ZF Retractable Thruster for R/V Roger Revelle

The research vessel Roger Revelle is currently go- ing through an extensive mid-life re? t. One of the upgrades to the vessel is the installation of telescop- ing thruster technology from ZF Marine.

The R/V Roger Revelle is a globally capable oceanographic research vessel, designed as a plat- form to support many different facets of ocean- based scienti? c research. The vessel is owned by the US Navy and operated by the Scripps Institute

Ashtead of Oceanography under a charter agreement with the Of? ce of Naval Research.
