HYDROGEN ENGINE RETROFIT PAYOFF
One off shore wind crew transfer operator has benefi tted from reduced fuel usage and emissions with catalytic hydrogen technology
Tidal Transit’s off shore wind energy crew transfer vessel Kitty Petra was fi tted with the Ecomotus EcoPro catalytic hydrogen system in 2020 and Leo Hambro, commercial director, believes that the reductions in vessel fuel consumption and CO2 and NOx emissions have been tangible.
“We are very excited to have another ‘industry first’ on the road to decarbonising the marine industry. Ecomotus’s intelligent system has shown that it reduces fuel usage and resultant CO2 emissions by 20% while also slicing 67% of our NOx emissions. It is phenomenal and I only wish we had invented it!,” he said.
CLEVER TECH
Ecomotus is a UK research and development company and its EcoPro system is designed to inject pure hydrogen into the vessel’s engines through the air filter, thereby ensuring a 100% fuel burn in the combustion chamber and a quicker combustion cycle.
Adrian Bartlett from Ecomotus explained that retrofitting the system to Kitty Petra’s MAN engines and its Kohler generator has enabled the company to work closely with Tidal Transit helping its skippers to use the data provided by the system to achieve the best balance of vessel performance and fuel economy.
“Using Kitty Petra’s wi-fi we can monitor the EcoPro system in real time and, if necessary, adjust it to ensure the efficiency of the vessel’s engines.”
“A dashboard is also provided to enable vessel owners or fleet managers to monitor the system’s operation at any time,” he said.
With over 400 CTVs currently operating in the offshore energy marine sector, Mr Hambro has calculated that if each vessel uses approximately 1,500 litres of fuel per day for 250 days per year, a 20% reduction in fuel would save a staggering 30 million litres of diesel (78,000 tonnes of CO2) annually, with over 60% reduction in NOx emissions.
He said: “I believe the Ecomotus system is now ready for mass adoption by the offshore energy crew transfer vessel sector to reduce Scope 1 and Scope 3 emissions and save fuel costs.”

Autonomous ferry charging solution
Two Nowegian ferry connections are being kitted out with autonomous charging solutions.
The electrification of another two Norway ferry connections will be realised thanks to Zinus’ autonomous charging solution selected by the automation group, SEAM.
“Together with Zinus, SEAM has previously delivered charging systems to several ferries. In our opinion, Zinus offers efficient technology with good charging capacity. The Zinus system is also very elegant in appearance and the charging tower’s footprint makes it both easy to place and space-saving on the quay,” said Karl Norheim, project manager at SEAM.
“Furthermore, the solution is very flexible in relation to installation height, which is an advantage in ferry connections with large tidal differences.”
This latest order adds to the company’s order history of supplying electrical charging infrastructure to the ferry traffic along the Norwegian coast. Supply includes four telescopic charging towers of the Charging Telescopic Autonomous type to be installed on the ferry quays, as well as four charging connections to be installed on board the two ferries that operate the fjord crossings.
When combined, the charging tower and connection form an autonomous system that charges electric ferries fully automatically at call. Connecting the ferries to the power supply only takes around 20 seconds and the system can transmit a current of as much as 4,400 amperes. In total, Zinus now has delivered or to order Charging Telescopic Autonomous systems for 24 ferry connections, spread across several nations.
Zinus specialises in the supply and fabrication of handling systems for shore power and charging to a wide on and offshore market.

The Fastwater project aims to build on Methanol’s numerous references as a simple to adopt sustainable marine fuel.
The Fastwater Consortium and the Swedish Maritime Administration (SMA) recently successfully demonstrated a pilot boat which has been converted to operate on Methanol fuel.
The demonstration in Stockholm Harbour follows the successful bunkering of the vessel at the SMA pilot station in Oxelösund, Sweden, where the pilot boat will be based.
The event was addressed by Members of the Swedish National Parliament Johan Büser and Anders Hansson who spoke to the importance of alternative fuels like Methanol in reducing carbon and pollution emissions on a local and national basis. Low carbon energy available to shoreside facilities using renewable electricity are hard to replicate onboard ship so for the myriad of small craft - tugs, enforcement vessels, dredgers and pilot boats - other sustainable solutions are needed.
Faced with the problem of needing to cut emissions quickly, port and harbour authorities are examining and investing in methanol as an option that can virtually eliminate air pollution and contribute towards lower carbon.
Methanol single or dual fuel engines are very similar in design to conventional diesel engines with the Methanol fuel supply system designed to meet prevailing safety standards.
The GreenPilot project run by SSPA has demonstrated that it is feasible to convert a pilot boat to methanol operation using available technology. Spark ignited engines with port injected methanol were found to have engine efficiency similar to diesel engines. Emissions reductions were substantial compared to conventional fuel oil.
With funding from the European Commission, Fastwater focuses on high impact outcomes, designing retrofit solutions for existing ships and designs for newbuildings, employing Methanol as a future-proof alternative marine fuel to create a fast track to carbon neutral shipping.
The project aims to commercialize medium and high-speed Methanol-fuelled engines for shipping. Consortium members, including OEMs, shipyards, naval architects, ship owners/ operators, port and maritime authorities, classification, fuel producers, and research institutes, will demonstrate feasibility on three vessels running on methanol fuel: a harbour tug, a pilot boat, and a coast guard vessel.
In addition, Fastwater will provide training programs for vessel crew and portside staff, develop rules and regulations for Methanol marine fuel use and demonstrate the complete value chain for bunkering methanol.

HYDROGEN PROPULSION SYSTEM LAUNCH
A full scale hydrogen based propulsion system has been launched by Kongsberg
The HySeas III is a tested and verifi ed full-scale, zeroemissions ship drivetrain powered by hydrogen fuel cells.
“With a verified and tested hydrogen-based propulsion system, we take the next step in zero-emission solutions at sea. This project is another example of our world-leading Norwegian maritime cluster succeeding when we face the most demanding technological challenges,” said Geir Håøy, president of Kongsberg.
EU PROJECT
The project is the third and final part of the EU funded project “HySeas” which has been running since 2013 to prepare and demonstrate a scalable hydrogen system for ships and ferries.
In this final stage, Kongsberg has built a full-scale electric propulsion system based on hydrogen-powered fuel cells at Ågotnes outside Bergen. The system will now undertake a four-month testing program for validation purposes with the aim of verifying the final design for an H2-powered RoPax ferry. Testing is intended to demonstrate the ease with which H2 fuel cells can be successfully integrated with a proven marine hybrid electric drive system.
The testing mirrors the operational loads which would be experienced by a vessel on a route between Kirkwall and Shapinsay in Orkney. It will confirm safe operation and power and fuel capacity requirements, together with other valuable information to feed back to the vessel design team at Caledonian Maritime Assets Ltd (CMAL) in Scotland. CMAL plans to complete the design in March 2022. Hydrogen fuel will be generated through wind power at the ferry port.
“If we are to succeed with hydrogen investment in Norway, both to reduce national emissions and create new, green and sustainable jobs, we are dependent on being able to show complete pilots on a full scale,” said Egil Haugsdal, CEO of Kongsberg Maritime. ”This means that the next step will be to show the technology in operation, and then quickly put in place the surrounding infrastructure. Orkney will be the first practical usage of this technology while the Norwegian maritime cluster has the opportunity develop our own pilots and projects here in Norway.”
This project is the third and final part of the EU funded project “HySeas” which has been running since 2013 to prepare and demonstrate a scalable hydrogen system for ships and ferries.

Waterjet variant off ered for diesel outboard
8 The OXE Jet-Tech waterjet performance
is claimed to be equal to or better than propeller version Jet-Tech Propulsion LLC has partnered with Diesel Outboards LLC to introduce a highperformance waterjet option for the OXE diesel outboard.
The Jet-Tech unit is manufactured as a direct bolt-on replacement to the standard lower unit on OXE Diesel models by OXE.
It is a single stage compact high performance waterjet which combines mixed-flow properties within an axial design build, with a hybrid stator for high torque diesel outboard engines and others. One jet fits every OXE Diesel model manufactured. This approach is claimed to combine the key benefits of excellent high-speed efficiency with superior cavitation margins at lower speeds and high load conditions.
The Jet-Tech waterjet’s performance is claimed to be equal to or better than propeller versions and is matched 1:1 to the unit horsepower-driven prop outboard. “By using advanced proven waterjet engineering and design capabilities, augmenting the innovative OXE Diesel design, we completely redefined outboard motor propulsion and performance. The Jet-Tech unit is designed to grow with our expanding product line as it is a fully scalable product. The patented design will expand into the vertical shaft diesel/gas outboard waterjet applications and inboard waterjets” said Douglas Natoce, President Jet-Tech Propulsion LLC, and Diesel Outboards LLC
SILENT SAILING THROUGH ANTARCTIC ICE
The new Antarctic Supply & Research Vessel (ASRV) Nuyina for the Australian government has arrived at its home port of Hobart in Tasmania
Bakker Sliedrecht supplied the fl exible electric propulsion
for the special (Damen built) vessel, enabling the Nuyina
to sail both electrically and in hybrid modus and break through the Antarctic ice at full power.
The Nuyina can sail in temperatures of forty degrees below zero and break through 1.65 meters thick ice at a speed of three knots. The name Nuyina is the Tasmanian Aboriginal word for southern lights.
The hybrid propulsion enables the Nuyina to sail in different modes. It can sail entirely on diesel to get from A to B as quickly as possible. Fully electric for quiet and economical sailing or on a diesel engine and an electric motor, where the other diesel engine generates energy. In the icebreaker mode, the diesel engines as well as the electric motors and thrusters can be used at full power. In DP mode, those thrusters hold the ship in position.
Bakker Sliedrecht supplied four water-cooled frequency drives that can be deployed multifunctionally, for the two propulsion motors 3700kW each or for the three thrusters with 1300kW electric motors at the stern, three thrusters with 1300kW electric motors for the bow and two transformers for the Power Take Off/Power Take In system. (PTO/PTI). This generates power for propulsion as well as for other purposes, such as on-board voltage. The thrusters are used for both propulsion and the Dynamic Positioning (DP) system that keeps the ship in position. Bakker Sliedrecht provided training for the Australian crew to help them get to know the installation and to operate all the modes of electric propulsion. Due to the corona measures, the training was given online.
“From the first application in 2013 to completion in 2021, Bakker Sliedrecht was directly involved in every phase of this complex project. The vessel had to be able to sail under very difficult circumstances and heavy weather conditions. It also needed a hybrid propulsion. That made it technically very complex and the project very challenging,” says project manager Arie de Jong of Bakker Sliedrecht. “That is reflected in the construction time. We received the first order in 2016 and it was delivered in the summer of 2021. However, the Nuyina has become a state-of-the-art ship with unique features. We as Bakker Sliedrecht and its project team are proud of that.”
