Abstract:
Petroleum is the main source of energy in the world. So, exploration and production of this strategic matter from earth and sea has a major importance. A large amount of this black gold is hidden under deep seas floors and extraction of these sources requires knowledge of design and technology of construction of deep water offshore platforms and equipments. Convetional Tension Leg Platform (CTLP), configured as 4 cloumns and 4 pontoons, is one of deep offshore platforms moored by several pretensioned tethers. The dynamic behavior characteristics of CTLPs are extracted in this thesis by numerical modeling of CTLP and regular wave interaction. A computer program PARADISE is developed in MATLAB to calculate Hydrodynamic coefficients and loads using Boundary Element Method (BEM) and extract time history of motions using Modified Euler Method (MEM)
