OMS Awarded End Dimensioning for Jack & St Malo and Big Foot 20” SCRs
Specialist pipe measurement technology company Optical Metrology Services (OMS) Ltd has two contracts to provide dimensional measurement services on pipes that are destined for use as deepsea risers on Chevron’s Jack & St Malo and Big Foot oilfield development projects in the Gulf of Mexico.
Welspun Corp Ltd, a leading global manufacturer of line pipe, awarded both contracts to OMS, who will measure the pipes on-site at Welspun’s pipe mill in Dahej, India. Whilst OMS engineers have already carried out preliminary measurements at Dahej on test pipes, OMS will measure in excess of 700 production pipes for Jack & St Malo and 550 joints for Big Foot.
Lauren Lionberger, Business Development Executive at OMS’ US office commented: “We are delighted to have been awarded these two contracts, particularly since the Bigfoot and Jack & St Malo projects are really the first two major oil field development projects that have progressed since the Deepwater Horizon oil spill in 2010.”
For end dimensioning of pipes, OMS will utilise its own automatic PipeChecker™ laser measurement tool, which is capable of measuring more than 2,000 IDs and 2,000 OD’s. The tool is accurate to 0.05mm and enables just two OMS staff to measure a minimum of 200 pipe ends in a single shift. This means less time on site, minimising project delays and costs for the customer and reducing pipe fit up and welding issues.
The Jack & St Malo fields are located within 25 miles of one another, approximately 280 miles south of New Orleans, in water depths of 2,100m. The project comprises of three subsea centres tied back to a hub production facility with a capacity of 170,000 barrels of oil and 42.5 million cubic feet of natural gas per day.
The Big Foot oilfield is also situated in the Gulf of Mexico, on the Walker Ridge block 29 field approximately 360km south of New Orleans. The field lies at a water depth of 1,500m and is considered as the eighth largest deepwater oilfield in the Gulf of Mexico.
