MAMMOET OPTS FOR ITS MSG80 CRANE OVER A GANTRY SYS­TEM TO ERECT COLUMNS AND RE­AC­TORS AT IN­DIAN RE­FIN­ERY

PMV Middle East - - PEAK PERFORMANCE -

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.
