Alternative Oil Export System

Costain was contracted by Ithaca to define the optimal short-term solution to export oil from the Stella field.

Advisory and concept development

The interim resolution was to allow the continued negotiation of a pipeline routing which could accept wax deposits and associated pigging. Costain assessed all the alternative oil export options including: 

  • A subsea storage tank
  • Floating storage units, both ship-shaped and cylindrical
  • Spar buoy
  • SAL moored shuttle tankers
  • DP shuttle tankers with various riser systems

The assessment included the overall project costings over varying time frames and assessed the impact on production efficiency

 

We identified a SAL system operated with DP shuttle tankers as the optimum short-term oil export system for the project. The recommendation is cost effective and allows flexibility for future solutions.
