At the Bratyev Nobel shipyard (part of the Kalashnikov concern), loading of two main engines rated at 2 × 1800 kW onto the icebreaking tug Narvskaya Zastava of Project 3262, class KM Arc4 [1] R3-RSN AUT2 Tug, has been completed. The engines were placed on a prepared foundation in the engine compartment.
Work is now underway on the vessel to install the main and auxiliary equipment, as well as to assemble and integrate key systems. In parallel, electrical installation, painting, insulation, installation of deck equipment, and towing and mooring mechanisms are being prepared. The tanks are being prepared for the main tests.
Construction is proceeding according to plan, with technical readiness exceeding 40%. The customer is the St. Petersburg Committee for Nature Management, Environmental Protection, and Environmental Safety.
The manufacturer emphasizes the complexity of the project: with a length of 42.5 m, the tug is equipped with a lifting wheelhouse, folding masts, and antennas for navigation under the Neva bridges.
