Ship Production Lecture 12 – Shipbuilding in Japan Historical Factors: 1950s 60s rapid growth in Japanese commercial shipbuilding industry. Rapid technological advances in both ship design construction – demand for increasingly large tankers. Increased international competition. Formation of Seven Major shipbuilding companies through mergers. Shipbuilding markets collapsed in 1973 due to oil crisis (Yon Kippur War). Historical Factors: Large tanker market evaporated. Bulk carrier deliveries dropped by 74% by 1979. Late 1970s early 80s restructuring of industry leaving medium sized shipbuilders with half of Japanese output. Technological development slowed by early 1990s. Product innovation superceded by production cost control, so industry movement to maturity favoured cost competitiveness. Japanese Shipyards: Japanese Shipyards: • Covered shops for steel fabrication. • Outdoor platens for grand block assembly. • A large, open building block. • Very heavy cranes for lifting grand blocks into the erection dock. Optimised for construction of large merchant ships from heavy, preoutfitted hull blocks. Large open drydock allows lower-level products to be efficiently assembled into a wide variety of ship types.

These vessels form backbone of Japanese shipbuilding industry’s business base. Can Japanese industry maintain competitiveness considering heavy exposure to volume product markets (compared with niche technological markets – cruise ships, FPSOs)? Japanese Shipbuilding Industry: “As to whether or not the
