Manifa field causeway, Saudi Arabia Available to Purchase

This paper reviews the design criteria and design development from option study to detailed design, and construction of an offshore island and causeway development off the Eastern Province of Saudi Arabia. The Manifa project, which is currently under construction, consists of 21 km of main causeways and 21 km of lateral causeways connecting to the 27 drilling and water injection islands and will support oil production of 900 000 barrels/day. The islands are each 9 ha (about the size of 13 football pitches). The works require the dredging and land reclamation of approximately 37 Mm³, and the rock armour revetments are approximately 120 km in extent and require the quarrying and placement of 10 Mt of rock. To fulfil environmental requirements, openings have been introduced to the causeway which are bridged by 4 km of bridges including one of 2·4 km.
