ECF help to upgrade APACHE North Sea oil field


ECF help to upgrade APACHE North Sea oil field

ECF Special Alloys, in conjunction with SPX Plenty and Petrofac have upgraded the Forties Alpha and Delta platforms in the Apache North Sea Oil Field.

Working on the Petrofac ’debottlenecking upgrade project’ ECF and SPX have manufactured new Production Gas Scrubbers for the Alpha and Delta platforms.
Together the engineers have rebuilt the existing mothballed Production Gas Scrubbers, originally manufactured from Carbon Steel back in the 1970’s with new ones now fabricated from Duplex 2205.

Due to declining reservoir pressure in the APACHE field over the years, artificial lift in the form of Deep Gas Lift (DGL) and down hole pumping was required to maintain production. 

The Petrofac ’debottlenecking upgrade project’ was designed to increase the DGL rate and therefore the production rate.

Our engineers at ECF Special Alloys developed brand new weld procedures specific for this offshore project to enable standard Duplex 2205 weld metal to meet ASME G48 corrosion testing.
