Successful Propeller Repairs on Tugboat Wilbur

04.05.2015 | #Repair, Modification, Optimization

We are pleased to share the successful outcome of the propeller repair on our tugboat, Wilbur. Managed with utmost care and precision, this project showcases the exemplary work conducted by ADRIATIC PROPELERI

The Issue:

Our tugboat Wilbur experienced significant vibration issues stemming from an incident where a towing wire accidentally got entangled in the propeller. The towing wire was cut, but the incident resulted in severe damage to one of the four blades of the 115” x 90” RH propeller. One blade exhibited a substantial bend, necessitating immediate attention.

Temporary Solution:

Due to operational commitments, immediate docking for repairs was not feasible. Therefore, our technical manager decided to continue operating the tugboat at a safe, reduced speed to prevent further damage to the onboard machinery. This temporary measure allowed us to maintain operations until the next scheduled dry docking.

Repair Process:

During the planned dry docking in September 2014 at the Dakarnave shipyard in Senegal, several companies were consulted for the repair. Based on their timeframe and capabilities, ADRIATIC PROPELERI was selected to undertake the task.

  • Docking and Dismantling: The shipyard team was responsible for dismantling and fitting the propeller post-repair.
  • Repair Duration: The entire repair process took seven days.
  • Measurement and Balancing: The propeller was meticulously measured before and after the repair, ensuring it matched the original specifications. Balancing was performed according to the rules.

Post-Repair Performance:

Following the dry docking, sea trials were conducted at various speeds, including the engine's nominal speed. The trials revealed no abnormal vibrations, and a significant increase in speed was noted. The repairs were carried out to our complete satisfaction.

Conclusion:

We highly recommend ADRIATIC PROPELERI for their exceptional work in propeller repairs. Their expertise and attention to detail have restored the Wilbur to optimal operating condition, ensuring safe and efficient performance.
