Highlight:
In Brunei we installed new exchangers at a plant, which is still in operation. There are four LNG trains and Mammoet derigged and rigged the crane each time to a new location – all in accordance with the procedures and restrictions imposed by working on a plant while it is in operation.The new heat exchangers arrived on an oceangoing vessel from Europe. The exchangers were offloaded by the vessel’s cranes onto a barge, which was fitted out with supports and load spreaders. After

the load had been lashed down a Ro-Ro operation was carried out. Once all the arrangements for the permits and the police escort were completed the exchangers were transported 30km along a pitch-dark road. Once the last exchanger has been installed we had a long break while the mechanical contractors tied in both new exchangers. During each coming shutdown in 2005 we will remove one old exchanger.
A powerful job in Taiwan Location Main equipment
Aodi, Taiwan MSG and Selfpropelled Conventional trailers
Highlight: The Taiwan Power Corporation decided to increase its nuclear power capabilities at Lungman by adding units 3 and 4. A subcontractor contacted Mammoet for transporting the so called RPV, which is a core element of the power units. In addition it was Mammoet’s job to hoist the RPV and position it on its foundations at a radius of 63 meters. Quite a challenge
if you consider the weight of no less than 850 tonnes. Mammoet applied its famous MSG here with 67 meters main boom and 2600 tonnes ballast. Before the configuration could be commissioned, local authorities and the customer had to qualify the equipment. The test was done with 28 containers filled with sand and simulated the real lift. The same containers were used to test the road for the platform trailers of our
customer. As work shifted to the actual job, the RPV came in horizontal position. Supported by a tailing frame of the RPVs manufacturer, Mammoet erected the RPV and safely delivered it exactly on where it was supposed to land. Next year, Mammoet will redo this job for the second RPV that already arrived at the site and is kept in temporary storage.

Skidding high Location United Arab Emirates Main equipment Trailers, ballast pumps, skidding and jacking equipment
Highlight:
A desalination plant has been erected at a powerplant in the United Arab Emirates. Six evaporator blocks were fabricated in India and transported to the United Arab Emirates. Mammoet Dubai was contracted to perform the load-in from the barge using semi selfpropelled hydraulic platform trailers as well as ballast pumps. Subsequently it was a very tight fit to get the evaporators adjacent to its foundations. After removing the trailer the evaporator (weighing 415 tonnes) had to be jacked up 5 meters using climbing jacks. At this height the Mammoet crew had to insert four rows of extra skidding beams to connect with the already prepared skidding beams towards the foundation. A total skidding distance of 40 meters was required (hence 160 meter of skidding beam built up at an elevation of 4.5 meters!). This has been surely one of the most challenging projects performed by Mammoet Dubai in 2004!

Something different Location Limbe, Cameroon Main equipment SPMTs, pontoon and auxiliary equipment.
Highlight:
In many countries it’s nothing less than a commodity: electricity, 24 hours a day. However, until recently they could not dream of anything like that in Cameroon. But a Finnish company has changed all that. It built a power station and contracted Mammoet for the transport of four electric motors and four generators. The electric motors generators were loaded on board of a vessel in The Netherlands and sailed to Cameroon. Once the ship arrived at the port, the cargo was unloaded and driven onto a pontoon. This all sounds very simple – but the port was not the final destination. Mammoet constructed a temporary quay to facilitate the load-out. The crew sunk the pontoon just off the beach. Then they laid containers, sandbags and dock boards around the pontoon so that two x 10 axle lines SPMT could drive the cargo to the beach. Then the crew constructed a new road from the beach to the ‘main road’. The motors and generators thus could proceed to the final destination. The Finnish company installed the equipment and now the local population has electric power 24 hours a day, even after a severe downpour or a storm – and Mammoet gained yet another interesting experience!
