ABSTRACT The U.S. Coast Guard's success with the high seas skimming barrier prompted the development of a smaller, half-scale version for use in protected bays and harbors. The smaller version (SCOOP) enables more rapid deployment with significantly fewer people. Individual components of the system include a 65-foot section of skimming barrier with redesigned skimming struts, 200 feet of containment boom, two 30-foot work boats for storage, transport, and operation of the system, trailers to carry the boats to the scene, and an oil recovery system including double-acting diaphragm pump, gravity-type oil-water separator, and 750-gallon collapsible storage bags. In tests at the Environmental Protection Agency's Oil and Hazardous Materials Simulated Environmental Test Tank (OHMSETT) facility, the SCOOP exhibited recovery efficiencies between 30 percent and 60 percent over a speed range of 0.5 to 1.75 knots. The oil recovery rate was between 30 and 70 gallons per minute over the same speed range. At speeds below 0.9 knots there were no losses of oil from the boom. The system has been delivered to the Coast Guard Gulf Strike Team in Bay St. Louis, Mississippi, where it is being evaluated through use in routine spill response operations and exercises.

ABSTRACT This paper describes the development of an oil recovery system to be used in conjunction with the U.S. Coast Guard's high seas oil containment barriers. The system was tested at the EPA's OHMSETT facility in 1975. Its oil recovery capability was shown to be good, with promise for yet better recovery when used on a large spill. Operational practicality was demonstrated in sea trials during May 1976, when the barrier was string towed, catenary towed, and moored in a tidal current. Because of the difficulty of handling large or complicated equipment in offshore conditions, a major design criterion was that the system be as simple as possible. Weir skimmers are particularly simple, but collection of more oil than water or air requires that the weirs follow the vertical motion of the waves. Simplicity and efficiency were achieved by utilizing the wave-following ability of the Coast Guard barrier design. Weirs were built into six struts at the center of a length of barrier, so that barrier deployment results in simultaneous skimmer deployment. To recover oil, it is only necessary to attach pump hoses to the barrier. Three double-acting diaphragm pumps are used. These self-priming pumps were specifically designed to pass any debris that can enter through the three-inch diameter suction hoses. Hydraulic drive was chosen so the pumps could be powered by the Coast Guard's ADAPTS diesel-engine-driven hydraulic power units.

Flight Testing the ADS-33E Cargo Helicopter Handling Qualities Requirements Using a CH-53G

Flight tests with a German Army Sikorsky CH-53G helicopter were performed to evaluate the applicability and repeatability of the U.S. Army's Aeronautical Design Standard (ADS)-33E-PRF cargo helicopter handling qualities requirements. The objectives were to corroborate earlier findings and to propose modifications if deemed necessary. The CH-53G was chosen because it is the largest helicopter operated by the German Army, and its dedicated role is cargo and troop transport. The quantitative criteria and the associated boundaries as specified in the standard were largely confirmed. Several flight test maneuvers were revised and tailored. Generally, the heights for performing the near-earth maneuvers were increased. The time/tolerances experienced were borderline desired/adequate or adequate.

Described in this chapter is an innovative online course that was created to support Spanish language students whose study abroad program was cancelled during the summer of 2020 due to the pandemic. While many students were able to enroll quickly in summer online language course offerings at their home campus to substitute for their study abroad coursework, students who were scheduled to complete field experiences in Spain as part of their certificate in Spanish for Professionals were unable to do so. In response to this problem, the author created an online professional practicum course to substitute for students' service-learning course in Spain. The design, development, and delivery of the online course, which featured a virtual language exchange between students in the U.S. and Spain, is the focus of the present chapter. Also described in this chapter is the conceptual framework that underpins sound instructional design for online communicative language teaching.
