Jensen Maritime to design Baydelta’s first hybrid tractor tug; Rolls-Royce technology


Jensen Maritime, Crowley Maritime Corp.’s Seattle-based naval architecture and marine engineering firm, was recently selected to provide the design for Baydelta Maritime’s new 100-foot, Z-Drive (azimuth thruster) hybrid tugboat. It will use Rolls-Royce hybrid technology and represents the first installation of a hybrid system for Nichols Brothers Boat Builders (NBBB), and the first hybrid tug designed by Jensen to enter the construction phase.

Scheduled for delivery in the first quarter of 2019, the tug will feature the same ship assist and tanker escort capabilities of existing Valor class harbor tugs, but with multiple operational modes. The Rolls-Royce hybrid system allows for the vessel to operate direct-diesel, diesel-electric or fully-electric while assisting the large containerships and tankers that operate in US West Coast ports.
This concept will save fuel and reduce emissions, while supplying Baydelta with the same power and vessel characteristics needed for their operations. The flexibility provided by the drive system will allow loitering and transit at up to 7-8 knots in electric-only mode, then a bollard pull of 90, or nine short tons, in combined diesel-electric mode.
The tug will be powered by two Caterpillar C3516 C Tier 3 diesel engines, each rated at 1995 kW at 1,600 rpm, supplied by Peterson Power of Portland, Ore.; and by two Rolls-Royce supplied 424 kW electric motors.The Z-drive system, two Rolls-Royce 255FP units, can accept power from the diesel engines, electric motors and from both power sources.
The electric motors are powered by three CAT C9.3 generators with 300 kW each, which are 480V three-phase at 1,800 rpm, and one harbor generator, a C7.1 150 kW 480V, three-phase at 1,800 rpm. All four generators will be supplied by Peterson Power.
The tug will have eight berths, and the major equipment on board will include a Rapp Marine electric hawser winch and a single drum tow winch. The tug is designed to carry up to 71,000 gallons of fuel and 4,300 gallons of fresh water. It will have a large pilot house providing all-around visibility; a deckhouse with an open feel; a large mess and lounge area; and accommodations for an eight-person crew.
The tugboat will be ABS Load Line classed and compliant with US Coast Guard regulations, as required at delivery.

Wärtsilä HYTug Meets Environmental Demands for New Brazilian Port



The technology group Wärtsilä has signed a memorandum of understanding (MoU) with Petrocity, the parent company of the new port facility being built in the Brazilian city of São Mateus-ES, to develop a harbour tug design. The prime consideration is to maximise the ecological operational sustainability of the vessel since the environmental demands of the new port are among the most stringent in the world. For this reason, the design will be based on the recently launched Wärtsilä HYTug, which features hybrid propulsion and energy storage using batteries.
The Wärtsilä HYTug emphasises environmental sustainability, operational efficiency, and lower fuel consumption than is possible with conventional tug designs. The ‘first-of-its-kind’ fully integrated hybrid power module combines engines, the energy storage system, and power electronics optimised to work together through a newly developed energy management system (EMS). It marks a new frontier in marine hybrid propulsion.
The fuel efficiency of this design has the added benefit of reducing exhaust emission levels. Furthermore, when operating in ‘green’ mode, it is unlikely that there will be any visible smoke from the Wärtsilä HYTug since the load is being picked-up by the batteries. At the same time, the noise level of the tug will be notably reduced.
“The Wärtsilä HYTug will change the landscape of the tugboat market as battery usage significantly increases environmental sustainability and operational efficiency, while at the same time greatly reducing operating costs. It represents further evidence of Wärtsilä’s leadership position in sustainable and energy efficient technologies,” says Marine Solutions' Sales Manager, Mário Barbosa. 
“Green port operations are completely aligned with Petrocity’s corporate philosophy and values. We look forward to working with Wärtsilä in developing the kind of harbour tug that meets the criteria that have been established for this project. This will be the first of many others in a huge logistics project which aims at the regional integration of the Espirito Santo, Minas Gerais and Bahia states. It represents a definitive guarantee of the interiorization of the economy in the north of Espírito Santo,” says Mr José Roberto, CEO Petrocity.
The new hybrid vessel features a very distinctive outlook while providing the power and manoeuvrability for practical tug operations. The overall design has been optimised for low hull resistance, high towing and escort performance, efficient sea-keeping, crew safety and comfort, as well as for easy maintenance.
Wärtsilä in brief
Wärtsilä is a global leader in advanced technologies and complete lifecycle solutions for the marine and energy markets. By emphasising sustainable innovation and total efficiency, Wärtsilä maximises the environmental and economic performance of the vessels and power plants of its customers. In 2016, Wärtsilä's net sales totalled EUR 4.8 billion with approximately 18,000 employees. The company has operations in over 200 locations in more than 70 countries around the world. Wärtsilä is listed on Nasdaq Helsinki. www.wartsila.com

Corvus Energy has been awarded both “Supplier of the Year” and “Innovation of the Year” at the 2017 Electric & Hybrid Marine Awards being held at the Electric & Hybrid Marine World Expo. This is the third consecutive year that Corvus has received the Supplier of the Year award and a first time win for Innovation of the Year. The award recipients are decided up on by a panel of highly regarded industry experts.
“Battery technology is at the heart of electric and hybrid marine propulsion technology. Corvus is a true leader in this area and its growth and achievements in 2016 serve as a reminder of how important this company continues to be,” says awards panel judge Martyn Lasek, editor, Ship & Bunker.
The awards were presented to Willie Wagen, Corvus Energy Global VP of Sales & Marketing and Managing Director of Europe, on the final day of another very successful Electric & Hybrid Marine Expo taking place in Amsterdam. “The team at Corvus is very pleased to have been selected once again as Supplier of the Year and extremely proud to have also been awarded Innovation of the Year for the industry leading Orca ESS”, says Wagen. Adding, “over a year ago Corvus set out to design and develop the world’s best energy storage system. The result of that was Orca ESS, the safest, highest performing, and most cost effective ESS for all-electric and hybrid applications. Orca ESS is accelerating the transition to electrification for many operators and ship owners. No other firm understands this technology and industry better than Corvus and we have the greatest number of installations & upcoming projects to prove it.”
Further recognition from awards judges: “Corvus’ exceptional growth and high spending on R&D merit recognition for a third consecutive year as the company’s innovative solutions, and especially the Orca ESS, gain rapid acceptance among customers” – Jack O’Connell, senior editor, The Maritime Executive.
Following the successful launch of Orca ESS at the Electric & Hybrid Marine World Expo one year ago, Corvus has won over 2 dozen new projects totalling over 15MWh that will utilise Orca ESS. In total, Corvus Energy has deployed 80+ installations with over 43MWh installed and exceeding 1 million operating hours. Corvus has unsurpassed experience and knowledge that enables revolutionary innovation.
“Corvus has shown again why it is at the forefront of one of the fastest-growing maritime sectors. An impressive performance that bodes well for the future for the company,” concludes Rich Miller, managing editor, Professional Mariner and American Ship Review.
