Project Challenge

The project was dependent on the discoveries of the drilling program. The needs and ultimate design of the platform topsides remained undetermined until after the testing period, which was completed during November 2016. Scheduling was critical, as the engineering portion of the project – including the facility requirements process – could not be initiated until testing was concluded.

Solution

Allison Companies spearheaded and managed all phases of the project from conception thru installation and commissioning. The “B” platform was installed in water depth of 215ft, with an original design capacity of 50 million cubic feet of gas per day and 1100 Barrels of Oil per day. The design included accommodations for potential future increased well production. The facility was brought online in late November 2017.

Result

The project was concluded as incident-free, and was delivered successfully on time and on budget.
