This summary report presents a condensation of the designs as developed from requirements and concept selection to preliminary design. The study consists of the following six tasks: (1) Design requirements: establish design environmental conditions and criteria. Develop methodology to both assess SKSS reliability and performance, and minimize life cycle costs. (2) Conceptual design: develop at least two SKSS conceptual designs for both barge and spar platform (eight in all). Consider commercial plant SKSS, verify feasibility, define problem areas, estimate life cycle cost. Develop deployment, operation and maintenance scenarios. Recommend an SKSS concept for each platform. (3) Preliminary design; prepare preliminary designs for two SKSS concepts selected by NOAA/DOE. Optimize the designs, provide deployment and retrieval procedures, support requirements, evaute reliability and performance. Assess effects of watch circle and water depth variation. (4) Development and testing recommendations: recommend programs required to confirm design assumptions and performance predictions, including material and component development, and soils investigation. Estimate cost and schedule required to perform these programs. (5) Cost-time analysis: develop a detailed cost and schedule for the acquisition, transportation, deployment, inspection, maintenance, spares, replacement and salvage for the SKSS designs. (6) Commercial plant SKSS recommendations: assess applicability of designs to commercial plant SKSS. Recommend development program and at-sea tests as requied with estimate of cost and schedule.
