Metalock Brasil was contracted by a company for which it is the authorized representative in the country, a renowned Spanish manufacturer of electric motors, to carry out an extensive maintenance scope on all the brand’s equipment installed on a flotel (offshore support and accommodation vessel) during its docking at Estaleiro Atlântico Sul, in Suape, Pernambuco.
Metalock Brasil’s technicians conducted dimensional inspections of the shafts and end caps, as well as replaced the bearings of seven azimuth thruster motors and two propulsion thruster motors.
During the dimensional analysis, three end covers showed wear and measurements outside the tolerance in the bearing housing area. Faced with this challenge, Metalock Brasil quickly transported the covers to its workshop in Santos (São Paulo), where they were repaired through machining and bushings. In a record time of six days, the covers were returned and installed on the motors onboard.
Additionally, Metalock Brasil performed a complete electrical inspection, including insulation measurements, phase-to-phase resistance testing, and air gap verification, ensuring the full functionality of all the motors, including eight more generators manufactured by the same manufacturer and installed on the vessel.
To ensure the excellence of the service provided, a Metalock Brasil technician boarded during the final phase to accompany the sea trial conducted in Rio de Janeiro, where an SPM (Shock Pulse Method) vibration analysis was performed on all the inspected motors and generators, confirming the equipment’s good performance.
All service reports were approved by the client and the manufacturer, allowing the vessel to resume operations with total safety.
