When on-site machining, alignment services, blade repairs, or other field repairs are required, MarineShaft’s mobile service team is prepared to deliver high-precision work at any project location. The following two case studies demonstrate MarineShaft’s ability to mobilize quickly and perform expert repairs under demanding conditions.
Case Study 1: On-Site Rudder Machining and Laser Alignment in Iceland
MarineShaft recently completed a successful on-site service assignment in Iceland. Within three days, two service engineers carried out precision alignment and machining on a vessel’s rudder equipment.
Challenge:
The vessel’s rudder line was misaligned.
Solution:
MarineShaft machined the rudder heel housing on-site to restore proper alignment. Following precision realignment and machining, a new bushing was mounted in a clean, correctly machined seat—ensuring long-term reliability and optimal performance.
Scope of Work:
- Measuring the rudder line from the steering gear to the rudder heel
- Machining the rudder heel housing to correct misalignment
- Re-measuring the rudder line post-machining
- Machining the rudder flap bushing seat for precise fitting of the new bushing
Case Study 2: On-Site Propeller Blade Welding in Norway
With extensive welding experience and class-approved procedures recognized by leading Classification Societies, MarineShaft recently conducted emergency repairs on a Norwegian vessel’s four-pitch propeller blades following a wire strike incident.
Challenge:
The propeller blades sustained severe damage, requiring structural restoration through welding.Solution:
The vessel docked at a local shipyard and preferred an on-site repair to minimize downtime. MarineShaft dispatched field engineers equipped with class-approved welding materials and all necessary equipment.Because these materials are kept in stock, MarineShaft was able to mobilize swiftly and begin repairs without delay, minimizing operational disruptions.
Scope of Work:
- Initial inspection and measurement of blade geometries
- Grinding of damaged edges in preparation for material rebuild
- Welding to restore damaged edges on all four blades
- Grinding of welded areas to match the original blade geometry
- Liquid penetrant inspection to verify repair integrity
The repair was completed within five working days.
MarineShaft is a repair company located in Denmark. They specialize in repair and replacement of propulsion and rudder equipment, providing swift in-house and on-site repair solutions.
