MOL Comfort

On 17 June 2013, MOL Comfort suffered a crack amidships in bad weather about 200 nautical miles (370 km; 230 mi) off the coast of Yemen and eventually broke into two after hogging. The vessel was underway from Singapore to Jeddah, Saudi Arabia, with a cargo of 4,382 containers equivalent to 7,041 TEU. The crew of 26—11 Russians, one Ukrainian and 14 Filipinos—abandoned the ship and were rescued from two life rafts and a lifeboat by the German-flagged container ship Yantian Express, one of three vessels diverted to the site of incident by ICG Mumbai.[5][6][7] After the structural failure, both sections remained afloat with the majority of the cargo intact and began drifting in an east-northeast direction. Smit Salvage Singapore was contracted to tow the sections to safety.[8]

On 24 June, four oceangoing tugboats arrived at the scene and began towing the bow section to safety.[9] However, before any salvage operations of the stern section could commence, water ingress was reported on 26 June.[10] On the following day, the stern sank at 14°26′N 66°26′E to a depth of 4,000 metres (13,000 ft). Some of the approximately 1,700 containers on board were later confirmed floating near the site. While no major oil leak was reported, the stern section was said to contain about 1,500 tons of fuel.[11]

On 2 July, the tow of the bow section broke free in bad weather[12] but the towing line was reattached the next day.[8] On 6 July a fire broke out in the rear part of the bow section. Unable to get the blaze under control in bad weather the salvage vessels asked for help from an Indian Coast Guard patrol boat with external fire fighting equipment.[13] By 10 July most of the 2,400 containers on board had been destroyed by fire.[14] The damaged bow section sank the next night at 19°56′N 65°25′E to a depth of 3,000 metres (9,800 ft) with what remained of the cargo and 1,600 metric tons of fuel oil in the tanks. No spill apart from a thin oil film on the surface has been reported, but some containers were spotted floating around the sinking site.[15] The cause of the fire remains unknown.

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to support investigations into the cause of the incident.[16] As a precaution, the sister ships of MOL Comfort were withdrawn from the same route and their hull structures will be upgraded to increase the longitudinal strength.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.[17]

The sinking of MOL Comfort cost the insurers between 300 and 400 million dollars in claims. The hull and machinery of the vessel were insured for $66 million.[18] By December 2014, the insurers (Tokio Marine & Nichido Fire Insurance Co.) were among 100 companies, including Mitsui O.S.K. Lines Ltd., who had launched lawsuits against MHI, reportedly on the grounds that the accident and consequent loss of ship and cargo was caused by a design flaw in the freighter.[19]

As of 2021, the loss of all 4,293 containers on board is the largest number of containers lost in a single event.[20]
