August 15 - Marcon International of Coupeville, USA, has been chosen to market four massive concrete caisson sections constructed in 1981 to drill exploration wells under the shallow Beaufort Sea in the Canadian Arctic.
Designed to be bottom founded, the hollow reinforced caisson sections are made from lightweight concrete, each about 69 m long x 15 m wide x 11.5 m high and weighing around 5,000 tonnes
According to Bob Beegle, president of Marcon International, the company has successfully brokered a number of supply vessels, barges and tugs out of the Canadian Arctic in the past years.
He noted that the caissons can be shipped via submersible barge or independently towed over short distances.
