GENSET FOCUS

New offshore rental gensets set to launch

Mobile power solutions firm Bredenoord and offshore genset supplier DBR are set to release a new range of marine and offshore certified rental gensets early this year.

The machinery has been designed specifically for offshore deployment, complies with the IMO Tier II emissions regulations, and is designed to meet the IACS, SOLAS and NORSOK requirements, the two firms said. In addition, the generators are containerized according DNV2.7-1 regulations for offshore lifting.

The new fleet represents a joint project, with DBR building the machinery and Bredenoord providing installation.

The gensets are designed for use in harsh environments and under heavy-duty conditions, the companies said, adding that they can be deployed safely in the marine and offshore, wind energy and petrochemical sectors without adjustments.

Genset order for Italian district heating

Italian utility Hera SpA has ordered two 3.9 MW generator sets for its new district heating facility in Bologna.

The order for the CX501-KB5 gensets from Centrax will help Hera provide its customers with hot water using a combined heat and power (CHP) system. Centrax will supply a hot water boiler, attenuator and exhaust stack per turbine which will form part of the district heating scheme.

CHP capability, low emissions and low noise (due to the plant being close to residential areas) were important criteria for the gensets, Centrax said.

Centrax’s European sales manager, Toby Boys, said: ‘We’re delighted to have worked with Hera SpA throughout this project and Centrax looks forward to continuing the support throughout the servicing contract. The units will be serviced from our Italian depot situated just an hour’s drive away from the site.’

The units are due to be delivered early in the year and, according to Centrax, will bring the total number sold in Italy to 20.

Kohler introduces new gas generator line

US-based Kohler Power Systems has announced the launch of a new natural gas-fired generator range designed for standby, prime or continuous power applications in the North American market.

The new line of large gas gensets will be available in models ranging from 425 kW to 1300 kW, the firm said, and will meet US Environmental Protection Agency (EPA) operational requirements as well as offer advanced control and monitoring capabilities through a digital controller.

The gensets can run on natural gas as well as a wide variety of non-pipeline gases, Kohler said. The company collaborated with Dresser-Rand to create specially tuned engines for the genset market. It said the 1800 rpm engines accept a wide range of input fuels and resist fuel contamination.

‘We anticipate a strong response to our new large gas line because each model is targeted to fit the exact needs of the end user,’ said Nolan Landes, senior product manager for Kohler Power Systems. ‘Unlike manufacturers who offer a continuous power generator for use in prime and standby applications, our generators are designed to work specifically for continuous, prime or standby applications.’

ABB launches 4-pole generators for turbines

ABB has launched a new 1400 frame size synchronous generator to expand its AMS platform.

The new 4-pole generators will cover the power range from 60 MVA to 85 MVA at voltages from 3 kV to 15 kV. The company said the higher power levels mean end users will require fewer genset units, minimizing space needs and capital investment and enabling more economical genset designs.

In addition, ABB said the 4-pole generators offer benefits over larger 2-pole models, including compact size, lower weight, better efficiency, higher inertia, shorter delivery time, lower running costs and simplified maintenance.

According to ABB, 4-pole generators are more reliable in start-stop mode as they operate below the critical vibration speed area, unlike 2-pole generators which must always run through it on every start.

And the firm said the new 1400 frame size generators will enable OEMs to increase the power in hot environments where, previously, the need for de-rating could mean that the required output exceeded the 4-pole range.

New Doosan generators designed for EU emissions requirements

Doosan Portable Power has announced the launch of two new generators that meet EU Stage IIA emissions requirements.

The company’s 400 kVA G400-IIIA and 500 kVA G500-IIIA generators are designed for prime power applications. Doosan said both models were redesigned to meet the emissions regulations as well as to offer a wider choice of features applicable to temporary power needs.

According to Doosan, the generators’ output performance stability is ensured by an optimized powertrain that features a combination of Scania Stage IIIA engines and Leroy Somer alternators. The firm added that the use of variable speed radiator fans has improved fuel efficiency for both models.

The generators have a standard fuel storage capacity of a minimum of 10 hours of autonomous operation (at 75% load), while a 24-hour on-board fuel tank configuration is available as an option.

The fuel tank frame assembly ensures 110% fluid containment capacity. It provides the highest operational flexibility available in the generator market, Doosan claims, noting that as fuel quality and storage are the main concerns for rental companies, routine fuel tank maintenance tasks have been simplified, with special attention to the fuel tank cleaning and port draining processes.

The generators use Leroy Somer alternators with the AREP excitation system, which Doosan says is ideal for powering concrete and asphalt batching plants, major events or concerts, industrial processes and other applications with high load startup demands. To increase long-term reliability in harsh environments, the standard alternator configuration includes heavy-duty protection for the rotor and stator windings.

To increase flexibility, the two models will be available with an optional synchronization controller. Doosan said this option, which features the recently released DEIF AGC4 module and a Schneider motorized circuit breaker, will allow a generator unit to safely run synchronized with other units or the transport/distribution grid, in multiple application configurations.

MTU genset deal for Turkish hospitals

MTU Onsite Energy diesel gensets are to supply emergency backup power to a total of 35 health campuses in Turkey by the end of 2018.

With a combined capacity of 56 MW of standby power, Rolls-Royce subsidiary MTU has already supplied 10 units of the 16-cylinder Series 4000 diesel genset and one eight-cylinder Series 1600 unit to the Turkish medical institutions.

Under the deal with the Turkish Ministry of Health in Mersin and Bilkent, the engines have been supplied to the DIA Holding construction company for Mersin (located in the south of Turkey). A further 14 of the 16-cylinder and five 12-cylinder Series 4000 units will be shipped to Bilkent, near Ankara, in February.

A power requirement of 20 MW – 30 MW diesel genset output has been calculated for each project.

Turkish law states that power supply to hospitals in the country must be provided with 100% backup by emergency gensets.

‘The health sector is a priority in Turkey, as recent major investments have shown. The preference being given to at this early stage demonstrates trust in this brand and is a good sign for upcoming projects,’ said Ekrem Kuraloglu, Managing Director of MTU Turkey.

Hipower gensets use Waukesha gas engines

North America’s HiPower Systems has developed two new gensets using GE Distributed Power’s Waukesha gas engines.

The engines will debut in HiPower’s 313 kW HRNG-400 and 410 kW HRNG-510 gas-fired generators, the firm said.

For the HRNG-400, HiPower is using the 400 BHP, 1800 rpm Waukesha F18SE-EPA engine. The HRNG-510 will be driven by the 530 BHP, 1800 rpm Waukesha H24SE-EPA. Both engines will be certified by the US Environmental Protection Agency (EPA) for use in portable and stationary generator sets and other mobile equipment.

Bill Balough, business development executive for Waukesha Pearce Industries, the US Waukesha distributor, said both engines can run on fuel ranging from pipeline-quality gas to propane with minimal derate, and on most well-head gases without the need for extensive fuel conditioning or filtering.

‘For decades, by-product gas has been a challenge for oil and gas operators because the fuel required significant pre-treatment before it could be burned in the average generator,’ said HiPower’s president, Rafael Acosta. ‘Debuting a generator with an EPA-certified engine that has variable fuel capabilities greatly expands the options for burning wellhead gas-and extends the flexibility of the generators that use them.’

Finning in 15-genset contract

‘Further, rising numbers of tourists have resulted in the construction of new hotels and malls, which are depending heavily on diesel gensets. Additionally, these provide a backup power source in case of any power failure.’

One major trend the firm has seen is the growth of the rental genset market. ‘Real estate companies deploy gensets on a rental basis at construction sites to reduce the burden of high purchasing cost,’ Mani said.

Major players in Saudi Arabia’s diesel genset market include Saudi Diesel Equipment, Cummins, Caterpillar, Himoinsa Power, Atlas Copco and Kirloskar.

Caterpillar launches 570 kVA mobile genset for North America

Caterpillar has launched its CatXQ570 rental diesel genset, which it says is engineered to meet US Tier 4 Final emissions standards.

The mobile gensets are rated for prime power at 570 kVA or 625 kVA standby at 60 Hz. Caterpillar says they are designed for improved portability and noise levels and highly efficient voltage changes.

The new model is powered by the four-stroke Cat C18 ATAAC industrial diesel engine and is targeted at the mid-sized rental power market in the US and Canada.

Newly integrated into the unit’s control panel is an integrated voltage regulator (IVR) for control of voltage transients when the load varies. A transient load relief (TLR) system is also included, which Caterpillar says can improve the unit’s response to changes in load.

The gensets also feature diesel particulate filters, which Caterpillar says compare favourably to engines that use a SCR-only system.
