They are fixed tunnels installed in the hull of a ship below the water line for and/or aft and are designed to push a ship sideways during slow speed maneuvering. Thrustmaster offers a great line of hydraulic tunnel thrusters from 35hp (25kW) to 3,000hp (2250kW).  They Many dynamic positioning solutions include the transverse tunnels in their calculations. Many of Thrustmasters models already have ABS approval.
