Full title and description

IEC TS 62600-20:2019 — Marine energy — Wave, tidal, and other water current converters — Part 20: Design and analysis of an Ocean Thermal Energy Conversion (OTEC) plant — General guidance. This Technical Specification gives general principles and guidance for the design assessment of OTEC plants (land‑based, shelf‑mounted and floating), with emphasis on marine-specific components such as warm and cold water intake systems and interfaces to the electrical export system.

Abstract

Provides guidance for assessing design and performance of Ocean Thermal Energy Conversion plants intended for stable power generation and related energy carriers. It identifies OTEC‑specific design drivers, intake and discharge systems, key interfaces to conventional power‑plant elements and references established standards for non‑unique components.

Scope

Establishes general principles for design assessment of OTEC plants for electricity and other energy carriers. Applicable to onshore (land‑based), shelf‑mounted (nearshore seabed) and floating OTEC systems; for land‑based systems the scope ends at the main power export cable suitable for grid connection, and for shelf‑mounted and floating systems normally at the main power export cable connection to the electrical grid. The document focuses on OTEC‑specific marine aspects (noting that many common components should follow established power‑plant and offshore standards referenced in the text).

Key topics and requirements

• Design and assessment principles for OTEC power plants, including performance drivers and resource considerations.
• Requirements and guidance for warm and cold water intake and discharge systems specific to OTEC.
• Classification of system types: land‑based, shelf‑mounted and floating, and boundaries for design responsibility (e.g., power export cable interface).
• Consideration of marine environmental factors, operational steadiness of thermal resource, and site selection impacts on design.
• Interfaces to conventional power‑plant components and recommendations to apply existing standards for non‑unique equipment.
• Guidance on risk assessment, reliability, testing and verification relevant to OTEC systems.
• Cross‑references to industry codes and standards for structural, mechanical, electrical and offshore systems.

Typical use and users

Intended for OTEC project developers, system and marine engineers, financiers and investors, manufacturers, regulators and permitting authorities. It is used during conceptual and detailed design phases to inform technical due diligence, risk assessment and to define interfaces between marine systems and conventional power‑plant elements.

Related standards

Part of the IEC 62600 series on marine energy (other parts cover wave, tidal and other converters). The Technical Specification also references numerous offshore and power‑plant standards and guidance (examples include relevant ISO 19901 series, ISO 13628, IEC 60079‑0 where applicable, and industry guidance such as DNV/GL and API documents) for components and practices not unique to OTEC design.
