Nabtesco Corporation (headquarters: Chiyoda-ku, Tokyo; President & CEO: Kazumasa Kimura) and its consolidated subsidiary Deep Sea Technologies, Inc. (DeepSea) have obtained type approval for their respective new products TELEGRAPH AGENT™ and HyperPilot™ from DNV AS, the world's leading classification society in Norway.

It is currently common that the vessel's crew adjusts the RPM of the main engine by manually operating the handle of the bridge maneuvering system to control vessel speed according to the voyage schedule. However, manual operation sometimes fails to maintain the planned vessel speed due to external factors, such as weather (wind direction, current), affecting the time of arrival and fuel consumption. To maintain an optimal vessel speed, frequent handle operation is also required, which is a burden on the crew.

Nabtesco introduced its first collaboration system co-developed with DeepSea, which the Company acquired in 2023. "HyperPilot" receives the optimal route and vessel speed plan provided by the Optimal Operation Support Services one of DeepSea's major software applications, and outputs the vessel speed proposed based on the current vessel position to Nabtesco's "Telegraph Agent". This allows the engine's RPM, which corresponds to the planned vessel speed, to be automatically adjusted in real time.

With the acquisition of type approval, the Group will expand the offerings of maritime solutions that enable autonomous vessel navigation at an optimal speed to reduce crew workload, fuel consumption, and GHG emissions.
