Damen delivers their first hybrid patrol vessel to Amsterdam               

The first hybrid vessel developed by Damen Shipyards Hardinxveld, has now been delivered to Waternet (the Water Network Foundation) in Amsterdam. 

Waternet is taking a leading role in reducing emissions from vessels within the municipality of Amsterdam as part of the city’s Air Quality Action Plan. The Waterspreeuw which means “Dipper” in English will be used for inspections, patrols and for enforcing various legislation and rules in Amsterdam’s canals and other waters.

The hybrid vessel can be powered entirely by electricity with a 130 kW electrically driven rudder propeller manufactured by Hydrosta. ESTechnology supplied 13 lithium polymer batteries for the drive system, providing enough electric power for at least 6 hours at an average cruising speed of 10 km/h. The Steyr/AMK diesel generator set complies with the European CCR3 standard for exhaust gas emissions set by the Central Commission for the Navigation of the Rhine. This means that the engine easily complies with the CCR2 standard stipulated by the client.

The engine switches on automatically when the battery capacity falls below the minimum level. Using both drive systems, the Waterspreeuw has a top speed of 16 km/h; using the batteries alone, it can hold that top speed for an hour (6 hours at cruising speed). The engine provides additional capacity when necessary. However, the intention is for the vessel to operate on electric power.

The Waterspreeuw’s designers at Damen´s yard in Hardinxveld took account of the various different waters and bridges in and around Amsterdam. With its overall height of 1.80 metres, it can basically pass under all the bridges along the city’s sailing routes. The special hull design makes it a low-wash vessel, thus minimising inconvenience to houseboats during manoeuvres in Amsterdam’s busy canals. The rudder propeller and the 11 kW bow thruster ensure that it is highly manoeuvrable in the narrow canals. The new vessel has its own 3-metre spud pole, meaning that its can moor anywhere without being dependent on the mooring facilities available.  Darko Kapelina believes that a six hour range is just the start.
