Ormen Lange Offshore Project Subsea Development Strategy and Execution

摘要

During recent years the Ormen Lange Offshore Project has been developed in a setting where environmental conditions, technical solutions and execution strategy to a significant extent have been challenged. The environmental conditions are characterized by heavy winter storms with swell, strong current, deep water temperatures below zero, irregular sloping seabed terrain and considerable variations in seabed conditions. The technical solutions have been governed by a subsea development concept tied back to shore over a considerable distance and with a large production capacity. The execution strategy has been heavily influenced by a risk approach both on contract strategy, method and equipment selection, general robustness and follow-up during construction. The success of the Ormen Lange Offshore Project has been highly dependant on a strong project management to accommodate and account for these issues.
