Screening Protocol

ABSTRACT An enhanced propane underwater bubbler system designed to allow the testing of fire-resistant booms in flames was installed at Ohmsett in the fall of 1998 by the Minerals Management Service (MMS) and the US Navy Supervisor of Salvage and Diving (SUPSALV). The test is based on a screening protocol for testing fire resistant booms in waves and flames developed for MMS and the Canadian Coast Guard (CCG). The cornerstone of the test is an underwater bubbler system to create air-enhanced propane flames that produce an average total heat flux to the surface of a candidate containment system in the range of 110 to 130 kW/m2 and flame temperatures near the containment device on the order of 900°C. The candidate boom is stretched over the center of the bubbler, parallel to the long dimensions of the test tank, and tensioned to realistic towing forces. The fire exposure portion of the test involves three cycles of one hour of exposure to air-enhanced propane flames in waves, followed by a one-hour cool-down period in waves alone, and conforms to ASTM F 2152-01. Since the air-enhanced propane system was developed, 11 fire resistant boom systems have been tested. These include: three refractory fabric booms, one stainless steel boom, three water-cooled blanket prototypes, three reflective/insulating blanket prototypes, and one water-cooled boom. This paper summarizes the test methods used and the results.

Operating Characteristics

ABSTRACT Environment Canada's Emergencies Engineering Division is spearheading a program in conjunction with the Canadian General Standards Board that would see the development of a certification and listing program in addition to a national standard for the testing of sorbent materials. Funding for this program is provided by Environment Canada (EC), Canadian Coast Guard (CCG), Marine Spill Response Corporation (MSRC), U.S. Coast Guard (USCG), and U.S. Minerals Management Service (MMS). The test methods are based upon those defined by the American Society for Testing and Materials and previous test methods developed by Environment Canada for our series of reports entitled Selection Criteria and Laboratory Evaluation of Oil Spill Sorbents. This series, which was started in 1975, encompasses a number of commercially available oil spill sorbents tested with different petroleum products and hydrocarbon solvents. The testing program will categorize the sorbents according to their operating characteristics. The main categories are oil spills on water, oil spills on land, and industrial use. The characteristics we will be evaluating with the new test protocols include initial and maximum sorption capacities, water pickup, buoyancy, reuse potential, retention profile, disintegration (material integrity), and ease of application and retrieval. In the near future we plan to incorporate changes to the test that would involve increasing our list of test liquids to encompass spills in an industrial setting, in addition to testing sorbent booms and addressing the disposal problem.

Object and purpose of research. The article is an extensive analytical review devoted to modern management decisions at the level of the government and the three key US naval services – the Navy, Marine Corps and Coast Guard, collectively known as the Naval Service, as well as the main trends in the development of the US Navy. Materials and methods. The study was carried out on the basis of the latest strategic documents defining the short-term and long-term plans for the US naval shipbuilding, adopted in 2020–2021. Main results. The main directions of the US Navy public funding are described in detail, the prospects for the development of the US navy and the possibilities of its rearmament are analyzed, the main competitor countries of the United States claiming control over the World Ocean and the Arctic are identified. Conclusion. The study makes it possible to adequately assess the scale of the current US administration's military plans related to future shipbuilding programs, taking into account Russia's military and strategic interests.

Main Component

The Explosive Destruction System (EDS) was developed by Sandia National Laboratories for the US Army Product Manager for Non-Stockpile Chemical Materiel (PMNSCM) to destroy recovered, explosively configured, chemical munitions. PMNSCM currently has five EDS units that have processed over 1,400 items. The system uses linear and conical shaped charges to open munitions and attack the burster followed by chemical treatment of the agent. The main component of the EDS is a stainless steel, cylindrical vessel, which contains the explosion and the subsequent chemical treatment. Extensive modeling and testing have been used to design and qualify the vessel for different applications and conditions. The high explosive (HE) pressure histories and subsequent vessel response (strain histories) are modeled using the analysis codes CTH and LS-DYNA, respectively. Using the model results, a load rating for the EDS is determined based on design guidance provided in the ASME Code, Sect. VIII, Div. 3, Code Case No. 2564. One of the goals is to assess and understand the vessel’s capacity in containing a wide variety of detonation sequences at various load levels. Of particular interest are to know the total number of detonation events at the rated load that can be processed inside each vessel, and a maximum load (such as that arising from an upset condition) that can be contained without causing catastrophic failure of the vessel. This paper will discuss application of Code Case 2564 to the stainless steel EDS vessels, including a fatigue analysis using a J-R curve, vessel response to extreme upset loads, and the effects of strain hardening from successive events.
