Project

Jurong Island is a 3,200 ha man-made island formed by joining several small islands through land reclamation. Hin Leong Trading, Singapore is building an oil storage terminal called Universal Terminal, at Banyan Logispark on Jurong Island. The Universal Terminal, one of the world’s largest and Asia’s biggest independent oil storage facility, consists of 73 tanks, ranging in diameter from 13.6m to 78.6m and in height from 15m to 22.3m. The 73 tanks are divided into 12 tank farms. It also includes valve manifolds, pump stations and other facilities.

The soil on site is made up of 20m to 35m of loose to medium dense reclaimed sand fill underlain by stiff Jurong Formation. The compaction works were designed and built by Keller to ensure that settlements were within allowable limits with adequate bearing capacity for stability. Vibro Compaction was executed using both single and twin vibro compaction rigs.

Vibro Compaction works of approximately 200,000m2 area of sand, which includes areas to be used for construction of tanks, manifolds and pump stations, was completed within a short span of 6 months between December 2005 and May 2006 using three twin vibro rigs and two single vibro rigs.
