HATCHING AN OPEN SHIP REVOLUTION

New generations of shortsea and long-haul containerships seeking operational advantages through the elimination of hatch covers are being pioneered by several shipping lines. Proponents of the hatchcoverless concept contend that the strength required of hatch covers to cope with higher container deck loadings has reached the stage where hatch cover weights are often at the limit of the lifting capacity of shore-side cranes. The way in which drainage is handled is explained, and benefits of the design are discussed, including faster turnaround time. For one of the new designs, calculations reportedly suggest that the absence of hatch covers will allow a 20% increase in homogenously loaded containers as compared with a conventional containership. Profile drawings of a hatchcoverless ship are provided.
