ABSTRACT: Vopak Horizon Fujairah Limited is the biggest oil storage and bunkering company in the Emirate of Fujairah with a sizeable terminal that has recently undergone its fifth expansion. This includes an extension to the existing marine jetty with the provision of two additional berths in 15m water depth for vessels with a capacity up to 110,000 DWT. The jetty structures are founded on tubular steel piles driven into shallow variably cemented very weak to weak sedimentary rocks with varying calcium carbonate content. A static uplift load test to failure followed by a static compression load and numerous dynamic End of Initial Drives (EoID) and restrike tests with signal matching were carried out for a better understanding of the pile behaviour. This paper describes the pile tests conducted, results obtained and their interpretations. The suitability of the API RP2A method for clays in estimating capacity of piles driven into the calcarenite at this site is investigated. The pile response from the static load test due to reversals in loading directions is also discussed.
