The Alliance Engineering Deepwater Business Unit provides engineering, procurement, and construction support for offshore oil and gas production deepwater facilities.  We are well known for the highly-optimized, lightweight, single-lift, fast-track topsides designs on TLP’s, SPARS, Semi’s and others.  Our single-lift topside designs achieve production rates usually associated with larger, costlier multi-lift designs; this saves our clients significant money, and often shortens the amount of time between sanction and first oil. Alliance also provides engineering and design services as needed for larger topsides installations, including multiple-lift topsides modules.

Alliance Engineering’s lightweight topsides have been an integral part of record-breaking projects, including: World’s Deepest TLP, World’s Deepest Spar, World’s Deepest Production Platform, Deepest Dry Tree, 1st Dry Tree Mini-TLP, and 1st Mini TLP’s.  Our topsides have been installed on platforms all over the world.

Whatever the project, Alliance’s goal is to deliver a cost-effective, safe and reliable system, on schedule, beating industry benchmarks.
