PD IEC TS 62600 โ Marine Energy Wave Tidal and Other Water Current Converters Standard Series
Marine Energy โ Wave, Tidal and Other Water Current Converters โ Power Performance, Resource Assessment and Mooring Systems (2012โ2016, UK implementation of IEC/TS 62600)
๐ PD IEC/TS 62600 is the British Standards Institution (BSI) implementation of the IEC/TS 62600 technical specification series on marine energy โ wave, tidal and other water current converters. Marine energy (wave, tidal, ocean/current, thermal gradient and others) is a huge reserve of renewable clean energy, yet the harsh marine environment and the diversity of device prototypes, combined with the lack of unified performance evaluation and testing methods, have seriously constrained industrial development. The series was developed under IEC TC 114 with the involvement of BSI Technical Committee PEL/114 (Marine energy); the ICS classification is 27.140. The seven parts, from wave energy resource assessment and power performance testing to mooring system assessment and power quality, provide systematic technical specifications for the design, testing and grid connection of marine energy converters (MECs/WECs).
๐ก Evaluation challenge of marine energy devices: unlike wind and PV, marine energy resources vary sharply in time (tidal cycles, seasons) and space (water depth, topography), and devices face extreme marine environments. A unified methodology of “resource assessment โ power testing โ mooring assessment” is the basis for comparability and financiability across devices and sites.
1. Background and Design Goals ๐
The marine energy industry long lacked internationally recognized performance metrics: different vendors reported “rated power” and “annual energy production” in different ways, making it hard for investors to compare horizontally and for regulators and grids to supervise. The IEC/TS 62600 series aims to establish transparent, repeatable and comparable evaluation methods for marine energy devices, covering device performance, resource conditions, structural safety and grid-connection interfaces.
The series follows a “resource โ device โ grid” progressive architecture: first assess the site resource (wave energy density, current velocity distribution) and device power performance per Parts 100/101 etc.; then assess the safety of mooring and anchoring systems per Part 10; finally address power quality and system-level requirements per Parts 2/200/201, extending a single device into a complete engineering loop for a generation farm.
โ ๏ธ Four of the seven parts in this series are scanned versions without a full searchable text, including Parts 2, 102, 200 and 201. Descriptions of these parts in this article are compiled from public domain knowledge; always refer to the official BSI published edition for authoritative clauses.

3. Key Technical Requirements ๐ง
3.1 Wave Energy Resource Assessment and Characterization โ Part 101
Part 101 (2015 edition) specifies methods for wave energy resource assessment and characterization, covering resource assessment classes, study planning and data collection (selection, calibration and processing of wave measurement instruments), bathymetry, wave spatial transfer models and measurement data analysis. It defines assessment workflows and quality-control requirements โ the basis for site selection, installed capacity design and energy production forecasting.
3.2 Power Performance Assessment of WECs โ Part 100
Part 100 (2012 edition) provides the power performance assessment method for electricity producing wave energy converters (WECs), specifying test site characterization (wave and current measurement, bathymetric survey, wave spatial transfer model, site modelling), test arrangement, power matrix construction and annual energy production (AEP) computation. It unifies the reporting basis of “under which wave conditions the device outputs how much power”, enabling horizontal comparison of different devices.
3.3 Mooring System Assessment โ Part 10
Part 10 (2015 edition) gives assessment methods for the mooring and anchor systems of marine energy converters (MECs), covering mooring and anchorage system types (spread moorings such as catenary, taut-line and semi-taut-line, etc.), design considerations, safety and risk considerations, analysis procedures and inspection and maintenance requirements. Mooring is the critical structure keeping a marine energy device on station and survivable in harsh sea states; assessing its ultimate loads, fatigue and anchor reliability is essential.
โ
Engineering tip: device selection and site assessment should “match both ways” โ first characterise the resource with Part 101, then verify the device output under typical sea states with Part 100; check mooring design for extreme sea states and fatigue life per Part 10 to avoid “good resource, device cannot stand”.
4. Engineering Practice and Use Cases ๐ญ
- ๐ Site selection and planning: screen candidate sites with the resource assessment methodology, quantify the year-to-year variation of wave/current energy density, and support investment decisions.
- โก Grid connection and power quality: assess device output power quality per the relevant parts, coordinate grid-access review, and determine reactive power compensation and power smoothing schemes.
- ๐ Device development and certification: sea trials at prototype scale report performance curves per the power performance assessment method, providing consistent data for type certification and insurance evaluation.
- ๐ Farm design: extend from single units to arrays (farms), integrating resource, mooring, wake and grid-connection constraints to optimise array layout and collection systems.
5. FAQ โ
โ Q: Why does marine energy need dedicated resource assessment standards instead of meteorological ones?
A: Waves and currents differ from wind/solar irradiance in spatial-temporal variation, measurement instruments (buoys, ADCPs, wave gauges) and energy conversion mechanisms; dedicated characterization and quality-control specifications are needed โ which is exactly what Parts 101/201 provide.

๐ Q: What is the “power matrix” in power performance assessment?
A: The power matrix organises device output power by incident wave/current “state bins” (e.g., wave height ร period, current speed bins); values are statistically derived from measured sea-state data. It is the core tool for estimating annual energy production (AEP) and comparing different devices.

โ Q: What failure modes does mooring assessment focus on?
A: Mainly the ultimate loads of mooring lines and anchors (e.g., 100-year sea state), fatigue damage (long-term wave cycling), redundancy after single-line failure, anchor stability, and installation-phase loads โ all checked with the Part 10 analysis procedure.

๐ Q: New-energy devices are mostly small-batch and diverse; can the standard “manage” them?
A: IEC/TS 62600 aims to unify the “evaluation method” rather than lock in a specific machine type โ whether a wave device is an oscillating water column, point absorber or overtopping type, as long as performance and resource data are reported with the same methodology, comparable and trustworthy results are achieved.
