Modular multi-purpose floating structures (MMFS) are an innovative approach for space creation on the sea. The basic idea is connecting a number of standardised modular units to form a “land on sea” of the desired size and shape for generic applications. This research was part of the multi-purpose floating structure (MPFS) project funded by the Land and Liveability National Innovation Challenge (L2 NIC) Directorate and JTC Corporation in Singapore. This paper presents an overview of the concept development and evaluation of the modular units and inter-modular connectors. Results from detailed structural and hydrodynamic analyses as well as scaled model tests show that the proposed solution is technically feasible. The construction methodology and preliminary cost estimate are also presented and discussed.
