The Melville Island Bulk Fuel Facility is located in the Eastern Timor Sea, off the coast of the Northern Territory and is part of the Tiwi Islands. The location for the new marine facility is at the northern end of the Apsley Strait and the end of the Arrimu Creek. The Port currently is predominantly used for forestry and agriculture.
The Head client, Ezion Holdings Ltd provides offshore marine logistics and support services to the offshore oil and gas industries. This expansion is to meet the fuel storage and distribution requirements of the oil and gas multinationals that are operating in the Northern Territory of Australia and the Timor Sea.
PDC’s scope included the structural design and detailing services of three identical 100ML bulk storage tanks, 30m in diameter and 15.2m high with a central column support. The battery limits were the underside of the tank to the nozzle flanges and appendages.
PDC also designed and detailed the transport cradles required to enable the rolled plates for the Melville Tank Walls to be transported from Perth, Western Australia to Site.
Due to the compressed schedule, plates for the roof and walls were selected in the first week to enable materials to be ordered to suit the construction schedule.
PDC also carried out early option studies to ensure that the site construction time was minimised via the selection of materials for the roof. PDC also designed the structural system to suit the transportation limits from Perth to Site.
As the shop detailing was part of the scope it enabled this to commence to completion of the detail design. By doing the detailing in-house it provided seamless coordination and communication between the engineering and detailing teams.
