The Port of Oslo has signed a contract with Norwegian yard Maritime Partner to build a patrol boat with hybrid propulsion. The vessel is due for delivery early 2021.
The new boat of type Alusafe 1300 MKIII Patrol Hybrid will be made of recyclable aluminium. It will be used for port surveillance as well as escorting of larger vessels sailing in the harbour. It will be among the most environmentally friendly of its type. The propulsion is done by twin water jets connected to the diesel and electric motors. The top speed exceeds 30 knots. Batteries can operate the boat at low speeds of 4 to 5 knots for 2 to 3 hours. The diesel engines use biodiesel, and emissions are in accordance with strict international environmental regulations. The hybrid technology reduces the use of diesel by about 70%. The boat will run on batteries at low speeds, sufficient for inspections in the port areas. When high speed is required, the clean-burning diesel engines can be used which simultaneously charges the batteries. The boat can also be charged directly from shore power.
