PROBLEMS OF LARGE VESSELS IN SHALLOW WATER

The problems encountered by large vessels, of over 100,000 dwt, in shallow water, are discussed. The effect of squat on these vessels becomes more pronounced when the under keel depth is less than 50 per cent of the ship's draft, and the greater the ship speed, the greater the squat. Other shallow water effects in situations such as crash stops, and effects on steering and bank suction, are also discussed in the article. The author concludes that the installation of additional maneuvering devices such as bow thrusters, and even the adoption of twin-screw configurations, might be worthwhile for the safety of these large ships.
