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.

Teekay's next gen shuttle tankers will burn LNG and recovered VOCs

JANUARY 9, 2018 — Four next generation shuttle tankers on order for Teekay at shipbuilder Samsung Heavy Industries (SHI) feature a broad range of Wärtsilä's latest technology innovations that are expected to reduce annual emissions of CO2 equivalents by more than 40 percent, compared to conventional shuttle tankers.
In addition to operating on Liquefied Natural Gas (LNG) as the primary fuel, the ships' dual-fuel engines will also be able to run on a mixture of LNG and recovered Volatile Organic Compounds (VOC) – the gas evaporating from the oil cargo tanks during loading.
By utilizing the recovered VOC as fuel rather than venting it to the atmosphere, the harmful emissions will be eliminated and the ships' bunker needs will be significantly reduced.
The concept also means that NOx emissions from the engines' exhaust will be reduced by more than 80 percent, SOx emissions will be almost entirely eliminated, while particulate emissions will be reduced by more than 95 percent.
These environmental benefits are matched by equally important economic advantages, with a significant reduction in fuel consumption compared to conventional solutions.
"Together with Teekay, we have developed a concept that takes the shuttle tanker sector into a new era, and which is further evidence of Wärtsilä's ability to transform shipping by developing and utilizing the very latest technologies," says Roger Holm, President, Wärtsilä Marine Solutions. "These ships will have tremendous operational flexibility with unmatched maneuevring capability, and will achieve what all operators are striving for today, namely optimal economic and environmental performance."
"This new shuttle tanker design will set new standards for both fuel consumption and CO2 emissions," says Terje Rusdal, Project Manager at Teekay.
Among the many innovative features of the design is the Wärtsilä Hybrid system, on which the power distribution will be based. The Hybrid system uses batteries for fuel savings, peak load shaving, and added overall system redundancy. This directly impacts the main machinery, resulting in fewer running hours with correspondingly lower maintenance time and costs.
Wärtsilä's broad scope of suppy also includes the full electric and automation system, which includes the Wärtsilä Low Loss Hybrid (LLH) system and batteries, the Wärtsilä LNGPac fuel storage and supply system, the Wärtsilä VOC system for recovering and liquefying the VOC with a storage and supply system, Wärtsilä 34DF dual fuel gas engines, the fuel mixing system with liquid VOC and LNG as the main fuel for the engine, gas turbines to handle the surplus gas, Wärtsilä cargo and ballast pumps and a Wärtsilä inert gas generator.
Also included in Wärtsilä's integrated solution for this vessel concept is Eniram's Vessel Performance Management system. Eniram, a Wärtsilä company, will provide a data collection platform having the capabilities to optimize the vessel's operations, while also providing the owners with analytics and reporting. The Performance Management system ensures that the full potential of the vessel as well as the fleet, will be utilized.

Facing up to the reality of a much smarter marine future

The shipping industry is not going to be (and should not want to be) spared an increasingly inter-connected future. New technologies that were considered completely unachievable just a few years ago are rapidly being introduced, creating new levels of efficiency and cost savings that are influencing the future of shipping. We at Wärtsilä have committed ourselves to being at the forefront of these changes.
By utilising high levels of connectivity and digitalisation, we intend to lead the way to a Smart Marine Ecosystem. We are building upon our broad product and service solutions base to support innovation, while collaborating with customers and partners, including ship owners, ship management companies, ports, bunker suppliers, and software or technology providers, among others in order to realise this vision.
To support this approach we have, among other initiatives, developed Digital Acceleration Centres (DAC) to speed up the innovation process and to work with customers in co-creating new business models and solutions. One DAC is already established in Helsinki, Finland, with another scheduled to be opened in Singapore before the end of the year. We plan to open two more in 2018; one in Central Europe, the other in North America.
The results of this work are already apparent. In August, in cooperation with our customer Gulfmark Offshore, we successfully tested the remote controlling of the ‘Highland Chieftain’, an 80-metre long platform supply vessel owned by Gulfmark Offshore. This was carried out by satellite from a distance of 8000 kilometres using standard bandwidth, and without the use of any land-based technology for communications between the vessel and the remote operator work station. Remarkably, the vessel was sailing off the east coast of Scotland, while it was being remotely operated from Wärtsilä premises in San Diego, California.
While complete ship autonomy is unlikely to be fully in use for a while yet, hybrid propulsion using a combination of engines and battery storage is already established and becoming increasingly popular. It is estimated that hybrid propulsion solutions will represent a significant percentage of all contracted ships within the coming ten years.
By leveraging our strengths in both engine design and electrical & automation systems, we have launched a fully integrated hybrid power module, the Wärtsilä HY, optimised to work seamlessly through a newly developed energy management system (EMS). Notably, it is the marine industry’s first hybrid power module of its type produced, thereby establishing a new industry benchmark.
No innovation can succeed without clear benefits to its end user, and we are proud that the Wärtsilä HY provides many of them. For example, we can identify lower fuel consumption, reduced exhaust emissions, and improved vessel performance. When operating in ‘green’ mode, zero emissions can be achieved, while smokeless operation is also achievable at all load points and in all operating modes, thanks to a patent pending automation procedure.
We passionately believe in a better connected, more efficient and environmentally sustainable shipping industry, made possible by a Smart Marine Ecosystem – join us on this journey and stay tuned for more exciting developments.


ABS: New Guidance on Energy Storage

ABS has published The ABS Guide for Use of Supercapacitors in the Marine and Offshore Industries (Supercapacitor Guide) to support safe application of hybrid power in the marine and offshore industries.  
The maritime industry is increasingly interested in using supercapacitors as an energy storage solution when quick energy delivery is required during a peak loading condition. Particularly, offshore supply vessel (OSV) owners are considering supercapacitors to supplement energy supply during high-load operations, such as using power thrusters for dynamic positioning while station keeping. 
"We are developing a series of guides on energy storage systems so our clients have as many options as possible to effectively manage energy use,” said ABS Senior Vice President of Engineering and Technology, Derek Novak. “Supercapacitors have a high power density and a fast charging and discharging process to augment other power sources – which can greatly improve the efficiency of traditional energy sources.” 
The Supercapacitor Guide delineates types of supercapacitors, including electrochemical capacitors and lithium ion capacitors, and defines requirements for design, construction and installation of supercapacitors in marine and offshore applications. 
“As a leading class organization, we provide our clients and industry with reliable guidance to enable technology development that affords safer and more efficient operations,” said ABS Chairman, President and CEO, Christopher J. Wiernicki. “We focus on staying ahead of the curve so industry can leverage alternative energy sources to reduce costs and improve productivity.” 
The guide, available for download from the ABS website, is the second in a series on hybrid electric power systems following the ABS Guide for Use of Lithium Batteries in the Marine in Offshore Industries. ABS also issued the ABS Advisory on Hybrid Electric Power Systems, which takes a measured approach to evaluating potential advantages and disadvantages, challenges and level of readiness for the primary hybrid electric power systems and components most suited for marine and offshore applications.  

EUROPE: CATERPILLAR MARINE TECHNOLOGY ORDERED FOR HYBRID TUG


The Cat Marine Advanced Variable Drive is to be installed on a tugboat to be built by Turkey’s Sanmar Shipyard.
Announcing the contract, Caterpillar Marine said that its AVD will offer improvements in fuel efficiency and vessel performance by means of a fully-integrated hydro-mechanical propulsion system.
‘Different from a typical Power Take In (PTI) solution, the AVD incorporates a planetary gear set allowing seamless clutch engagement of main engines, auxiliary engines, or both to provide a scalable power installation to meet any customer need in terms of maximum vessel speed, power, or bollard pull,’ explained Nathan Kelly, product definition engineer for Caterpillar Marine. 
‘This also allows propeller speed independent of engine speed so optimal engine efficiency can be achieved leading to fuel savings of 15%-20%.’
The Sanmar hydraulic hybrid tug will be a Robert Allan Ltd-designed RAmparts 2400SX harbor tug incorporating an integrated Caterpillar AVD system of 3512 main engines, a C32 auxiliary engine, Cat MTA 627 fixed pitch tug thrusters, and bridge controls.  
Compared to a conventional tug with equivalent bollard pull, the return on investment is estimated at three years or less, based on projected fuel and operating cost savings.
Ali Gurun, director of projects, Sanmar Shipyards, commented on the new vessel initiative: ‘This strategic development between Sanmar and Caterpillar will provide a highly optimised, lower cost alternative to conventional electric hybrid systems with similar benefits regarding improved performance, lower noise and lower emissions.’

Marine battery market is charging up rapidly

Hybrid propulsion with batteries is changing marine propulsion for the better, and not just in the OSV sector.

Earlier this month I noted that although the market for offshore support vessels remains depressed for the time being, when it recovers, all newbuilds will have batteries. Well, maybe not absolutely all of them, but a good number of those built for more sophisticated markets.

Battery suppliers such as Plan B Energy Storage predict that most new vessels will have a battery room, with options for energy storage either integrated at the newbuild stage or added later. If not a battery room as such they may well have a containerised/modular battery pack.

As I noted here,  recent months have seen further important developments in battery-based hybrid energy systems for OSVs, including a platform supply vessel in which a hybrid power system replaced a generator.

Norway’s NOx funds wants to help owners refitting vessels that are on long-term contracts with hybrid energy solutions based on batteries. It has set a deadline for of 30 June 2018 for owners who want to apply for support for PSVs engaged on term charters.

This week also saw global aluminium supplier Hydro make a significant investment in Corvus Energy, which has number of contracts for batteries for OSVs. Hydro sees energy storage and battery solutions as an increasingly important part of the future of energy systems as whole. It’s right to do so. Batteries are being fitted on all kinds of vessels, from tugs to ferries to research ships. FinFerries and Siemens talk about the hybrid ferry Elektra here.

For the time being, the batteries in hybrid energy solutions for ships are being supplied by OEMs, but given the way demand is growing I’m sure it can’t be long before one of the battery companies is snapped up by a major marine industry player.

Hybrid Partnership Gains First Project

The MAN Diesel &Turbo and AKA partners have recently received an order in connection with the building of a multi-purpose supply vessel for a federal Russian agency. The order inlcudes four MAN 7L21/31 gensets, including alternators, with AKA’s scope of supply for the order being a complete 690V main switchboard, 690-400 V transformers, and electric motors for main propellers and thrusters. Plus AKA’s delivery of he frequency converters for the electric motors and the drive control and power-management systems.

MAN Diesel & Turbo is reporting its first order from its 40% stake in Aspin Kemp & Associates (AKA), a specialist power supply, energy management and drive systems for marine applications.
The partners said the first order is for a hybrid propulsion package for a Russian special vessel. Delivery is scheduled for March 2018 in St. Petersburg and marks the first successful collaboration between the two since MAN Diesel & Turbo bought its share in AKA in June.
The order includes four MAN 7L21/31 gensets, including alternators, with AKA’s scope of supply for the order being a complete 690V main switchboard, 690-400 V transformers, and electric motors for main propellers and thrusters. Also within AKA’s delivery is the frequency converters for the electric motors and the drive control and power-management systems. (Energy management systems provide fully automatic control and optimize the power distribution of drive components of ships.)
“This specialist vessel, with its unique operational demands, showcases our competence as a solution provider and the broader capability we now possess with AKA’s energy-management expertise,” said Wayne Jones, chief sales officer, MAN Diesel & Turbo.  “Encouragingly for our new partnership, the previous vessel in this series was equipped with an identical propulsion package, but from a different supplier.”
The partnership is part of MAN Diesel & Turbo’s strategic development program, “Basecamp 3000+”, launched in 2016. As part of this program, the company announced strategic acquisitions and partnerships to expand its product range with respect to the global trends of de-carbonization and digitalization.
“The partnership with AKA is a key element in our strategy to strengthen our role as technological forerunner in the field of marine propulsion”, explained Uwe Lauber, CEO of MAN Diesel & Turbo. “AKA’s specialized expertise links battery storage systems and marine engines. The new cooperation marks an important step on the way to further establish ourselves as a principal system supplier for energy management on board ships.”
AKA is a Canadian company, based in Montague, Prince Edward Island (PEI). The company employs around 120 at five global locations with about 100 in its PEI locations.
In June 2017 MAN Diesel & Turbo agreed to acquire 40% in AKA. By the acquisition, MAN Diesel & Turbo said it has gained specialized know-how in the field of electric and hybrid systems to complement its product portfolio.
AKA co-founder and CEO Jason Aspin remains with the company as managing director and shareholder. Neale Kemp, the other founding partner. is retiring from active business operations and selling his shares in AKA.
MAN Diesel & Turbo said AKA is known as a world market leader in equipping diesel-hybrid powered ship propulsion systems with integrated battery storage and in high-reliability on-board power systems in dynamic-positioning applications for the marine and offshore oil & gas sectors. The company is also involved in energy storage and hybrid power solutions for a broader range of marine and land-based applications.
“MAN Diesel & Turbo is the world’s premiere designer and manufacturer of marine propulsion systems, and the perfect partner for us,” Aspin said. “We benefit not only from the global prestige of the brand, its global sales network and customer base, but also from the top-class engineering and machine building competence in the fields of engines, exhaust gas after treatment and gas and propulsion systems.”
