Woods Hole Explores the Deep with Unique Rope

The Woods Hole Oceanographic Institution (WHOI), the largest independent institution of its kind in the world, recently began developing a new piston corer for retrieving sediments from the ocean floor. Once complete in 2006, the deep-water coring system will be the largest in the U.S. and among the biggest in the world. The corer’s enormous weight — 25,000 pounds — coupled with the environmental demands associated with working in water up to 20,000 ft. deep presented major technical challenges to the system required to lower the corer to the sea floor then recover it, along with its ancient sediment samples.

Located in Cape Cod, Mass., the Woods Hole Oceanographic Institution is a private, independent, not-for-profit corporation dedicated to research and higher education at the frontiers of ocean science. Its primary mission is to develop and effectively communicate a fundamental understanding of the processes and characteristics governing how the oceans function and how they interact with the Earth as a whole.

The institute’s new piston corer will be able to penetrate up to 160 ft. into the ocean floor, giving scientists a view of hundreds of thousands or even millions of years of climate and ocean history.

In the past, research vessels like those used by WHOI and other ships engaged in activities ranging from drilling to deep-water salvage typically used steel ropes to lift heavy objects. The new mission required new technology, particularly in the rope used and its ability to deploy and recover the massive corer while providing long and satisfactory life. To support the 25,000-pound coring system and withstand the environmental demands presented by deep-water exploration, WHOI selected a custom braided, synthetic fiber rope from Puget Sound Rope, a unit of the Cortland Companies. The rope will be based on Puget Sound Rope’s Plasma 12 x 12-strand, which uses Spectra polyethylene fiber from Honeywell Specialty Materials, as well as other products and technologies, to gain its incredible strength and other attributes. Spectra fiber, pound for pound, is 10 times stronger than steel. Once completed, WHOI’s rope will be nearly 23,000 ft. (7,000 m) long and, while just two inches in diameter, will be able to lift more than 350,000 pounds. The corer will be installed on the 279-ft. research vessel Knorr, which is owned by the U.S. Navy and operated by WHOI.

The Knorr and its 2,700 sq. ft. of floating laboratory space are scheduled to begin work with the new piston corer in 2006.

VideoRays Used in Unique Under Ice Search

VideoRay was recently involved in an unprecedented search using multiple VideoRay micro-ROVs in extreme conditions. The three-day search took place from January 9-11 on the frozen St. Lois River in Duluth, Minn. Jim King the owner of Spirit Lake Marina off the St. Louis River fell out of his rear-tiller motorboat while marking the location of buoys on October 25, 2004. Since the accident there has been an ongoing search with no successful results largely because of large area and lack of witnesses who could identify a ‘point last seen’.

Since the accident the St. Louis County Sheriffs office has logged more than 3,000 hours of search time. The latest effort to recover Mr. King’s body came in January when the St. Louis County Sheriffs office organized a massive and unique search. The search occurred on the St. Louis River which was frozen over more than 15 inches.

Eight VideoRay micro-ROVs were used for the search. The Sheriffs office developed a search grid covering a square half mile area. Six identical micro-ROVs were operated simultaneously from portable ice houses on the frozen river, each equipped with a Desert Star Pilot positioning system to track the ROVs and transmit the data wirelessly to the command center about a half mile from the tracking station.

“As far as we know, this is the first time in the world anyone has had this many ROVs (Remotely Operated Vehicles) together to search for a body,” said Tom Crossmon of the St. Louis County Rescue Squad. Crossmon also said the worldwide ROV community is small; when they e-mailed members looking for advice, no one said they had encountered such a large recovery operation.

“The result of the search was better than expected – we were able to search a large section of the river. We did not find the body – but we know far better where it is not located. We also learned that sonar was a critical tool in this kind of search due to the severely restricted visibility of the water. We recommend that VideoRay owners use the new “performance tether” when operating in this kind of high current environment, since it has much less drag, and with multiple holes and shallow water we did not need to use very long sections of tether. Finally, the positioning system was key to making sure that the areas searched were the areas we expected” stated McCauley.

RV Dyson Outfitted with Simrad

Simrad, Inc. of Lynnwood, Wash., recently outfitted RV Dyson with a full complement of state-of-the-art fish location and monitoring equipment.

C&C Technologies Performs COE Survey at Key West

C & C Technologies is performing pre-dredge and post-dredge, quality assurance (QA) hydrographic surveys for the Jacksonville District of the Corps of Engineers, as a sub-consultant to Johnson–McAdams Survey & Mapping, LLC. The objective of the survey is to provide geo-referenced multibeam data, which is used to determine the progress of Bean-Stuyvesant’s 12.8-cu.-yd. yard BH Dredge, MARICAVOR, working on the Key West Harbor, Florida, dredging project.

The deliverables include color-coded plots of the acceptance areas. The charts are color coded to indicate channel bottom materials that are above project grade, below project grade, above allowable over-depth grade, and areas below over-depth grade. Volume computations are determined for each of these categories of channel bottom. The survey is being performed using C&C’s R/V Inland Surveyor equipped with an EM 3002 multibeam echosounder, navigation computers, C-Nav RTK GPS and Hypack volume computation software. “To date, the project has been extremely successful,” said Frank Lipari, C&C ‘s Government Contracts Manager. “We expect to continue to support the project’s quality assurance needs over the next year, until completion of the dredging operations.”
