Aertssen-5

Reactor aloft

In the first half of 2015, Aertssen Kranen secured a new hoisting contract with BP Chembel. In addition to the hoisting and final alignment of the reactors, the contract also included preparatory work activities and rough and definitive detailed engineering. The beginning of August was the moment to place the most crucial item in the entire contract: a reactor of at least 420 tons with a diameter of 10.12 m and nearly 18 m in length.

In the first half of 2015, Aertssen Kranen secured a new hoisting contract with BP Chembel. In addition to the hoisting and final alignment of the reactors, the contract also included preparatory work activities and rough and definitive detailed engineering. The beginning of August was the moment to place the most crucial item in the entire contract: a reactor of at least 420 tons with a diameter of 10.12 m and nearly 18 m in length.

Over the E313 and Nete
First the gigantic reactor had to get there. Our affiliate company Roll-iT took charge of moving this reactor to BP Chembel. For this, it mobilised 32 SPMT axle lines for a night-time transport over the E313 highway. The police stopped traffic and the guardrails were removed temporarily in order to ensure rapid passage with full safety. However, the next obstacle quickly arose: a bit further on was the bridge over the Nete, which was unable to handle the weight of the transport. Naturally, this had been factored in beforehand, and a temporary bridge was constructed over the existing bridge. In this manner, the reactor made its way to its location safely.

Pivoting and hoisting
Upon arrival at the site, two crawler cranes stood ready to lift the reactor. This involved a Terex CC2800-1, which was deployed as the main crane, and a Terex CC2400 used as the starting crane. This cranes have a maximum capacity of 600 tons and 400 tons. Once the reactor was turned upright, it was placed on its final foundation with a radius of 15.5 m.

Smooth course of progress
This concerned a large-scale job that nonetheless progressed quickly. As Bob De Jong, Project Manager at BP Chembel also noted: “The removal from the E313 crossing to the BP grounds lasted just 90 minutes – even more quickly than was estimated. The temporary bridge over the Nete was completed just in time. The hoisting also went perfectly: the reactor was properly positioned and the hoisting itself went just as smoothly. Naturally, we are very pleased with this.”

In October, a second, lighter reactor was successfully removed for adaptation work. Later – during the following phase of the project – it will be built back into the BP factory.
