The aim of the project is to replace the plating at the pressed tug TR 436. The original plates of the vessel’s bottom plating are corroded and attenuated or damaged by navigation during the years of operation. This adversely affects the floatability of the vessel and threatens to sink in the event of a navigational accident. The validity of ship documents is established by the ship register until 24.5.2020. One of the conditions for ensuring the continued safe operation of the vessel is the plating and surface treatment.
