Ocean Thermal Energy Conversion (OTEC) Systems

PT 62600-20: Guideline for design assessment of Ocean Thermal Energy Conversion (OTEC) systems

Objective: Ocean Thermal Energy Conversion (OTEC) uses temperature difference ( generally of about 20 degree C)  between the upper and deep  layers of ocean to generate  stable  base load electrical power.  Potential power production decreases as the temperature difference drops and increases as the temperature difference increases. OTEC is a major portion of the recently reported global ocean energy resource ( Ref: IPCC SRREN, 2011). Some of the key components of the OTEC systems are:  Types of conversion cycle ( close, open or hybrid), platform type ( floating or land based), cold water pipe design, connection between platform and cold water pipe,  warm water ducting, heat exchanger, condenser, turbo-generator. OTEC technologies are being researched and developed  in Europe, America, and Asia. Currently, significant OTEC related project activities are underway in US, Japan, India, Korea, and other parts of the world.  Considering the large OTEC resource potential  and the current  active technology development & commercialization activities, an unified  relevant international  design specification is needed to enable  realization of the global opportunity  for  generation of  renewable  electricity as well as for energy efficiency application.

Scope: Scope of this new work item proposal is focused on developing a technical specification on how to design and to assess the structural safety of an OTEC plant for floating and land-based applications to generate electricity. Considering the similarity, the proposed specification is also intended to be applicable to ocean thermal air-conditioning system.
