This report, developed at the National Maritime Research Center at Galveston, Texas, reviews reasons for drydocking ships, basic types of drydocks in current use, and the process of drydocking a U. S. vessel in a commercial floating drydock in an American Shipyard. A normal underwater inspection procedure conducted for mandatory periodic survey by the United States Coast Guard and the American Bureau of Shipping, is described and comments made on problems encountered in preparation for inspection, recoating, and repairs made to satisfy the Coast Guard and National Bureau of Standards. In view of the ever-increasing size of modern ships and the consequent increased cost of drydocking these ships, this report identifies major problems associated with drydocking and proposes areas of study by Marad to eliminate or minimize these problems.
