Maersk Line has contained a fire on another boxship a week after the fatal blaze on Maersk Honam.
The Danish owner said the incident occurred in the container underdeck of the 6,188-teu Maersk Kensington (built 2007) on Thursday evening.
The ship, owned by US subsidiary Maersk Line Limited (MLL), was en route from Salalah, Oman, towards Suez.
"All 26 crew members are safe and accounted for and the fire is reported to be contained," the company said.
"Safety measures were taken immediately. The crew reacted swiftly and as per procedure, by release of CO2 into the cargo hold to contain the fire."
The cause is not yet known.
No cargo link
But an initial investigation has indicated there is no link between the cargo in the affected hold and the cargo that caught fire on the 15,262-teu Maersk Honam (built 2017) on 6 March.
Maersk Kensington is currently at anchor outside the port of Salalah, and is getting assistance from shore.
There are 3,518 boxes on board, corresponding to 5,616 teu.
Five crewman died following the devastating blaze on Maersk Honam off India.
Another 22 were rescued, but reportedly suffered exposure to toxic fumes.
