3D Dimensional Accuracy Management System for Steel Structures

With the development of science and technology, modern buildings are getting taller and taller, and their shapes are becoming more and more unique. The construction difficulty has correspondingly increased, and traditional manufacturing precision detection technology can no longer meet the inspection requirements. Under this circumstance, we introduce 3D precision control technology to achieve 3D precision control of irregular steel structure components, and use a digital simulation system to achieve on-site simulation pre-assembly, so that problems can be predicted and avoided.

IN Series Vessel Precision Management System

In the complex and precise industrial process of shipbuilding, precision data acquisition is undoubtedly a key link in ensuring ship quality and improving production efficiency. The adoption of modern precision data acquisition software, precision analysis and simulation loading software has become an inevitable trend in the industry. Our company successfully developed precision data acquisition and analysis software in 2016 in response to the data acquisition and analysis needs during the shipbuilding process. This software not only improves the efficiency and accuracy of data acquisition, but also provides strong data support for all aspects of shipbuilding through data analysis and processing. From design to production, assembly to quality inspection, every link is made more precise by the application of precision data acquisition and analysis software. The system is introduced below.

Application of container ship simulation and box testing methods

The container ship loading system is an important part of ultra-large container ships. Its installation and submission are directly related to the construction quality and cycle of container ships. The traditional physical test box scheme requires two physical test boxes, self-test box and external lifting box, to ensure the accuracy and success rate of the test box. This is time-consuming and resource-intensive, which restricts the construction speed. In order to further optimize the measurement methods of digital simulation test boxes, a scheme using large-scene 3D point cloud technology to simulate test boxes is proposed to achieve data acquisition and data analysis, and a scheme using computer software technology and AI artificial intelligence technology. Practice has proved that this method not only effectively saves the utilization rate of kinetic energy resources, but also brings a huge efficiency improvement to the test box operation.

On-site pipe measurement and pipe fabrication system

This system uses a dedicated camera and independently developed measuring tools to take close-range photographs and collect the 3D coordinates of the prefabricated pipes; it uses independently developed software and databases for 3D modeling; it outputs ticket diagrams through automatic or manual adjustments; and it uses independently developed four-axis linkage tooling workstations to produce finished pipe sections.

TSMS Real-time Displacement 3D Monitoring System

The TSMS real-time displacement three-dimensional monitoring system consists of a robotic total station, Ethernet communication equipment, tracking monitoring measurement software, and measurement accessories. Its main functions are: it can realize command and data transmission within 600m for 1 to 6 (currently supported) or more (needs customization) robotic total stations; it supports model loading, tracking measurement, data recording, real-time display of position and attitude, and editable and exportable reports.

Application of 3D laser projectors in ship pattern painting

Our company launched a 3D laser projection technology in June 2019. This technology can be applied to scenarios where it is difficult to use traditional methods for paint positioning tasks, such as curved outer plates and complex patterns.

Application of 3D laser scanning technology in ship desulfurization retrofitting

Ship exhaust emissions contain large amounts of particulate matter such as sulfur oxides and nitrogen oxides, and the resulting air pollution has increasingly drawn international attention. The 70th meeting of the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) adopted a resolution to implement a global 0.5% sulfur cap on ship fuel in 2020. The four previously designated Emission Control Areas (ECAs) will continue to have a 0.1% limit. Desulfurization modification areas (from the engine room to the smokestack) have complex environments and limited space. During the design and modification process, it is necessary to obtain the actual spatial conditions and pipeline layout of the engine room. Three-dimensional laser scanning technology, by acquiring dense point cloud data, allows for high-fidelity reproduction of the internal scene, enabling designers to directly use the point cloud data for modification design.

RMS Orbit Detection System

The track precision detection system solves the problem of rapid detection of track straightness, track gauge, and relative height difference of track points. Through automated online detection, it reduces the risk of workers working at heights. Combined with real-time data recording and transmission from a tracking total station, the required data results are calculated, and analysis reports are generated. On-site engineers can use the data analysis reports to guide on-site corrections.

Digital dockyard system

Digital shipyards are one of the important means to achieve lean shipbuilding. Some large shipyards in South Korea and China (such as Dalian Shipbuilding Industry Co., Ltd. and Jiangnan Changxing Shipbuilding Co., Ltd.) have fully established digital shipyards. By making full use of existing software systems such as IN-CHECK, IN-ANALY, GeoYard digital benchmark measurement and control network management software, Adjust3D three-dimensional network adjustment software, and total stations, they have achieved rapid assembly of block sections in the shipyard, semi-ship displacement, and simulated assembly, significantly improving crane utilization efficiency, shortening shipyard cycle, and thus improving economic benefits and production efficiency.

Bearing seat settlement deformation monitoring system

I. Requirement Overview Bearing seat position monitoring system: The actual ship shaft is approximately 100m long. The position of each bearing section in the cabin is measured to monitor the deformation of the bearing seat. A hydrostatic leveling system is considered for monitoring, providing deformation reference data for the bearing seat deformation.

Rapid Measurement System for Ship Deck Flatness

The construction of new vessel types such as 20000TEU container ships and 400KVLOC has placed extremely high demands on the horizontal accuracy of sectional assembly. Due to the larger structural design of newly built vessels, the number of measurement data required for the horizontal bulkhead plane, guide rail installation, and strengthening web installation is relatively large, with higher accuracy requirements and greater difficulty in accuracy control. During the sectional construction process, it is necessary to strengthen the monitoring of accuracy control, strictly monitor the positioning of the sectional base structure, and improve the sectional accuracy by measuring, analyzing, and adjusting the horizontal level of the sections multiple times at each construction stage.
