Impact Dual Energy Saving Technologies on a Frigate’s Duties

Abstract

The adoption of a combination of a wind propulsion device and microbubble drag-reduction on the BMT Venator 110 frigate is explored to identify the benefits at a range of speeds and sea-states. The potential for other propeller benefits in terms of higher efficiency are explored together with the scope for reduced roll and how that may benefit rudder usage and resistance. The likely heel angles achieved with a steady side wind are also considered and their impact on added resistance scoped.The study identifies the beneficial impact of the EST on the ships fuel consumption for a range of sea states and considers the overall beneficial outcomes when time at different sea states and their mid-range wind conditions are considered.
