SANDEFJORD, Norway – Stauper Offshore has secured a new patent for the upgrade of produced water treatment systems, based on its standalone oil and water separation vessel, the Stauper compact flotation unit (CFU).
The new patent, the company said, describes how the core component of the CFU can be installed into other vessels in modules, through the main way, without the need for recertification of the vessel.
“Operators are increasingly seeking to extend and maximize existing production assets,” said Rune G. Nilssen, managing director.
“As fields mature, water-cut increases and separation challenges may come as a result. Our retrofit solution will allow operators to improve efficiency of existing equipment while solving separation and environmental challenges.”
The patent allows for a wide range of vessels to be upgraded, including existing CFUs, degassers, and water knock-out vessels. Stauper has retrofitted two CFUs at Equinor’s Martin Linge platform in the Norwegian North Sea, converting the systems to the company’s patented and Equinor-qualified design.
A recent study requested by an operator seeking to upgrade existing CFUs suggested the retrofit could save up to 50% of costs compared with installation of new equipment, Stauper said, adding that field work can be completed in a few days, also limiting costs.
