This document provides design requirements to ensure the engineering integrity of wave, ocean, tidal and river current energy converters, collectively referred to as marine energy converters. Its purpose is to provide an appropriate level of protection against damage from all hazards that may lead to catastrophic failure of the MEC structural, mechanical, electrical or control systems. Figure 1 illustrates the scope of this document and critical interfaces with other elements of a marine energy converter installation.

This document provides requirements for MEC main structure, appendages, seabed interface, mechanical systems and electrical systems as they pertain to the viability of the device under site-specific environmental conditions. This document applies to MECs that are either floating or fixed to the seafloor or shore and are unmanned during operational periods

NOTE Refer to IEC 62600-10 for guidance on the design of moorings for floating MECs.

In addition to environmental conditions, this document addresses design conditions (normal operation, operation with fault, parked, etc.); design categories (normal, extreme, abnormal and transport); and limit states (serviceability, ultimate, fatigue and accidental) using a limit state design methodology

Several different parties may be responsible for undertaking the various elements of the design, manufacture, assembly, installation, erection, commissioning, operation, maintenance and decommissioning of a marine energy converter and for ensuring that the requirements of this document are met. The division of responsibility between these parties is outside the scope of this document

This document is used in conjunction with IEC and ISO standards cited as normative references, as well as regional regulations that have jurisdiction over the installation site.

This document is applicable to MEC systems designed to operate from ocean, tidal and river current energy sources, but not systems associated with hydroelectric impoundments or barrages. This document is also applicable to wave energy converters. It is not applicable to ocean thermal energy conversion (OTEC) systems or salinity gradient systems.

Although important to the overall objectives of the IEC 62600 series, this document does not address all aspects of the engineering process that are taken into account during the full system design of MECs. Specifically, this document does not address energy production, performance efficiency, environmental impacts, electric generation and transmission, ergonomics, or power quality.

This document takes precedence over existing applicable standards referred to for additional guidance. This document adheres to a limit state design approach utilizing partial safety factors for loads and materials to ensure MEC reliability in accordance with ISO 2394. 

MECs designed to convert hydrokinetic energy from hydrodynamic forces into forms of usable energy, such as electrical, hydraulic, or pneumatic may be different from other types of marine systems. Many MECs are designed to operate in resonance or conditions close to resonance. Furthermore, MECs are hybrids between machines and marine structures. The control forces imposed by the power take-off (PTO) and possible forces from faults in the operation of the PTO distinguish MECs from other marine structures.

The document is applicable to MECs at the preliminary design stage to those that have progressed to advanced prototypes and commercial deployment. It is anticipated that this document will be used in certification schemes for design conformity.

The purpose of this document is to provide uniform methodologies for the design and assessment of mooring systems for floating Marine Energy Converters (MECs) (as defined in the TC 114 scope). It is intended to be applied at various stages, from mooring system assessment to design, installation and maintenance of floating Marine Energy Converters plants. 

This document is applicable to mooring systems for floating Marine Energy Converters units of any size or type in any open water conditions. Some aspects of the mooring system design process are more detailed in existing and well-established mooring standards. The intent of this document is to highlight the different requirements of Marine Energy Converters and not duplicate existing standards or processes. 

While requirements for anchor holding capacity are indicated, detailed geotechnical analysis and design of anchors are beyond the scope of this document.

This part of IEC 61400 specifies additional requirements for assessment of the external conditions at an offshore wind turbine site and specifies essential design requirements to ensure the engineering integrity of fixed offshore wind turbines. Its purpose is to provide an appropriate level of protection against damage from all hazards during the planned lifetime.

This document focuses on the engineering integrity of the structural components of an offshore wind turbine but is also concerned with subsystems such as control and protection mechanisms, internal electrical systems and mechanical systems. A wind turbine shall be considered as a fixed offshore wind turbine if the support structure is subject to hydrodynamic loading and it is founded on the seabed. The design requirements specified in this document are not sufficient to ensure the engineering integrity of floating offshore wind turbines. For floating installations, reference is made to IEC 61400-3-2. In the remainder of this document, the term “offshore wind turbine” is assumed to refer to those that are fixed to the seabed. This document should be used together with the appropriate IEC and ISO standards mentioned in Clause 2. In particular, this document is fully consistent with the requirements of IEC 61400-1. The safety level of the offshore wind turbine designed according to this document shall be at or exceed the level inherent in IEC 61400-1. In some clauses, where a comprehensive statement of requirements aids clarity, replication of text from IEC 61400-1 is included.

1.1 General

This Standard provides requirements and guidance for a consistent approach on how to plan and conduct a study to evaluate different HCF design features while ensuring that the resources required and level of rigour match the undertaking.

Note: The focus of these studies should be aligned with the objectives of the funding agency or study sponsor to address HCF planning or design issues or to learn from elements of the completed projects to inform future projects. The study can include planning, design, and construction (PDC) studies and post-occupancy evaluations (POE).

1.2 Application

This Standard applies to HCF projects, including new construction or redevelopments of existing facilities (e.g., additions, renovations), and is intended to be used by HCFs providing services regardless of type, level of care, size, or location.

1.3 Inclusions

This Standard is developed for a broad range of users, including, but not limited to, HCFs, funding agencies, governments, professional designers and planners, architects, engineers, infection prevention and control professionals, health care teams and clinical staff, vendors, researchers, and internal and external evaluators.

This Standard supports interdisciplinary design teams (IDT) for an HCF project as defined in CSA Z8000 that includes key members of the HCF as subject matter experts: administrators, health care program and clinical planners, clinical staff, infection prevention and control professionals, facility operations and maintenance staff, patients and their families, and non-clinical support staff. Other key members of the IDT may include non-HCF individuals (e.g., professional designers, vendors, funding agencies).

1.4 Climate change mitigation and adaptation

This standard incorporates studies which assess the effectiveness, efficacy, and implementation of climate change mitigation and adaptation.

1.5  Clinical practice and operations

Draft amendment to C22.1

Draft amendment to C22.1

1.1 General

This Standard provides a framework for the requirements and guidance for a consistent approach on how to plan and conduct functional suitability and technical performance assessments of existing HCFs/NHFs, to determine their ability the support current and future health care service delivery.

1.1.1 Categories of assessments

There are two categories of assessments: Functional Suitability Assessments (see Clauses 4.4.1 and 6) and Technical Performance Assessments (See Clauses 4.4.2 and 7).

1.1.2 Types of assessments

In each of the two categories of assessments, there are three types of assessments to create a tiered approach which may be tailored to the purpose of the assessment: Current State, Gap Analysis and Future State Options (See Clauses 3.1, 4.5, 6.2 and 6.3.3).

These types are typically progressive, although not necessarily mutually exclusive:  a Gap Analysis will require that a Current State is completed prior to or as a part of the Gap Analysis. Future State Options will require some elements of Current State and Gap Analysis information to be available. See Figure 1.

1.2 Application

This Standard applies to HCFs, including existing hospitals, LTCH, outpatient HCFs, and NHF or settings being considered for use in the delivery of health care services. 

It is intended to be used by HCFs providing services regardless of type, level of care, size, or location.

Where applicable by AHJs, the focus of the assessment should be aligned with the objectives of the funding agency or study sponsor to address HCF planning or design issues, to inform capital planning and investment, or to learn from elements of the completed assessments to inform future studies and/or projects.

Future studies can include planning, design, and construction (PDC) studies and post-occupancy evaluations (POE) and Sustainability or Climate Resilience Plans (See CSA Z8003 for more information on PDC and POE).

1.3  Inclusions, users and interdisciplinary teams (IDT)

This Standard is developed for a broad range of users, including, but not limited to, HCFs, funding agencies, governments, professional design and planning teams, architects, engineers, infection prevention and control professionals (IPC), health care teams, providers and clinical staff, vendors, researchers, and internal and external evaluators.

This Standard supports IDT involvement in the assessments, in order to determine the scope of the assessment and to guide an assessment of the functional suitability and the technical performance of the building systems.

As applicable, input from health care authorities may also be necessary to establish the assessment purpose and scope.

Note: The IDT members of the HCF become the subject matter experts (SME) for the assessments and include administrators, health care program and clinical planners, clinical staff, infection prevention and control professionals, facility operations and maintenance staff, patients and their families, and non-clinical support staff. Other key members of the IDT may include non-HCF individuals (e.g., professional design and planning teams, vendors, funding agencies).

 

1.1 Facilities

1.1.1 Types of facilities

This Standard addresses the design and operation of EMPs for nuclear facilities as described in Clause 1.2 of CSA N288.0.

1.1.2 Facility lifecycle

The nature and extent of environmental monitoring requirements will change during the lifecycle of the facility. This Standard addresses monitoring performed during

a) site preparation, construction, and commissioning;

b) operations;

c) decommissioning; and

d) any period of institutional control that might follow closure of the facility.

Notes:

1) In Canada, baseline monitoring prior to the submission of an application for a licence to prepare a site might not be fully addressed by this Standard. For more information on pre-licensing baseline monitoring, see CNSC REGDOC-1.1.1, Section 3.4, Appendix B.3, and Appendix C, CNSC REGDOC-2.9.1, and BCMOE, 2016.

2) Data from baseline monitoring are generally used as an input into the ERA. Many of the recommendations and considerations provided within this Standard are applicable to environmental baseline activities. In addition, pre-licensing baseline data collection ideally places special emphasis on environmental factors and elements that might be carried forward to the EMP.

1.2 Operating conditions

1.2.1 Monitoring during normal operations

The monitoring described in this Standard is applicable where human and/or non-human biota might routinely be exposed to

a) low-level effluents and emissions of nuclear and hazardous substances released to the environment as the result of the normal operation of a nuclear facility; or

b) physical stressors imposed on the environment as the result of the normal operation of a nuclear facility.

1.2.2 Monitoring during accidental releases

This Standard does not address acute or high-level exposures that can result from accident scenarios (e.g., design basis accidents, beyond design basis accidents), although some parts of this Standard might be applicable to the monitoring of the long-term effect of such an event. In these cases, the operator of the facility is responsible for determining the applicability of the guidance.

1.2.3 Monitoring program boundary

This Standard addresses monitoring conducted in the environment within the spatial boundaries defined in the ERA. This monitoring starts beyond

a) the final point of control for an airborne or waterborne release; or

b) the facility boundary.

Note: The facility boundary may be the outer wall or foundation of the building housing the licensed activity. In Canada, the facility boundary may be the boundary of the protected area as defined in Section 9 of the Nuclear Security Regulations for nuclear facilities to which those Regulations apply.

Monitoring extends out to locations determined in the ERA by receptors and receptor range. The spatial boundaries might be different for each media.

Notes:

1) This Standard does not address effluent and emissions monitoring, which involves the monitoring of the release of nuclear and hazardous substances to the environment. See CSA N288.5 for additional information on effluent and emissions monitoring programs.

2) This Standard assumes that the exposure to nuclear or hazardous substances by persons working or visiting inside the facility boundary will be controlled through the facility radiation protection program, environmental protection program, or health and safety program.

1.3 Contaminants and physical stressors

This Standard provides guidance on monitoring for the contaminants and physical stressors in environmental media, as identified in the ERA and/or determined by the AHJ. These contaminants and physical stressors can include one or more of the following:

a) hazardous substances such as toxic, corrosive, or environmentally deleterious substances;

b) nuclear substances and radiation; and

c) physical stressors.

1.4 Receptors and biological effects

This Standard provides guidance on designing an EMP that can

a) provide the data necessary to assess potential biological effects on receptors; and

b) measure direct biological effects on receptors.

Notes:

1) Receptors are as identified in the ERA and/or as determined by the AHJ. The receptors can include human or non-human biota.

2) Measurements of effects in non-human biota (measurement endpoints) can occur at the level of an individual organism, a population, or a community. Often measurement endpoints at the individual level are intended to represent the potential for higher level effects (assessment endpoints) that are of primary concern to environment managers.

1.5 Interpretation of data

This Standard provides guidance on the interpretation of data collected by an EMP. However, users are cautioned that AHJs can impose requirements regarding data analysis and interpretation that differ from those described in this Standard. The operator of the nuclear facility is responsible for determining what data analysis and interpretation are necessary to ensure compliance with AHJ requirements.

1.6 Dose assessment

Although one of the objectives of an EMP may be to provide the data required to support radiation dose assessments or assessments of exposure to hazardous substances, this document does not address dose assessment methods for either human or non-human biota.

Note: Assessments of dose/exposure are normally part of the ERA and any subsequent assessments based on environmental monitoring data are ideally done the same way, using CSA N288.6 or equivalent standards and guidance that were used in the ERA or their most recent updates. Monitoring to support dose assessment is further addressed in Clause 7.4.

1.7 Reporting

Reporting requirements are outlined in Clause 8 of CSA N288.0. However, users are cautioned that AHJs may impose reporting requirements that differ from those described in this Standard and CSA N288.0. The operator of the nuclear facility is responsible for determining the required frequency and content of reports to AHJs necessary to ensure compliance.

1.8 Terminology

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5     Interprétation des données

Cette norme énonce des lignes directrices visant l’interprétation des données recueillies dans le cadre d’un PSE. Cependant, les utilisateurs sont avisés que l’autorité compétente est susceptible d’imposer des exigences concernant l’analyse et l’interprétation des données qui diffèrent de celles prescrites dans cette norme. C’est à l’exploitant de l’installation nucléaire qu’il incombe de déterminer quelles analyses et interprétations des données sont nécessaires pour assurer la conformité aux exigences de l’autorité compétente.

 

1.6     Évaluation de la dose

Bien qu’un des objectifs d’un PSE peut être de fournir les données nécessaires à l’évaluation de la dose de rayonnement ou à l’évaluation de l’exposition à des substances dangereuses, le présent document ne traite pas des méthodes d’évaluation de la dose pour le biote humain ou non humain.

Note : L’évaluation de la dose/exposition fait normalement partie de l’ÉRE, et toute évaluation subséquente basée sur les données de surveillance environnementale est idéalement effectuée de la même manière, en se basant sur CSA N288.6 ou sur les mêmes normes et lignes directrices que celles utilisées dans l’ÉRE ou les éditions les plus récentes de ces documents. Voir l’article 7.4 pour obtenir d’autres renseignements sur la surveillance à l’appui de l’évaluation de la dose.

 

1.7     Établissement de rapport

Les exigences sur la consignation des résultats sont énoncées à l’article 8 de

CSA N288.0. Cependant, les utilisateurs sont avisés que l’autorité compétente peut imposer des exigences en matière d’établissement de rapport qui diffèrent de celles prescrites dans cette norme et dans CSA N288.0. C’est à l’exploitant de l’installation nucléaire qu’il incombe de déterminer la fréquence et la teneur des rapports présentés à l’autorité compétente pour assurer sa conformité.

 

1.8     Terminologie

Dans cette norme, le terme « doit » indique une exigence, c’est-à-dire une prescription que l’utilisateur doit respecter pour assurer la conformité à la norme; « devrait » indique une recommandation ou ce qu’il est conseillé mais non obligatoire de faire; et « peut » indique une possibilité ou ce qu’il est permis de faire.
