The exact cause of the accident is not known. On 4 July, Mitsui O.S.K. Lines appointed Lloyd's Register to support investigations into the cause of the incident. As a precaution, the sister ships of "MOL Comfort" were withdrawn from the same route and their hull structures will be upgraded to increase the longitudinal strength. In addition, operational changes will be carried out to reduce the stresses on the vessels' hulls.
