Structural Feasibility Study for a Marginal Gas Field
Offshore Timor Sea
Scope of Work
The scope includes developing the structural and foundation design basis for both the Central Processing Platform and Riser Platform, followed by comprehensive structural and foundation design analysis. Additionally, the work involves the computation of structural steel quantities and the preliminary sizing of jacket structures based on the performed analyses. The study supports concept validation and aids in determining the technical and commercial feasibility of platform development in marginal field conditions.

Challenges & Excellence
The project’s primary challenge lies in balancing cost-efficiency and structural integrity for a marginal field, where economic thresholds are tight. Working within the constraints of water depth, environmental loading, and functional platform requirements, NET delivered a robust structural feasibility package. The outcome provided the client with a reliable basis to evaluate investment potential, execution strategy, and long-term field viability, reinforcing NET’s expertise in upstream offshore engineering.
