Butting signs its largest order The Ichthys gas-condensate field, where pipe-laying operations are due to begin in 2013, lies off the Kimberley Coast of Western Australia. Butting is playing a significant role in constructing the 889km long pipeline that will run from the offshore production platform to Darwin, where the gas is to be processed. The company is supplying about 75km of Butting bimetal (BuBi ® ) pipes. The contract for the Ichthys LNG project was signed with INPEX at the beginning of this year. The pipes ordered for the Ichthys LNG project are made frommaterial grades TP 317L/UNS S31703 for the inner pipe, and SAWL 450 FD for the carbon steel outer pipe. Construction is being performed according to the DNV-OS-F101 standard and to other requirements of the customer specifications. The size for this order is 457 x (21.9+3) mm. The BuBi pipes consist of an inner pipe and an outer carbon steel pipe. The two pipes are connected to each other with

hydraulic expansion to a mechanical tight fit. The process developed by Butting for mechanically connecting two pipes is cheaper than a solid-wall version. The company states that the BuBi pipe ensures all of the properties of metallurgically clad pipes. The process also permits a wide selection of material combinations.
