Danish composites specialist Tuco Marine has delivered a 15-metre high-pressure cleaning boat to Norwegian aquaculture services company Akva Marine.
High-pressure cleaning of aquaculture pens and their associated equipment is a complex task and so a specialist craft was needed to for the task. Klara 1 is built from composite materials with the hull being made from E-glass over a PVC core and the superstructure being carbon fibre over a PVC core.
The decision to construct the vessel from composite materials was made due to the reduced structural weight of the vessel and the low maintenance and superior durability that composites offer compared to metals.
Klara 1 is equipped with two Volvo Penta IPS units for propulsion. Each diesel engine is paired with a forward-facing, counter-rotating set of propellers that offers increased fuel efficiency and allows for higher speeds to be attained with lower power. In addition to drastically simplifying vessel movement, especially at low speeds, the IPS system gives Klara 1 a top speed in excess of 33 knots.
The hull structure for this particular vessel features special appendages and reinforcements that make it ideal for fish farm operations. The design provides for a stable ride, even in rough seas, with fast operations in rough seas limited only by the human cargo.
The aft working deck is open with plenty of space for water pumps and high pressure hoses. A Guerra Marine hydraulic deck crane is installed at the stern and is rated to lift 765kg at 7.2 metres, more than sufficient to deploy inspection ROVs as well as loading and unloading specialist equipment.
The wheelhouse features forward facing helm seats for two crew as well as bench seat, with a dining table, for an additional two. The helm station itself is fitted with a large screen plotter, which is connected to a Simrad radar. Located separately within the superstructure is a toilet and small workshop.
