Offshore engineering equipment (drilling platforms, FPSO floating production storage and offloading units, offshore wind power equipment, subsea pipelines, etc.) operates in marine environments with high salt spray, strong corrosion, and high load, requiring extremely strict structural strength, sealing performance, and anti-corrosion capabilities. Laser technology has been deeply integrated into the entire production and operation and maintenance process of nesting, welding, surface strengthening, marking and traceability, cleaning and repair, becoming the core support for intelligent manufacturing and long-term operation and maintenance of offshore engineering equipment.

1. Laser Welding (Ensuring Structural Safety)

Core structural component welding: Covering the welding of core components such as offshore platform jackets, subsea pipelines, and offshore wind power towers, high-power laser welding technology is adopted, suitable for thick plate high-strength steel. It has high weld strength, corrosion resistance and fatigue resistance, and excellent sealing performance, meeting the long-term use requirements of harsh marine environments, while improving welding efficiency and shortening the construction cycle.

2. Laser Cutting (Precision Nesting, Adapting to Complex Structures)

• Large structural component nesting: Cutting of thick plates and large-format sheets (up to 12m+) for large equipment such as offshore platforms and wind power towers, suitable for materials such as carbon steel, high-strength steel, and weathering steel, with an accuracy of ±0.1mm. It supports cutting of complex special-shaped parts and integrated bevel cutting, reducing subsequent processing procedures and improving material utilization by 15%+.

• Pipeline/profile cutting: 3D laser cutting of pipes and profiles such as subsea pipelines, platform supports, and wind power tower accessories, adapting to complex curved surface and multi-angle cutting requirements. The cutting edge is smooth and burr-free, no subsequent grinding is required, and it can be directly butt-welded to improve assembly efficiency.

Precision component cutting: Laser cutting of small precision components such as seals, connectors, and sensor housings of offshore engineering equipment, with high precision and flat cutting edges, meeting the requirements of precision assembly and sealing, and adapting to the strict use standards of marine environments.

3. Laser Marking (Full-Lifecycle Traceability and Supervision)

• Large structural component marking: Printing equipment numbers, batch information, QR codes, and anti-corrosion grade marks on core structural components such as offshore platform pile legs, jackets, and wind power towers, which are wear-resistant, salt-spray-resistant, and never fall off. It realizes the full-process traceability of equipment from production, transportation, installation to operation and maintenance, meeting the supervision and quality assurance requirements of the offshore engineering industry.

• Pipeline and component marking: Marking part numbers, production dates, quality inspection information, and operation and maintenance records on subsea pipelines, hydraulic components, electrical components, etc., supporting underwater identifiable marks, facilitating quick positioning and troubleshooting during offshore operation and maintenance, and improving operation and maintenance efficiency.

• Anti-corrosion layer marking: Printing anti-corrosion grade, construction date and other information on the surface of the equipment anti-corrosion layer, the mark is clear and does not damage the anti-corrosion layer, ensuring the anti-corrosion performance of the equipment, and facilitating later anti-corrosion maintenance and testing.

4. Laser Surface Treatment (Strengthening Performance, Extending Service Life)

• Laser cleaning: Removing rust, scale, and oil from the surface of plates before welding, replacing traditional pickling and grinding processes, which is environmentally friendly and free of secondary pollution, greatly improving weld quality and anti-corrosion layer adhesion; it is also used to clean marine organisms, salt scale, and old paint layers on the equipment surface during offshore operation and maintenance, preparing for anti-corrosion maintenance.

• Laser hardening/cladding (strengthening and repair): Surface strengthening of key components such as offshore platform pile legs, jackets, and wind power tower flanges, increasing hardness by 2-3 times, significantly enhancing wear resistance, corrosion resistance, and fatigue resistance, extending the offshore service life of the equipment; it can also be used for repairing worn and corroded components, and the performance after repair meets the standard of new components, reducing operation and maintenance costs by 50%+.

• Laser anti-corrosion pretreatment: Laser texture processing on the equipment surface to improve the adhesion of the anti-corrosion coating, avoid coating peeling, adapt to the high-salt spray and strong-corrosion marine environment, and further extend the anti-corrosion life of the equipment.

Key Benefits

• High reliability: Laser welding and strengthening processes greatly improve the structural strength, corrosion resistance, and fatigue resistance of equipment, adapting to harsh marine environments and reducing equipment failure and operation and maintenance risks.

• High precision: ±0.1mm cutting and welding accuracy meets the assembly and sealing requirements of complex structures of offshore engineering equipment, reducing rework rate and ensuring equipment operation safety.

• High efficiency: High-speed cutting of thick plates, one-step bevel forming, and automated welding greatly shorten the production and offshore installation cycles of large equipment, reducing labor and construction costs.

• Green and long-term: Laser cleaning replaces traditional polluting processes, and laser repair realizes the reuse of waste components, which is both environmentally friendly and reduces operation and maintenance costs, helping the green and long-term operation and maintenance of offshore engineering equipment.
