Wrapping of a rudder shaft at QuantiServ Italy

New Video: Wrapping of Propeller Shafts and Rudder Stocks

Shaft wrapping is an activity that our specialists perform on a regular basis, mostly for new ships while they are under construction.

Whenever the design of a vessel mandates that the propeller shaft or rudder stock lies exposed to open seawater, then it should be protected against electro-chemical corrosion. This type of corrosion occurs in the presence of (sea-) water and air (or dissolved oxygen) and the usual way of avoiding it is to coat the shaft with a protective layer of fiberglass.

The following picture shows an example of a rudder stock showing severe signs of corrosion. This is the very outcome that wrapping prevents.

The wrapping process as such is very well established and the results are excellent. During dry docking, we have recently inspected some shafts that we have wrapped ten years ago. We found the wrapping in still perfect condition.

QuantiServ’s In-situ Machining Specialists are Very Highly Trained

The last few weeks have been a busy period for our internal trainers at our in-situ training center in Gothenburg, Sweden. Courses were scheduled back to back. In-situ machining colleagues from around the world were undergoing refresher training on a variety of topics: in-situ crankpin machining, in-situ heat treatment (annealing), engine block machining, etc.

At QuantiServ, we very highly value formal training. All our in-situ machining specialists undergo rigorous training and assessment when they first start to work for us. And it does not stop there. As we constantly keep on further developing and improving our tools and processes, we regularly call the in-situ machining specialists that normally are stationed all around the world back to our in-situ training centre in Sweden to equip them with the most updated skills and knowledge.

This was the case with colleagues from Italy and Brazil that joined a training course last month. Even though some of them already work for us for ten years or more, there are always new tricks that they can pick up. A lot of knowledge sharing and networking takes place during these courses too. The trainees meet with our designers and tool developers and provide them with valuable feed-back and experience from the field. This information then flows into the next generation of tools so they become ever better and more efficient. It is highly trained machinists and cutting edge tools that keep QuantiServ at the forefront of the in-situ machining industry.
