Mammoet installs items for petrochemical plant expansion

Mammoet was hired by Toyo Engineering Korea on behalf of Bangkok Synthetics (the owner of the plant) to transport and install 24 items as part of the owner’s project to expand their petrochemical production plant. The items included nine long towers with lengths up to 74 m and weighing up to 213 t. All items needed to be transported from a port to the plant located at Map Ta Phut Industrial Estate and installed onto foundations.

The normal commercial port to receive heavy and oversized cargos is located 5 km from the construction site. Transport of heavy/oversized cargos from this port is only allowed on Saturday and Sunday and it would also require to make three 90° turns, which would prove to be a challenge with regards to road safety and obstacles costs. As such, Mammoet reviewed the area and recommended the client to use the Maptaphut Industrial Terminal (MIT) port instead. Mammoet had to demonstrate to the local authorities the advantages of using MIT port in order to get special approval for this port. This in fact resulted in a more efficient route reducing road safety challenges and required modifications to existing infrastructure. Furthermore, the Maptaphut Industrial Terminal (MIT) port is located only 1 km from the BST site, cutting the time required for the transportation in half. Transport from this port was also allowed on any day of the week and this was a major time saving to the client because installation of the columns could be done on a daily basis.

Next, Mammoet assisted Toyo Engineering Korea with the installation of the towers using the PTC 35DS crane (a 1600 t capacity ring crane). This crane was chosen because of its large lifting capacity at greater radius from one lifting position. The alternative was to split the towers into two parts and lift them using a crawler crane which would be costly in ground preparation and welding works. The advantages of using a ring crane were time and cost saving for the client.

The combination of using one company for the transportation and installation was an added value for the client because Mammoet was able to look at an overall solution to ultimately save time, costs and reduce road safety challenges and work at site.
