Five generator sets from Dresser-Rand are to power Europe’s largest caisson-building floating dock, the Kugira II in Setúbal, Portugal.
The genset suite consists of four Guascor SF180TA units rated at 400kW (500kVA) and a smaller 76kW (95kVA) unit.
Each of the floating dock’s towers is equipped with four control centres that operate all of the dock’s processes. The control centres allow the generator sets to operate 365 days per year and feature an electronic injection pump, a wet exhaust manifold, a double-step intercooler and an oil cooler in an auxiliary circuit.
The double cooling system maintains two independent cooling circuits with a high temperature of 80 degrees C for the cylinder heads and a low temperature of 30 degrees C for the oil cooler and aftercooler. The double cooling system comes with or without the option of an oxidation exhaust catalyst.
These features allow for easy operation and maintenance and the ability to supply power in off-grid areas, Dresser-Rand said, as well as providing a heavy-duty, continuous energy source for nonstop maneuvering.
The dock was built by Spanish infrastructure development firm Acciona in 2012.
