Dutch firm Hull Vane BV has received an order for six hull vanes from Damen Shipyards for a series of police patrol vessels ordered by the Dutch National Police
Damen has delivered two vessels in the series – a 20-m vessel intended for inland waterways (Stan Patrol 2005) and a 25-m seagoing vessel (Stan Patrol 2506) which will operate in coastal waters. Hull vanes were used successfully on both vessels and as a result Hull Vanes said Damen has placed an order for four more units to complete the series of vessels, with the remainder set for delivery during 2020 and 2021.
The hull vane has been introduced on both vessel sizes to make the vessels more hydrodynamic, helping to cut through the water and reduce fuel consumption.
The hull vane is a fixed foil that is located beneath the vessels’ stern, reducing fuel consumption by optimising waterflow around the aft of the vessel.
Damen has also added other measures in the vessels with the aim of reducing emissions including a lightweight composite superstructure and an exhaust gas after treatment system.
Hull Vane sales director Bruno Bouckaert said “We are very pleased to count Damen Shipyards among our repeat customers. From the 28 hull vanes built so far, eight have been installed on patrol vessels and another six are on order for other patrol vessels. Making less waves means less energy is needed to propel these vessels.”
The hull vane’s hydrodynamic wing-shape converts the energy of the stern wave and of the ship’s motion through the water into forward thrust. In addition to patrol vessels, the device can be used on superyachts, naval ships, fast supply vessels and passenger ships.
Hull Vane is operating as an independent sister company of Dutch Naval architect firm Van Oossanen.
Damen is also building two fire-fighting vessels for Hamburg Port Authority.
