This invention proposes an ESG-based comprehensive governance assessment method, electronic device, storage medium, and product for shipbuilding enterprises. The method includes: collecting multi-source ESG data and operational data from the shipbuilding enterprise during the assessment period; calculating state baseline parameters based on the operational data according to preset time slices; converting the multi-source ESG data into standard evaluation units and forming ESG vector data corresponding to the preset time slices; matching corresponding ESG assessment parameters from a preset ESG assessment parameter library based on the enterprise size, ship type, or production organization method; if no match is found, adaptively calibrating the ESG assessment parameters to obtain calibrated ESG assessment parameters; calculating governance efficiency indicators for each time slice based on the ESG vector data, state baseline parameters, and ESG assessment parameters; calculating a comprehensive ESG governance efficiency coefficient based on the governance efficiency indicators for each time slice; and obtaining the ESG governance assessment result based on the comprehensive ESG governance efficiency coefficient.

The utility model relates to a deck seamless butt joint auxiliary device for shipbuilding. The deck seamless butt joint auxiliary device aims to solve the problems that traditional deck butt joint is low in precision, poor in efficiency, insufficient in adaptability and the like. The device comprises a deck cross beam, a longitudinal beam, a track plate, a connecting structure, a connecting plate, a suction cup, an extrusion screw rod and a connecting screw rod. A rail plate is arranged above the longitudinal beam, and the inner side of the rail plate is connected with a connecting structure in a sliding mode. The connecting structure comprises a connecting plate, a suction cup is arranged in the connecting plate, an extrusion screw penetrating through the connecting plate is arranged on the suction cup, and a connecting screw penetrating through the connecting plate is arranged on one side of the connecting plate. The track plate is connected with a plurality of connecting plates through the T-shaped sliding grooves and is a pair of symmetrically-distributed frame plate bodies. The connecting plate is provided with a limiting plate corresponding to the sliding groove, and the connecting screw rod and the extruding screw rod are spatially and vertically distributed. A sealing plate is arranged between the extrusion screw rod and the suction cup, and the track plate is an L-shaped aluminum alloy plate body.

The invention relates to boat building. A sail system capable of generating electrical energy comprises a mast, sails, a sliding support, a shaft, beams, a generator, a storage battery, and a motor. A wing-type sail consists of two segments, each segment consisting of a support section and additional sections. The sliding support has devices for setting and adjusting the sail system. The sail system can be reversibly switched from a propulsion mode to an electrical energy generation and storage mode by setting the sails into the wind and then rearranging parts of the sails to generate electrical energy. The sail system enables a vessel to operate independently of external sources of energy.

The present invention relates to an austenitic steel material suitable for use in various fields such as the energy industry and shipbuilding, and a method for manufacturing the same, and more particularly, to an austenitic steel material which can be used in a structure requiring high strength and excellent hydrogen embrittlement resistance, and a method for manufacturing the same, for example, a hull requiring high strength and excellent non-magnetic properties, a steel pipe or facility for transporting crude oil having a high hydrogen sulfide content, and the like.

To provide shipbuilding technology using robotic construction techniques that can reduce costs and time, and minimize errors. [Solution] The system for robotic construction of an ocean-going vessel includes a gantry and a robotic interface connected to the gantry, the gantry being configured to transport the robotic interface in at least two directions. A robot configured to perform construction work is releasably connected to the robotic interface. A robotic controller is positioned on the robot and configured to operate the robot. Controllers are operably connected to the gantry and the robotic interface, the controllers being configured to position the gantry, attach the robot to the robotic interface, and release the robot from the robotic interface.

The application relates to a wind power equipment installation and transportation ship type and general arrangement, belonging to the technical field of ships and ocean engineering, which comprises a ship bottom, an inner bottom, a main deck and a working deck arranged from bottom to top; a cargo hold for placing wind turbine pile legs is arranged between the inner bottom and the main deck; the working deck has a large opening; an overhanging structure for placing a blade to be installed is arranged on one side of the ship side of the working deck; and a pile holding system which can rotate to lower the pile legs for ship positioning is arranged at the ship side position. The application solves the problem of incoordination of the prior art in different working stages, the efficiency and safety problems during offshore working butt joint, etc., improves the working efficiency, simultaneously reduces the shipbuilding and operation cost, greatly reduces the fuel consumption, and thus reduces the carbon emission.

The invention discloses a positioning and mounting method for an integral stern tube device of a ship, which breaks through the conventional construction method that a main engine can be mounted only after the stern tube device and a stern shaft are mounted, and the main engine is completely hoisted in advance on the premise that a stern post section is not carried, so that the integrity construction progress of an engine room is accelerated, and the construction efficiency is improved. According to the method, the occupied time of a dock is shortened, the shipbuilding efficiency is improved, in the follow-up installation process of the integral stern tube device and the stern shaft, accurate positioning can be conducted on installation of the integral stern tube device and the shaft system based on structural deformation generated by a main engine on a ship body structure automatically, and the shipbuilding efficiency is improved. And the mounting precision and the mounting quality of the integral stern tube device and the shafting are effectively improved.
