Megaunity’s ventilation system is applied to the H1508 Projectof Shanghai Waigaoqiao

It is a key strategy for the nation to develop the capacity to independently design and build large cruise ships, which is also imperative for transforming and upgrading the shipbuilding industry of China. Building a large cruise ship is a massive project. It requires the comprehensive capability to design the systems that are enabled by complicated technology and manage the building processes that are executed in more rigid schedules and controlled with more stringent mechanisms. The same is true for the design of ship’s air duct system, which is challenged by complicated technology, high design and manufacturing requirements, and a tight project schedule. With its qualifications, professional design capability, and extensive experience, Megaunity became the EPC turnkey contractor for the ship-wide air duct systems of the H1508 Project. It was responsible for the design and production of the ship-wide ventilation systems, as well as the supply, installation and commissioning of the air ducts. 


The capability to build the large cruise ships, known as the “crown jewel” of the shipbuilding industry, represents the mastery of all the relevant shipbuilding technologies. China’s first large cruise shipbuilding project, H1508, is of great significance, demonstrating that China’s shipbuilding industry is reaching for the “last shining jewel in the crown”. Since the official commencement of steel cutting operation on October 18, 2019, Waigaoqiao Shipbuilding has repeatedly showcased the “Chinese power”. Under the plan, China’s first large cruise ship will undock in the first half of 2023 and be completed and delivered in 2023. (Information source: Pudong News)
