Concerned Sailors Warn of Unlit Drydock Sections Floating Around Bermuda

Floating drydock section

A group of Bermuda government officials and concerned yachting professionals are warning about recent sightings of at least two large sections of an unlit dry dock reportedly floating off Bermuda.

The sections are believed to belong to a drydock formerly belonging to the former Avondale Shipyard.

The drydock left the Mississippi River yard in September under tow to the Canary Islands, but people tracking the voyage says that evidence suggests that tow failed, perhaps during Hurricane Irma. Only about half of the drydock arrived in the Canary Islands under tow by the tug De Zhou, which remains at anchor in the Canary Islands. 

The group is now unofficially tracking sightings of the sections so it can warn ships and mariners of the hazard to navigation.

The group recording three separate sightings in May, the most on recent occurring 26 May 2018.
