Expanding coastal cities – Proof of feasibility for modular floating structures (MFS)

Land scarcity in and around coastal cities is a growing problem in both industrialized and developing nations. The lack of development areas increases the tension between infrastructure needs, urban needs and nature – impacting both growth and quality of life. This study advocates that floating structures can offer a unique avenue to explore new and sustainable ways of addressing these issues. Recognizing that no comprehensive analysis or study on the legal requirements needed for the realization of such projects has yet been conducted, the study's first aim is to define the required design guidelines by synthesizing statutory requirements, building codes and international regulations. From a statutory perspective, these encompass two disciplines: civil engineering and naval architecture. To this end, a preliminary design of a Modular Floating Structures (MFS) module is presented, reconciling the design requirements of the two disciplines, in order to proof the feasibility of the MFS technology for urban use offshore. The study mainly focuses on structural and safety aspects, and sheds light on other crucial factors for offshore dwelling feasibility, such as occupant comfort.
