Abstract
Hydrocarbon is a major source of energy for sustainable development. Storage of hydrocarbon products, however, requires a significant amount of land space to land-scarce countries like Singapore. This paper presents an alternative way of storing hydrocarbon in Singapore coastal waters through the innovative design of a floating hydrocarbon storage facility. The design comprises free-floating and self-stabilizing tanks enclosed by barges that form a floating hydrocarbon storage facility. The tanks are made of prestressed concrete and they are designed to be self-stabilized when floating in the sea water. Owing to the lack of available design guidelines, design requirements on the stability and motion criteria for floating storage tanks are developed based on a review of existing codes of practice and design specifications for both onshore tanks and offshore vessels. A comprehensive study on the hydrostatic performance of various proposed floating tank design concepts with different storage capacities is carried out. This paper aims to give design recommendations on the tank’s storage capacity and dimensional aspect ratios that fulfill the recommended stability requirements and motion criteria.

Summary
Singapore relies heavily on the import of fuels to ensure a secure, reliable, and diversified supply of competitively-priced energy. Petroleum products and crude oil occupied 94% of the total imported energy in 2015. A vast amount of space is required to store and trade hydrocarbon products. In land-scarce countries like Singapore, there is a need to create additional space through innovative engineering solutions. Singapore created an artificial island, called Jurong Island, in 2009 by amalgaming seven offshore islands through land reclamation to grow the petrochemical industry. In 2014, the Jurong Rock Caverns, excavated at some 120 m beneath the ground and was put into operational use for massive oil storage. These approaches of creating space have their own limitations
