Hawboldt Industries System / Package
SPRL-4mT CTD LARS
Ceiling-mounted CTD rosette launch and recovery system designed to DnV 2.22, extending outboard through vessel side doors.
Description
The SPRL-4mT CTD LARS deploys and retrieves a CTD rosette together with a CTD winch. It mounts on a ceiling foundation and extends outboard through the vessel's side doors; the boom stays horizontal during cast and tow operations and luffs down to deploy and retrieve the package. In automatic mode the winch follows the LARS motion. Hawboldt CTD LARS have been deployed in Antarctica.
