Non-helical umbilical Deep Down, Inc, an oilfield services company specialising in complex deepwater and ultra-deepwater oil production distribution system support services, has completed its first steel tube umbilical for a major oil and gas operator in the Gulf of Mexico.

installation support and engineering services, umbilical terminations, loose- tube steel flying leads, installation buoyancy, ROVs and tooling, marine vessel automation, control, and ballast systems. The company supports subsea engineering, installation, commissioning and maintenance projects through specialised, highly experienced service teams and engineered technological solutions. Its primary focus is on more complex deepwater and ultra-deepwater oil production distribution system support services and technologies, used between the platform and the wellhead.

Deep Down in the steel tube umbilical market,” commented CEO Ron Smith. “We are able to offer our customers a steel infield umbilical in any standard configuration of electrical, optical or hydraulic up to 10 miles long, fabricated anywhere in the world more economically and in less time than traditional manufacturing techniques. The demand for steel tube umbilicals in 2013 remains strong and is projected to surpass 2012’s annual sales of $350mn. The ability for us to combine this product with our existing products and services provides our customers with additional options when planning their subsea infrastructure.”

The umbilical, which is based on Deep Down’s patented non-helical design, was tested and manufactured at Deep Down’s Channelview, Texas, USA, facility, and was scheduled for deployment offshore by Deep Down’s installation team during the second quarter of 2013. and manufacturing of our first non-helical umbilical (NHU ® ) is a major step for “The successful testing

actual dimensions and notifies these to the customer before dispatching the goods. As the plant is to be converted during on-going operations, space on the building site is as tight as the time schedule for the construction work. 80 per cent of the welding seams are produced in-house at Butting. This shop welding and the pickling of whole components ensure the required level of quality of seams and surface. Non- destructive tests are carried out on Butting’s premises, so pressure tests and FE or X-ray testing are not required at the construction site. The shaped parts and pipes are called off in accordance with progress and demand on-site. This just-in-time delivery allows Butting to ensure clear operational planning to meet the customer’s requirements. After conversion, the plant will produce 12,000m 3 of drinking water per hour, from the salt water of the Mediterranean. H Butting GmbH & Co KG – Germany info@butting.de www.butting.de

quantity later on, the customer decided on using the material UNS S32750 with wall thicknesses of up to 17.48mm. The shaped parts are used, among other things, as pipe manifolds in the desalinisation process of the plant and must therefore be able to withstand high pressure. High demands are made on dimensional accuracy to ensure that the materials arrive on-site ready for installation, with an absolutely precise fit. Butting therefore documents all

Butting is to undertake the extension of a seawater desalinisation plant in Israel. The plant’s capacities are to be doubled without interrupting operations – a challenge both for the operator and for Butting. The scope of delivery includes a large number of shaped parts in sizes ranging from ½" to 24" and pipes with an outside diameter of 10" or more, with a total tonnage of 162t. Based on the design of the plant and the run-through
