Bureau Veritas Marine & Offshore (BV) recently completed a significant project by delivering the CMA CGM Tiga, the final vessel in a series of ten 5,500 TEU container ships built for CMA CGM at CSSC Qingdao Beihai Shipbuilding. This project showcased BV’s classification services and Bureau Veritas Solutions M&O’s advisory services, which played a crucial role in ensuring compliance with international safety, structural integrity, and environmental protection standards while maximizing performance.
The CMA CGM Tiga is a new-generation medium-sized container ship that was designed by CSSC Qingdao Beihai Shipbuilding in collaboration with Shanghai Ship Research & Design Institute (SDARI). Measuring 255.5 meters in length, 40.0 meters in width, and boasting a deadweight tonnage of 73,025.91 tons, the vessel incorporates cutting-edge technologies such as the world’s first WinGD7X82-2.0 main engine, Selective Catalytic Reduction (SCR) system, and Alternate Maritime Power (AMP) systems. These advanced technologies significantly reduce sulfur oxide (SOx) and nitrogen oxide (NOx) emissions, aligning with environmental protection requirements.
BV played a pivotal role in providing classification services for the CMA CGM Tiga, collaborating closely with CMA CGM, CSSC Qingdao Beihai Shipbuilding, China Shipbuilding Trading Co., Ltd. (CSTC), and the engine manufacturer. BV supported the success of the series by offering design support, plan approval to BV classification rules, statutory requirements, and survey under construction services.
Bureau Veritas Solutions M&O’s advisory services expertise was instrumental in optimizing each ship’s energy efficiency and performance. The series achieved an Energy Efficiency Design Index (EEDI) that was 53.6% below the baseline, surpassing IMO Phase III standards for environmental performance. BVS contributed to the design and operational efficiency of the series by providing advisory services, including springing vibration analysis in a global finite element model and reducing design cycles. Additionally, BVS supported structural integrity and ensured timely steel procurement.
Furthermore, BV conducted full-process precision monitoring to ensure that the vessels met the required standards. This included passing container hold tests and complying with hull welding quality standards. Safety features such as the Fuel Oil Rapid Recovery System (FORS) notation and an insulation fault alarm and positioning system for low-voltage refrigerated container circuits were incorporated to enhance operational safety and efficiency. The FORS notation enables swift fuel recovery from tanks in emergencies, while considerations for elastic deformation of large hull structures were factored into shaft alignment calculations to prevent propeller shaft and bearing wear.
Overall, the successful completion of the CMA CGM Tiga and the entire series of container ships underscores BV’s commitment to excellence in providing classification services and BVS’s expertise in advisory services. These vessels not only meet international standards for safety, structural integrity, and environmental protection but also showcase superior performance and energy efficiency. BV and BVS’s collaborative efforts have contributed to the success of this project, demonstrating their dedication to supporting the maritime industry’s advancements in technology and sustainability.
