Project Number 604
Date of Summary March 31, 2008
Subject Evaluation of Fatigue Life Models and Assessment Practice for Tension Leg Platforms (Phase 1: Tendon System Fatigue)
Performing Activity Texas Engineering Experiment Station (TEES)
Principal Investigator Lance Manuel
Contracting Agency Minerals Management Service
Estimated Completion August 31, 2008
Description The objective of this project is to evaluate the state of practice in fatigue assessment in the offshore industry today. Of interest is an understanding of how fatigue life calculations are undertaken and how both load and resistance side uncertainties are employed in design for fatigue. The project will be carried out in two phases. In Phase 1, fatigue assessment of TLP tendon systems will be the focus. Phase 2 (to be proposed in the 2008-2009 funding cycle) will address fatigue of moorings, risers, and connectors.

This objective will be accomplished via the following tasks:

  1. Conduct Literature review
  2. Definition of Illustrative TLPs
  3. Evaluate Alternative Fatigue Resistance Models
  4. Evaluate Alternative Fatigue Load Models
  5. Assess Fatigue Life
  6. Conduct Critical Review and Interpretation of Results
  7. Prepare Final Report
Progress Contract awarded August 30, 2007. Student researcher has been identified. Task 1 is completed.
