For the first time, three of Mammoet’s largest cranes will be used at the same time to as part of an ambitious construction schedule for Petroliam Nasional Berhad (PETRONAS).
PETRONAS’ largest downstream investment in Malaysia is the Pengerang Integrated Complex (PIC). With an investment of US$27 billion, it covers an area of 2526 ha. in Pengerang, Johor.
The PIC consists of the refinery and petrochemical integrated development (RAPID), which is supported by its Associated Facilities forms part of the Pengerang Integrated Petroleum Complex (PIPC). This project supports the government’s Economic Transformation Programme which will be operational by 2019. With the production goal of 300 000 bpd, the refinery and petrochemical plants are designed to produce premium differentiated and specialty petrochemicals.
In order for PETRONAS to achieve its ambitious target of becoming operational by 2019, it is necessary to work on multiple phases of the construction simultaneously. Since 2016, Mammoet professionals and up to 35 cranes have been engaged on site. This involved the installation of heavy columns, the largest of which is 1809 t and 121 m high.
To be able to lift and install the columns, high capacity cranes are necessary and, given the ambitious schedule, some need to work in parallel. Therefore, Mammoet has mobilised three of its biggest cranes from its global fleet to Malaysia – the PT 50 (Mammoet - PT 50) , PTC 35 (Mammoet - PTC 35) and PTC 140 (Mammoet - PTC 140) ring cranes.
PTCs are built on a ring track instead of crawlers. They have been specifically designed to combine a wide reach and high capacity on a small footprint. The ability to turn 360 degrees brings a combination of agility, flexibility and sheer lifting power. This is the first time in history that three of Mammoet’s PTC type cranes are operating on one site at the same time. Together they offer a capacity of 10 000 t.
