ABU DHABI, UAE – Amarinth has delivered API 610 OH2 pumps in various exotic alloys to ZADCO for an offshore pilot plant at Zirku Island, Abu Dhabi.

The new plant is 140 km (87 mi) northwest of Abu Dhabi. Zirku is the main industrial base for processing, storage and export of oil from the offshore Upper Zakum , Umm Al-Dalkh, and Satah fields.

According to Amarinth, ZADCO needed a produced water treatment on a tight lead time to meet the plant’s operating deadline. The filtration system pumps had to be of a low shear design to prevent emulsification of the oil and water, otherwise the process would be ineffective.

Also, the produced water had a high hydrogen sulfide (H2S) content, so the pumps had to be manufactured in a high nickel alloy for counter-corrosion purposes.

This is the first pilot project in the Satah full field development project.

ZADCO has since contracted Amarinth to upgrade API 610 VS4 vertical pumps which it first supplied to the company in 2009 with new flow sensors and external flush lines.

The sensors are to ensure that the pump bearings do not run dry, a major concern in hazardous environments where a pump failure could lead to loss of life.
