Torqeedo Deep Blue powered raft on Colorado River

Colorado River Discovery is going to mark the 100th anniversary of the National Park Service by introducing a new, completely electric raft used to travel down the Colorado River.

Colorado River Discovery, a group that takes tourists on trips down the Colorado River, has been working on the raft for 10 years. The raft is named Helios, in homage to the God of the Sun in Greek mythology.

“A company called Torqeedo, which is based in Germany, developed an incredibly efficient, 100-percent electric outboard motor that we have put on this raft,” Korey Seyler, general manager at Colorado River Discovery, said.

Seyler said the raft will not produce any emissions and will run from power from a charging station at Glen Canyon Dam.

“It’s actually produced by hydroelectric power that charges this, so that’s what brings the zero emissions out,” he said.

The company has been setting aside money since 2006 to pay for the raft, Seyler said.

“We’ve actually set aside $1.50 for each guest we take down the river over the past 10 years in order to help with the research, development, and manufacturing of this raft,” he said.

Seyler said customers can start riding the raft this spring after its official launch on Earth Day, Apr. 22.

Hapag-Lloyd equips Zodiacs with Torqeedo Deep Blue electric motors

Hapag-Lloyd Cruises has become the first cruise operator to install eco-friendly electric motors onboard the rubber Zodiac boats on its expedition vessels, Hanseatic and Bremen.

Used to take guests to inaccessible areas in some of the world’s most remote regions, the Zodiacs have been equipped with Deep Blue electric motors from German manufacturer Torqeedo. The 80 horsepower motors have been piloted over the past year and showed a ‘previously unseen level of output’.

Unlike combustion motors, the Deep Blue electric propulsion system does not release emissions or harmful substances into the water, helping to protect the vulnerable waters Hapag-Lloyd’s excursions visit. In addition, the motors are ‘considerably quieter’ than the Zodiacs’ previous 36 horsepower motors.

“For years, Hapag-Lloyd Cruises’ ships have used low-emissions marine diesel in fragile cruising areas such as the Arctic and Antarctic, and equipping our expedition Zodiacs with electric motors represents another investment in the future of our environment,” said Karl Pojer, CEO of Hapag-Lloyd Cruises. “With their flora and fauna, our cruise destinations are key to the appeal of our itineraries and we want to protect what fascinates us.”

Torqeedo Deep Blue 80 pushes 60 metric tons

Torqeedo’s high-voltage motor in the commercial environment
In the field of physics, work is said to occur when a force that is applied to an object causes a displacement of that object in the direction of the force. Going off this definition, the high-power Deep Blue 80 electric motor is a true workhorse.

A workboat equipped with a Deep Blue is used to maneuver barges on the quarry lake Rogau near Frankfurt. Considering that these barges consistently carry over 60 metric tons of gravel, this application impressively demonstrates the unparalleled performance of the high-voltage electric motor.

Pushing tremendous loads
In order to protect the local groundwater, the gravel quarry Kaspar Weiss decided to equip their workboat with the zero-emissions Deep Blue system. At their Rogau location the quarry yields countless tons of gravel annually. However, this commercial extraction of gravel results in vast amounts of useless byproducts such as sand, mud, clay, and rocks. With the help of a workboat and barge, these byproducts are removed. The Deep Blue powered workboat locks onto the barge to maneuver the 60 tons of unwanted material to the dumping location. In this way the Deep Blue helps remove over 700 tons of material from the Rogau quarry lake each day.

Traits for success
Developed by Torqeedo, the high-power Deep Blue propulsion system is well suited to applications involving heavy loads. Fed with 65 kW of electrical energy, the Deep Blue system achieves a propulsive power equivalent to an 80hp petrol outboard, making it the world’s most powerful electric outboard operating at an efficiency of 54%. As a result, the Deep Blue achieves a static thrust of up to half a ton, which represents performances that were previously unheard of in this category. It is precisely these performance characteristics that allow the Deep Blue to be successful in the quarry application, as a large propeller is need to generate the thrust necessary to move the 60 ton barge. Thanks only to the high torque of the Deep Blue is it possible to use an appropriately large propeller.

Power and endurance
The necessary electricity for the Deep Blue is provided by lithium batteries, which store a total of 26kWh of electrical energy. The batteries make use of the latest advancements in automotive lithium battery technology and are adapted to the marine environment. Torqeedo, the global market leader for electric marine propulsion systems, provides a nine year capacity warranty for its batteries. This warranty promises that after nine years of daily use the batteries will still have a capacity in excess of 80% of the original capacity.

The quarry-lake Rodgau is not the only site of commercial use for the Deep Blue. The high-performance system is also employed as a propulsion solution for water-taxis, ferries, patrol boats, and excursion boats.

Deep Blue 80 electric outboards for Ophart workboats

A German company has developed a new approach to building workboats. Instead of doing the whole of the construction in a boat yard, Ophart Maritim builds a range of hulls in aluminium and supplies these to owners or other shipyards for completion and fitting out.

The Opship hulls are supplied as the basic open hull, what the company calls a Boat Chassis, which gives the recipients a proven design on which to develop their own ideas for the completed vessel.

The aluminium hulls are designed in three sizes and they are all based on a unique hull design that features a moderate vee hull with wide chines for easy planing. There is a deep narrow forefoot to improve the low speed handling and a flare in the bow to provide a dry ride.

The hulls are primarily designed to accommodate outboard power with up to triple 300 hp outboards on the largest of the hulls to give high speeds. To fit these power units a bolt-on module is attached to the transom. Fuel tanks can be specified if required. Alternatively the hulls can be specified for electric propulsion using the range of Deep Blue 80 electric outboards produced by Torqeedo and with a battery pack to offer range of over 50 miles at low speeds but with the larger electric outboards, a speed of 12 knots can be achieved but with a more limited range.

The aluminium hulls are fully welded using 8 mm plating and fitted with closely spaced transverse framing. This framing is both welded and glued in place, the glue creating a form of insulation that is designed to reduce the sound. An interior deck can be supplied over the frames or these can be left exposed for the final builder to complete as required.

The concept of the hulls developed by Ophart Maritim is to offer an advanced and tried and tested hull concept at an attractive price. These hulls are designed to meet the demands for a wide variety of workboat roles from fast patrol boats to rugged harbour workboats. They are currently produced in sizes from 8 metres up to 12 metres and one of the main advantages is the quick delivery time. Also by focussing on just producing hulls in aluminium Ophart is able to invest in advanced construction techniques.
