Sea Refueling, Smarter USV Operations

As USV fleets grow, so does the need for efficient, autonomous operations. Refueling at sea removes the need for Launch & Recovery during missions—extending endurance and mission flexibility.

Selartec’s TCCD and dedicated L&R systems enable real-time data transfer and refueling with minimal impact on both USVs and motherships—no special equipment required.

THE CHALLENGE- STERN RAMPS L&R

Successfully navigating a boat up the ramp requires advanced driving skills due to the high relative speed, resulting in substantial kinetic energy and impactful loads. The increased relative velocity induces bow motions, leading to positioning inaccuracies and heightened slamming loads on the stern ramp. The critical phase is when the boat, with higher relative velocity, maneuvers aft of the ship, requiring precise handling to fit into the notch. However, turbulent wake and the ‘sloshing’ effect diminish maneuverability significantly leading to collisions with the ship’s stern.
Consequently:

Entering the stern in high sea states is perilous and often requires multiple attempts.
The boat operator needs exceptional skill, daring, and extensive training.
Recovering a USV up a stern ramp is practically impossible in high sea state using this old-school methodology
