Tridentis was recently awarded two major engineering task orders from Puget Sound Naval Shipyard (PSNS) in support of the PSNS Marine Design and Engineering Services Contract. The primary purpose of these task orders is to perform ship checks, perform engineering analysis and calculations, and develop two-dimensional Computer-Aided Drafting (2D CAD) drawings for removal and installation drawings in support of Ship Change Documents (SCDs) for both the USS THEODORE ROOSEVELT (CVN 71) and USS ABRAHAM LINCOLN (CVN 72). Within three business days of these tasks being awarded, Tridentis had over 20 of its engineers onboard the vessels performing ship checks, thus assisting PSNS planning yard with maintaining schedule.
In support of ship checks on the CVN 71 and CVN 72, we delivered a ship check report for each assigned ship check package. Ship check packages contained a complete set of ship check data, sketches/drawings, photographs, and reference drawings. Each package included a brief summary that identified any problems encountered, POCs, and follow technical code requirements. Tridentis utilized Naval Architects, Structural, Mechanical, HVAC, Piping, Electrical and Electronic Engineers to support this task while developing or modifying over 110 drawings. Additional work included performing HVAC calculations and shock analysis, using Finite Element Analysis (FEA) tools on structural foundations and equipment, weight and moment calculations, and 3D Laser scanning for documenting interferences and maintaining quality control. Tridentis provided a diverse group of engineers to solve highly complex problems utilizing an integrated team approach across all engineering disciplines.
