Title: OTEC platform configuration and integration. Volume II. Technical concept. Final report

Abstract

The configuration, integration, and evaluation studies performed in the first phase of this contract resulted in a ranking of the most feasible platform candidates for commercial OTEC applications. On the basis of the results obtained from three individual contractors performing the same study, the Department of Energy made selections of two platform hulls for each contractor for conceptual designs. For Phase-II studies, M. Rosenblatt and Son, Inc. (MR and S) project team was given the SPAR and SPHERE platforms to perform not only conceptual designs for, but also cost and time schedules and sensitivity analyses. This is the second volume of a three-volume MR and S report, and it presents the results of conceptual designs for the two platforms, the facilities and equipment required for construction, deployment, and operation of these platforms, and cost estimates and time schedules. All conceptual design work is performed for the baseline site on West Coast of Florida. The cost differentials and other considerations involved with deploying the platforms in the New Orleans and Puerto Rico sites are also presented. As an end product of the complete study, the costs for the SPAR and the SPHERE platforms are reported both in terms of acquisition costsmore » in 1978 dollars and life cycle costs in dollars per kilowatt.« less

  • The purpose of this project is to evaluate six candidate hullforms as candidates for the OTEC commercial plant. This volume is a summary of the conceptual design including facility requirements, cost, schedule, and site sensitivity. Two OTEC commercial plant configurations are considered in this study: the ship and the semi-submersible. Engineering drawings are presented. (WHR)

  • Detailed information and conceptual design drawings for the SPAR and SPHERE platforms for an OTEC commercial plant are presented. A work breakdown structure and a detailed estimate of the SPAR platform weight are included. (WHK)

  • The economic success of an Ocean Thermal Energy Conversion (OTEC) system is highly dependent on a platform which provides adequate support for the power system, accommodates reliably the cold water pipe, and is most cost effective. The results of a study conducted for the Department of Energy to assess six generic types of platforms to determine the most satisfactory platform for severl potential sites are presented. The six platform configurations are ship, circular barge, semi-submersible, Tuned Sphere, submersible, and spar. These represent directional and symmetric types of platforms which operate on the surface, at the interface, and submerged. The fivemore » sites for this study were primarily New Orleans, Keahole Point (Hawaii), Brazil, and secondarily Key West and Puerto Rico. Electrical transmission of energy by submarine cable is the planned form of energy transmission for all sites except Brazil, where chemical conversion is to be the method of transmission. This study is devoted to the platform (or ocean systems) of the OTEC plant which is chiefly comprised of the hull and structure, the seawater system, the position control system, and miscellaneous support/assembly systems. The principal elements in the work breakdown structure for the commercial plants are presented. The assessment of the six platform configurations was conducted utilizing a baseline plan (100-MW(e) (Net)) and site (New Orleans) with variations from the baseline to cover the range of interested platforms and sites.« less

  • The overall purpose of this project is the conceptual design of two OTEC commercial plants. This report presents results of task VII: a plan for the development of an OTEC Demonstration Plant including funding, key milestones, fallbacks, etc. Studies include a risk assessment survey, OTEC Demonstration Plant ocean systems requirements, OTEC Demonstration plant power and transmission system requirements, electric utility survey, market assessment, and a demonstration plan. (WHK)

  • Studies leading to the development of two 400 MW Offshore Thermal Energy Conversion Commercial Plants are presented. This volume includes a summary of three tasks: task IIA--systems evaluation and requirements; task IIB--evaluation plan; task III--technology review; and task IV--systems integration evaluation. Task IIA includes the definition of top level requirements and an assessment of factors critical to the selection of hull configuration and size, quantification of payload requirements and characteristics, and sensitivity of system characteristics to site selection. Task IIB includes development of a methodology for systematically evaluating the candidate hullforms, based on interrelationships and priorities developed during task IIA.more » Task III includes the assessment of current technology and identification of deficiencies in relation to OTEC requirements and the development of plans to correct such deficiencies. Task IV involves the formal evaluation of the six candidate hullforms in relation to sit and plant capacity to quantify cost/size/capability relationships, leading to selection of an optimum commercial plant.
