SMM '82 (continued from page 20) analysis with emphasis on the lay barge, while H. Musch and J. Langer of Mannesmann Anla- genbau AG will describe use of the technique in great water depths. A refined analysis of environ- mental conditions for the design of marine pipelines will be the subject of a paper presented by scientists from the Danish Hy- draulic Institute in Horsholm. H. Schonfeldt and G. Schwiers of Blohm & Voss will examine production requirements of off- shore structures with an empha- sis on welding. H. Kuhn from the Menck Di- Write 439 on Reader Service Card vision of Koehring GmbH will re- port on underwater stabbing with a hydraulic hammer. Scientists from DFVLR (Co- logne) will examine research in diving medicine using the new diving simulator Titan, while col- leagues from Profoline Unter- wassertechnik and Ocean Consult GmbH will describe the use of Medusa, an unmanned remote controlled underwater vehicle, for track survey and pipeline in- spection. The development, construction and handling of a remote con- trolled soil investigation vehicle will be treated in a paper by German experts. J. Grunberg of IMS GmbH, Hamburg, will report on progress in the development of a computer program for the hydrodynamic analysis of fixed compact offshore structures. Developments in German off- shore oil and gas production will be discussed by three German scientists. Ice Technology Experts from the United States, Canada and Germany will present technical papers on such subjects as the test results de- termining mechanical properties of ice; methods of evaluating strength and elasticity of ice covers; analytical investigation of ice forces on cylindrical struc- tures; and analytical predictions of ship resistance in ice. Two papers will be presented on the topic of the ice breaker Max Waldeck. A report on tests of air-water jets to reduce resistance of ice going vessels will be presented as well as a discussion of icebreak- ing hopper suction dredges. The use of partly frozen arti- ficial sand islands as foundations for exploration platforms in Arc- tic Seas will be examined, as well as the effect of sea ice conditions on the accessibility of research stations on the Weddell Sea. A report on first-year pressure ridges in the Beaufort Sea by D. McGonigal and B.D. Wright of Gulf Canada Resources will con- clude the session on ice tech- nology. Oil Pollution Abatement Fourteen papers will be pre- sented during the session on oil pollution abatement. Specialists from B.P. International, Ltd., \ '4 . 4v . .. X In what may be maritime history, Bay-Houston Towing Company recently christened the four newest members of the fleet all on the same Jay. Left to right: The Captain W.D. Haden, the W.D. Haden. II. the Barbara H. ISeuhaus and the Mark K. A FAMILY AFFAIR. The biggest harbor towing company on the Texas Gulf Coast is no faceless corporation. It's Bay-Houston lowing. And it's owned and oper- ated by the Hadens, a family that has been involved in the towing business for over 100 years. That's why their fleet of diesel tugs, all the way up to the 4,200-horsepower Captain W. D. Haden, bears family names. Doing the job better than anyone else can is more than a challenge. It's a family tradition.
