Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We have used the Sharp in the past for this type of work and require the use of a vessel with similar capabilities (deck space, wire and handling capability, 3.5kHz system, etc.). We will need to open a solicitation to contract for this work and expect that will be done following the end of this current financial year (after Sept 30). |
