Introduction

This project was defined with the objective of conducting engineering studies and designing the supporting structure for the pipeline corridor as well as the flare stack platform, utilizing a pile-and-steel deck system. As part of the scope, the 210-meter-long pipeline route was studied and designed, including the necessary steel piles, connecting beams, and truss structures. In addition, the flare stack support platform was designed and analyzed with a base dimension of 15 × 15 meters and a height of 107 meters, providing the capacity to accommodate a 170-ton flare stack on top of the pile-deck structure. Throughout the construction phase, the engineering team provided technical support to the contractor and delivered on-site specialized consulting services. The technical complexities of this project were primarily driven by the challenging seabed conditions in shallow water, which limited the penetration depth of the piles. The installation of a massive 107-meter-high, 170-ton flare stack on a pile-supported steel deck further emphasized the need for a highly accurate and reliable design. Moreover, in order to reduce construction and installation costs, the design approach was optimized so that the majority of structural components could be fabricated onshore, thereby minimizing expensive offshore works. The platform geometry was also engineered to ensure an even distribution of loads across the piles, while the pipeline corridor was designed with a focus on optimizing the costs associated with piles, connecting beams, trusses, and construction activities.
