Test Drive

The new A-frame and grapple equipment for the WHOI long core system are tested on a mock-up of the stren section of the research vessel Knorr in June 2006 at the Allied Equipment Company in Sherwood, Oregon. Engineers Joel Dille and Kevin Workman put the new equipment through its paces. The robust hydraulic gear was specially developed to launch and recover WHOI’s new 150’ long coring system, which weighs more than 30,000 pounds.
