Full title and description

IEC/TS 62600-2:2019 — Marine energy — Wave, tidal and other water current converters — Part 2: Marine energy systems — Design requirements. This Technical Specification sets out engineering and design requirements intended to ensure the structural, mechanical, electrical and control integrity of marine energy converters (MECs) — including wave, tidal and other water-current devices — under site-specific environmental and operational conditions.

Abstract

IEC/TS 62600-2:2019 provides a limit-state, risk-informed framework for the design of MEC main structures, appendages, seabed interfaces, moorings and associated mechanical and electrical subsystems. It defines design conditions, design categories (normal, extreme, abnormal and transport), and limit states (serviceability, ultimate, fatigue and accidental), and gives requirements and safety factors to reduce the probability of catastrophic failure for devices that are unmanned during operation. The document is targeted at ensuring device viability for a stated design life across floating, fixed-to-seabed and shore-connected configurations.

Scope

This Technical Specification applies to the design of marine energy systems (MECs) used to convert wave, tidal and other water current energy into electrical power. It addresses the structural and system-level requirements necessary to resist environmental loads and operational actions for floating and fixed devices and for devices that are unmanned during operational periods. Topics covered include definition of design conditions and categories, selection of limit states, load and failure-case development, design life and safety factors, interaction of structural, mechanical and electrical subsystems with the seabed and mooring systems, and basic requirements to limit the consequences of accidental events.

Key topics and requirements

• Limit-state design methodology (serviceability, ultimate, fatigue, accidental).
• Definition of design conditions and operational modes (normal operation, operation with fault, parked, transport).
• Design categories and required safety levels (normal, extreme, abnormal, transport).
• Requirements for main structure, appendages and seabed/foundation interfaces (including moorings and anchors).
• Mechanical and electrical subsystem requirements as they affect structural viability and system integrity.
• Fatigue assessment and cumulative damage considerations for long-term survivability.
• Material, corrosion and environmental degradation considerations for marine exposures.
• Mandatory consideration of failure consequences and design measures to reduce probability of catastrophic failure.
• Provisions for inspection, verification and documentation to support design claims and certification.

Typical use and users

This specification is used by device designers and structural/mechanical/electrical engineers working on development and certification of wave, tidal and other water-current energy converters; test houses and laboratories validating structural models; certification bodies and regulators assessing design robustness; project developers and owners assessing technical risk; insurers performing underwriting; and standards committees aligning device requirements across the sector.
