1968: M/V Hohannes Frans was taking on water.  This 634-foot Dutch tanker with a cargo of oil reported that it was disabled in 10 to 15 foot seas taking on water 250 miles northeast of Bermuda.  CGC Dallas which was In the immediate area, received the same report from the subject via flashing light and immediately went to her assistance.  The pump provided by Dallas, however, failed to work properly.  A Coast Guard aircraft provided four additional pumps by the evening of Sept 19; Dallas reported that the flooding had been stabilized.  Three civilian tugs were enroute, with the first due on the 21st.  Weather conditions improved enough on the 21st for the master and crew to remain aboard and continue pumping.  The tug Foundation Vigilant arrived on scene on the morning of the 21st and took the vessel in tow.  The tug Tasman Zee arrived shortly thereafter and provided three pumps.  The three ships proceeded to Bermuda.  CGC Dallas proceeded to Ocean Station Echo.
