Managing deepwater intervention vessels offshore Angola can save costs

摘要

The scarcity of intervention vessels continues to drive up day rates, adding significant costs to field operations offshore Angola. An analysis of the future demands for vessels in deepwater off Angola shows where operating expenses could be reduced. The analysis formulated a technical definition of intervention required for individual tasks, and forecast the overall demand for specific units. Vessel specifications can be used to screen the existing fleet and to help select those best suited for subsea/well intervention in Angola. The results also provide a starting point for vessel fabrication or modification specifications.
