Main Towing Tanks of National Maritime Research Institute of Japan

Abstract

It is very obvious that drastic improvement of technology for reduction of CO2 emmsion from ocealice going vessels will be required world widely. 400m long towing tank and ice model basin of NMRI are laegest tanks in Japan for each technology area. 400m long towiung tank is testing facility of every kind of vessels from huge oil tanker (VLCC) to 50knots high speed boat. The maximum speed of towing carriage is 15m/sec..
Ice model basin is a model testing facility of ships and offshore structures to be used in ice-covered waters. The basin at NMRI is 35m in length, 6m in width and 1.8m in depth. Recently the basin is used for various research problems including oil spilling in ice and ice loading on ship hulls.
