At a height of about 30 meters, the rope access technicians replace a heating tape and the associated insulation on a pipeline. To get to the site, they abseil down from the top platform of a column at a height of 30 meters and carry out the work secured by the rope. Compared to erecting scaffolding, the Bilfinger team thus implements the maintenance in a very short time and with a significant cost saving for the customer.
“With the rope access and positioning technique work methods, our climbers carry out the maintenance work for our client in a very time- and cost-efficient manner and in accordance with the highest occupational safety standards. In fact, rope access is a very safe way to perform work at such a height. After all, erecting scaffolding for this particular project would take about 20 times as long as access by rope. The rapid implementation also significantly reduces the potential risk to adjacent areas.”
— Christian Grauert, Project Manager Access Technology
In the process, the company can look back on a good safety record: since 2012, there has not been a lost-time accident during work at the refinery, where an average of more than 100 employees are on duty. Over two million hours of work have been safely completed by the team on site without an accident.
This is the first time that Bilfinger has used rope access and positioning technology at this refinery. The industrial services provider has already been carrying out industrial scaffolding and corrosion protection work there since 2010.
In the most recent contract extension, the Group and the customer agreed for the first time on alternative access in addition to scaffolding. Work using rope access and positioning technology and the use of lifting platforms were contractually provided for in addition to the main scaffold erection work in order to exploit the advantages of these techniques: very fast implementation of the work at low cost and effort with guaranteed quality of execution and high safety. This is because the rope access and positioning technology experts are commercial specialists with vocational training in the trades, such as metalworkers, locksmiths, plumbers or insulators. In addition, they have a special qualification as rope access and positioning technicians, also known as “industrial climbers”.
In a new building in Herne, the company will set up its own training center for this purpose due to increasing customer demand for the flexible and efficient rope access and positioning technology. The aim is to train further colleagues before the end of 2021, e.g. insulation specialists.
In a training course of up to 270 days, depending on the level of qualification, the industrial climbers will be specially trained for use “on the rope” and certified according to recognized standards, such as the specifications of FISAT (Fach- und Interessenverband für roilunterstützte Arbeitstechniken e.V.). The team also includes colleagues with qualifications according to the international IRATA standard and the standard for workers at height according to Information 212–001 of the German Social Accident Insurance (DGUV).
Bilfinger arnholdt looks back on a company history of more than 115 years and is one of Germany’s leading industrial scaffolding service providers. Specializing in industrial and specialty scaffolding, the company employs over 1,000 people at its headquarters in Oberhausen and its seven other branches in Germany. On the site of the large refinery, Bilfinger arnholdt is the sole industrial scaffolding partner for maintenance and modernization work as well as the execution of conversion and expansion measures.
The company also uses rope-secured industrial climbers in other countries, for example in the UK for the maintenance of offshore oil platforms or in Belgium and the Netherlands on industrial plants.
