Tieback analysis

We’re market leaders in tieback analysis, having completed over 400 separate projects for leading operators across the world.

Why our tieback analysis?

A key focus of tieback engineering is the pre-planning. Our involvement in over 400 tieback engineering projects worldwide means we understand all the considerations to think about when looking to tieback a well. Our in-house analysis team can run this in-depth analysis and then seamlessly work with our in-house tieback engineering experts to ensure findings are not only used, but understood and implemented.

  • Tailored approach
  • Leading edge technology
  • Complete managed service

We always endeavour to tailor each analysis project using both our customer’s requirements and our own experience. This reduces unnecessary costs, while providing valuable insight into the tieback operations when accounting for global dynamic loads.

Common tieback analysis includes but is not limited to:

  • Vortex Induced Vibration (VIV) assessment – to assess the likelihood of VIV lock-on and whether VIV suppression devices and/or whether a VIV fatigue assessment is required.
  • Strength and Stability analysis – to determine the acceptability of the conductor, connectors and surface equipment connections / flanges under prescribed storm conditions.
  • Wave Fatigue Analysis – to estimate the conductor fatigue damage from repeated wave loading. The damage from wave fatigue will be combined with damage from VIV fatigue, if appropriate, to calculate the lifetime of the well.
  • VIV fatigue assessment – to compute VIV fatigue damage of the conductor if VIV lock-on was predicted from the VIV assessment. Provide recommendations for using VIV suppression devices.
