In view of the vast working range, execrable natural conditions and a large number of large-sized purposed- built working vessels on the site for the waterway regulation works in the Changjiang Estuary, the major factors affecting the operational days of these large working vessels at the sea are analyzed and the engineering measures to improve the effective offshore operational days of working vessels are expounded. Statistics and analyses are made of the offshore operational days of the working vessels for the second phase of the waterway regulation works in the Changjiang Estuary to work out the workable days and effective operational days of two large-sized purpose-built working vessels.
