which sat outside the building,” explains Marr. “The site became congested and confused. Service infrastructure such as power or water couldn’t be installed because cranes were sitting in the way.

“In contrast, we worked closely with a client on a recent project, who adopted our craneage philosophy, and its project was completed in half the time of the other build. “Now that client has become the partner builder for a data centre
Great green giant ring crane
Sarens’ SGC-90 electric crane, the newest and greenest addition to the company’s fl eet of giant cranes, has lifted two regenerators, each weighing over 1000 tonnes at the Balikpapan refi nery project in East Kalimantan, on the island of Borneo, Indonesia. The lifts were performed for the RDMP Balikpapan Joint Operation as part of the Indonesian government’s Refi nery Development Master Plan (RDMP), which aims to expand and upgrade fi ve refi neries and increase production by 150%. The site provided adequate space for assembling the ring crane
so it could perform lifts from two different positions. All project equipment was transported via sea from the UK and
Bahrain and was en route for approximately six weeks from each location. While the other cranes have been on-site since late 2020, the SGC-90 is the latest arrival, and rigging it took approximately 30 days. The SGC-90 lifted a propane/propylene splitter a height of over
110 metres and weighed over 750 tonnes. It was easily the longest load to be installed at the site, and even as the SGC-90 utilised 130 metres of main boom, it was still a very tight boom clearance. A special spreader beam was designed for this particular lift, which also required the SGC-90 to hold the lifting points as a tailing crane crawled about 90 metres. Once the load was vertical, the SGC-90 slewed it clockwise onto its foundation. A total of 21 personnel were involved in this complex heavy lifting operation.
provider, and every data centre they build is being completed faster. The last one was completed in just 35 weeks, using our cranes.” So it seems that the future of modular construction, with fewer but heavier loads, is bringing economies of cost and of time.
