KUALA LUMPUR: Malaysia is considering deploying underwater vehicles as authorities prepare for a long-term search effort for missing flight MH370, an official said late on Thursday. Deputy defense minister Abdul Rahim Bakri said national oil company Petronas would provide two autonomous underwater vehicles (AUVs) to help search for the Malaysia Airline Boeing 777-200, which disappeared without a trace. “Up to now Petronas has given full commitment, dedicating at least two AUVs to help the search,” he said in a press conference. As the so-far futile search continues, he said Petronas was also mulling providing underwater sonar equipment and remotely operated vehicles. Abdul Rahim said Malaysia’s oil and gas firm Sapura Kencana was offering a multibeam echo-sounder which was being considered by the government. Meanwhile, a resumption of the search was hindered Wednesday by technical troubles, with a mini-sub lasting only two hours in the water before it had to be raised.
