ABSTRACT
Severe
wind-wave due to tropical cyclone Linda can cause port downtime which affects port
operations such as berthing, mooring and (un)loading of the ship. The ship motions are criteria for limiting
the port operations, human safety and preventing the damage of port equipment and
furniture. Therefore, this study discusses moored
ship motions due to severe wind-wave during the tropical cyclone Linda which entered
the Gulf of Thailand in November 1997. The ship motions are represented in the moored
ship analysis at SRH (Sriracha Harbour Port) and BLCP (BLCP Coal-Fired
Power Plant Port), and are subject to the static
environmental load on the ship in accordance with Spanish Standard (ROM 0.2-1990)
[1]. The environment in numerical model is derived from the wave model and hydrodynamics
model using the application of Delft3D-WAVE and Delft3D-FLOW. The model location
includes Ao Udom Bay and Rayong Sea. The model
results represent the environment at Rayong
Sea which is more severe than Ao Udom Bay. The ship motions at BLCP are mostly larger
than SRH.
KEYWORDS
