Maritime and Port Authority of Singapore (MPA) said Dali also underwent and passed two separate foreign port state inspections in June and September 2023 with the next classification and statutory surveys due in June 2024.
"In the June 2023 inspection, a faulty monitor gauge for fuel pressure was rectified before the vessel departed the port," it said in a statement, Wednesday.
Dali was flagged with Singapore from October 2016 and is classed by classification society ClassNK.
MPA said classification societies are generally authorised by a flag administration to monitor compliance to technical standards and the applicable regulations by vessels registered under its flag.
Meanwhile, MPA in an earlier statement said the ship management company, Synergy Marine Pte Ltd, reported to the agency that just before the incident, Dali had experienced momentary loss of propulsion.
"As a result, it was unable to maintain the desired heading and collided with the Francis Scott Key bridge.
"The vessel was reported to have dropped its anchors as part of the vessel's emergency procedures prior to its impact with the bridge. The vessel was under pilotage at the time of the incident," it said.
The agency also said investigators from the Transport Safety Investigation Bureau and MPA are travelling to Baltimore, Maryland to support the investigation.
Authorities announced that six people were presumed dead Tuesday evening and they have shifted from a search and rescue operation to a recovery effort, media reported.
All 22 crew members are safe and accounted for.
