Caterpillar has been selected to provide gensets for the Asian Gas Pipeline, a joint project between Kazakhstan and China which will deliver a total of 2 per cent of China’s energy consumption.
Caterpillar will provide six G3516C gas generator sets and two C18 generator sets. Each G3516C generator set will provide the gas compression stations with 1555 ekW (1944 kVA) of rated power at 1500 RPM. The C18 generator sets will be utilized as emergency backup power for the gas compression stations.
Once completed, the Asian Gas Pipeline will transport 30 billion m3 of natural gas from Turkmenistan to China and 10 billion m3 of natural gas from Kazakhstan to China per year.
Construction of the pipeline started in July 2008 and is due to complete in late 2013 or early 2014. The total length of the 42 inch pipeline, which is carried in two lines, will exceed 6500 km: 200 km in Turkmenistan, 510.5 km in Uzbekistan, 1300 km in Kazakhstan and 4500 km in China.
“The G3516C is the industry standard in land production power, designed to provide maximum annual operating hours, plus continuous power quality even with variable loads,” said Mikhail Potekhin, Caterpillar Global Petroleum CIS sales manager.
“A lean burn engine, the G3516C features an open-chamber engine design that operates on a low-pressure gas system of only 35 to 350 millibar pressure (0.5 to 5 psi) while delivering 41.8 per cent mechanical efficiency.
Engine control is managed by the ADEM A3 system, which provides a single source for full engine control of air-to-fuel ratio, engine governing, ignition timing and detonation protection and system communications. Additionally, the G3516C features advanced island mode control, which monitors the generator’s electrical output to ensure high power quality and superior load acceptance.”
Jonathan Scholefield, Caterpillar Global Petroleum CIS & EAME regional sales manager, described the G3516C as the ideal engine for the land production power industry through offering the greatest return on investment.
“By lowering fuel consumption and increasing workforce efficiencies, the engine is able to increase the intervals between maintenance and consequently lower overall operating costs,” he said.
The G3516C generator sets were shipped from the Caterpillar factory in Lafayette, Indiana, United States in July 2011. The C18 generator sets are being supplied from the inventory of Caterpillar Dealer Borusan Makina. The gas compression stations powered by Caterpillar generator sets are scheduled for start-up from September to November 2011.

RSS supplies 19 000TR cooling in Abu Dhabi
Demand in the UAE’s capital city Abu Dhabi has soared with its economic recovery and a diversification from petroleum-related projects. Summer temperatures of as high as 50 à‚°C trigger peak demand between May and September for rental chillers, air handling units, DX units, and other cooling equipment.
“Since RSS started its operations in Dubai and Abu Dhabi, we have achieved rental breakthrough records for installing the biggest temporary cooling package in the world, the largest rental chiller installation into a single header connection point, the largest chiller hire contract and largest rental cooling supplier for the transportation sector,” said Milan Balac, managing director of Rental Solutions & Services.
RSS currently supplies temporary chiller installations and temperature control applications to two hospitals, Abu Dhabi’s largest mall, the capital’s largest sports city, sea-going vessels, aircraft hangars and more than 20 high rise towers, said Lee Cox, general manager of RSS Southern Gulf.
“RSS is also supplementing the cooling supply of the three largest district cooling companies in Abu Dhabi during construction stage of their DC plants,” he added.
Temporary generators ease Cyprus power crisis
Temporary power generators from overseas along with efforts to repair destroyed power supplies are helping meet Cyprus’s electricity demand after the 11 July Vassilikos power station blast took 60 per cent of supply offline in July. A first batch of generators from the Greek Public Power Corporation were put into operation on 8 August, reported the Famagusta Gazette.
A further batch of generators with total capacity of 70 MW will be brought from Greece on 31 August while 95 MW will come from US company Energy International, said Giorgos Siammas, president of the Energy Regulatory Authority (CERA).
Generators leased from Energy International Limited will be installed in Dhekelia and Moni power stations. Electricity Authority of Cyprus (EAC) and Energy International have signed a contract for the supply, installation, operation and maintenance of temporary production units. The production units of 95 MW are expected to arrive in Cyprus on 15 August and to operate by the beginning of September.
Siammas said that by the end of August, a unit at Vassilikos power plant will be repaired, which could produce additional 35 MW.
He added that electricity production is being enhanced by generators totaling 12 MW from Israel. Another 20 MW will be supplied by generators offered by the Bank of Cyprus ” 10 MW to cover the Authority’s needs and 10 MW for Bank of Cyprus needs.
Cummins mechanical B3.3 engine moves towards Tier 4 with new aftertreatment
Cummins Inc has announced its mechanical B3.3 engine will move forward to meet Tier 4 Final emissions standards in 2013 with a particulate filter aftertreatment system developed specifically for use in compact equipment rated below 75 hp (56 kW).
The new exhaust aftertreatment operates as an independent system to achieve near-zero particulate matter (PM) emissions, enabling the B3.3 to simply “up-tier” to Tier 4 Final without the need for any change to the engine.
Using a particulate filter-only solution for Tier 4 Final means that the B3.3 engine maintains exactly the same class-leading performance and reliability that it achieves today at Tier 4 Interim emissions levels, said Cummins. The inherent simplicity of the mechanically controlled 3.3 litre engine continues forward without adding either engine electronics or changing the fuel system.
The ability of the B3.3 to easily up-tier with the particulate filter provides a more efficient installation solution by retaining the same engine configuration for use at all emissions levels worldwide across the important 55″74 hp (41″55 kW) power range for compact equipment.
The particulate filter has been developed by Cummins Emission Solutions to meet the EPA Tier 4 Final and equivalent emissions standards in Europe and Japan taking effect on 1 January 2013 for engines below 56 kW. The aftertreatment reduces PM emissions by over 90 per cent to a near-zero level of 0.02 g/kWh for machines such as excavators, aerial lifts, forklifts, tractors, gensets and skid steer loaders as well as other compact equipment.
“Cummins up-tier solution for the B3.3 to meet Tier 4 Final is unique in the industry, with the new particulate filter replacing the exhaust muffler and with no change to the proven mechanical engine platform,” said Chris Calas, Cummins 3.3 litre product manager.
“With only one B3.3 engine configuration required for all markets worldwide, this means that equipment manufacturers will benefit from more streamlined production and easier in-service support.
“The machine cooling system remains the same for all emissions standards, with no additional heat rejection and additionally no need for engine aftercooling.”
MTU Onsite Energy supplies gensets for emergency power in Japan
Tognum Group subsidiary MTU Onsite Energy Corporation has provided 43 generator sets to Japan as part of a 203 MW emergency power contract formed between Tokyo Electric Power Company (Tepco) and APR Energy.
APR, headquartered in Jacksonville, FL specializes in the rapid global deployment of custom turnkey power solutions that utilize both diesel and gas turbine technologies. The generator sets powered by MTU 16V 4000 diesel engines were assembled at the MTU Onsite Energy facility in Mankato, MN and then containerized before their journey to Japan.
In the wake of Japan’s recent earthquake and tsunami, these emergency power plants supplied by APR will provide additional electricity to the cities of Yokosuka and Hitachinaka, both on Japan’s eastern shore where much of the damage occurred. The two power generation sites successfully started up in July of this year.
“We are pleased to take part in this emergency power project for Japan by supplying our containerized diesel generator sets to APR Energy,” said Christof von Branconi, Tognum COO with responsibility for the business unit Onsite Energy & Components.
“Containerized diesel generators’ advantages include quick deployment and easy installation as well as great fuel efficiency. They will complement the project’s gas turbine generators by adding operational flexibility.”
The MTU Onsite Energy Series 4000 generator features Advanced Diesel Engine Control system and 20 per cent more cubic inches of cylinder displacement than other generator drive engines. This increase results in more reserve horsepower and torque, while delivering excellent fuel economy.
