The Dan chalk oil field is in shallow water 120 miles west of Esbjerg. It has been developed in phases with 12 platforms, 38 currently active oil wells and 33 active water injectors.
Three Girdlestone 980 API 610 pumps, part of the oil and water cyclone separator system, had reached their end of their lifespan. Girdlestone no longer exists, so the operator sought alternative pumps without the need for costly modifications to pipework and fittings and associated production downtime.
Amarinth proposed a version of one of its own centreline pumps that would be designed to the API 610 edition to match conditions applicable to the original Girdlestone pumps. The company also engineered its systems to be dimensionally interchangeable with the existing pumps to minimize required changes.
The replacements, manufactured to ATEX requirements with Plan 31 seal arrangements and associated gauges, were delivered within a 26-week lead time and in line with the maintenance window, ensuring minimal disruption to operations on the platform, Amarinth said. They should operate reliably over the coming decades, it added.
