[Vol. 1] A recent trend in the marine industry is that manufacturers are striving to quickly develop eco-friendly devices. Nakashima Propeller manufactures marine propellers for domestic and international shipbuilders. They are also actively involved in developing and manufacturing energy saving propellers and appendages. Software Cradle’s SC/Tetra has been an indispensable tool for their development.
Nakashima Propeller, a manufacturer of marine propellers, celebrated its 90th anniversary in 2016. They are one of the dominant firms in the industry, holding 80% of the domestic Japanese market share and 30% of the overseas market. Their products are used by shipbuilders across the globe, including Japan, China and Korea.
“Three types of technical capabilities are needed to develop marine propellers: these are, fluid analysis, casting, and machining,” explains Mr. Nobuhiro Hasuike from Nakashima Propeller, Deputy General Manager, Propeller and Pod Propulsion Performance Section, Propeller Design Dept., Engineering Division (Picture 1, on the right). Propellers are manufactured through build-to-order production. Each product is designed to perform best when implemented in the assigned ship. At the end of the manufacturing production process, propeller blade surfaces are neatly polished by experts, who are capable of detecting errors down to one hundredth of a millimeter. Being highly recognized for their skills and technologies, Nakashima Propeller received the Prime Minister’s Award of First Monozukuri Japan Grand Prix. They were also one of the first companies in the industry to successfully manufacture carbon fiber reinforced plastic (CFRP) propellers. They received another Prime Minister’s Award of Sixth Monozukuri Japan Grand Prix for their CFRP propellers (Picture 3).
The entire marine industry has the goal of satisfying the Energy Efficiency Design Index (EEDI), the guidelines by the International Maritime Organization (IMO) for the purpose of GHG reduction. Regulations will be gradually reinforced, and ships will have to satisfy the requirements to continue sailing. “We are intending to contribute to GHG reduction through developing energy efficient propellers that help improve the performance of the entire ship,” says Mr. Akinori Okazaki of Nakashima Propeller, Deputy Manager, Propeller and Pod Propulsion Performance Section, Propeller Design Dept., Engineering Division (Picture 1, on the left).
