V HEld 87 Levingston Launches Jackup Drilling Rig For Dixilyn-Field Levingston Shipbuilding Com- pany has launched the Dixilyn- Field 87 (shown above) at its shipyard in Orange, Texas. The triangular shaped, Levingston de- signed Class 111-C jackup drill- ing rig is 200 feet by 186 feet by 23 feet. When this self-elevating drill- ing platform is completed, it will have three four-chord, square truss legs that will be 414 feet tall. These sturdy legs will allow the vessel to drill in 300 feet of water to a drilling depth of 25,- 000 feet. One of the customer requirements of this rig is that it be capable of operating in tem- peratures of minus 20 degrees centigrade, and withstand winds of up to 125 mph and seas of 50 feet. Accommodations are available for 80 people and the rig is equipped with two galleys and two messrooms. It will meet the requirements of the United States Coast Guard and the American Bureau of Shipping. Dixilyn-Field is a major oper- ator of land rigs as well as off- shore vessels, and has been in business 25 years. This world- wide company, based in Houston, is a subsidiary of Panhandle East- ern Pipe Line Company with head- quarters also in Houston.

Hampton Roads SNAME Hears Paper On Shipboard Piping The Hampton Roads Section held its most recent dinner/tech- nical meeting at Fisherman's Wharf in Hampton, Va. The eve- ning's paper titled "A Survey of Shipboard Piping Design and Fab- rication" was presented by Lamar E. Williams and Bob S. Oglesby. A large turnout of 139 members and guests was present to hear this informative paper. Mr. Wil- liams is presently employed as a senior engineer in the Hull Tech- nical Department of Newport News Shipbuilding. Mr. Oglesby is employed as supervisor of out- fitting in the Industrial Engi- neering Department of Newport News Shipbuilding. Their paper discussed the do- mestic and foreign practices rel- ative to shipboard piping design, fabrication, and installation. Al- though the paper's emphasis was on commercial shipbuilding, many practices discussed applied to both commercial and Naval work. Indi- vidually defined phases of piping design, fabrication, and installa- tion were discussed, as well as various "integrated" approaches to each of these activities. Mate- rial presented was based largely upon on-site surveys by the au- thors of 22 domestic facilities, in- cluding 13 shipyards, four design agents, two piping fabrication equipment manufacturers, two piping fabricators, and one re- search facility. Material from on- site surveys by the authors of four Western European shipyards was also presented. Following the presentation of the paper it was commented on by Harry Sheridan of David W. Taylor Naval Ship R and D Cen- ter, L.D. Chirillo of Todd-Seattle, Per Bech of Odense Steel Ship- yard Ltd., George Uberti of NAS- SCO, and George Ponton of Ad- vance Marine Design. All were in agreement that the paper is a valuable addition to the store of knowledge about the shipbuilding environment, and will prove to be a useful tool for increasing the productivity of the shipbuilding community.
