BUTTING China in collaboration with BUTTING Anlagenbau in Schwedt has constructed and delivered several large vessels and pipes for the retention period in a bio-diesel plant. With a diameter of more than 5m and more than 18m high, the so-called “Big Bertha” is the largest vessel delivered to this bio-diesel plant in Hong Kong. The size of the vessel made transporting it a challenge. The journey of around 1200km from the factory in Shanghai to the construction site in Hong Kong began on a lorry. Then the next stage went by the waters of the Yangtse river from the nearby port of Shanghai. From the river, the load had to be transported across the Yellow Sea to Hong Kong, then unloaded again in the harbour there. Because of the construction situation there, no transport ships are used, only barques, and it took the vessels a week to reach their destination. As well as “Big Bertha”, four smaller columns, the largest 15m high, and with 12m stainless steel pipes made of material 316L, weighing more than 30tns, were delivered to the construction site in Hong Kong.
