Standards
This page last reviewed on January 29, 2025
A standard is a document that has been developed through the consensus of experts; is approved and published by a recognized body; and comprises rules, guidelines, processes, or characteristics that allow users to achieve the same outcome. Standards can be international, national, or industry-specific and reflect agreements on the technical description of the characteristics to be fulfilled by the product, system, service or object in question. They are widely adopted at the regional or national level and are applied by manufacturers, trade organizations, purchasers, consumers, testing laboratories, governments, regulators and other interested parties. Not yet a standard, a technical specification approaches a standard in terms of detail and completeness but has not yet passed through all approval stages. The International Electrotechnical Commission (the IEC) is the working body developing international standards for marine energy applications.
International Electrotechnical Commission (IEC)
The International Electrotechnical Commission (IEC) , founded in 1906, is a global not-for-profit membership organization whose work underpins standards, quality infrastructure, and international trade in electrical and electronic goods. Their work facilitates technical innovation, affordable infrastructure development, efficient and sustainable energy access, smart urbanization and transportation systems, climate change mitigation, and increases the safety of people and the environment. The IEC brings together more than 170 countries and provides a global, neutral and independent standardization platform to 20,000 experts globally. It administers 4 Conformity assessment systems whose members certify that devices, systems, installations, services and people work as required. IEC work directly underpins the targets of all 17 UN Sustainable Development Goals.
IEC TC-114
IEC TC-114 is a Technical Committee (TC) that develops and manages standards for the Global Marine Energy Industry
IEC TC-114 was created in 2007 to establish, maintain and publish technical standards and guidelines which are used by a wide range of stakeholders in the marine energy industry. At present, 30 member countries participate in activities of TC-114 of which 18 are Participating (P) members with full voting privileges and 12 are Observing (O) members. The United States is a Participating member of TC-114 and its membership activities are directed by its National Committee (USNC), at the American National Standards Institute (ANSI). To manage its participation in TC-114, ANSI established a Technical Advisory Group (TAG) which coordinates the activities of approximately 100 TAG members who volunteer their time to participate on the U.S. committees. They help develop technical standards associated with TC-114’s Maintenance Teams (MT), Project Team (PT), Ad-Hoc groups (AHG), and Advisory Groups (AG). Certain TAG members serve as subject matter experts (SME) which means that they are the official representatives of the United States on the various Working Groups.
The US TAG would like to acknowledge the generous support of the U.S. Department of Energy’s Water Power Program which enables it to effectively manage a wide range of TAG activities including disseminating information to the general public. If you are interested in becoming a member of the US TAG and joining one of its committees, follow the link below, read the information contained under the Standards Development tab carefully and communicate your interest via email on the Contact page.

IEC TC-114 Leadership and Scope
The International Electrotechnical Commission Technical Committee 114 (IEC TC-114) was formally established by the IEC in 2007 and held its inaugural plenary meeting in May 2008 in Ottawa, Canada. The current TC-114 leadership team is as follows:
- Chairman: Mr. Jonathan Colby of the United States
- Secretariat: National Committee of the United Kingdom
- Secretary: Mr. Danny Peacock (British Standards Institute)
- Technical Officer: Mr Anson Chiah (IEC)
The mission and scope of TC-114 was defined during the first plenary session and is as follows: “To prepare international standards for marine energy conversion systems. The primary focus will be on conversion of wave, tidal and other water current energy into electrical energy, although other conversion methods, systems and products are included. Tidal barrage and dam installations, as covered by TC-4, are excluded.”
More information on the TC-114 Strategic Business Plan and Good Working Practices within the Technical Committee can be downloaded from the TC-114 Dashboard .
TC-114 establishes Project Teams (PT), ad-Hoc Groups (AHG), Maintenance Teams (MT) and liaisons with other IEC Technical Committees as needed. TC-114 has the following formal liaisons:
- IECRE - IEC System for Certification to Standards Relating to Equipment for Use in Renewable Energy Applications
- IEC TC 4 - Hydraulic turbines
- IEC TC 8 - System aspects of electrical energy supply
- IEC TC 8/SC 8A - Grid Integration of Renewable Energy Generation
- IEC TC 8/SC 8B - Decentralized electrical energy systems
- IEC TC 56 - Dependability
- IEC TC 82 - Solar photovoltaic energy systems
- IEC TC 88 - Wind energy generation systems
- ISO/IEC JTC 1/SC 41- Internet of Things and Digital Twin
- ISO/TC 43/SC 3 - Underwater acoustics
- ISO/TC 108/SC 5 - Condition monitoring and diagnostics of machines
- International Energy Agency Ocean Energy Systems (IEA OES)
- International Network on Offshore Renewable Energy (INORE)
- International Towing Tank Conference Association (ITTC) Association
Informal liaisons are established with other organizations both within and outside IEC as needed.
Each PT, MT, and AHG is led by a Convener. Conveners are typically appointed by the National Committee that submits a New Work Item Proposal (NWIP) that TC-114 has approved.
TC-114 holds one plenary meeting each year, usually in the Spring, where delegates from every National Committee meet to deliver progress reports, discuss NWIPs, plan for the coming year and develop means to streamline TC-114 standards-development processes.
IEC TC-114 Terminology
Terminology for the IEC standards is defined in the Marine Energy Electropedia . It provides definitions in English and French and translates the term or phrase into 8 other languages. Abbreviations used in IEC documents can be found in the IEC Acronyms chart. Additionally, definitions of terms used in environmental monitoring can be found on the Tethys Glossary and the PRIMRE Glossary.
IEC TC-114 Standards Development
The development of International Standards is an important foundation for trade and innovation and can promote the rapid transfer of technology into new and emerging markets. The suite of International Standards, and Technical Specifications, under development at the IEC combines the best experience of industry, researchers, consumers and regulators with over 20,000 experts from companies, laboratories, academia and government. These documents cover a broad range of topics, including safety, performance, interoperability and the environment and form the basis for global conformity assessment activities. Further, these ongoing efforts are intended to promote safety and consumer confidence while stimulating economic growth and development.
The development of Standards and Technical Specifications is accomplished by nationally nominated subject matter experts working on Project Teams, Working Groups, Ad-hoc Groups, etc. Technical Committee 114 reports to the Standards Management Board (SMB), who is tasked with the management of International Standards development and in turn reports on progress to the IEC Board.
Individual Standards and Technical Specifications begin as New Work Item Proposals, put forward by P-member countries who become the Project Team convener following international approval. Progress continues through various iterations of Committee Draft (CD), with National Committee review and comment on each draft. The draft International Standard, or draft Technical Specification, is formally voted upon and accepted based on specific voting requirements.
Following acceptance, the document generally enters a stability period of three to five years in which ad-Hoc Groups are formed to collect industry feedback and prepare the document for edits following the stability period. After the stability period, a Maintenance Team is usually formed to oversee updates and improvements to the documents, ultimately published in a new edition. In the case of a Technical Specification, the Maintenance Team may lead the transition to an International Standard following the stability period.

American National Standards Institute (ANSI)
“In the United States, the American National Standards Institute (ANSI) oversees standards and conformity assessment activities in the United States.” (link)
“The American National Standards Institute (ANSI) is a private, non-profit organization that administers and coordinates the U.S. voluntary standards and conformity assessment system. Founded in 1918, the Institute works in close collaboration with stakeholders from industry and government to identify and develop standards- and conformance-based solutions to national and global priorities.” (link)
“ANSI is not itself a standards developing organization. Rather, the Institute provides a framework for fair standards development and quality conformity assessment systems and continually works to safeguard their integrity. And as a neutral venue for coordination of standards-based solutions, the Institute brings together private- and public-sector experts and stakeholders to initiate collaborative standardization activities that respond to national priorities.” (link)
“The U.S National Committee (USNC) of the International Electrotechnical Commission (IEC) serves as the focal point for U.S parties who are interested in the development, promulgation, and use of globally relevant standards for the electrotechnical industry. The USNC is also engaged in the assessment of conformance to standards, undertaking work in areas such as testing, certification, and accreditation.” (link)
“The USNC is a totally integrated committee of ANSI. ANSI provides administrative support to the USNC and its more than 4,000 U.S. managerial, engineering, scientific, and professional participants. ANSI also provides the fiduciary framework by which the USNC’s financial obligations are met, including the payment of annual dues to the IEC.” (link)
United States Technical Advisory Group (US TAG)
The United States participates in TC-114 through its U.S. National Committee (USNC) Technical Advisory Group (TAG), or US TAG, which was established and is managed by the American National Standards Institute (ANSI). ANSI also serves as the U.S. liaison to the International Organization for Standardization (ISO) in the development of ISO standards and coordinates efforts when IEC and ISO need to form a joint working group to address special issues of common interest.
In response to the IEC’s determination of the need to establish a new Technical Committee (TC) to address the standards requirements of the marine energy industry, in 2008 ANSI formed a Technical Advisory Group (TAG) with a mandate to establish subcommittees, known as “Shadow Committees” (SC), which participate in the standards development process of the various Project Teams and Maintenance Teams as they are formed by TC-114. Currently the US TAG comprises of approximately 100 volunteer members who participate in the various working groups.
Currently, the leadership team of the US TAG is as follows:
Technical Advisor (Head of Delegation to TC-114) – Bill Staby (Bluewater Network, LLC)
Deputy Technical Advisor – Phil Beauchamp
Steering Committee Member – Roger Bagbey (Cardinal Engineering)
Secretary – Arielle Cardinal (NREL)
The US TAG holds one face to face plenary meeting per year at which US TAG leadership meets with the Shadow Committee Chairs to discuss the progress of each Shadow Committee, resolve problems, make forward plans and develop a list of topics that need the attention of TC-114 leadership. Each Shadow Committee sets its own work schedule for reviewing documents and communicating amongst themselves and the working groups in which they are members. In general, only the Shadow Committee Chair and one designated Subject Matter Expert (SME) are allowed to attend face-to-face meetings called by the Convener of a working group. For more details about the various PTs, MTs and AHGs in which the US TAG participates, please refer to the “Standards Development” tab.

National Standard Adoption
In many regions and jurisdictions, it is necessary to reference national standards within laws, codes and regulations. National standards can be identical adoptions of international standards without modification, adoptions of international standards with any necessary national differences, or written from scratch to meet the needs of the marketplace. In the United States, organizations can become ANSI-Accredited Standards Developers (ASDs) and have the authority to publish American National Standards (ANSs).
For the Marine Energy industry in the United States, the American Renewable Energy Standards and Certification Association (ARESCA), a Vermont based 501(c)(6) nonprofit, is an ASD that has been given the authority by the US TAG to IEC TC 114 to adopt international standards published by IEC TC 114 as ANSs. To date, ARESCA has adopted 10 standards published by IEC TC 114 in the US without national difference. These Marine Energy ANSs can be purchased on the ANSI webstore (link below) and are branded as ANSI/ARESCA standards. The Standards Committee of the Board (SCB) manages the national adoption process for ARESCA and the full suite of IEC TC 114 standards, including new standards and new editions of existing standards, will be adopted as ANSs over time.

Other Standards
There are several other standards organizations that develop and publish standards relevant to offshore operations and technology development. For example, the International Organization for Standards (ISO) is an international organization that prepares and publishes voluntary, consensus-based, international standards that support innovation and provide solutions to global challenges. Developed through global consensus, ISO has developed over 24,000 International Standards, all of which are included in the ISO Standards catalogue. The American Petroleum Institute (API) is an industry-specific standards organization focused on offshore petroleum and petrochemical equipment. Many of the API standards have been incorporated into state and federal regulations and adopted by the ISO for worldwide acceptance. The table below outlines relevant offshore industry standards from organizations around the world.
