Safe leisure parks thanks to comprehensive risk analysis

In amusement parks, visitors can experience thrills and leave everyday life behind them. In Germany and many other countries, it is TÜV NORD which looks after their safety.

Amusement parks are popular destinations across the world. Families with children in particular appreciate the many attractions on offer for old and young alike. But if roller coasters, roundabouts and the like are to be fun, they have to be safe.

As the “higher, faster, further” motto also applies to amusement parks, it is essential that park operators regularly service their rides and identify and reliably eliminate the risks. After all, an accident can hit them where it hurts, destroy their reputation for years on end and deprive them of their livelihoods – not to mention the tragic consequences for the victims. The EU requires all operators to perform regular safety checks but does not define the intervals at which they are to be carried out.

Maintenance alone is not sufficient

“In general it’s safe to assume that parks check their rides annually and service them regularly,” says Kees Bakker, who, as Senior Inspection Engineer at TÜV Nederland, undertakes risk analyses at 45 amusement parks and 10 water parks in the Netherlands, Germany and as well as other countries in Europe, Asia and the Americas.

Risk analysis goes beyond the mere inspection and maintenance of the apparatus: “The first step toward effective maintenance work is knowing the risks that go with the rides. To this end we take a thorough look at each amusement ride and can then work with technicians and operators to reveal weaknesses that might not be picked up on in normal maintenance,” says Mr Bakker. There are two types of risk analysis: “The design risk analysis takes place during the construction of the ride, we review and approve it. For us it’s the operational risk analysis which matters. This is performed for the first time during commissioning and is then regularly updated.”

Safety at Toverland

Safety at Toverland Since 2005, TÜV Nederland has been the first point of contact for risk assessment in the Toverland amusement park near Venlo. Since 2007, one of the main attractions in the park has been the wooden roller coaster “Troy”. Rising up to a height of 33.5 metres and at 1,040 metres in length, it is the largest of its kind in the Benelux countries. The construction features 2,500 cubic metres of timber, 90,000 bolts and a full sea container’s worth of nails. Two trains, each of which weighs eight tonnes, negotiate the numerous bends at high speed – on a track which is, moreover, inclined over its entire length. “With a such a complex ride, constant safety reviews have top priority,” says Ruud Veugelers, who runs the technical department at Toverland.

Precisely tailored software

The risk analysis was significantly simplified last year thanks to new software. This was developed by Michel Harinck. The engineer worked at TÜV Nederland as a jobbing student and made software-supported risk analysis the theme of his dissertation. “What they had previously used was a system from the offshore industry which could also be applied to rides and a documentation tool that had way more functions than we actually needed. Simpler implementation needed customised software.”

For the development of an application tailored to amusement parks, Harinck tested several risk identification and assessment methods, some of the features of which were incorporated into the new software. “In the accompanying manual we explain the 13-step structure in which risks associated with rides are identified, assessed and evaluated. This gives us a clear structure for all rides – and a readily comprehensible, easy-to-use system,” says Harinck. This is great news for Toverland – and, last but not least, for the visitors, who can now feel completely safe even on the most nerve-jangling of rides.
