As a partner accompanying MICO and PTSC Thanh Hoa from the early days of implementing the colossal wind turbine base construction solution, Weldcom had the opportunity to prove its capabilities and contribute to the project’s outstanding completion.
In early October 2023, PTSC Thanh Hoa successfully fabricated the first three wind turbine bases out of a total of 30 bases for the Greater Changhua 2b & 4 offshore wind power project, with PTSC serving as the general contractor.
The production of all 30 bases is expected to be completed by February 2024, eight months ahead of the project schedule. This achievement is the result of thorough preparation by PTSC and its partners in devising an efficient production and construction plan and investing in appropriate machinery and equipment for the 6-hectare fabrication yard.
Each base weighs 300 tons, stands 15 meters tall, and has a diameter of up to 14 meters. This is one of the most challenging structures of the project, requiring a special production process to meet the investor’s stringent quality standards.
After careful consideration and evaluation of the feasibility and ability of suppliers to meet the construction schedule, PTSC accepted the super welding gantry installation solution proposed by Weldcom and MICO and promptly implemented it. Each welding gantry stands 20 meters tall, can move within a 30-meter range on a 100-meter long rail, and is capable of welding pipes ranging in size from 4 to 14 meters.
The first three wind turbine bases were completed, each weighing 300 tons, standing 15 meters tall, and with a diameter of 14 meters.
Mr. Tran Viet Cuong, the director of the Weldcom factory, stated that this is the largest welding gantry in Vietnam, entirely developed, designed, and constructed by Vietnamese professionals. The entire production and assembly process took only four months, during which Weldcom’s team of design, fabrication, and operational engineers worked continuously to meet the schedule committed to PTSC Thanh Hoa.
He also shared that, despite mastering 100% of the welding technology and being confident with the experience of manufacturing hundreds of welding gantries, Weldcom’s solution experts still faced numerous challenges in this project. These difficulties were due to the impact of weather conditions at the construction site, such as prolonged heat, storms, average wind speeds of levels 6 and 7, and high salinity and humidity in the air.
Mr. Tran Viet Cuong shared the challenges faced during the design, construction, and installation of the welding gantry.Overcoming these hardships, the trio of Weldcom’s massive welding gantries proudly stood at the center of the fabrication yard and played a significant role in the project’s early completion. They left a strong impression and confirmed the capabilities of Vietnamese contractors in the offshore wind power sector.”I can sense the growth of each team member after participating in this project. Everyone continuously learned, expanded their knowledge, and improved their skills, pushing beyond their own limits. Compared to the initial concerns when we first took on the project, the team is now fully confident in handling similar, even more challenging projects,” Mr. Cuong remarked.
The entire solution, including production, installation, and operation, was carried out by Vietnamese professionals.
Not only on an individual level but also through the development of a complete solution for a pioneering product in Vietnam that meets international quality standards, Weldcom has demonstrated its strength and capabilities. From designing and fabricating to installing and operating the welding gantry for PTSC Thanh Hoa’s wind turbine base project, Weldcom has shown its mastery of technology and its ability to produce heavy steel structure fabrication equipment.
This product also marks a milestone in Weldcom’s growth and solidifies its leading position in providing comprehensive solutions, thereby enhancing its reputation as a top-tier technology contractor in Vietnam’s and the region’s mechanical engineering industry. Weldcom has become a trusted strategic partner for clients and partners both domestically and internationally.
