The pipelines on the Mumbai Uran Trunk Line are being constructed for the Oil and Natural Gas Corporation (ONGC) of India.

Oil and gas will be delivered through two new sub-sea pipelines to the Uran onshore processing plant.

Emerson is engineering and delivering its Daniel crude oil and gas metering systems on 12 high performance oil and gas metering skids. The company said these systems would ensure high integrity and accurate, reliable measurement of oil and gas volume, quality, composition and calorific value.

The offshore and onshore metering skids are being installed as the basis for the production measurement and allocation between the production platforms and will be a vital link for the complete production measurement management chain, from production to final reporting of oil or gas sold.

“The system will employ state of the art compact prover technology at the Uran end to prove all the high performance turbine meters for the complete crude oil metering system, including offshore meters,” Emerson said.

“Automatic sampling systems have been provided for high performance water cut measurement. The gas metering system will include the moisture and dew point computation at each of the take-off and receipt points.”

A high performance pressurised, air-conditioned gas analyser cabin will sit on top of the gas-metering skid at the Uran terminal. The gas meter runs will be designed to the latest AGA standard and will be implemented for the first time in the Indian subcontinent, according to Emerson.

The system design will be strictly in conformance with AGA and API MPMS - including all the equations and reporting. Paperless recorders will also be implemented as a part of the local measurement data-reporting requirement.
