Deepwater pipeline solutions As global demand for key energy sources increases and the search for hydrocarbons takes the industry into deeper and more difficult environments, Tata Steel products will continue to play a part in their extraction and distribution offshore, meeting demanding offshore line pipe requirements. The company has an extensive track record in every stage of hydrocarbon recovery, from exploration and drilling, oil and gas production and transportation through to refining, processing and developing renewable technologies. than 110,000 metric tonnes, which was manufactured at the company’s 42" mill in Hartlepool, UK. The pipe was laid at water depths of up to 2,250m (7,380ft) and is designed to meet the required specification for deepwater conditions. Richard Broughton, commercial manager for pipelines and petrochemical at Tata Steel, said, “Tata Steel applies decades of experience and expert knowledge to deliver strong, reliable and innovative pipeline solutions for challenging and complex projects around the world. Recent contracts have been awarded based on our excellent dimensional tolerance control, enabling us to offer enhanced deepwater anti-collapse properties, easy fit-up and fast lay rates.”

The company recently completed a £100mn project to provide pipe for the Discovery Producer Services LLC gas pipeline in Keathley Canyon, Gulf of Mexico. Discovery is a 60:40 joint venture between Williams Partners LP and DCP Midstream Partners LP. Tata Steel supplied Discovery’s Keathley Canyon Connector TM with 214 miles (345km) of 20" diameter submerged arc welded line pipe, weighing more

Laying of pipe from Tata Steel

Tata Steel’s pipeline packages include double submerged arc welded (DSAW) line pipe, manufactured at the Hartlepool mill, which is equipped with what is claimed to be the strongest edge crimping and ‘O’ press combination in the world. This enables the manufacture of thicker wall DSAW pipes even in smaller diameters, suitable for withstanding the extreme collapse pressures in the deepest waters. The company’s capability in thick-walled pipe, combined with its tight tolerances, means its line pipe offers further advantages during pipe lay. Magma Global has announced that a major offshore drilling contractor has placed an order for m-pipe ® boost lines for deployment in Q4 2013 on a deepwater drilling riser, as part of a qualification test to determine the suitability of m-pipe for use as riser auxiliary lines. The use of m-pipe for drilling riser auxiliary lines is expected to deliver significant benefits in terms of weight reduction and corrosion resistance. “We are delighted with this first application of m-pipe in a drilling riser configuration and believe m-pipe can deliver significant benefits for deepwater and HPHT drilling projects,”

Tata Steel produces high frequency induction (HFI) welded pipe for reel lay projects, and also manufactures and project manages pipe-in-pipe solutions for high pressure, high temperature (HPHT) pipelines and risers, spools and bends. A comprehensive range of insulation options enables the company to supply the optimum thermal efficiency.

said Steve Hatton, Magma Global’s commercial director.

Magma designed m-pipe for riser, jumper, spool and flowline applications, and the particular challenges found in deep water and high pressure, high temperature and sour service operating environments. The company has developed a manufacturing process that produces high per- formance carbon/polymer pipes that offer improved reliability, increased performance, lighter weight and longer life than conventional un-bonded flexible pipe or steel solutions.
