San Juan “Graving Dock"
Rare Infrastructure Alongside the Port of San Juan
☐
The San Juan graving dock served numerous vessels during the 1950s, 1960s, and 1970s that required repairs or scheduled maintenance. Among the vessels
serviced at the dock were U.S. Navy submarines, Greek merchant ships, oil tankers belonging to Esso and other oil companies, vessels of Alcoa Shipping, and
cruise ships of the Cunard and passenger lines. 39 Cruising tourism into and out of San Juan increased during the 1960s and 1970s, from 77,500 passengers in
1966 to 211,200 in 1972.40 Because of its size, however, the San Juan graving dock could not be used for the newer larger vessels. In 1978 the operation of the
graving dock passed from Sucesores de Abarca to Perez Y Cia. which operated it until June 1, 1999, when the government of Puerto Rico purchased the graving
dock from the federal government and the Puerto Rico Ports Authority assumed the operation of the graving dock.
A facility to accommodate this service is located on the southwest corner of the Isla Grande peninsula and situated to the east of San Juan Bay (Exhibit 2). The
graving dock is located on the waterfront at the end of an industrial area. In the vicinity of the graving dock are other piers for shipping lines, warehouses and
the abandoned facilities of an iron works foundry. The graving dock is situated along Piers 15 and 16. Shop buildings, storehouses, and other industrial
structures are situated adjacent (or in close proximity) to the graving dock. The structure is a 672.5 ft. x 91 ft. wide pressure relieved type, one section drydock
originally constructed between 1939 and 1941 (Exhibit 1). It is a concrete structure supported directly on soil. A railroad track utilized for portal crane purposes
surrounds the graving dock on the shoreward side. The facility includes an underslab hydrostatic pressure relief drainage system, perimeter culverts and one
pump house. A connecting tunnel runs from the pump house to the graving dock. These components create a system of flooding, draining and dewatering this
drydock. Other key components of the industrial operation of this facility include the removable steel caisson and the flooding sluice gate.
