Ocean Infinity spent 151 days at sea; MH370 not found

Ocean Infinity completed a seabed search that produced no confirmed findings of Malaysia Airlines Flight MH370, Malaysian investigators told relatives on March 8, 2026. The company left the search area on January 23, 2026 after finishing the most recent phase.

The campaign operated in two windows, March 25–28, 2025 and December 31, 2025–January 23, 2026. Teams logged 28 days of active searching and covered about 7,571 square kilometres in the southern Indian Ocean. Malaysia engaged Ocean Infinity under a no-find, no-fee contract that would pay $70 million only if wreckage were located; the agreed search site measured 15,000 square kilometres and Ocean Infinity surveyed roughly half of that area.

Since joining the assignment in 2018, Ocean Infinity reports a cumulative 151 days at sea and more than 140,000 square kilometres of seafloor mapped. The company used autonomous underwater vehicles and seabed mapping systems to scan the ocean floor for wreckage and anomalies.

Ocean Infinity’s chief executive, Oliver Plunkett, said, “we haven’t been able to find it,” and added the work was carried out with “a level of precision and speed unimaginable in 2018.”

Flight MH370 disappeared from radar on March 8, 2014 while flying from Kuala Lumpur to Beijing with 239 people on board. Earlier searches, including a deep-sea towfish survey from October 2014 to June 2015, covered different parts of the Indian Ocean and did not locate the main wreckage.

Investigators revised search areas over the years using satellite data and drift modelling of debris. Ocean Infinity and Malaysian investigators plan to continue analysing data collected during the missions.

Malaysia’s Cabinet approved a 12-month extension for the hunt from July 1, 2026 through June 30, 2027, leaving open the possibility of further seabed operations under the existing contract terms.
