New Control Units Enter Service with Japanese Naval Fleet

March 1, 2017 / Alpharetta, Georgia

Vericor Power Systems has upgraded three Japanese Maritime Self Defense Force (JMSDF) LCAC craft with new and improved Full Authority Digital Electronic Control (FADEC) engine control units bringing added reliability, operational flexibility and enhanced maintainability to the fleet. The other three craft will receivetheir new units later this year.

The JMSDF LCAC craft are very similar to the US Navy versions. The US Navy craft began receiving new FADEC units in 2010 and Vericor has since delivered more than 270 units. “Our team has done a terrific job getting these units into service with the Japanese Navy where the benefits will be realized immediately” saidShannon Rogers, Vericor VP of Programs and Aftermarkets “The feedback from the three crafts in operation has been all positive”.

The new Vericor units are lighter and smaller than their predecessor units and bring a host of new features. Prominent among these features is improved load sharing between engines. Each LCAC craft has four Vericor gas turbines and in a drive train unique to this craft, the two engines on each side share load responsibility for both the large propulsion fans and the lift fans that inflate the craft’s cushion. With load sharing capability now designed in, the engines can do a much better job of allocating their power to these two load devices.

Another feature of this next generation control is a comprehensive diagnostic capability. The new design offers real time data monitoring and fault analysis. This improvement paid dividends immediately with the JMSDF when they were able to reduce routine trouble shooting that would have taken 8 hours to a few minutes. This ability will greatly enhance the operational readiness of the Japanese fleet.

The LCAC craft operate in one of the most arduous environments, in a virtual constant haze of sea salt and spray. The gas turbine engines that Vericor supplies are proven day in and day out in this challenging operating atmosphere. The new FADEC units will help the Vericor engines deliver their power more effectively and with even higher reliability.

Vericor Brings TF50F Gas Turbine to Offshore Technology Conference

May 02, 2016 / Alpharetta, Georgia

On the Vericor Power Systems stand at the Offshore Technology Conference in Houston this week will be a display version of the TF Series gas turbine, specifically aimed at the O&G market for pump, compression and portable power generation applications. Rated at over 5000 hp, the TF50F gas turbine is radically changing the process of hydraulic fracturing, making it cleaner and more cost effective.

The TF50F combines features from both of Vericor’s marine and industrial gas turbine product lines, making a gas turbine that is ideally suited for oil field applications, in particular, pump drive and electric power generation. Twenty years of service in one of the most demanding operating environments for a gas turbine, the US Navy, Landing Craft Air Cushion or LCAC, has given the TF series engines a reputation for toughness and reliability. Vericor considers these basic attributes a solid foundation for the demanding oil field job. The compact size of the TF engine which traces its roots to helicopter propulsion makes the engine perfect for mobile power whether it is for driving a hydraulic fracturing pump or creating electric power.

To adapt the TF to the rugged oil field application Vericor has revised some of the engine auxiliaries and their mounting locations, improving the engine’s adaptability to a trailer mounted power plant. The most significant addition is the ability of the engine to operate on both gas and liquid fuel, and to be able to change over from one fuel to the other while operating. This flexibility is a significant benefit to oil service operators. “This is engine will be a game changer in the oil field application. ”says Richard Clinton, Vericor President and CEO, “Packagers will find that the compact size of this engine is a very attractive alternative to larger and heavier diesel engines”. “In fact, there are several customers who are planning new pumping equipment built around this engine” he added.

As with all Vericor gas turbines, the TF50F is a two shaft, free power turbine engine and is designed to accept the high torque necessary for the hydraulic fracturing application. Extensive factory and field testing has already proven that the TF50F will deliver the required pumping power and operational flexibility for not only current 2500 hp pumps, but also the new 3000, 3500 and 5000 hp pumps that are being planned. The ability of a single TF50B to drive these larger pumps will change the whole dynamic of the frac spread. “We envision that an oil field operator can significantly reduce the amount of equipment at a single spread by using gas turbine engines in place of diesels” Clinton said. “And using treated well head gas, the TF50B gas turbine can significantly reduce the overall operating cost of a fracturing operation and demonstrate a very short payback period.”

Other applications of the gas turbine include gas compression and mobile power generation. The compact nature of the power plant is especially suited to single trailer packages for use in a wide variety of applications and markets. “A 3.5 MW single trailer portable power unit weighing less than 60,000 lbs is going to be attractive in a variety of operations” continued Clinton.

The Use of Well Head Gas as a Fuel for Fracing and Power Generation

September 01, 2015 / Alpharetta, Georgia

One of the principle costs and logistical challenges facing well service operators at a well site is the provision of fuel for the engines driving the equipment. In fact, fuel costs can account for 20% of well completion costs. Typically, liquid fuel such as diesel fuelis trucked in as needed. This results in significant cost, and both logistical and environment issues at the well head site. Now, with the abundance of natural gas from the very successful shale play exploration and production, operators have begun looking at using the natural gasbeing produced asfuel for the equipment located at remote sites. Early experience has shown that using well head natural gas can be advantageous over liquid fuel, even at today’s lower liquid fuel prices.

Diesel engines inject natural gas into the engine not via the fuel system, but rather by mixing it with the air entering the engine. Currently,the use of well head natural gas is limited by the ability of the diesel engine to operate in this bi-fuelmode.Excessive substitution rates can reduce the torque/power output of diesel engines. Liquid fuel substitution rates as high as 70% have been reported, however, a more representative substitution rate based on the total operating cycle is in the 50% range. One environmental concern with bi-fuel systems is a phenomenon called “methane slip” in which not all of the natural gas supplied to the engine is burned. The unburned natural gas is exhausted by the engine. Much concern has been voiced about the environmental effects of methane slip.

Vericor gas turbines are equipped to operate on either 100% liquid fuel or 100% natural gas, depending on the type of fuel available. The fuel is provided via the engine fuel system and therefore no fuel mixing is required. More importantly, Vericor gas turbinesare able to switch between liquid and gas fuel “on the fly” while operating under full load.Consequently,if there is an interruption with one fuel source,the gas turbine can be switched to the other fuel withoutdisrupting the hydraulic fracturing process. The changeover is completed automatically -no adjustments to the fuel system are needed. The unit simply changes the fuel source in a fully controlledmanner. The savings associated with burning 100% well head natural gas are compelling, especially in today’s challenging marketplace. The environmental benefits of eliminating liquid fuel are equally attractive. Since the natural gas is supplied through the normal fuel system, there is no methane slip associated with gas turbine operations.

As an alternative to using well head gas as the fuel source for the gas turbine, some operators have considered trucking inLiquified Natural Gas (LNG) or Compressed Natural Gas (CNG) to the well head sites. While this avoids the on-site fuel treatment process,the preferred approach is to treat well head natural gas in situ to avoid fuel transportation costs. Well head gas treatment is safe, proven and cost effective. In fact, some suppliers will treat well head gas on a fee per standard cubic foot basis. Another option used in some shale plays is to use gas from nearby pipelines to fuel hydraulic fracturing equipment.Each of these methods has its own advantages and disadvantages based on the conditions at the site. Analysis of these options by Well Service Providers is required to select the best option for a specific site.Regardless of any logistical issues, natural gas is quickly becoming the preferred fuel, displacing liquid fuel.

Using gas turbines powered by 100% well head natural gas for fracingnot only provides cost and environmental benefits, but also reduces the number of trailers required at a well site, allowing the size of the pad to be reduced.Vericor’s 5000 shp gas turbine provides twice the shp of a diesel engine typicallyused on frac trailers, is smaller in size, and doesn’t require a radiator. This results in low pad construction and remediation costs as well as lower personnel needs. Similarly, the weight and size of the equipment to be moved is reduced resulting inthe elimination of roadpermits and escorts between sites.Logistical problems are reduced considerably. Furthermore,gas turbines operating on well head gas deliver long term maintenance cost advantages compared to their diesel or spark ignited engine counterparts.

In summary, using wellhead gas as fuel provides many advantages to the equipment operator over the traditional liquid fueled diesel engine. These advantages can be summarized as: significantly lower fuel costs, no methane slip, smaller well pads, fewer personnel and lower maintenance costs. In today’s challenging cost-competitive environment, well head natural gas usage is seen as a competitive necessity by technology leading companies.

Tech Talk from Vericor: Gas Turbines in Cogeneration

April 01, 2015 / Alpharetta, Georgia

tech_talkbig Cogeneration is an attractive energy producing alternative to grid power when the facility also requires heat for the process being performed. Using gas turbines as the prime mover to generate electrical power provides opportunities for improving energy utilization, efficiency, reliability, and in many cases, process operations using the exhaust heat of the gas turbine.

Recovering Useful Heat

Over two-thirds of a gas turbine generator’s energy content is converted to waste heat. By recovering the heat for productive use in other processes, efficiencies are improved from nearly 30 percent to over 80 percent, depending on the application. Furthermore, the recovered heat is often better than free when heat recovery equipment displaces a boiler or other heating source, resulting in a net reduction in fuel expenses and emissions.

The objectives of installing a cogeneration plant are to meet both an electrical power demand and a prescribed heat load. Typically, the facility heat load is the most critical parameter to match despite the obvious task of generating electricity. Since heat load must be satisfied using a constant stream of exhaust gas, a thorough understanding of the heating load profile and the ability to match the heat load at any given time are critical.

Variations in heat load are accommodated through an exhaust bypass for low load factors and supplemental firing for high load factors. Alternatively, the electrical demand can be easily supplemented by the utility company during power shortfalls or resold to the utility company during low electrical demand. Economics favor systems that operate at least 8,000 hours per year and that have sufficient and constant heat loads.

Cogeneration Advantages

Power reliability: Onsite cogeneration systems equipped with sufficient redundancy such as standby grid connection and Uninterruptible Power Supply (UPS) systems can far exceed the reliability of some local utilities.

Power quality: Gas turbine generators typically provide constant voltages and currents without the external peaks and interruptions that are often found on the grid.

Reduced emissions: Compared to supplying heat and power loads separately, cogeneration offsets other forms of energy production such as power grid generation and localized firing of natural gas or diesel in a boiler for steam production.

System Alternatives

The application of cogeneration to various processes is boundless. As long as a significant heat sink is available, economics and imagination are the only limiting factors. Some examples include:

  • Mix air with gas turbine exhaust as a means to direct dry various products.
  • Direct the gas turbine exhaust into an indirect-fired absorption chiller to produce chilled water.
  • Heat or vaporize heat transfer fluids other than water for chemical process applications.
  • Apply cogeneration to a large scale building energy plants where power, steam, hot water, and chilled water are produced from a single fuel source.
  • Connect a backpressure steam turbine with an overriding clutch to the free end of the generator in a gas turbine generator package.

Cogeneration has potential in almost every industrial and commercial setting. By evaluating the power and heat costs paid over the life cycle of a plant, it becomes obvious that the economic and operational benefits far outweigh the effort of developing and maintaining a cogeneration plant.

Vericor TF50F Gas Turbine Powers Successful Field Test of 4500 HHP Frac Pump

February 10, 2015 / Alpharetta, Georgia

Vericor Power Systems is pleased to announce the successful field testing of a TF50F gas turbine powering a 4500HHP fracturing pump. The Vericor TF50F gas turbine, specifically designed for the fracturing application, demonstrated the ability to drive the stimulation pump and do so in conjunction with a conventional diesel engine equipment spread. Rick Clinton, Vericor President and CEO said “This achievement clearly validates the TF50F’s ability to dramatically reduce the cost and environmental impact of hydraulic fracturing. This is a true game changer.”

The 5000 HP TF50F gas turbine reduces the number of trucks at a well site by up to 50 percent. Its ability to burn 100% well head gas eliminates the need for diesel fuel to be trucked to the well site. And, the TF50F’s free power turbine design eliminates the need for a transmission. These innovations result in smaller well pads, dramatic fuel savings and fewer personnel.

Vericor Launches TF50F Oil Field Gas Turbine

January 1, 2015 / Alpharetta, Georgia

Vericor Power Systems announced today a new version of the TF Series gas turbine specifically developed for hydraulic fracturing applications. Rated at 5,000 hp, the TF50F combines features and benefits from Vericor’s proven marine and industrial engine product lines for oil field pump drive and electric power generation applications.

With twenty years of demanding service in the US Navy Landing Craft Air Cushion or LCAC, the TF series engine has earned a reputation for toughness and reliability – a requirement of oil field service.

The compact size of the TF engine, which traces its roots to helicopter propulsion, reduces the footprint and increases mobility for generation and hydraulic fracturing equipment.

The TF50F can operate on both gaseous and liquid fuel, make the changeover under power and operate 100% on well head gas while meeting all Tier 4 emission requirements.

“This is really a game changer ”says Richard Clinton, Vericor President and CEO, “The TF50F will offer producers and well service operators cost savings of over 80% vs. larger and heavier diesel engines”.

As with all Vericor gas turbines, the TF50F is a two shaft, free turbine engine and is designed to accept a high torque application such as hydraulic fracturing pump drives. The free turbine design means that only a speed reduction gearbox is required, eliminating the need for a transmission which is often a reliability issue in most operations. Extensive testing verified that the power section will deliver the required pumping torque and operational flexibility for not only current 2500 hp pumps, but also for the next generation of larger pumps.

“We envision that an oil field operator can significantly reduce the amount of equipment at a single spread by using gas turbine engines in place of diesels” Clinton said. “In fact, we see a single TF engine replacing two diesel driven pumps, reducing the amount of machinery in a frac spread and giving oil service operators a whole new game plan”.
