THRUSTER BLADE
REGENERATION CENTER
In order to meet the customers expectations, BOTA TECHNIK has developed the infrastructure and facilities to provide top quality overhaul of bow thruster and other propulsors. The area of the modern THRUSTER BLADE REGENERATION CENTER
is 1248m2, which includes:
- thruster repair station,
- warehouse space,
- very well equipped tool store,
- welding and grinding shop,
- machine station,
- test stand for thrusters.
THRUSTER BLADE REGENERATION CENTER is additionally equipped with a lifting system:
- gantry with a lifting capacity of 10/5 t, two hooks
- gantry with a lifting capacity of 25/12,5 t, two hooks
- four cranes with a lifting capacity of 3.5 t.

We can also perform a general overhaul in our modern THRUSTER BLADE REGENERATION CENTER in Gdansk.
The BOTA TECHNIK team removes the thruster from the vessel (in any port or shipyard), which is then transported to the THRUSTER BLADE REGENERATION CENTER where the necessary repair works are performed. After the overhaul is completed, the thruster is reassembled on the vessel wherever he is.
Standard technological process for overhaul of the thrusters in THRUSTER BLADE REGENERATION CENTER:
- remove of the thruster from the vessel,
- dismantling and verification of the technical condition of thruster on THRUSTER BLADE REGENERATION CENTER,
- measurement and adjustment of clearances and replacement of bearings, seals and other necessary parts,
- assessment of tooth contact and the condition of the bevel gear teeth,
- a team of technologists and constructors from our design office supervises the project and supports its implementation in terms of performing of measurement cards and necessary elements if necessary,
-
regeneration of blades,
- by surfacing,
- by welding the insert,
- blades measurement, balancing and polishing.
- installation unit on the vessel and carrying out tightness and commissioning tests.
Test bench :
We enjoy the trust by a group of many shipowners for whom we conduct this type of operation in any location (disassembly and assembly on the vessel). In addition, we conduct thruster repairs for our clients, which will later be secured, stored and waiting for “their time” as spare unit.
In order to provide a comprehensive repair services we have built a test bench to verify the correct operation of thrusters. Designed and built by Bota Technik test bench is one of the few devices of this type in the World. Adequate rigidity is ensured thanks to 11 tons steel construction which is permanently mounted on a specially designed foundation. The test bench has its own power hydraulics, automation and diagnostics systems. This infrastructure allows us to carry out tests of transverse thrusters FPP and CPP type as well as other types of thrusters that are flange mounted.
