Introduction

As a marine energy conversion device widely used in public utilities and social power supply, the mooring system is an important prerequisite for its safe and reliable operation.

This document is based on the above requirements and provides developers, manufacturers and users with Ocean energy - Guidance on the evaluation of mooring systems for wave energy, tidal energy and other water flow energy conversion devices.

Conceptually, many ocean energy conversion devices, with the exception of wave energy converters, work similarly to wind turbines.

There are few standards or technical specifications for the evaluation of mooring systems for energy conversion devices (including wave energy, tidal energy and other water flow energy).

The two sides are working together to develop detailed standards to address this issue.

In the structural design process of ocean energy conversion devices, it is extremely important to evaluate the performance of the mooring system itself and the coupling effect between it and the device.

During the design phase, the performance of the mooring system should be evaluated using relevant standards.

This document aims to.

--- Issues and reference indicators for the evaluation of mooring systems for wave energy, tidal energy and other water flow energy conversion devices;

---Establish assessment methods and application technical guidelines.

---Develop assessment procedures related to the design, installation and maintenance of mooring systems for ocean energy conversion devices.
