Pump Ship construct ashore
The project water intake is located in S. Lematang river, the
initial scheme for water intake is planed to contruct water pumping
station,with totally three pumps, one spare, two occupy.
As the local rainy season as long as up to
6 months, but construction for water pump station need at least two
dry seasons to complete. As Rainy season come, the level of river
water keep raising, the previews cofferdam construction and other
construction work will be fully flooded, including the foundation.
Also there is no such qualified contractor to do this job in
indonesia, with all these conditions, we get the ideal of water
pump ship replace water intake station, as it is constructed
ashore. when finished, move to river, the ship up and down as water
level, so that through the application of new technologies to solve
construction problems.
