Advice has been provided to one of the world's largest manufacturers of chemicals and oil products on the use of an on-line oil-in-water analyser for reporting the discharge of produced water from an unmanned platform.
“The client was looking to gain approval from the Department for Business Energy & Industrial Strategy (BEIS) for the use of online oil-in-water monitoring for produced water discharge reporting at a Normally Unmanned Installation (NUI),” says Principal Consultant, Dr. Ming Yang. “Their objective is to utilise an online oil-in-water monitoring system that will work safely, reliably and accurately with little or no physical intervention or maintenance.”
Ming and his team have provided comments on the selection of monitoring technology for the unmanned installation, along with guidance and advice on how evidence should be gathered and provided to BEIS to prove that the use of online oil-in-water monitor for produced water discharge reporting is feasible. Methodology has also been developed for extracting data from on-line equipment.
“This project is an important step forward in applying online oil-in-water monitors for reporting the discharge of produced water from unmanned installations.,” says Ming. “The wider importance of this work comes down to efficient operations and therefore reducing costs. Everyone in the industry is concerned about operating costs. Unmanned production is a key way to reduce these costs.”
According to Ming, up until now, there have been very few instances in the North Sea and indeed around the world where an online oil-in-water monitor has been used and accepted for regulatory reporting purpose for the discharge of produced water. Moreover, although BEIS guidance is available for accepting an online oil-in-water monitor for reporting purposes, it was developed with manned installations in mind. For an unmanned installation, it cannot be directly applied.
