Definition of the Requirements of a Station Keeping Subsystem (SKSS) Engineering Evaluation Tool (SKEET). Final Report

摘要

A study of the requirements of an OTEC Station Keeping Subsystem (SKSS) Engineering Evaluation TOOL (SKEET) has been completed by Hoffman Maritime Consultants Inc. SKEET is intended to provide a basis for quantitative comparison and assessment of candidate SKSS performance based on realistic predictions of expected loads, motions and displacements obtained by modeling all significant environmental and operational factors. The objectives of the study are: to define the required elements of a SKEET, and to assess the state of the art of technology related to SKEET. The results provide a technical basis for decisions regarding the planning, acquisition and implementation of a SKEET. It is noted that selection of specific analytical methods to be incorporated in SKEET is beyond the scope of the present study. The requirements for formulation of a SKEET, based on supporting documentation provided in separate volumes, are summarized. The results of the study have shown that: existing technology and methods of analysis are adequate to fulfill the basic requirements of SKEET, except that further validation is required for methods of predicting second order wave drift forces for cases other than ship in beam seas. Therefore, it is concluded that: development of a SKEET is essentially a process of selection, adaptation, integration and validation; and that a basic SKEET capability could be achieved within a one year period.
