Operational demands have been the main driving force behind aspects of modern ship design, namely shorter shaft lines, heavier propellers and engines aft. This has resulted in a greater tendency for vessel shaft lines to bend and break down
Sometimes this presents with common symptoms like noise, vibration, overheating, leaking seals and/or metal particles in oil samples, but shaft lines may also be subject to major incidents like flooding, fires, groundings and collisions – all of which can have catastrophic consequences on a vessel’s shaft line and associated equipment.
In response to the need for expert support following a marine incident, Wärtsilä has launched its new Wartsila Shaft Line Repair Services (SLRS) to deliver a rapid, tailored solution for getting a vessel back in operation. This service is driven by a team of highly specialised alignment and measurement engineers, project managers and field experts offering advanced upgrade and overhaul solutions for all types of rotating and non-rotating equipment.
Together with this cross-collaborative team of experts in marine engineering, Wärtsilä SLRS has access to Wärtsilä-owned manufacturing facilities and a wealth of products around the world. This makes spare part sourcing much quicker and the handling of incidents more streamlined.
When a shaft line is presenting common shaft line symptoms or has been damaged from a major marine incident, Wärtsilä Shaft Line Repair Services’ global team of experts are here to help.
When a common symptom is identified, we carry out an initial investigation and, if necessary, assign Wärtsilä Alignment & Measurement engineers to gather shaft line data from the customer.
A pre-analysis of alignment, torsional vibration and whirling follows, using our patented gyro laser technology, which helps shape the plan of investigation. The data gathered is input into a report which defines the root cause and recommends the best course of action.
With a clear plan in place, the project manager can then schedule overhaul or upgrade work with Wärtsilä Field Services experts and order spare parts through internal or external manufacturers. On completion of the work, our alignment and measurement engineers perform final alignment and load measurements to ensure a vessel’s shaft line is functioning correctly.
Although situation dependent, a standard procedure in the event of a major incident involves a project manager collaborating with Wärtsilä alignment and measurement engineers and, in anticipation of the investigatory outcome, scheduling Field Services resources and new parts from internal or external manufacturers.
A series of inspections, alignment and load measurements, and complex calculations follow, contingent on machining requirements and the conclusions drawn by our experts in analysis. We may also advise on insurance claims and communicate with classification societies.
On completion of the initial investigations, a Wärtsilä SLRS project manager schedules Wärtsilä Field Services for onsite repair work, in-situ machining, welding, underwater servicing and the re-installation of new or repaired parts.
After re-installing the parts, Wärtsilä alignment and measurement specialists take final load measurements and install a Wärtsilä PCBM for monitoring shaft line equipment health and performance, if requested by the customer.
In a modern world of shipping, Wärtsilä SLRS delivers leading expertise across the spectrum of marine engineering and harnesses the power of technology for times when shipowners and operators need it most.
