South East Asia projects round up

Johor Bahru, Malaysia

Mammoet has moved a 1,800t 121m propylene fractionator, recognised recently as the country’s tallest and heaviest process column, for Petronas’s Pengerang Integrated Complex. Mammoet is providing the majority of the heavy lifting and transport of oversized and heavy components for this $26m project. Recently, Mammoet opened a new yard close to the project site which enables quick mobilisation and optimisation of transport and lifting schedules. To date, Mammoet has moved nine heavy vessels and columns for the steam cracker facility from the material off-loading facility Tanjung Setapa to the laydown area.

Xayaburi, Laos

Thai construction firm CH. Karnchang is using 23 Potain tower cranes from S.B.Siam to build the 820m long, 150m wide, and 35m high Xayaburi dam, which will generate 7,400GWh a year for customers in Laos and Thailand. The cranes include two MD 1600 cranes, able to lift 64t and configured with 80m jibs, as well as 21 other cranes built at Manitowoc’s Zhangjiagang plant in China.

Singapore

Tunnel engineering specialists Yu Sin Engineering used a Hydra-Slide HT300 skid system, fitted with specially designed skid shoe extensions, to move a tunnel boring machine 66ft into a tunnel. The parts were lowered 30m into the shaft using a Terex AC 700 from Hiap Tong. The boring machine comprised six parts, totalling 240t, with the largest piece a bearing weighing 98t. Yu Sin had found the 10,500kg weight skid system online, and arranged for it to be flown from the manufacturer in Canada in order to hit project deadlines. Hydra-Slide director of operations Robert Young also flew out to provide training on setting up and operating the system.

Singapore

Huationg Inland Transport used 16 axle lines of self-propelled Scheuerle- Kamag K25 H SP and non-driven K 25 H transporters to move the 41m-long 125t HISYAM 6 800m from the dry dock of specialist boat builder Sam Aluminium to the water’s edge, where it was then lifted into the water using two all terrain cranes. The vessel is now being used to shuttle workers between to offshore facilities in the Straits of Malacca.

Vinh Tân, Vietnam

Sarens used its modular gantry system to install two 6m high 350t generator stators for the $1.4bn 1,200MW Vinh Tân 4 power station, in Bình Thuân province, Vietnam, currently being built by Mitsubishi Corporation and Doosan Heavy Industries for Electricity of Vietnam. The containerised gantry system was shipped from Malaysia, and then set up with its 16m high support structure over a total time of 10 days, to a tolerance of +/-5mm. The stators were then raised 16m to their operating height and skidded 40m into the building.
