The purpose of this paper is to study of the applicability of the current response spectrum analysis method by grasping the dynamic behavior characteristics of soil-pile and pier-crane in pile mooring facilities. To this end, time history analysis was performed using Abaqus as a design variable for various soil types, pile-ground modeling, and structure specific cycles. The results were compared with the analysis results of the response spectrum. Subsequently, a problem has been found in the current response spectrum analysis and the improvements are needed when considering the dynamic behavior of the ground-pile and pier-crane of the pile mooring facility.

The purpose of this paper is to study on the applicability of the standard design response spectrum from the response spectrum analysis method, mainly applied to pile mooring facilities. To this end, after performing the ProShake 1-dimensional site response considering various geological conditions, the current standard design response spectrum was compared, and the ground-pile model in time history and two-dimensional site response analysis using Abaqus were performed to analyze the dynamic behavior of the ground-pile and to examine the selection method of the reference surface of the response spectrum on the installed slope, respectively. As a result, it was confirmed that no problems were found in the applicability of the current standard design response spectrum and no improvements are needed as well when considering the characteristics of the ground-pile dynamic behavior and the slope of the pile mooring facility.

Ocean monitoring facilities are divided into two types, fixed type and floating type. This paper deals with wane load calculation and mooring system for a floating monitoring facility. Wave load and drift forces are calculated for an example case of floating monitoring buoy To enlarge holding power of anchor, circular pile model test was performed. A program for horizontal force of circular pile in sand was made and the calculated result showed fairy good agreement with the result of model test. It is expected that this method will provide good estimation for the holding power of the prototype of circular pile anchor which is relied upon SCUBA activity for installation.
