends respectively of the hull, and the propulsion mechanisms are used to propel the icebreaker through the ice field in a direction at a substantial angle to its keel line, thereby opening in one pass of the icebreaker a passage having a width substantially greater than the waterline width of the icebreaker.

Abstract: In a press bending arrangement for an aluminum profile, especially for manufacturing the equator profile for an LNG-tank, the press is connected to control and measuring devices in such a manner, that the reflection of the workpiece is taken into account both in bending the profile and in determining the bending control based on measurements being made.

Abstract: A large ship comprises a hull and several cargo tanks. Each cargo tank has substantially semi-spherical bottom and top portions; the bottom portions of the tanks and the top portions of tanks all being of substantially equal radius of curvature. At least one tank has a substantially cylindrical intermediate portion that interconnects the bottom and top portions of the tank and is of substantially equal radius of curvature to the bottom and top portions of the tanks.

Abstract: A berth arrangement for installation in a sleeping compartment having a ceiling formed with a downwards open recess, comprises a berth holder and a bearing for mounting the berth holder for turning relative to the ceiling structure between a generally horizontal retracted position and a generally vertical lowered position. A berth is journalled in the holder to be turnable when the holder is in its lowered position between an extended position, in which the berth extends substantially horizontally away from the holder, and a folded up position, in which the berth is disposed substantially vertically and is close to the holder.

Abstract: A water equilibrating arrangement for a marine vessel comprises a trough that is in fluid flow communication with first and second closed or closeable compartments that are separated by an essentially imperforate structure and a baffle that extends downward from the imperforate structure into the trough and defines a passage that provides fluid flow communication between the compartments. In the event that water enters one of the compartments due to damage to the vessel, water can flow rapidly into the other compartment for equilibrating water load in the two compartments. Flow of gas through the trough is prevented when a substantial portion of the trough is filled with a liquid or a flowable solid or semi-solid material.

Abstract: A large spherical vessel is produced by welding commercially available large plane metal plates together to form a composite plane plate, cutting the composite plane plate to a form adaptable to a spherical surface, and thereafter forming the resulting composite plate blank to spherical form.

Abstract: Underwater sound from a marine vessel driven by one or more propellers is damped by introducing air and/or other gas into the vessel's propeller flow(s) so that the turbulence of the propeller flow(s) causes mixing of the air/gas and water and disintegration of gas bubbles. The majority of the gas bubbles formed in the water are from 1 to 20 mm in diameter.

Abstract: A plate body is formed from two plane metal plates each at least 5 mm thick and having an edge at least 10 meters long, by machining each plate along its edge to form a welding groove with high accuracy relative to the dimensions and shape of the groove and with a smooth groove surface. The groove extends from a first side of each plate through only part of the thickness of the plates to leave a root area at the second side of the plate. The plates are supported in the vicinity of the welding groove from the second side of the plates by a support bed and are retained by use of suction in relative positions such that the root areas of the two plates are in confronting and contacting relationship. A weld is created in the welding groove by butt joint welding from the first side only of the plates.
