MAMMOET OPTS FOR ITS MSG80 CRANE OVER A GANTRY SYSTEM TO ERECT COLUMNS AND REACTORS AT INDIAN REFINERY
Mammoet has won a new contract with L&T Hydrocarbon Engineering Limited (LTHE) to provide heavy lift works on the Visakh Refinery Modernization Project (VRMP) in India from March
2019. This large expansion on the existing Visakh Refinery began in early 2017, and will increase the refinery’s production in order to produce and distribute Bharat Stage VI fuels to meet a new emission standard, due for implementation in India from 2020. Mammoet is scheduled to deploy a MSG80 crane to erect columns and reactors, the heaviest of which is a 50-meter reactor weighing in at 1650 metric tons.
The initial plan was to utilize a gantry system for the lifts. However, Mammoet proposed the MSG80 as a more efficient solution. With its 3200MT lift capacity, the MSG80 can move much faster than the gantry system, while minimizing impact on construction in progress.
This is because it has the ability to lift several items from a single position, due to its height and reach. A gantry would need to be erected to complete the lift, then dismantled, relocated and rebuilt for the next lift. In addition, unlike a gantry system, the MSG80 does not need a concrete foundation, which can be costly and time-consuming to construct. A total of five lifts of up to 1650 metric tons are scheduled for the project: a vacuum column, a crude column, two reactors and a heavy fractionator. The MSG80 will execute the lifts from three different locations.
