Special Issue Information

Dear Colleagues,

Various types of offshore installations are needed in coastal areas and ocean zones. Traditionally, offshore structures have been mainly constructed for the offshore oil and gas industries. To tackle climate change and to meet energy demands, innovative offshore installations can be considered, such as floating renewable energy facilities and floating transportation infrastructures. Among the floating renewable energy facilities, many wave energy converter (WEC) technologies are still at a pre-commercial stage, and significant research and development are required to improve their competitiveness. For example, the integration of WECs in multifunctional offshore structures can be an interesting alternative. On one hand, WECs can supply power to integrated structures, e.g., aquaculture platforms, wind turbine platforms, oil and gas platforms, or modular floating structures. On the other hand, WECs can serve as a floating wave-breaker to reduce wave loads acting on integrated structures.

The aim of this Special Issue on “Offshore Installations and Wave Power Generation” is to publish high-quality papers, which offer original ideas and new methodologies, with a clear indication of the innovations with respect to existing solutions. Topics addressed in this Special Issue may include but are not limited to:

  • Innovative offshore installations;
  • Numerical analysis of offshore installations;
  • Experimental techniques for offshore installations;
  • Inspection, repair, and maintenance of offshore structures;
  • Modular floating structures;
  • Full-field offshore experience and real data of offshore installations;
  • Design and analysis of wave energy converters;
  • Wave energy converters combined with offshore wind turbines;
  • Integration of wave energy converters into multifunctional offshore structures;
  • Optimization of wave energy converters;
  • Marine renewable energy installations.

In this Special Issue, we welcome all related research. Contributions to this collection will significantly enhance the development of offshore installations and wave power generation, helping to accomplish their commercialization.

Aiming at the problem of excessive vertical vibration caused by seismic primary waves in jacket structures located in seismic zones in China, a new type of shear plate metal damper with upper and lower elliptical openings (SPA) is proposed in this paper. The seismic model test is carried out to compare the shear plate metal damper with three traditional opening forms, central elliptical opening, single row opening, and double row opening, and the hysteretic curve, skeleton curve, and cyclic hysteretic energy dissipation capacity are analyzed. The results show that the energy dissipation performance of the new shear plate metal damper with upper and lower elliptical openings proposed in this paper is better than that of the other three types of dampers.

The uniformity of the wake on the submarine propeller disk is the key factor affecting the vibration and noise performance of the propeller. To study the influence of the fillets on the uniformity of submarine wake field and propeller unsteady bearing force, the submarine resistance calculation and self-propulsion calculation were carried out using the Detached-Eddy Simulation (DES) method. The characteristics of the wake field and hydrodynamic performance of the original and improved plan were compared and analyzed in detail. The fillets improve the wake distribution at the propeller disk by reducing the horseshoe vortex, and the fillets mainly affect the flow field characteristics of the inner radius area. The fillets can effectively reduce the axial velocity pulsation and improve the quality of the wake field. The frequency–domain curve shows that the bearing force and torque pulsation value of the improved plan are smaller than that in the original one, indicating that the fillets are conducive to controlling the vibration and noise performance of the submarine propeller. The results show that the fillets can effectively improve the flow field quality in the wake fields and reduce the propeller unsteady bearing force. Full article
