Subsea Model-Based Design Approach Facilitates Decision-Making

Computer model-based design gives offshore engineers a way to explore a variety of alternatives and options for equipment and systems. Work by ABS on developing modeling and simulation capabilities has paid off with insights that support ABS Rule and Guide development for subsea, offshore and marine applications – and are available to help other industry stakeholders in their design and problem-solving efforts.

ABS simulation models of stepouts coupled to tiebacks allow engineers to explore the interaction of electrical power systems with tieback and pumping/compression stations and to study power quality phenomena during normal operation scenarios as well as during unusual events.

As offshore power system requirements are challenging the functional limits of traditional equipment and systems, ABS is also developing models of offshore and marine power systems operating in a variety of advanced configurations. These models allow engineers to simulate equipment and system performance under different normal and fault operating conditions and understand the interaction of multiple energy sources.

The ABS simulation project is part of ongoing multiyear research targeting subsea power systems, power systems associated with dynamic positioning vessels and other innovative technologies.
