WÄRTSILÄ NEXT GENERATION NAVIGATION SIMULATOR TO POWER THE CENTRE OF EXCELLENCE IN MARITIME SAFETY IN SINGAPORE
Wärtsilä Voyage will deliver the next generation navigational simulator for Singapore’s Centre of Excellence in Maritime Safety (CEMS) to prepare seafarers for shore-based remote management of vessels and autonomous ship operations. CEMS is a collaboration between the Singapore Maritime Institute (SMI) and Singapore Polytechnic, supported by the Maritime and Port Authority of Singapore. The next generation simulation platform will be based on the Wärtsilä NTPRO (Navi-Trainer Professional 5000) Navigational Simulator in a shore-based operational configuration.
CEMS will execute research and development in multiple skills with the support of augmented, mixed, and virtual reality. The project will focus on new modelling and simulation tools that enhance marine and navigational safety, the development of a complex port environment, as well as validation of new operational concepts, particularly with smart and autonomous ships.
“This is a strategically important partnership as CEMS and Wärtsilä Voyage share common objectives of introducing next-generation smart marine technologies safely and with a human-centric approach, both on the vessel and on the shore side. We look forward to working with CEMS and link-minded global partners to advance this important topic,” said Chris Chung, Director, Ecosystem Development, Wärtsilä Voyage.
“As the maritime industry gets more digitally connected, it is opportunity to embark on a journey to identify and define new skillsets that could be radically different from today. CEMS shares a common vision with Wärtsilä Voyage to embrace technologies and prepare our workforce to be future ready through research and innovation,” said Daniel Zhang, Centre Director, CEMS at Singapore Polytechnic.
Wärtsilä Voyage’s collaboration with CEMS covers three core disciplines of seascape, landscape and mathematical modelling of all relevant vessel types for training shore-based navigation officers, as well as the development of training material for remote operations. These include areas such as assistive technologies for use onboard ships and during training, simulators to study human behaviour and competency to enhance the safety of navigation, infusing wearable technologies, and co-develop scenario-based “Standards Validation” simulation for autonomous vessel research. The research concepts and projects will be conducted over the next two years.
Recognizing the long-term need of creating an environment to promote data-driven innovation and developments in the maritime sectors, the Singapore Maritime Institute has also signed a Memorandum of Understanding agreement with Wärtsilä Voyage. Under this, the two parties will continue to cooperate and identify industry challenges that can be resolved through data-driven tools, applications, and technologies, as well as provide researchers with relevant and anonymised data to support their work under SMI’s Maritime AI R&D Programme.
“The project is of high significance as it paves the way for future collaborations and projects not only in the Asia-Pacific region but with the global industry where Wärtsilä Voyage’s simulation platforms can act as safe testbeds for validating all kinds of smart marine and autonomy technologies,” said Pierre Guillemin, Vice President, Technology at Wärtsilä Voyage.
“AI and simulation tools not only provide us with the unique platform to safely test and validate a myriad of situations and environments before going for actual sea trails, but they also give mariners ample opportunity to get used to the new technology without any risk,” added Guillemin. “We, therefore, see this collaboration as the perfect opportunity and example of how different stakeholders within the industry can come together to leverage big data and combine their expertise to develop and implement smarter technologies faster, and catapult shipping’s transition towards sustainability.”
Protecting The Future Of Green Vessels With Green Fire Technology
The world is going electric - and this is undeniable! Be it on land, at sea or in the air - industries and technologies are starting to catch up - and at times exceed - fossil-fuel powered means of transportation.
In the marine industry cargo ships, naval ships, submarines and even special purpose marine vessels are fast adopting electric power. Similarly, the luxury yacht market has entered an era of eco-consciousness as builders and suppliers work together to source and develop sustainable solutions. These efforts are focused on reducing consumption and emissions, as well as improving speed and above all safety.
The International Maritime Organization (IMO) estimates that the amount of human-instigated carbon dioxide emissions from shipping is expected to rise by 50 – 250% by 2050 if no action is taken. New propulsion systems that consume less fuel, and hybrid yacht batteries that motorise the vessel voyage for hours of silent and fuel-less transportation, are emerging on the horizon. Growing interest in energy storage from the sea vessel industry is already leading global battery manufacturers to accommodate the rising demand for electric and hybrid marine systems.
The advantages from powering yachts with batteries are well known, just as much as the risks that come with them. A European Maritime Safety Agency (EMSA) report concludes that a Li-Ion battery fire onboard a ship can be more deadly than a sinking ship. The authors point out that the commonly used fire suppression systems are not effective in case of a battery fire, and in some cases may even worsen the situation.
Mechanical shocks or misuse of a Li-Ion battery may lead to an increase in its internal temperature, triggering what is known as a thermal runaway. During a thermal runaway, the battery electrolyte releases toxic and potentially explosive off-gases along with excessive heat. The resulting fire can ignite the electrodes of the battery and is of such high intensity that it is difficult to extinguish or contain.
FirePro, a leading manufacturer of condensed aerosol fire suppression systems, has carried out extensive research, with more than 70 tests over the past 5 years, aimed at understanding the diverse behaviour of fire on such batteries. The FP technology has been thoroughly tested regarding effectiveness and efficiency by accredited laboratories including KIWA (Netherlands) and Albarubens (Italy) as well as by prominent Li-Ion battery manufacturers such as LG Chem. Moreover, prominent manufacturers such as Samsung SDI are using FirePro for their Energy Storage Systems (ESS).
Additionally, FirePro has been working closely with shipyards and end clients, designing solutions for small to large Li-Ion battery ESS’s. Noteworthy installations include those on the Baltic 142 Canova luxury super yacht and the Aurora pioneering ferry boat.
Baltic Yachts is a European superyacht building company based in Larsmo, Finland. It is considered as one of the world leaders in the design, engineering, and construction of high-performance carbon composite yachts. FirePro systems are currently installed in the engine room of Baltic 142 Canova to protect both its engine and its critical electrical equipment.
The Aurora is a ferryboat operated by ForSea (HH-Ferries), a European operator based in Helsingborg, Sweden that supports ‘sustainable’ ferry routes. FirePro systems protect four Battery Energy Storage Systems on board the Aurora.
Despite the risks and difficulties, there is nothing slowing the marine industry from going electric, and therefore fire suppression technology must progress and adapt accordingly. FirePro is embracing the change and is constantly helping to shape the future of fire protection against battery fires.
FirePro has a team of expert partners in Singapore who are ready to help and advise on Marine Fire Protection as well as specific FirePro solutions. Alarm Supply Pte Ltd has been installing and commissioning Marine systems successfully for many years and can showcase a large portfolio of projects and clients.

SURVITEC ENHANCES LIFEBOAT INSPECTION SOLUTION TO DELIVER SAVINGS AND FLEXIBILITY FOR SHIP OPERATORS
Leading survival technology provider Survitec has relaunched its lifeboat inspection solution underpinned by the company’s novel ‘Hub and Spoke’ network model.
Lifeboat Inspection 402, devised in line with regulations mandated in 2020 under SOLAS Chapter III & IMO MSC.402(96), has been enhanced to deliver greater flexibility and convenience to vessel operators.
Metkel Yohannes, Survitec’s Lifeboat Product Category Manager said: “We have significantly optimised our global lifeboat inspection solution to better reflect the operational needs of our customers and local dynamics.
In addition, our Lifeboat Inspection 402 solution includes further enhancements to its agreement options. For instance, as well as traditional spot market lifeboat inspections, Survitec offers more cost-effective frame or subscription-based agreements. Customers can benefit from lower costs, port priority and due-date management – all from a single point of contact.
Lifeboat inspections must be carried out annually, with a more extensive inspection and load testing taking place at five-year intervals. But, as Yohannes explained, waiting until the certificate’s expiry date to sort out an inspection is not the most efficient approach.
“This is where the Hub and Spoke model combined with the available agreement options really comes into its own.
“The hub is the main port where our multi-skilled technicians are based, with spokes radiating out to secondary ports. Fully approved and authorised lifeboat inspections can be carried out at any port along the spoke. It has been developed to deliver transparent and predictable pricing, but also a greater degree of operational flexibility and convenience.”
Paul Watkins, Survitec’s Regulatory and Compliance Manager and Chair of the Technical Committee for ILAMA, added: “We want to simplify the lifeboat inspection process and demystify regulation, so our customers have total confidence in their safety equipment. Our Lifeboat Inspection 402 offer delivers a more effective way to achieve compliance and help keep our customers’ vessels operational and our seafarers safe.”
As a Flag State authorised multi-brand lifeboat inspection provider, our teams are competent, capable and certified to deliver on all makes and types of lifeboats, davits, and hooks.
Hub ports currently include Singapore, Rotterdam, Fujairah, Shanghai, Doha, Barcelona, Miami, Busan, Aberdeen, Algeciras, and Piraeus. Over 60 Flag Administrations have now authorised Survitec’s Hub & Spoke lifeboat inspections.

ROLLS-ROYCE SUPPLIES mtu GAS ENGINES FOR WORLD’S FIRST LNG TUGBOAT WITH HYBRID SYSTEM
Rolls-Royce is supplying two mtu 16V 4000 M55RN gas engines to Sembcorp Marine Integrated Yard for the construction of the world’s first liquefied natural gas (LNG)-hybrid powered tug. The harbour tug will be operated in Singapore by Jurong Marine Services, a wholly owned subsidiary of Sembcorp Marine. The new LNG-hybrid tug is the first of 12 tugs that Sembcorp Marine plans to design and build to replace the existing diesel-powered ones between now and 2025.
“We are very happy to be part of Sembcorp Marine’s efforts in environmental protection and adopt new green technologies in their operations. The mtu marine gas engines are part of Rolls-Royce’s Green and High-Tech programme. Without exhaust gas aftertreatment they emit no sulfur oxides only very small quantities of nitrogen oxide and particulate mass is below the verification limit”, says Chew Xiang Yu, Head of Rolls-Royce Power Systems’ commercial marine business in Asia.
This is the first LNG-hybrid tug to be powered by mtu gas engines worldwide. Designed by LMG Marin (Norway), part of the Sembcorp Marine group, to deliver 65T Bollard Pull (BP) with ABS Class, the LNG-hybrid tug is estimated to be completed in the later part of 2021. The main propulsion system of the tug comprises twin 16-cyclinder mtu Series 4000 gas units which will provide a combined total power of 2984 kilowatts at 1600 RPM (revolutions per minute). The new gas engines are able to deliver performance comparable to a high-speed diesel engine. Equipped with multipoint fuel injection, dynamic engine control and enhanced turbocharging, the engines cater for dynamic acceleration capabilities, high power output and reduced emissions considerably below the current IMO III limits without the need for exhaust aftertreatment. The LNG-hybrid propulsion system will be able to provide flexibility to cater for various operational modes and is able to switch between low emission liquefied natural gas (LNG) engines and zero-emission battery power.
The new mtu gas engines are already powering ferries operated by the Dutch shipping company Doeksen in the specially protected Wadden Sea. A Lake Constance ferry operated by Stadtwerke Konstanz will also start operating in 2021 with the new mtu gas engines.

HYDROMASTER INTRODUCES HIGH SPEED THUSTER FOR FAST CRAFT
HYDROMASTER, renowned for its self-contained outboard propulsion units, has recently introduced its latest addition to an already existing wide range of azimuth and tunnel thrusters.
Responding to the need for a fully steerable thruster for faster craft, the company has developed a range of thrusters able to operate with vessel speeds up to 28 knots, with favourable hull designs even up to 30 knots. Initiated by a request from and in cooperation with Damen Shipyards, two years of research and extensive CFD studies have resulted in a genuine 360 degrees steerable thruster. It has a highly streamlined low-drag underwater body, housing a set of high grade spiral bevel gears driving an optimised pulling type highly skewed Class I propeller.
It allows owners and naval architects to fit their latest commercial designs with a set of heavy duty thrusters combining superior propulsion efficiency with vessel speed and optimal manoeuvrability. Installing waterjets or other less efficient or non-commercial grade propulsion methods will be a thing of the past and the practice of installing rudders and/or bow thrusters will become obsolete. It will provide fast craft with much desired low-speed manoeuvring, perfect for quick berthing, while approaching landing points or platforms, it will greatly reduce turn-around times.
The application seems limitless with the recent developments and increasing demand for smaller sized fast craft, like CTVs and high speed ferries. The thrusters are suitable to integrate with any hull material, including aluminium, glass fibre or carbon fibre hulls. In the wheelhouse the use of a joystick system brings actions like side-stepping, astern and other fancy moves down to a simple one-hand control.
The HYDROMASTER high speed thrusters are available in a power range up to 900 kW in a L-drive configuration with vertical mounted electric motor and full electric steering, to cater for the latest generation of electric powered vessels. For direct diesel engine driven right-angle upper gearbox Z-drive versions are available. Gears and bearings have been sized to meet requirements of all internationally recognised classification societies, for a full continuous heavy-duty rating.
The first units will be delivered shortly to Damen Shipyards and find its application on a series of high speed river cats.

A journey of discovery: Volvo Penta and Danfoss Editron power two hybrid CTVs in the ultimate sea trial
MHO-Co’s two new crew transfer vessels (CTVs) – MHO Asgard and MHO Apollo – have been put through their paces, having traveled from China to Denmark. The 12,000 nautical mile journey was a voyage of discovery for Volvo Penta and Danfoss Editron, with the many lessons learned helping to create a tailor-made solution fit for the owner’s requirements.
Earlier this week, two new hybrid crew transfer vessels (CTVs) –MHO Asgard and MHO Apollo – arrived at MHO-Co’s headquarters in Esbjerg, Denmark, after making the 12,000 nautical mile journey from China’s AFAI Southern Shipyard. Measuring 34.4 meters in length and with an 11-meter beam, these vessels will be run by operator MHO-Co and service the Hornsea Project 2 offshore wind farm in the North Sea.
The vessels’ power system is the result of a collaboration between world-renowned developers of new propulsion technology – Volvo Penta and Danfoss Editron. The companies have developed a fully integrated solution made up of a Danfoss Editron electric drivetrain supported by Volvo Penta variable speed gensets that drive two of the first Electric Volvo Penta Inboard Performance System (IPS) units as well as two D13 Volvo Penta IPS units. The new IPS units have already achieved 1,000 hours of operation before even reaching the customer. This impressive milage has given all the teams time to test and adjust the system to create a tailor-made solution that fits the owner’s requirements.
“These systems are a very important first step towards the future of sustainable operations at sea,” says Mik Henriksen, CEO of MHO-Co. “We believe it is our shared responsibility to drive more sustainable solutions in the marine sector, and the best way to do this is through collaboration.”
Listening, learning, and tweaking
Danfoss Editron and Volvo Penta treated the journey from China to Denmark as a pilot project and a time to work with the captains and crew to tweak the novel technology onboard and make it as reliable and efficient as possible for the customer. The companies were able to test different power combinations, such as diesel-electric operation or diesel-only. In Dynamic Positioning System-mode (DPS-mode) fuel consumption is below 20 liters/hr. and can be as low as 17 liters/hr. which is exceptional for vessels of this size class.
All these tests were carried out with the captain and stakeholders, which meant the result was a solution that was fit for purpose for the operator’s requirements. From these initial learnings, the teams have started adapting the drivetrain – not just the motors themselves – to all-electric propulsion needs.
Volvo Penta also worked with captains during the design phase to reimagine existing systems. For example, to take the electric propulsion dimension into account, Volvo Penta created a completely new HMI. To do this, the company worked closely with the captains during the design phase. Volvo Penta took advantage of options offered by the power of plenty, different kind of captain controls, and reading diagnostics differently to develop the HMI.
“The design, build, and delivery of these vessels was all about teamwork and collaboration,” explains Erno Tenhunen, Danfoss Editron’s Marine Director. “Ultimately, these are learning projects on all sides. We are trying to push the limits of technology, and the best way to do this is to bring our unique ideas, perspective, and knowledge together. That’s exactly what we have done here.”
Before the vessels enter operation, batteries are being installed in Denmark to provide stored power for zero-emissions operation. This system will allow the vessels to operate in zero-emission electric mode for up to eight hours or, in combination with diesel propulsion, to achieve a maximum speed of approximately 24 knots. Using multiple modular generators allows operators to tailor power generation to the operational profile and enhance flexibly.
“We’re excited to see these vessels go into action in the North Sea. This pilot project has been hugely beneficial in helping us create the building blocks for future projects,” adds Jacob Vierø, Sales Project Manager, Volvo Penta. “Each operation will be different and require a tailor-made propulsion solution, but this project has allowed us to both develop the technology and collaborative process that can be adapted for future commercial operations.”
ENGINE ROOM FIRE SUPPRESSION
1. Aerosol Fire Suppression
The FirePro Aerosol system is a patented non-pyrotechnic solid potassium salt-based condensed aerosol fire suppression system. The system is tested and certified by various agencies such as the Underwriters Laboratory (UL), BV etc. Aerosol fire suppression is amongst the most efficient method in existing technology as it inhibits the flame chemical chain reaction directly. It is acceptable by the most marine Class as a fixed fire extinguishing system for special purpose rooms under the IMO regulation. Condensed Aerosol Fire Suppression systems are governed by the NFPA 2010.
The Aerosol unit consists essential of an initiator, the solid aerosol forming compound (SBK) and cooling material. The solid aerosol forming compound (SBK) is stable and non-toxic. All FirePro units are hermetically sealed internally which ensures that the life-shelf of every unit is at least 15 years. There is no pressurized gases, tanks nor are piping works required. The fire suppressant agent is certified and proven safe to be used in protected spaces containing sensitive electrical/electronic equipment. Most importantly the FirePro Aerosol unit is non-pyrotechnic.
2. In the Event of a Fire The fire detection system will automatically activate the visual and audible alarm on the control panel. The FirePro aerosol units can be activated by activating the Breakglass unit in the wheelhouse or near door, outside the engine room. After the pre-set delay timing, the Aerosol will automatically discharged. Observe for any re-ignition and do not open any door or hatch until a minimum of 10 minutes after the activation of the fire suppression system. Remember to open doors or hatches only slightly and with extreme caution. Ensure you are protected from any fire and gases that may still be present, and have a portable fire extinguisher at the ready for use if required. Replace and reset the FirePro system at the earliest opportunity.
3. Advantages of the FirePro Aerosol Engine Room Fire Suppression System
The proposed FirePro Aerosol Fire Suppression System has the following benefits.
*UL listed & BV certified (Marine Application)
Fire Suppression System And many other approvals and certifications, with test reports on engine test fires.
*No synthetic chemicals and residues
Aerosol (potassium carbonate) is non-toxic and is easily removed by ventilation of the hazard area. Pressurized gaseous fire suppressant all contain Fluorine and forms toxic HF fumes within the engine compartment and driver cabin on contact with fire.
*Non-conductive and non-harmful to electronics
Tested to be non-conductive at high voltages and certified safe for use on sensitive electrical/electronic equipment.
*No space requirements for pressurized gaseous agent tanks
Savings in space which can be used by driver for other purposes.
*No hazards (explosion) or maintenance (leakage) issues associated with pressurized gaseous agent tanks
The static aerosol unit is non-pressurized and certified for 15 years lifespan. Every unit is hermetically sealed and no maintenance on the unit itself is required. Placing a pressurized container within the driver cabin is a hazard to the driver in the event of a vehicle accident or failure of the cylinder valve.
*Fast reinstatement of fire suppression capability after discharge
Aerosol units can be easily and quickly (almost immediately) replaced whereas refilling of pressurized gaseous agent tanks will take a substantial time. And during the period agent refilling, the vehicle becomes unprotected.
Cost savings in maintenance and resources as all FirePro Aerosol units are sealed, and without any moving parts so only visual inspection (maintenance) of units is required.
*After discharge costs
After a discharge the aerosol units just need to be replaced. The cost of refilling pressurized gaseous agent systems are very high as the tank(s) need to be removed from the installation, sent to an off-site refilling station for refiling and then transported back to SPS site to be re-installed.
The FirePro Aerosol units have a certified lifespan of 15 years with a manufacturer’s warranty of functionality for 5 years. Typical warranty on pressurized gaseous agent systems are only 1 year, from the date of manufacture at the factory!
*Fail Safe Fire Suppression
In the event of heat detection system failure the system can be manual activated. If the fire is detected in the early stages, manual activation is possible to minimize any damage or contingencies. In the event of a fire within the engine compartment when the vessel is not running or not manned, the FirePro Aerosol units are designed to self-activate when subject to a 300°C temperature (fire) condition. This serves to prevent or mitigate the potential loss of the entire vessel.
*Banning of Chemical Agents
Many countries such as in the EU and in Australia, have already banned or restricted the use of chemical agents (so-called clean agents) such as FM200. The FirePro Aerosol system utilizes a natural mineral element that exists even in food ingredients and preparations.
*Simplicity and Flexibility
The Fire Aerosol units come in standard sizes. The number of units required for a hazard space is totally dependent on its volume. So in the event the vessel are replaced or upgraded, the FirePro aerosol units are potentially re-useable. All these have operational implications to the user. The Aerosol units can simply be dismantled along with the fire detection and control devices and re-installed in the new
