Three NKK Yards To Convert Marcona Ore Carrier Into World's Largest Slurry Ship The world's largest slurry ship, 141,400 dead- weight tons, will be built from the hull of the San Juan Exporter, a 106,229-dwt ore carrier, by Nippon Kokan, Japan's only integrated shipbuild- er-steelmaker. Announcing the historic conversion, Hiroo Ikematsu, manager of NKK's New York ship- building department, said the vessel will be jum- boized by increasing her length 132 feet 5-3/4 inches and her depth 8 feet 2-7/16 inches. The converted Exporter is scheduled for delivery in March 1972. NKK will also install equipment systems which will enable the ship to load and discharge slurry iron ore. The Exporter was the world's largest ore carrier when delivered to her owner in 1967, San Juan Carriers, Ltd., a division of Marcona Corp., San Francisco. Jumboizing will involve three NKK shipbuild- ing and repair facilities. The original hull will be deepened at Asano Dockyard near Tokyo. The new hull portion will be built at Tsurumi Shipyard also in the Tokyo-Yokohama district. Conversion will be completed at the company's mammoth, ultra-modern Tsu yard in central Japan. Slurry handling equipment will be installed at Asano. To be supplied by San Juan Carriers, equipment includes: seven pumps; two diesel en- gines for powering pumps which discharge slurry ore; 54 special Marconajet units which combine water with semi-solid slurry cargo for discharge by the pumping system; piping for slurry load and discharge, which features a remotely-con- trolled special valve system. The world's first carrier-to-slurry-ship conver- sion was completed in March 1970 by Nippon Kokan. The original vessel, the 48,968-dwt San Juan Merchant, built by NKK in 1967, was re- named Marconaflo Merchant. She is engaged in transporting slurry ore from the Marcona Mines in Peru to Japan and other countries, the same route to be assigned to the new San Juan Exporter. En jay Chemical Appoints O.C. & K.R.
