Digital Technologies Used in Constructability Design for Surface Installations

During basic design development for new FPSO projects in Brazilian pre-salt exploration, digital technologies were employed, in order to achieve constructability design requirements, construction and commissioning specification checks. Due to its benefit cost, schedule, quality, and overall project objectives and deep influence in platform safety and operability, in a process explained in Figure 1. Those digital technologies, such as the use of databases, computer aided engineering (CAE), analysis tools, 3D simulations and consistency check, were identified in constructability reviews and were developed to achieve the best constructability procedures and solve construction inconsistencies between several involved disciplines in posterior detailed design, procurement and commissioning phases. This manuscript aims to present the use of digital technologies to support constructability analysis in offshore oil & gas production facility – surface installations - projects of Petrobras.
