Our experience allows us to carry out overhauls of thrusters:

In addition, we can perform a comprehensive renovation in our modern workshop
in Gdansk. BOTA TECHNIK employees remove the rudder from the unit, transport it to the workshop and carry out the necessary renovation work.
We have our own machine park and Design Department that support repairs, thanks to which we ensure the highest quality of work in a short time.
Depending on the clients’ needs, we send a specialist / service engineer for supervision, or a full team consisting of a service technician and fitters to carry out a comprehensive renovation.
At the shipowner’s request, we can analyze the oil sample taken from the rudder or tank.
