In January 2010, new regulations were introduced for engine manufacturers making it compulsory for them to reach Tier Two certification. Now, with the European Commission proposing a 20 per cent reduction in marine exhaust emissions on all recreational boats, some companies are raising the level even higher seeing innovation as the key to success.
Regulations require that manufacturers build machines compliant with the emission standards in effect at the time of manufacture, however one Korean company, Hyundai SeasAll, sees innovation and making the most of new technology as a key selling point. The company is still relatively new to the marine market but is determined to respond to consumer's demands for more affordable, more efficient and quieter running propulsion units for its vessels.
The exclusive UK and Ireland distributor for Hyundai SeasAll is WaterMota, whose sales director, David Dalgleish, explained: “New regulations were introduced last year compelling engine manufacturers to meet Tier Two certification however Hyundai SeasAll has gone even further with its new engines meeting Tier Three regulations and possibly being the most advanced engine of its type.
“The company’s engines use the latest technology from Hyundai-Kia automotive's advanced research centre - which happens to be on the same industrial campus where Hyundai SeasAll's headquarters and manufacturing is located – and its engines are designed to meet - and exceed - the latest environmental requirements in all world markets.”
He added: “Increasingly our customers are asking us what the fuel consumption of an engine is, more and more, they want fuel efficient engines whereas previously this question was hardly ever raised.
“Modern common rail engines typically use 15 per cent less fuel than three years ago. It’s an area where manufactures are making huge strides.”
To a great extent, the commercial side of our industry is being driven by wind farm work boats says David. They want compact, durable, lighter engines with higher output and most importantly fuel efficient, which will enable the boats to deliver personnel to and around the wind farms quickly
And he says the desire for low emissions and environmental pressures are other big driving factors.
“Modern technology is constantly moving on. Hyundai SeasAll as a company is very forward thinking and because its design technology is devised from that which has already been proven in the automobile industry the company can build on this and produce extremely advanced engines.”
A full electronic fuel management system and electronic unit injectors are necessary in order to meet current and future emissions requirements such as KST, RCE, MED SOLAS, BSO, CCNR and IMO. The engines can also be classified in order to meet the requirements of various classification societies for Type Approval.
The company, whose initial range consisted of two engine blocks in four different variants from 150hp-250hp, is in the process of launching two new engines – 125hp and 420hp – which will be on display at METS this November.
Ted Fagerburg, director of international operations, added: “While the H420 has been initially conceived for commercial operations, the characteristics of the engine are such that we have already received expressions of interest for several pleasure boat repower applications.”
And he explained that the H420 has been developed from advanced bus engines, which must operate in highly demanding duty cycles and meet strict emissions standards.
“Hyundai SeasAll has leveraged these attributes and built them into what we believe is the most advanced engine in its category. It is fully electronic which allows sophisticated combustion control for smooth running, outstanding fuel economy as well as real-time engine diagnostics via a helm-mounted Engine Operation Indicator to facilitate preventive maintenance. Both these new engines are highly sophisticated and really are best in class.”
Ted explained that the company is at the cutting-edge of marine engine technology, using sophisticated techniques to verify structural integrity, vibration and heat transfer of all key components from an initial design stage.
Durability has been achieved through innovations in more efficient and safer cooling circuits as well as a corrosion-resistant design.
The company also claims that its optimal engine combustion technology with CRDi produces the best fuel efficiency of its kind and says it is taking the lead in emissions ratings, which surpass even the strictest regulations.
Each engine is delivered with a smart self-diagnosis system and Engine Operating Indicator, which will diagnose and control, with an audio alarm and LCD display informing users of any problems.
Another manufacturer working hard on innovation is US generating and propulsion specialist, Westerbeke Corporation, which has been building engines, generator sets, air conditioner systems and other related marine accessories for more than 70 years.
Westerbeke was the first company to offer NMEA 2000 certified diesel generators several years ago and believes the future trend will be growing co-operation among more marine manufacturers offering NMEA 2000 certified products with huge growth potential possible with information sharing through the common protocol.
Cost, weight and space are reduced through NMEA 2000 with boat builders and private owners using Westerbeke’s D-NET generators, factory-fitted with NMEA 2000 data bus, able to wire their boats more efficiently with all NMEA 2000 certified components ‘plugging into’ a single cable integrating on board data communications.
This also simplifies the installation of most electronic components since there is no need to run bundles of wiring throughout a boat. For engine manufacturers such as Westerbeke and Hyundai SeasAll, innovation is seen as the key to success but for others such as Doosan, sticking with the tried and tested is all-important at present.
Paul Dancy, project manager at Manor Marine, explained: “We like the Doosan engine as it’s so reliable, robust and easy to maintain. It’s extremely good quality.
“Our customers are from countries around the world including Columbia and Nigeria who order work boats from us. Our customer is Desmi Ro-Clean, which has been supplying workboats for more than 25 years. Previously customers specified which engine they wanted so we had no room to manoeuvre but now we have more flexibility and try to steer customers towards Doosan.
“For a workboat the engines are ideal – our customers don’t want electronic controls and all the latest technology. They want to be sure they are getting the most reliable engine possible, which can be easily fixed if it does break down.
“Our first really big order was in November last year and since then we have bought 14 engines and placed an order for two more.”
According to David Dalgleish and his customers, Doosan marine engines provide great value for money – a good product and package. The company has mechanical injected engines, which still meet the latest emission regulation, and have been changing to meet emission standards for several years. However the emission laws will ensure that in early 2012 a range of Doosan engines will be moving across from the truck, bus and heavy plant side in to the marine division meeting Tier four and Euro four. Many Doosan models will go through as many as five different tiers of standards: Tiers one to three, Interim Tier four and Tier four.
David said: “This clean diesel technology will greatly reduce the levels of harmful emissions such as particulate matter (PM) and Nitrogen Oxides (NOx) that enter the air. The standards will help to improve air quality.”
Standards for diesel exhaust emissions have become more stringent from tier to tier with each tier addressing numerous types of pollutants with Particulate Matter (PM) and Nitrogen Oxides (NOx) receiving the most attention.WaterMota
