To establish basic technology for design and construction of a new type
superhigh-speed ship, Techno Super Liner (TSL), the experiment using a model
ship was launched on the ocean in July 1994.
Research and development of TSL started in 1989 aiming at more advanced
marine transportation and the enhanced potential of creative technology in shipbuilding.
The development goal is to achieve a speed of more than 50 knots (about 93 kilometers
per hour), a loading capacity of more than 1,000 tons, a cruising range of more
than 500 nautical miles (about 930 km), as well as the capability to run even
on rough seas.
The experiment used two pilot model ships: "Hisho" (about 70 meters long),
an air pressure combined type ship, and "Hayate" (about 17 meters long), a lift
combined type ship. The experiment was conducted to verify and evaluate study
results concerning element technology, such as ship type performance, structural
strength, new material, propulsion machinery, and attitude control systems,
under the actual ocean conditions.
The previous tests indicate that favorable results have been achieved. For
example, a speed exceeding the plan has been recorded. The Ministry of Transport
pursues research and development to establish basic technology so that TSL can
be put to practical use in late 1990s. At the same time, the Ministry is studying
which harbours are suitable for TSL and how to carry out business by TSL.
