Energy Savings Devices News

NYK Stolt Tankers, a joint venture between NYK Line and Stolt Tankers, has placed an order with Nantong Xiangyu Shipyard in China to build six 38,000 deadweight tonne stainless steel chemical tankers for delivery between late 2026 and 2029.The newbuilds will be sisters to a series of six vessels Stolt Tankers ordered at Wuhu Shipyard in November. The ships feature 30 cargo tanks, offering a range of cargo flexibility and are designed to maximize fuel efficiency using a wide range of energy savings devices and shore power connection, Stolt Tankers said.

Considerable effort, particularly following the oil embargo of the 1970s, has been placed on reducing the fuel oil consumption of ships, a task readily handled by a series of improvements in hull shapes, the fitting of energy savings devices, and improvements to the performance of main engines. A group of engineers from the Tsu Research Laboratories — Koichiro Matsumoto, Kazuyoshi Hirota and Kenji Takagishi - however, noted that while performance in still water was gaining, other factors, namely wave resistance was taking its toll. Thus a study was launched to develop new ship shapes in order to reduce the resistance increase due to waves, in order to lower sea margin. NKK Corp.
