Reducing Hydroelastic Response of Very Large Floating Structure: A Literature Review

Abstract

Floating structure is applied as floating wave breaker, floating airport and etc. Applications of these structures rise because of being environmental friendly and fast construction. To design floating structure first step is hydrodynamic analysis under wave effect. As the depth of structure is too smaller than the other dimensions, this structure behaves elastically. Hydroelastic analysis is used to obtain its deformation under wave action. Reduction of the hydroelastic responses may increase serviceability and safety. There are many ways to reduce the hydroelastic response of VLFS. This paper was considered the analysis and hydroelastic reduction of VLFS.

Penataan Gedung Serbaguna sebagai Bagian Ruang Publik Melalui Konsep Arsitektur Analogi (Studi Kasus: Kampung Tua Tiangwangkang, Batam, Indonesia)

“…Struktur yang digunakan untuk mampu mengapung di atas laut sekaligus menahan beban-beban di atasnya disebut VLFS (Very Large Floating Structure). Terdapat 2 tipe VLFS yang sudah digunakan hingga kini, yaitu struktur pontoon dan struktur semisubmersible [23]. Wang dan Tay [24] menjelaskan bahwa tipe struktur pontoon lebih dianjurkan untuk ditempatkan sebagai pelabuhan atau wilayah yang dekat dengan bibir pantai, sedangkan tipe struktur semisubmersible digunakan di wilayah laut lepas (jauh dari daratan) dikarenakan struktur yang masif untuk menahan dorongan gelombang air laut yang kuat.…”

Optimization Analysis of the Shape and Position of a Submerged Breakwater for Improving Floating Body Stability

“…

With the increasing demand for industrial and residential land, studies have been conducted on the construction of very large floating structures, such as floating airports, floating bridges, and multipurpose marine spaces, by installing floating structures in coastal and offshore areas (Watanabe et al, 2004;Lamas-Pardo et al, 2015). The first step in the design of such floating structures is to conduct a hydrodynamic analysis considering wave loads (Tavana and Khanjani, 2013). To reduce the hydroelastic responses of floating structures, various methods have been presented, including submerged breakwaters, floating breakwaters, and oscillating water column chambers.
