Keystone provided fabrication and loadout engineering services for the Williams Gulfstar 1 FPS Topsides (approximately 8000 tons). Keystone performed the structural analysis for construction and loadout conditions. Engineer the loadout of the Topsides required design of a skidway, pulling/skidding, ballasting, and skidway load spreader systems. Keystone designed a project-specific skidding system which allowed the fabricator to skid the topisides with 60’ deck leg spacing on existing yard skidways that were set for a 69’ deck leg spacing. By utilizing the fabricators existing infrastructure loadspreader beams, and other items, Keystone’s solution reduced costs, saved time, and improved the overall efficiency of the project.
