Wärtsilä grows global service offer
Wärtsilä is expanding its global service workshop offering in turbocharger services.
Over 20 Wärtsilä service workshops globally are equipped with full capability to service turbochargers. With this investment, Wärtsilä is able to offer customers global turbocharger services coupled with engine knowhow in flexible cooperation with other Wärtsilä service centres. Customers can reduce their operational risk and save time by being able to overhaul the turbocharger at the same time as the engine.
Wärtsilä has to date made a significant investment in over 20 turbocharger service workshops globally with full capability to service turbochargers. The specialised workshops are equipped with modern tools and equipment for turbocharger maintenance and are capable of performing a wide range of turbocharger service work.
Specialised and certified service engineers are trained for turbocharger overhauls both at workshops and on-site. Wärtsilä's specialised turbocharger workshops operate in close co-operation with global service centres, providing assistance in troubleshooting, maintenance, upgrades and replacements. For customers, this means increased flexibility, reduced operational risks and savings in time and costs, since they have the possibility to overhaul the turbocharger at the same time with the engine.
In March, Wärtsilä opened the most recent renewed service workshop in Schiedam, Netherlands. Other turbocharger workshops include for example Fort Lauderdale, USA; Quito, Ecuador; Gaziantep and Istanbul, Turkey; Dubai, UAE; Mumbai, India and Jakarta, Indonesia. These workshops operate flexibly with each other and other Wärtsilä service centres, allowing customers to have expert service at short notice. Similarly, turbocharger service workshops will be linked to other Wärtsilä service centres in other areas as well.
"With this investment, Wärtsilä strives to offer comprehensive services that enable the best performance of customers' assets. By offering complete turbocharger services closely coupled with the engine maintenance expertise, we can apply a holistic approach that optimises maintenance operations across the equipment. We have received good initial feedback from our customers. Our customers value our flexible one-stop-shop service model, which allows them to gain significant cost savings," says Tomas Hakala, vice president, four-stroke engine services, Wärtsilä.
Mitsui expands co-operation with MAN
MAN Diesel & Turbo has entered a comprehensive cooperation agreement with Mitsui Engineering & Shipbuilding Co., Ltd. that will intensify their existing, joint business activities. The agreement was signed by Takao Tanaka, President & CEO of Mitsui Engineering & Shipbuilding and Dr. Uwe Lauber, CEO of MAN Diesel & Turbo. “Together, we will offer a solution portfolio that is unique in today’s market,” said Dr. Lauber.
The two companies are longstanding partners, with multiple previous collaborations, and have now agreed to to deepen mutual activities within – initially – sales, production, R&D, and EPC (engineering, procurement, construction), with the potential for other business fields to be added in the future. The common goal is to enhance mutual business opportunities in a more timely and effective fashion.
“Mitsui Engineering & Shipbuilding and MAN Diesel & Turbo can look back at almost a century of successful cooperation in many fields of business, for example, two- and four-stroke engines for marine and stationary applications”, said Tanaka. “With this agreement, we not only consolidate these cooperative efforts, but we also extend them to include the steam turbine and compressor segment.”
“Along with the ongoing implementation of our technology in power plants and marine projects, we have also agreed to set a greater focus on our joint R&D efforts,” said Dr. Lauber. “Driven by the global trends of decarbonisation and digitalization, markets are in transition. We want to continue to combine our strengths to offer propulsion and energy solutions that help our customers to tackle tomorrow’s challenges. This will also include working more closely in the field of Floating Production Storage and Offloading systems (FPSO), as well as steam turbines and compressors – mainly for the Japanese market.”
MES is the longest-standing of MAN’s licensees.
Caterpillar adds turbocharged diesel
Caterpillar has added a new, tubocharged diesel to its range that promises to offer a high power density combined with fast acceleration and quiet operation.
Called the C7.1 this new engine is a 6 cylinder unit that takes this manufacturer firmly into the high performance market.
As a marine propulsion engine, it is available in three ratings that can meet a variety of applications. The high-performance version will produce 373 kW, while the lowest power version offers 298 kW. In between is the 336 kW engine and unusually, all of these power outputs are achieved at the same 2900rpm. All of the C7.1 power ratings on offer meet the EPA Tier 3, the IMO II, the EU Recreational Craft Directive and EU Stage IIIA emission regulations.
"The new turbocharged C7.1 platform is a powerful, compact addition to our high performance product portfolio," said Charlson Smith, the Caterpillar Marine sales manager. "The engine offers a superior power to weight ratio, resulting in a swift response time and speedy acceleration."
The C7.1 is a 6 cylinder in line four-stroke diesel with turbo-charging and after-cooling. The displacement is 7.1 litres and the engine features a common rail fuel system enabling optimum combustion and low emissions.
The dimensions of the C7.1 are a length of 1394mm, a width of 798mm and a height of 876mm. The dry weight of the engine is 750.0kg. There is a wide range of standard equipment on the engine including an air cleaner, watercooling of the turbocharger and a condensate drain on the after-cooler. There is a cold start strategy incorporated into the control system and full engine diagnostics and fault logging. The engine can accept three types of throttle inputs that cover most control systems and there is a 70 pin customer connector.
MTU engines include turbocharger enhancements
Rolls-Royce Power Systems’ MTU-branded engines include a number of turbocharging enhancements.
MTU's new 16-cylinder gas engine is based on the tried-and-tested MTU 16V 4000 M63 workboat diesel and will be marketed with a power range of 1,500 to 2,000 kW from 2018. An 8-cylinder version is to follow, with a power range of 750 to 1,000 kW.
The new gas engine is especially well-suited to tugboats, ferries, push boats and special purpose vessels such as research craft.
MTU gas engines come with multi-point gas injection, variable combustion pressure control and improved turbocharging. The combustion design concept ensures efficient use of fuel and enables IMO III emission standards to be met without additional exhaust aftertreatment. A compact, built-on oxidising catalytic converter (oxi-cat) is used to achieve EPA Tier 4 standards. The jacketed design allows the engine room to be fitted out in the same way as for a diesel engine.
The Series 4000 technology package includes high-pressure common rail fuel injection and two-stage turbocharging with adjustable high-pressure stage and exhaust gas recirculation. Together, these technologies deliver very low-particulate and low-nitrogen oxide (NOX) emissions – without requiring aftertreatment, additives or related infrastructure.
