The panel submitted its report to Shipping Secretary Mohammad Mezbah Uddin Chowdhury on Monday, according to the ministry’s spokesman Mohammed Jahangir Alam.
However, he did not shed light on any other details relating to the report.
After the tragedy on Dec 24, the ministry formed a seven-strong committee headed by Joint Secretary Tofael Islam to look into the incident.
The fire broke out at the vessel’s engine room and the panel blamed the owner, master and engine drivers, said a member of the probe panel, on condition of anonymity.
The report also highlighted the lack of a monitoring survey but did not directly blame the surveyor for the blaze, according to the official.
The installation of a faulty engine has been identified as the main reason behind the blaze, he added.
In the report, the panel also recommended introducing a ticketing system and scrapping of the rotation system, among others.
