requirements will be met by the use of super duplex material (UNS S32750). The wall thicknesses of the pipes range from 3.76 to 35.6mm, and the total delivery runs to around 1,400 tons. The pipes were manufactured by Butting in 12m lengths and without circumferential weld, in its expanded manufacturing facilities. With the optimised production flow, the welded pipes do not need to leave the production hall from the point when they are shaped from 12m plates and worked into open-seam tubes to their final quality assurance inspection. This cost-effective method benefited Petrofac by enabling their requirements to bemet while saving on circumferential welds on site. Butting has to comply with a tight timetable: the investors have announced that the expanded plant will be completed some time in 2010. By producing and delivering the pipes between September 2009 and April 2010, Butting will help to achieve this ambitious goal. H Butting GmbH & Co KG – Germany info@butting.de www.butting.de

The United Arab Emirates is among the countries with the most extensive oil and gas reserves in the world. However, these resources are not evenly distributed among the seven Emirates: Abu Dhabi, by far the largest in area, has over 90% of the total oil and gas reserves of the UAE. Some 220km to the south of the city of Abu Dhabi is the Asab gas field, currently the site of one of the largest upstream projects in the Middle East. In connection with work by the oil company ADCO to expand the existing facilities and increase capacity, two EPC (engineering, procurement and construction) contracts have been awarded. ADCO is a joint venture of the Abu Dhabi National Oil Company (ADNOC), Shell, Total, ExxonMobil, BP and Partex.

and enhancing the existing gas production centres and oil and gas cleaning facilities. Package B covers the exploitation of the neighbouring Sahil and Shah fields by establishing degassing stations, and laying plant and flowline pipes and the main oil pipelines connecting both Sahil and Shah to Asab. The $2.3bn Package A was awarded in 2009 to Petrofac, an international provider of plant solutions for the oil and gas exploration and production industry. German manufacturer H Butting GmbH & Co KG received an order from Petrofac for the production and delivery of stainless steel pipes in dimensions from 6" to 48", with the bulk of them being 30" x 35.6mm. The pipes are used as transport lines for the aggressive sour gas in various areas of the expanded plant. The resulting corrosion resistance
