SYDNEY/KUALA LUMPUR – Norwegian car carrier Hoegh St. Petersburg has reached the area in the southern Indian Ocean off Australia where two floating objects, suspected to be debris from the missing Malaysian jetliner, were spotted, the ship's owner said on Thursday.
The large objects, which Australian officials said were spotted by satellite four days ago in one of the remotest parts of the globe, are the most promising lead in days as searchers scour a vast area for the lost plane with 239 people on board.
The car carrier was on its way from Madagascar to Melbourne when it got a request from Australian authorities to assist in investigating the objects spotted by satellite four days ago in one of the remotest parts of the globe, around 2,500 km (1,500 miles) southwest of Perth.
"We've got a request from Australian authorities to search the area, and we will assist as long as needed," said Kristian Olsen, a spokesman at Hoegh Autoliners.
No confirmed wreckage from Malaysia Airlines flight MH370 has been found since it vanished from air traffic control screens off Malaysia's east coast early on March 8, less than an hour after taking off from Kuala Lumpur for Beijing.
Officials cautioned it could take several days to confirm if they were parts of the Malaysia Airlines Boeing 777, and Malaysia's government said the search would continue elsewhere despite the possible sighting in the southern Indian Ocean.
"There remains much work to be done to deploy the assets. This work will continue overnight."
Hishammuddin said the information on the objects received from Australia had been "corroborated to a certain extent" by other satellites, making it more credible than previous leads.
The larger of the objects measured up to 24 meters (79 ft), long and appeared to be floating in water several thousand meters deep, Australian officials said. The second object was about five meters (16 feet) long. Arrows on the images pointed to two indistinct objects apparently bobbing in the water.
"It's credible enough to divert the research to this area on the basis it provides a promising lead to what might be wreckage from the debris field," Royal Australian Air Force Air Commodore John McGarry told a news conference in Canberra.

Another official in Malaysia said investigators were "hopeful but cautious" about the Australian discovery.
The satellite images, provided by U.S. company DigitalGlobe, are stamped with a record date of March 16, meaning that the possible debris could by now have drifted far from the original site.
Australian officials said an aircraft had dropped a series of marker buoys in the area, which will provide information about currents to assist in calculating the latest location.
The captain of the first Australian air force AP-3C Orion plane to return from the search area described the weather conditions as "extremely bad" with rough seas and high winds, and said there was no sign of any objects.
"The weather conditions were such that we were unable to see for very much of the flight today but the other aircraft that are searching, they may have better conditions," Royal Australian Air Force Flight Lieutenant Chris Birrer told reporters.
At least one aircraft, a Royal New Zealand Air Force Orion, was still in the search area, while other aircraft including a U.S. Navy P-8 Poseidon were returning to Perth, according to the Australian Maritime Safety Authority (AMSA).
A Norwegian car carrier diverted from its journey from Madagascar to Melbourne to help with the search and had arrived in the area, the ship's owner said. A Royal Australian Navy ship equipped to recover any objects was also en route, but was still "some days away", Young said.
The fate of Flight MH370 has been baffling aviation experts for nearly two weeks.
Investigators believe that someone with detailed knowledge of both the Boeing 777-200ER and commercial aviation navigation switched off the plane's communications systems before diverting it thousands of miles off its scheduled course.
Exhaustive background checks of the passengers and crew aboard have not yielded anything that might explain why.
The huge potential breakthrough in an investigation that had appeared to be running out of leads was revealed by Australian Prime Minister Tony Abbott, who told parliament the objects had been located with satellite imagery.
He added that he had already spoken with his Malaysian counterpart, Najib Razak, and cautioned that the objects had yet to be identified.
"The task of locating these objects will be extremely difficult and it may turn out they are not related to the search for MH370," Abbott said.
The dimensions of the objects given are consistent with at least one of them possibly being the major part of a 777-200ER wing, which is around 27 meters (89 feet) long, though Australian officials cautioned the first images were indistinct.
The relatively large size of the objects would also suggest that, if they do come from the missing aircraft, it was intact when it went into the water.
University of Western Australia Professor of Oceanography Charitha Pattiaratchi said that, based on currents in the area, if the debris is from the plane it probably would have entered the water around 300-400 km (180-250 miles) to the west.
The search area covered an ocean ridge known as Naturalist Plateau, a large sea shelf about 3,500 meters (9,800 feet) deep, Pattiaratchi said. The plateau is about 250 km (150 miles) wide by 400 km (250 miles) long, and the area around it is close to 5,000 meters (16,400 feet) deep.
"Whichever way you go, it's deep," he said.
