Allison Companies was sought out by Castex Offshore (a division of Castex Energy) to spearhead and manage the Main Pass 270 B Development Project, which encompassed the engineering, procurement, fabrication, and installation of a four pile platform jacket in the first phase of the project., Phase II of the project included the Engineering, Procurement, Fabrication, Installation and Commissioning of platform topsides, facilities, and pipelines.
The project is owned by project operator Castex Offshore, among a number of private investors (87.5%), as well Petsec Energy (12.5%).
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.
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.
The project was concluded as incident-free, and was delivered successfully on time and on budget.
