The requirements of this document may be modified as long as it can be reasonably demonstrated that the security of the system is not affected. Compliance with this document is accompanied by Comply with other applicable local regulations. Design requirements for marine energy systems1 ScopeThis document specifies the requirements for the system design of wave energy, tidal energy and other current energy conversion devices (collectively referred to as ocean energy conversion devices) to ensure its engineering integrity. Its purpose is to provide an appropriate level of protection against a variety of structural, mechanical, Damage caused by all dangers of serious failure of electrical or control systems. Figure 1 illustrates the scope of application of this document and the Key interfaces to other elements. Figure 1 Boundaries and interfaces of ocean energy conversion device systems This document specifies the design requirements for the main structure, ancillary equipment, subsea connections, mechanical systems and electrical systems of ocean energy conversion devices to To ensure the survivability of this unit under specific site environmental conditions. This document applies to floating, fixed or shore unattended during operation Base type ocean energy conversion device. Note. Mooring design guidelines for floating ocean energy conversion devices, see IEC TS62600-10. In addition to environmental conditions, this document also describes design conditions (operation, operation with faults, shutdown, etc.), design type (normal conditions, extreme conditions, etc.) conditions, abnormal conditions, and transport conditions) and limit states determined using limit state design methods (operational limit states, extreme limit states ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 41088-2021_English be delivered?Answer: Upon your order, we will start to translate GB/T 41088-2021_English as soon as possible, and keep you informed of the progress.
