ECONOWIND WINS FIRST FLEET ORDER Schottel propels research vessel
Econowind’s wind-assist VentiFoil units will be retrofi tted on two of Dutch shipping company Vertom’s cargo vessels.
MV Progress and MV Perfect will be installed with the VentiFoils by the end of 2022 in what will be the first fleet order for Econowind, which says it has upgraded the suction method on the units with the result that there are fewer moving parts.
Vertom made the decision to invest in the VentiFoil after considering key environmental factors including the Carbon Intensity Index for shipping and emissions per cargo, it says.
VentiFoil systems are wing-shaped units that can fold and rotate around their own axes with the ability to be reefed. They can now be installed directly onto the vessel rather than remain inside containers.
Smart suction is integrated in the wing, resulting in double the force, Econowind says. The shape has been designed using modern aerodynamic theory, creating high propelling force relative to size.
“Installing the VentiFoils is a big step forward in reducing (CO2) emissions and fuel consumption for our current fleet. It is, along with our upcoming newbuilding program, a good step towards reducing our carbon footprint,” said Rolf van Leeuwen, Senior Technical Superintendent at Vertom.
8 Container-based VentiFoils
Germany’s most modern research vessel has been equipped with a Schottel propulsion system.
The survey, wreck search and research vessel Atair has on board a Schottel PumpJet, a TranverseThruster type STT 170 (200 kW) in the stern and a TranvserseThruster type STT 1 (330 kW) in the bow.
Schottel’s TransverseThrusters have elastically mounted well installation, which is said to give greater comfort, reducing sound emissions by up to 11 dB. The soundoptimised STT helps to minimise underwater noise, resulting in a low-vibration design suitable for vessels of all types and sizes and especially for service operation vessels.

CASTOLDI OFFERS WATERJETS FOR LARGER VESSELS
Castoldi has launched a new waterjet, which it says is a game changer for larger vessels ich it says is a game changer for larger vessels
The Turbodrive 600 H.C.T. is the largest waterjet in the Castoldi range to date, equipped, like the other models of the range, with an integrated gearbox (certifi ed for heavy duty ratings) and hydraulic clutch.
“Our aim is to supply the customer with not only the waterjet but a complete package that incorporates the propulsion with integrated gearbox and clutch, a dedicated control system to manage also the engine and eventually the interceptor integration, directly installed on the waterjet unit,” said Giacomo Castoldi, Owner, Castoldi Yachts.
“From a technical point of view, especially on large vessels, our integrated gearbox represents a unique advantage that allows it to create compact installations with considerable savings on space, weight and cost.”
Key features
Castoldi’s waterjet is equipped with oil lubricated bearings, impeller shaft protected within a housing and the advanced patented Clear-Duct unclogging system, which back-flushes the intake while opening the protection grid.
It has been created after four years of advanced CAD and CFD studies, a complete and easy-to-install propulsion system that allows compact applications and considerable savings in dimension, weight and cost. The steering and reversing actuators have been designed with one hydraulic cylinder dedicated to the steering nozzle and two hydraulic cylinders controlling the movement of the reversing bucket, which allows for rapid and efficient crash-stops in all operating conditions.
The waterjet is made from high quality material with a Duplex micro-cast stainless steel impeller and titanium liner. It has been toughened using an anti-corrosion hard anodising treatment protecting the aluminium alloy components and cathodic protection by sacrificial anodes. This makes the waterjet unique in its construction quality.
The Turbodrive 600 H.C.T. is controlled by the ACES electronic system that can be supplied with several extra features such as position keeping, smart anchor, unmanned interface, autopilot integration and hybrid power.
“When we entered this market, 25 years ago, most of the tenders were equipped with stern drives or outboards and there were very few companies manufacturing waterjet driven tenders,” said Giacomo Castoldi. “Now most tenders are equipped with waterjet drives and this propulsion system is well known and appreciated by crew and owners.”

Propulsion systems secured for green SOV
Azimuth propulsion and manoeuvring have been ordered for the world’s fi rst ‘green’ SOV.
Norwegian propulsion and manoeuvring systems firm Brunvoll will supply its technology to new Service Operation Vessels (SOV) belonging to Esvagt, the Danish shipping firm that owns what is being touted as the world’s first SOV to operate on green fuels.
Brunvoll will supply propulsion azimuth thrusters, retractable azimuth thrusters, tunnel thruster and BruCon condition monitoring system to the vessel, which will be powered by Ørsted supplied renewable e-methanol, produced from wind energy and biogenic carbon, and batteries.The HAV Design 833 SOV is being built at Cemre shipyard in Turkey.
“This is a breakthrough for Brunvoll in the azimuth thruster propulsion market. Esvagt and HAV Design are both important players in the renewable segment. We have a long relationship with both, and we are excited that they now also will use our propulsion thrusters,” said Sales Manager Bernt Rune Riksfjord. “We look forward to putting our propulsion thrusters to the test on this advanced vessel.“
The vessel will be equipped with Brunvoll’s new Condition Monitoring System (CMS), a layer-based platform with extensive cyber security improvements. CMS provides advanced monitoring of thruster and propulsion systems and includes hardware and various algorithms for detecting concrete events and operational characteristics to optimise maintenance and operations.
Danfoss Power Solutions’ Editron division is partnering for a sixth time with Baltic Workboats to supply the electric propulsion system for a new hybrid passenger and bicycle ferry.
The Ferry 19 Electric, the design of which is based on the earlier Ferry 22 Electric, will be delivered in 2023 to DAB Vloot, the Flemish governmental fleet operator.
“The versatility of our EDITRON system means we can provide fully electric and hybrid solutions for any kind of ferry,” commented Atte Yrjölä, sales manager at Danfoss’ Editron division.
“Our marine system is robust yet lightweight, plus delivers high efficiencies. Our equipment is also really compact, crucial when building small hybrid vessels.”
The ferry will be capable of transporting up to 50 passengers and 25 bicycles in emission-free operation using the fully electric mode. A Corvus Orca Energy battery pack which is charged during operation provides an additional source of propulsion power. Solar panels on the roof of the ferry will cover auxiliary power consumption.
Hybrid system
Editron will also equip the vessel with an additional diesel-powered engine to support the electric propulsion. While in operation, the Ferry 19 will save approximately 90-100 kilograms of CO2 per day compared to a traditional diesel-powered vessel.
The vessel’s battery and electric propulsion system is integrated into Baltic Workboats’ integrated automation, monitoring and control system. Shore-charging will be courtesy of an automatic system developed in-house by Baltic Workboats.
