Engine started..

Weren't they supposed to switch the boilers to diesel? Looks like the same mazut spewing crap as before.

They are diesel. You just dont understand how a compression ignition engine works yet find it more convenient to mouth of BS.

I don't? I know that the higher quality diesel engines are supposed to be cleaner than the messy burning mazut it replaced. You didn't even know what it was.

Correct, read a bit about why a diesel produces a lot of smoke when started. And yeah, dont expect common rail direct injection engines on an AC man.

and what did I not know? that it was running on a diesel engine?

 

[trackwhack]

Here you go genius. Google saves your lazy ass.

Why do diesels blow a billow of black smoke when the accelerator is floored?
the soot is unburned carbon compounds. this can happen due to a change to larger injectors or just regular wear on the engine. it happens mostly in colder temperatures due to the fuel not being full combusted. example - when you are starting a cold engine.

now why it happens, you will have to learn the theory behin compression ignition engines.

Also in newer engines the first few times an engine is run you generally have a lot of extra smoke generated, due to impurities like dust etc being present inside the fuel lines and cylinders , also paint on the cylinder heads generally burns and evaporates along with any stil remaining traces of packaging on the same, i had the same issue with two new caterpillar 2000KVA DG's i got installed in January 2009, we got a lot of black smoke for the first two three times we ran the engines

INS Vikramaditya all set for crucial, pre-induction trials

Aircraft carrier will be delivered to India on Navy Day, December 4

The Sevmash chief would not discuss the refurbishment cost, but the media usually give $615 million as the initial contract price and $2.2 billion as the final price. However, Russian sources have pointed out that 25 per cent of that sum was the cost of training Indian personnel and building onshore infrastructure in India, and another 10 per cent was for additional systems New Delhi wanted installed when the contract was being renegotiated.

Mr. Dyachkov said Sevmash could have cut the cost by using cheaper materials and equipment but it rejected the option.

"Our top priority was to ensure irreproachable quality, reliability and long service life for the vessel. In fact, the shipyard did not make much profit on this contract, as most of the contract cost went to the suppliers of equipment and systems."

More than 400 subcontractors were involved in the project, including 10 Indian companies which supplied communication systems, protective coating, a telephone exchange, life rafts, pumps, hygiene and galley equipment, and many more.

Whatever you said regarding modern smokeless diesel engines is absolutely correct. That would be for engines like that of the VolksWagen Golf.

Vikramaditya is a different beast altogether. Relax, it won't be spewing so much soot forever.

INS Vikramaditya first sea trial set for Jun. 8 | idrw.org

NS Vikramaditya will take to the sea for crucial pre-induction trials on June 8, Russian shipbuilding sources said.

Last month, the trials were put off by two weeks due to bad weather alerts.

However, the delay will not affect the scheduled delivery of the aircraft carrier to the Indian Navy in December, according to the Sevmash shipyard, where the Soviet-era Admiral Gorshkov carrier has undergone modernisation and repairs.

"We are confident that we will hand over the vessel to India on December 4, Navy Day," said Sevmash Director-General Andrei Dyachkov.

The towering 45,300-tonne, 284 metre-long Vikramaditya stood moored at Sevmash when this writer, first foreign correspondent allowed on board, visited the vessel last week. The ship, rich with the smell of freshly painted walls and equipment, was bustling with pre-trial activity as workers took advantage of the postponement to put finishing touches to the 2,700 compartments of the 60-metre tall carrier.

The Sevmash chief was visibly proud of the work his shipyard did in converting the Gorshkov heavy carrier/cruiser into a full-fledged aircraft carrier.

'As good as modern vessel'

"Vikramaditya is as good as any new modern-day aircraft carrier," Mr Dyachkov told The Hindu in his first interview to a foreign newspaper. "Given proper maintenance, it will stay in service for up to 40 years."

Mr. Dyachkov is aware of bad blood in India over the huge cost escalation but says the price review was inevitable.

"When we opened up the equipment we realised that the scope of work would be far bigger than [what] the original contract envisaged. Most equipment had to be replaced and the ship was completely rewired with 2,400 kilometres of new cables," he said. "Never before has an aircraft carrier undergone such massive modernisation."

The Sevmash chief would not discuss the refurbishment cost, but the media usually give $615 million as the initial contract price and $2.2 billion as the final price. However, Russian sources have pointed out that 25 per cent of that sum was the cost of training Indian personnel and building onshore infrastructure in India, and another 10 per cent was for additional systems New Delhi wanted installed when the contract was being renegotiated.

Mr. Dyachkov said Sevmash could have cut the cost by using cheaper materials and equipment but it rejected the option.

"Our top priority was to ensure irreproachable quality, reliability and long service life for the vessel. In fact, the shipyard did not make much profit on this contract, as most of the contract cost went to the suppliers of equipment and systems."

More than 400 subcontractors were involved in the project, including 10 Indian companies which supplied communication systems, protective coating, a telephone exchange, life rafts, pumps, hygiene and galley equipment, and many more.

Extensive remodelling

Designed to operate only vertical takeoff aircraft, the ship has been extensively remodelled. It has had its flight deck extended and turned into a full runway with a ski jump and arrestor wires. The vessel has new engines, new boilers, new generators, electrical machinery, communication systems and distillation plants.

With INS Vikramaditya overhaul practically over, Sevmash is now focussed on carrying forward cooperation with India in the sphere of aircraft carriers.

"We are in talks with several Indian companies for setting up a joint venture to provide the full range of post-guarantee maintenance and repair services to INS Vikramaditya, including the supply of spares," said Mr. Dyachkov.

Sevmash, which has built more than 200 submarines and surface ships over its 70-odd years' history, is also keen on taking part in the construction of India's indigenous aircraft carriers.

"We have amassed invaluable experience in decades-long collaboration with Indian shipbuilders, which has been further enriched during the retrofitting of Gorshkov and modernisation of Kilo-class INS submarines," said Mr. Dyachkov.

Fire in INS Vikramaditya Not Delays Sea Trials

Fire happened to Indian aircraft carrier INS Vikramaditya (former Russian cruiser Admiral Gorshkov) retrofitted by defense shipyard Sevmash in Severodvinsk "by no means will affect the ship's gearing up for sea trials", the yard's press secretary Anastasia Nikitinskaya told ITAR-TASS.

According to her, "a fumigation of technical insulation occurred on June 1 and was eliminated in five minutes". "In full accordance with regulations, all people were evacuated from smoke-filled premises, and fire brigades were called, but there was no need for them", explained Mrs. Nikitinskaya.

Other sources say the fire outbreak happened in 1-st boiler room at 5:17 pm on June 1. Five fire trucks were dispatched to the carrier. Nobody suffered.

INS Vikramaditya was supposed to take the sea for the first time on May 25; however, Russian Navy Commander-in-Chief postponed that date for unknown reasons.

At the trials Indian crew will be assisted by 350 Russian mariners and shipyard's experts, totally over 2,000 men. All cabins and quarters are prepared to accommodate them; totally, there are 2,350 premises in the ship. Sea trials of INS Vikramaditya will be held in the Barents Sea during the first 2 or 3 weeks. Then will start the 3.5-month long tests of aircraft-related systems. The carrier's delivery deadline is Dec 4, 2012.

According to intergovernmental package agreement tied between Russia and India in Jan 2004, hull of Russian aircraft-carrying cruiser Admiral Gorshkov was handed over to India, given that the ship would be upgraded by Sevmash shipyard and equipped with Russian-made air wing. In addition, Russia committed itself to train about 1,500 Indian crewmen and build the ship's basing infrastructure in the Indian Ocean.

Overall value of the contract was initially estimated as $1.5 bln; it was planned to complete all refitting works in 2008. However, the deadlines were postponed many times. Russian party said the scope of works was undervalued and asked for additional financing for the ship's modernization. On March 12, 2010, when then-premier Putin was visiting India, the parties signed a supplementary agreement on changed cost of repair and modernization for aircraft carrier INS Vikramaditya (stands for "Almighty"). According to Indian sources, purchase of the Russian carrier would cost about $2.33 bln. Supposedly, lifetime of INS Vikramaditya would be 30 years.

Project 11434 aircraft-carrying cruiser Admiral Flota Sovetskogo Soyuza Gorshkov (formerly named Baku) joined Soviet Northern Fleet in 1987. After repair and retrofitting under Project 11430, the carrier's full displacement will be 45,000 tons; overall length will be 283.5 meters; overall beam will be 59.8 meters (become 8.8 meters wider). The ship will carry 30 aircraft on board including fighters MiG-29K and helicopters Ka-28 and Ka-31. Crew strength will exceed 2,000 men.

Err is that the amount of smoke to be generated while in operation or is it only preliminary.

Maybe that was the fire from the boiler.

 

[pmaitra]

Now it's on fire!

Ok, so there was indeed a fire. I have restored your post.

Maybe that was the fire from the boiler.

A high probability considering that most of the equipment including engines are new as stated in IDRW link posted in #1230
