| Description |
Alaska's often harsh environment has created unique
challenges for the Oil and Gas industry both onshore and offshore. To better
understand the challenges characteristic of artic environments, their
impacts, and possible solutions, MMS contracted with Det Norske Veritas
(DNV) to provide a workshop on the fundamentals, technical issues, and
remediation of VIV of free spanning pipelines in Cook Inlet, strudel scour
in Beaufort sea, and wind-induced vibrations for elevated pipelines on the
North Slope. |
| Progress |
A two-day workshop was held May 25 - 26, 2004 at the MMS
Regional Office in Anchorage, AK. Representatives throughout MMS and the
State of Alaska participated in the event. A large portion of the material
presented during the workshop remains proprietary to DNV. The
non-proprietary portion of the workshop is provided below. |
