|
Summary of Field Work: |
This field program will turn multiple secondary junction boxes and over 100 OOI Core instruments as required each year to maintain the Regional Cabled Array. In addition, depending on infrastructure status prior to the field season, 1 or more moorings may need turned. |
|
Summary of Facility Requirements: |
This work requires a global class research ship due to the amount of infrastructure to be turned, the weight of the infrastructure, and number of personnel required (36). The cruise requires the use of the remotely operated vehicle Jason for installation of infrastructure using the underbelly winch and to plug/unplug wet mate connectors - typically >40 dives. |
|
Summary of other requirements and comments: |
Depending on infrastructure status, the ship must be able to handle both a medium-and heavy left OOI winch. |
