Quiet and Clean

Powered by a diesel generator, the M40P has a single lifetime of up to 24 hours, while it can operate continuously for weeks by refueling.

The generator can be turned off when surveying to provide a quiet and zero-emission operating environment for the equipment to guarantee data accuracy.

Exceptional Maneuverability

The configuration of twin engines and twin propellers, combined with the catamaran shape, elevates its maneuverability when navigating closely around foundations constructions for zoom-in inspection.

High-precision positioning and advanced navigation control algorithm minize risk of collision.
