Mobile onshore power plant

Denmark’s first mobile onshore power plant in the Port of Grenaa

The Port of Grenaa can as the first commercial and industrial port offer drilling rigs and ships low-cost and flexible power from a mobile onshore power plant.

The plant is further the biggest in a Danish commercial and industrial port, meaning that the port has the biggest mobile and stationary onshore power plants.

The new mobile onshore power plant offers the customers of the port financial benefits, since the power is significantly cheaper than the power produced by the ships and drilling rigs by means of their own diesel generators, says CEO of Port of Grenaa, Henrik Carstensen:
"Our customers do not only save diesel oil for the generators but also time, money and manpower for service and maintenance of the diesel generators. The connection to our onshore power plant is altogether a good deal for them. The power from the onshore power plant is further far more environmentally friendly than the power generated by the diesel generators aboard ships and drilling rigs.”


The plant can service several units simultaneously

The high capacity of the new onshore power plant in the Port of Grenaa makes it possible to service several units simultaneously, says Peter Castberg Knudsen, co-owner of PowerCon A/S, delivering the plant:
”It is not only the first mobile onshore power plant in a domestic commercial and industrial port - it can service two customers simultaneously and further accommodate individual requirements in terms of frequency and voltage. The output of 2,000kVA also makes the new onshore power plant the biggest in a commercial and industrial port."

All frequencies and voltages

Drilling rigs and ships require power of different frequencies and voltages - depending on their origin. The power in Denmark has a frequency of 50Hz and voltage of 400V, while drilling rigs and ships from other parts of the world typically need power with a frequency of 60Hz and voltage of 600V or 690V. With the new onshore power plant, the Port of Grenaa can supply all customers with power, regardless of their origin, since the plant is able to convert Danish power into power with the exact frequency and voltage that matches the specific requirements of the individual customer.

Upgraded stacking capacity

Henrik Carstensen underlines that the new onshore power plant is another upgrade of the capacity of the Port of Grenaa within stacking, since the offer for cheap onshore power first and foremost applies to drilling rigs and ships, stacked or maintained in the Port of Grenaa for longer periods. The plant is part of the strategy in terms of stacking:

"For the past few years, we have evolved within all seven core business areas - not least within stacking. We experienced a breakthrough in 2018, manifested by Maersk Drilling selecting the Port of Grenaa to conduct the extensive maintenance project on one of the world’s biggest drilling rigs, Maersk Inspirer. We have developed solid and strong positions when it comes to stacking and our new mobile onshore power plant is another strong argument for selecting the Port of Grenaa for renovation or stacking of drilling rigs and ships," Henrik Carstensen says and stresses that the upgrade with the new mobile plant is an addition to the Port of Grenaa already having the biggest stationary onshore power plant in a commercial and industrial port in Denmark.
