H o n g k o n g United Dock Ships 210-Ton Buoy For PEMEX

A 210-ton buoy was recently raised onboard the heavy-lift vessel John Henry in Hong Kong for shipment to Mexico. The buoy was ordered by IMODCO for PEMEX, the Mexican national oil company, and constructed by Hongkong United Dockyards Ltd. of Hong Kong.

The buoy had been previously lifted by the giant floating crane Proteus I from the Kowloon yard into the water, and was moored alongside the dockyard until it was loaded onto the John Henry.

The buoy consists of a circular hull bound by one rotating assembly. The hull measures 12.5 meters in diameter, 4.27 meters in height (41 feet by 14 feet), and is divided into six compartments, half of which are filled with polyurethane foam materials.

The vessel loading operation involved twin derricks, each capable of lifting 216 tons.

Once onboard, the buoy was lashed in position before the John Henry began its trans- Pacific voyage to Cortzacoalcos, near Veracruz in the Gulf of Mexico.
