The Calamity Jane is a support vessel for Allseas' mechanical subsea pipeline vessel Digging Donald, which is fully remote controlled from the Calamity Jane and has a maximum depth of 350 meters. In addition to trenching, other support services on dynamic positioning can be performed by the Calamity Jane, such as pipeline crossing preparation, mattress installation in deep water, surveys and pigging and testing of pipelines, all diverless. The vessel is 151 meters long, 20 meters wide and can accomodate 72 persons. She is equipped with one fixed lifting frame for lifting up to a maximum of 200 tons and a general purpose crane for lifting up to 55 tons. The Calamity Jane is owned by the Swiss-based Allseas Group S.A. which is one of the major offshore pipelay and subsea construction companies in the world, operating specialised vessels - which were designed in-house.
The Calamity Jane has entered the Port of Rotterdam this evening and is currently berthed at Mammoet Schiedam.
