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.

This chapter introduces the use of a learning objects content development tool, the eLearning Objects Navigator, (eLONTM) as a strategy for creating, classifying, and retrieving reusable learning objects and reusable information objects. The use of eLONTM provides a context for rapid deployment of these SCORM-conformant packages to mobile learning devices as well as to learning management systems for a beta test with the U.S. Coast Guard Institute. Presented in this chapter is the underlying theoretical framework for the development of eLONTM as well as the specific design decisions made regarding the deployment of PDA mobile learning devices to military personnel. Furthermore, initial results from the beta test yield positive results as well as a series of lessons learned.

ABSTRACT A flaring burner for disposal of oil recovered from spill cleanup operations has been built and tested, and is being incorporated into a prototype Flaring Burner Disposal System for the U.S. Coast Guard. This system will meet Coast Guard requirements for air transportability, rapid deployment, and safe operation in remote arctic or offshore locations. Tests demonstrated that the burner was capable of the following:Smokeless burning of light oil at a design rate of 180 gallons per minute (gpm), with water spray addition.Burning of 200-centistoke (cs) oils with acceptable smoke and low droplet fallout at rates up to 90 gpm.Burning of 1600-cs oil with smoke and droplet-fallout levels that may be acceptable under certain circumstances. This viscosity was in excess of the Coast Guard design objectives for viscosity level.Smokeless burning of low-viscosity water-in-oil emulsions.Nearly smokeless burning of light oils at reduced rates without water spray addition (a consideration for arctic usage).

ABSTRACT Rising waters on the Illinois River during April 1979 caused breaks in the levee near Meredosia, Illinois. The swollen river flooded 10,000 acres of farmland, as well as the asphalt storage tank farm of the Meredosia Oil Terminal. The 35 tanks within the terminal included several multimillion gallon tanks of hot asphalt, as well as those containing the diesel fuel for the heating system. The floodwater reached a depth of 12 feet and the hydrostatic pressure of the rising waters lifted the diesel fuel tanks and toppled them. Thousands of gallons of oil spilled from the vents at the top of the tanks, or from the broken pipelines at their bases. A westerly wind moved the oil out over the flooded farmland. The terminal operator's resources were depleted after long efforts to prevent the levee breaks. The spill-ctonainment dike around the tank farm was underwater, so several thousand feet of floating containment boom was brought in to surround the tank farm. A Marco Class self-propelled skimmer was flown in by the U.S. Coast Guard Strike Force. However, inspections on the second day revealed that much of the oil had diffused out over the floodwater and did not appear to be recoverable. Response forces concentrated on the spilled oil within the tank farm and the potential of teh toppled and floating tanks. After 3 days of cleanup, a brief, violent storm blew oily debris back to the terminal from across the lake. Now a massive debris recovery effort was begun in addition to the oil recovery. Cleanup efforts continued for 51 days, until by June 4, 1979, the floodwaters had dropped below the tank farm's spill-containment dike.

ABSTRACT This paper presents an overview of the 1979–1980 work performed at the OHMSETT spill research facility of the U.S. Environmental Protection Agency (EPA). The experiences of these 2 years are discussed in the light of the purpose and objectives of OHMSETT, as is the probable direction of research there during the coming years. Foremost among the objectives has been the evaluation and advancement of the state of the art for spill response. The bulk of the effort at OHMSETT, therefore, has been toward testing and investigating ways to improve equipment. This paper briefly summarizes the results of 12 equipment performance evaluations, 2 new equipment development programs, and an experimental oil weathering program. The equipment evaluated was the U.S. Coast Guard high speed “zero relative velocity” skimmer prototype; the Sapiens Sirene skimming system; the Hydrovac System sweeper arm; the Soviet harbor oil/debris skimmer; the Oil Mop remote skimmer prototype; the Versatile Bennett Arctic skimmer prototype; the Petro-Fiber, Oljesanering, AB Sorbent Distribution/Recovery System; the Global Oil Recovery (DiPerna) skimmer; the Clean Atlantic Associates Fast Response Open Sea Skimming System; the University of Lowell oil gelation system; the Peabody Meyers Corp. Vactor air conveyor; and a Coleman Environmental Pollution Control Equipment Co. vacuum truck. The equipment developed was the Johnson sampler for stratified liquids and the Johnson high speed skimmer. Several new areas of work are anticipated for the near future. These include evaluation of cleanup equipment in the presence of ice, increased emphasis on testing at spills-of-opportunity, a study of some of the problems associated with high viscosity water-in-oil emulsions, testing separators and pumps for spill response, increased emphasis on smaller skimmers, and further testing with hazardous materials.

ABSTRACT A concept to control and recover oil slicks in potential water current velocities of 10 knots is presented. The energy dissipation concept involves gradually slowing down the fast-moving oil slick and a layer of water flowing directly beneath such that the critical velocity Vc is never reached at the oil-water interface. In the process of slowing down, the oil layer thickens to a point where conventional recovery techniques may be used to remove the oil. Three research programs are discussed that investigate applications of the energy dissipation concept. These efforts under sponsorship of the U.S. Coast Guard include Hydronautics’ Surface Velocity Retarder Oil Skimmer (SVROS), Seaward's Streaming Fiber Device, and Texas & University's Porous Barrier System. Results of preliminary testing are discussed and analyzed. Program plans for subsequent work on the energy dissipation concept are described.

ABSTRACT Derelict vessels pose significant hazards to the communities in which they reside due to the cornucopia of oils and hazardous materials they contain including fuel oils, lubricating oils, lead-based paints, acid batteries, asbestos, and refrigerants like ammonia and Freon. Additional threats include attractions for children and vagrants, navigational hazards, and potential locations for illegally dumped oil or hazardous materials. The removal of derelict vessels is a complex undertaking due to restrictive legal authorities, ownership questions, high costs, and limited funding streams. The overview provided covers important points to consider prior to initiation of any removal action for a derelict vessel. Points include owner identification and notification, federal removal authorities, removal funding, and potential disposal methods. Included are vessel removal success stories and best practices from a U.S. Coast Guard - State of Washington partnership and the program titled ‘Operation Trash Compactor’. This partnership successfully mitigated pollution threats from the vessels FAL-91 and HERON. Ultimately the creation of such partnerships or creations of taxation systems or mandatory environmental insurance programs are important tools to ensure proper disposal of derelict vessels. According to African legend older elephants instinctively would direct themselves when they reached their time to an area to die called the elephant graveyard. The myth was due partly to the fact that while elephants are the largest of land mammals, their bones were supposedly never found lying around openly on the African plains. Contributing to the myth was that older elephants and elephant skeletons were often found in the same habitat. Thus the elephant graveyard was believed to be the final destination for literally thousands of elephants and that their bones and tusks would litter the graveyard. While elephants may have been believed to have had elephant graveyards to go to die in, the question remains for today'S maritime vessels; where do vessels go to die? Like elephants, today'S fleets of maritime vessels are relatively large as far as man-made structures, and older vessels may be found clumped together near industrial waterways or low rent marinas. Unlike elephant bones, however, the steel frames and structures of vessels do not quickly decompose and remain visible symbols of our nation'S limited success in creating a process for dealing with vessels that are no longer profitable to operate. Derelict is broadly defined as deserted, neglected, or abandoned property. Many states have statutes which include specific legal definitions of derelict and/or abandoned. Derelict vessel is the term best used to describe vessels that are no longer profitable to operate and may have exceeded their service life. In most cases these vessels will incur more costs for proper maintenance than profits gained from their operation. Thus, these vessels represent a negative operational value. In addition most such vessels posses an overall net negative value as any inherent recycling value is more than offset by incurred disposal costs. Without a positive operational or overall value, such vessels are ripe for becoming a derelict/abandoned vessel and thus be a burden for their community, local, state, and federal government. Derelict vessels are public eye-sores and pose hazards to the communities in which they reside due to the cornucopia of hazardous materials they contain. Hazardous materials include fuel oil, lubricating oils, lead-based paints, acid batteries, asbestos, and refrigerants like ammonia and Freon. Other threats include physical threats from attracting children and vagrants, local environmental impacts from the leaching of iron, potential homes for illegally dumped oil or hazardous materials, and navigational hazards. While many derelict vessels are abandoned, not all are. Abandonment refers to a vessel which has no active owner, although the definition can vary from state to state. The Abandoned Barge Act (48 USC 4701) defines an abandoned barge as “an owner who has moored, stranded, or left a barge unattended for longer than 45 days” (Abandoned Barge Act, 48 USC 4701). Frequently for derelict vessels an owner or operator can be found, however they often lack the financial means to correct the vessel'S deficiencies. Independent surveys from 1991 by the U.S. Coast Guard and the U.S. Army Corps of Engineers found approximately 1300 and 4000 abandoned vessels respectively (USCG Marine Safety Manual, Volume 10, Chapter 10). In response to this national survey, U.S. Congress enacted the Abandoned Barge Act (ABA) of 1992. Unfortunately, as the name implies, the act is relevant only to barges, specifically those over 100 Gross Tons. Other federal laws against derelict/abandonment of a vessel are also narrowly constructed (Boring, 2006). The limitations of other federal laws are addressed later in this paper as they apply to the various challenges presented by derelict vessels. For communities seeking to properly dispose of derelict vessels, there are several core issues to consider. These include ownership, removal authority, funding sources, environmental cleanup, and disposal methods. While this paper is intended to provide a general discussion of primary issues involved in the derelict vessel removal process, it is by no means all-inclusive.

Abstract The marine salvage industry plays a vital role in protecting the marine environment. Governments, industry and the public, worldwide, now place environmental protection as the driving objective, second only to the safety of life, during a marine casualty response operation. Recognizing over 20 years after the passage of the Oil Pollution Act of 1990 that the effectiveness of mechanical on-water oil recovery remains at only about 10 to 25 percent while the international salvage industry annually prevents over a million tons of pollutants from reaching the world's oceans, ten years ago the United States began implementing a series of comprehensive salvage and marine firefighting regulations in an effort to improve the nation's environmental protection regime. These regulations specify desired response timeframes for emergency salvage services, contractual requirements, and criteria for evaluating the adequacy of a salvage and marine firefighting service provider. In addition to this effort to prevent surface oil spills, in 2016, the U.S. Coast Guard also recognized the salvage industries advancements in removing oil from sunken ships and recovering submerged pollutants, issuing Oil Spill Removal Organization (OSRO) classification standards for companies that have the capabilities to effectively respond to non-floating oils. Ten years after the implementation of the U.S. salvage and marine firefighting regulatory framework, this paper will review the implementation of the U.S. salvage and marine firefighting regulations and non-floating oil detection and recovery requirements; analyze the impacts and effectiveness of these new policies; and present several case studies and recommendations to further enhance salvage and oil spill response effectiveness.

ABSTRACT A harbor oil spill removal-recovery system comprises four subsystems: containment, recovery, storage and transfer, and separation. Commercially available subsystems were analytically evaluated Based on the evaluation, six containment booms, ten skimmers, three pumps, two towable storage tanks, and three oil-water separators were tested in rivers, wave tanks, and on land. The highest test-rated subsystems were then assembled into two harbor oil spill removal-recovery systems: a confined-area system, and an open-area system. Both systems were then tested in a Naval harbor. The tests showed that essentially all the oil intentionally spilled in the harbor, with EPA approval, was recovered. Major findings were (1) none of the booms tested could contain oil when towed at 2 knots, (2) for 1-mm thick oil slicks, the maximum oil pickup rate was 55 gpm, obtained with a large advancing weir skimmer, (3) the towable tank concept was effective, and (4) neither a gravity nor coalescer oil-water separator operating alone could produce a water effluent with less than 10 ppm of oil; however, a gravity and a coalescer separator operating in series produced a water effluent of less than 10 ppm of oil

ABSTRACT Spills seriously strain the normal abilities of organizations to gather, process, and distribute information. Added to the problems of supporting local multiagency decisions within the Unified Command (UC), there often are pressures from groups not directly involved in response operations and the public for rapid access to information about the spill. A UC can provide Command Post staff, official personnel not on-scene, and the public with specifically tailored information by establishing Incident Internet Operations. Incident-specific Internet sites can disseminate information about the response rapidly to the general public and specify target audiences inside and outside the Command Post. The Hazardous Materials Response Division, Office of Response and Restoration, National Oceanic and Atmospheric Administration worked with the U.S. Coast Guard to successfully deploy an Incident Internet Operations site during the M/V New Carissa incident. Examples of Incident Internet Operations from the New Carissa incident and other spills are available for viewing on-line at http://www.incidentnews.gov.
