| The water depth near the coast of China is relatively shallow and typhoons frequently occur. The design of mooring system for
large wave energy installations against extreme sea conditions has become a technical difficulty restricting the industrialization develop
ment of wave energy installations. Wave energy power generation can provide green energy support for Marine economy and is of great
significance for the development of Marine strategy. Aiming at the system design problem of an improved MW wave energy device against
extreme sea conditions, this paper studies the hydrodynamics characteristics of the platform under different water depths, and compares
the mooring system design scheme using mooring line material with super-elastic and high-strength materials with that of pure anchor chain
catenary mooring system. The mooring load and drift motion characteristics of the platform under extreme sea conditions are studied. The
results show that for shallow water mooring design, the mooring system with elastic cable material can effectively reduce the mooring
load, and can continue to reduce the peak value of mooring load with the increase of the use of elastic cable. However, as the use of elastic
cable reaches a certain value, the continuous increase of elastic cable will limit the effect of reducing the peak value of mooring load.
This study provides valuable insights for the design of shallow-water anti-typhoon mooring systems and the economic assessment of elastic
cable utilization. |
