Project Number 485
Date of Summary December 7, 2004
Subject VIV Pipeline Span/Riser Training Seminar
Performing Activity OTRC
Principal Investigator Ward
Contracting Agency Minerals Management Service
Completion Completed
Description MMS Engineers are faced with approving a variety of projects that can be influenced by VIV (Deepwater risers, Pipeline spans over irregular bottom topography subjected to strong bottom currents, onshore elevated pipelines subjected to strong winds). MMS engineers need to be aware of the potential for VIV to damage such structures and various options that can be useful in mitigating VIV. Seminars will be developed and delivered to MMS engineers to provide a basic understanding of VIV, describe the potential for VIV to occur and how it might damage such structures, and mitigation strategies that might be proposed for various offshore projects.
Progress Project completed on December 7, 2004.

A two-day seminar was held in New Orleans on December 2-3, 2003 for MMS engineers to address VIV issues and influences on offshore oil and gas operations.  The seminar materials are presented in the REPORTS section below.  An outline of the presentation follows.

SESSION 1 - FUNDAMENTALS OF VIV- DALTON

SESSION 2 – VIV AND DEEPWATER RISERS & TENDONS - LEVERETTE

Section 2a – VIV Applications to Deepwater Risers

Section 2b – Analysis of TLP VIV Responses to Eddy Currents

Section 2c – A High Mode Number Field Experiment - Leverette

SESSION 3(a and b*) – VIV APPLICATIONS TO DEEPWATER PIPELINES – BROWN

* The seminar material is presented in two sections (3a and 3b) due to file size.

Due to a lack of video file support, some of the video presentations made during the two day seminar could not be included.
