Training creates networks and enables a fresh look at operation
Training and networking. Operators from waste-to-energy plants in Southern Sweden got to know their plants and each other better during a three-week training course held at the three different plants.
The three-week course, which was held at the plants in Ljungby, Eksjö and Skövde, provided the operators with a new network to draw from, refreshed their basic training in the area, and allowed them to take a fresh look at boiler operations.
Custom design training for three different plants
The training was specially arranged by Babcock & Wilcox Vølund and was developed according to the needs of the three plants. Babcock & Wilcox Vølund supplied boilers to all three plants, starting in 2000 (with Ljungby) and 2006 (Skövde and Eksjö), and the plant owners felt it was time for a refresher course.
"We put together special, shared course material, which also dealt with the specifics of each of the three plants. The actual course was held in autumn from weeks 37 to 39, and the operators were split into three groups and spent two days at each plant", explains Hans Lund Sørensen, Senior Service Engineer at Babcock & Wilcox Vølund.
Making knowledge and networking easier to tackle
”The idea behind a combined course for the three plants was to give the participants the chance to expand their networks and to reap the benefits of visiting other plants. Each plant was responsible for hosting a group dinner on the Tuesday evening of the week when the course was being held at their plant. Once you've had the opportunity to meet in this way, it's easier to ring up a colleague at another plant and ask how they addressed a given problem. In addition, the actual training can contribute to optimising plant performance, because the operators gain a better understanding of their boilers. In other words, holding a single class for different plants is advantageous, as long as the basic principles are the same," Hans explains.
Training as a part of the service
Hans and the course instructor, Benny Elbæk Sørensen, plan to carry out similar courses for other clients, if the demand is there. Hans believes it will be, as more and more clients are inquiring about service agreements and training.
Hans points to the plant in Skövde as an example of a service agreement that covers either performance optimisation or training. This year, the plant's management opted for training.
- Training from Babcock & Wilcox Vølund was held over a three-week period at three different plants. The training material was the same for all participants, but contained specifics on each plant.
- Two days of training were held at each plant. To account for shift changes, the operators were split up into three groups.
- The purpose of the training was to freshen up on the original training held when the plant was delivered, as well as to introduce the participants to new networking opportunities.
- In Denmark, boiler operators must be certified after attending a boiler attendant course before they are permitted to operate a boiler at a waste-to-energy plant. In Sweden, however, there are no such requirements, as operators obtain the skills they need through direct training – or from courses held by suppliers or the like.
