Welin Lambie All-Electric Davit Achieves OPC Program Test Milestone

Why It Matters

The milestone validates a greener, more reliable launch solution for the Coast Guard, enhancing mission readiness in harsh maritime environments and signaling a shift toward electric ship systems across defense fleets.

Key Takeaways

• TWPIV 5.0E passed First Article Test in three days
• All‑electric dual‑point design offers 5,000 kg lift capacity
• Software‑integrated control maintains constant rope tension during launches
• USCG production moves to active manufacturing for cutter Pickering

Pulse Analysis

The U.S. Coast Guard’s Offshore Patrol Cutter program has long sought a launch system that can withstand the rigors of open‑ocean operations while reducing logistical footprints. Welin Lambie’s TWPIV 5.0E all‑electric davit answers that call by delivering a dual‑point, high‑torque solution that eliminates hydraulic complexity, cuts weight, and aligns with the service’s sustainability goals. By completing the First Article Test ahead of schedule, the system demonstrates that electric actuation can meet the demanding safety and performance standards required for 5,000 kg over‑the‑horizon boat deployments in elevated sea states.

Technically, the TWPIV 5.0E builds on the proven TWPIV 5.0B platform used on Medium Endurance Cutters, adding a fully software‑integrated control architecture. High‑torque electric winches synchronize both lift points, keeping the wire rope under constant tension throughout launch and recovery. This constant‑tension approach reduces shock loads, minimizes wear, and simplifies maintenance—critical factors for vessels that must remain mission‑ready for extended periods. The 5,000 kg safe working load also expands the Coast Guard’s operational envelope, enabling faster response times and broader mission sets, from search‑and‑rescue to interdiction.

The successful test marks a turning point for defense shipbuilders, signaling broader acceptance of electric mechanical systems in naval applications. As the OPC program transitions to full‑scale production for USCGC Pickering, other branches of the U.S. military and commercial shipyards are likely to evaluate similar electric davit solutions for their vessels. This shift not only supports the Coast Guard’s operational objectives but also drives market demand for sustainable, low‑maintenance maritime equipment, positioning Welin Lambie and Fairbanks Morse Defense as key players in the next generation of naval hardware.
