DESIGN OF SCOUR PROTECTION AROUND COOLING WATER OUTLET AT THE SEA BOTTOM USING 3-D WAVE SIMULATION

Abstract

 The design method of scour protection around the cooling water outlet was shown with the example of an outlet which will be constructed at the sea bottom in front of the Ishikariwan-Shinko LNG power plant. The combination of 2-D and 3-D wave simulation using CADMAS-SURF gave the flow distribution and maximum flow velocity around the outlet. The covering blocks should be put on the area where the flow is accelerated by the existence of the outlet. The Isbash's equation showed the required weight of the covering blocks.
