Maintenance failures resulted in a "catastrophic" engine breakdown on a DFDS ropax that left a seafarer seriously injured.
The UK Marine Accident Investigation Branch (MAIB) found that damage to a connecting rod was not spotted early enough to prevent a fire on the 1,900-dwt Finlandia Seaways (built 2000) off Lowestoft in eastern England in 2018.
The incident took place on 16 April when the ship was 11 nautical miles (20 km) from the English coast en route from Zeebrugge in Belgium to Rosyth in Scotland.
