The items included nine long towers length up to 74m long and weighing up to 213 tonnes. All items were 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 oversize cargos is located five kilometres from the construction site. Transport of heavy/oversize cargos from this port is only allowed on Saturday and Sunday and it would also require to make three 90-degree turns, which would prove to be a challenge with regards to road safety and obstacles costs.
As such, Mammoet reviewed the area and recommended 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 MIT port is located only one kilometre from BST site, cutting half the time required for the transportation. Transport from this port was also allowed at 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 installation of towers using the PTC 35DS crane (1600t capacity Ring Crane). This crane was chosen because of its large lifting capacity at greater radius from one lifting position. Other alternative was to split the towers in two parts and lift them using a crawler crane, which would be costly in ground preparation and welding works. The advantages of using Mammoet Ring Crane were time and cost saving for the client.The combination of using Mammoet 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.
