| Estimated Completion |
Completed |
| Description |
This was a Joint Industry Project
(JIP). The objective was to determine the ice loads and motions likely to be experienced
by a cable-moored platform subject to a moving ice flow or field of ice rubble. Presently
such data are scarce, although cable-moored platforms are being considered as work
platforms in Arctic waters. The project evaluated the ice forces, moments, and platform
motions resulting from ice impact. Parameters to be varied will be thickness, speed, and
strength of the ice masses. A prototype model of the Gulf Canada platform `Kulluk`
was used in a tank test to gather data to compare with actual field measurements taken from
the `Kulluk.` |

Completed. The proprietary period on the
reports has ended. |
