In normal state, FPSO is moored in its operation sea area for a long time by single-point mooring, which is turning with single-point due to environmental loading such as wind, current and waves.

Nonlinear finite element analysis on seismic behavior of two kinds of slabs under cyclic load;

Experimental study on composite slabs under cyclic load;

In order to study the elas to plastic response of the beam to column welded connection under the seismic load and improve the earthquake resistant performance of welded joint,the non linear FEM analysis of "H" and "Dog Bone" Type of welded connection under the simulating seismic cyclic load was carried out by utilizing the ANSYS programming package.
