Case study 04 / Topsides & equipment package
A six-figure barrel-per-day topside — sized, drawn, and out to tender.
Scope
Basic engineering and design services for the supply of a 100,000 BPD seawater injection topside destined for the Gulf of Mexico. The package needed to be defined to a level the contractor could take to vendors with confidence — sized equipment, full drawings, datasheets, layout, a defensible cost to build, and a bid evaluation framework already in place when the RFQs went out.
Approach
Seawater injection topsides live or die on the deaeration train and the rotating equipment. The work front-loaded technology selection — coarse filtration, fine filtration, deaerator tower, vacuum package — and converged on a layout that fit the host topside's footprint while keeping rotating equipment accessible for maintenance.
Process simulation pinned the operating envelope; equipment sizing turned that into datasheets; layout drawings turned the datasheets into a real package; and the RFQ pack went out to vendors with bid evaluation criteria already aligned to the project's CapEx target.
Engagement
Lead Process Engineer for the basic engineering phase. Owned process design, equipment sizing across static and rotating, technical proposal authoring, and the cost-to-build estimate.
