Presented by Mahesh Sonawane, Sr. Engineering Specialist

Wednesday, June 17, 2020 | 3:00 PM GMT / 9:00 AM CDT

In this 2H Offshore webinar, you will learn about the complexities of jumper VIV analysis, the principles of VIV fatigue analysis methods, and the key challenges involved in optimizing a VIV suppression solution. We will also discuss striking a balance between strength and fatigue design requirements and the current limitations in design code.

Detailed Event Outline

Subsea rigid jumpers are designed to meet numerous criteria including thermal and pressure effects, environmental and riser/pipeline interaction loads, slugging, and other field-specific requirements. Jumper VIV fatigue is another concern in fields with strong bottom currents. Without the benefit of detailed VIV fatigue analysis, designers must rely on experience and engineering judgement on the placement of strakes if VIV is identified as a concern. VIV mitigation is even more challenging because jumpers can contain numerous long and short design options to accommodate tolerances for subsea well locations and installation tolerances of subsea PLETS and manifolds.

In this webinar, we will talk about complexities involved in jumper VIV analysis, the principles of VIV fatigue analysis methodology and the key challenges involved in optimizing an acceptable VIV suppression solution. A case study describing how multiple subsea M-shaped jumpers designed for a sour service application in the Gulf of Mexico will also be presented.

This webinar will highlight the trade-offs that are required to strike a balance between strength and fatigue design requirements, and will also discuss about the current limitations in design code that relies on standards developed for pipeline application.

Learning Outcomes

  • Understand VIV fatigue analysis methodology for rigid jumpers
  • Learn how to solve the key challenges in design optimization
  • Understand the recommended modification to VIV fatigue design methodology specified in design code

This webinar is ideally suited for subsea engineers, subsea connections systems/package engineers, project managers on subsea systems and anyone interested in understanding the principles and challenges on VIV fatigue assessments.
