Standard Specification for Warping Heads, Rope Handling (Gypsy Head, Capstan Head)

Standard Specification for Warping Heads, Rope Handling (Gypsy Head, Capstan Head)

ABSTRACT
This specification covers warping heads used with windlass, winch, and capstan drive units to pull rope on board ships. Warping heads are primarily for use with fiber rope, natural, or synthetic. Warping heads with external ribs or whelps on the barrel, notched flanges, attached storage drums, unfinished drums, or non heat-treated fabrications, are considered special. The size of the warping head shall be identified by the nominal barrel diameter measured at the smallest point of the barrel. These warping heads are furnished in two types: Type I is with a cylindrical barrel which is generally used in but not restricted to horizontal shaft applications and Type II is with a conical barrel which is mounted with the large end of the barrel toward the drive machinery. It is generally used in but not restricted to vertical shaft applications. On the other hand, the warping heads are divided into four grades according to composition: Grade 1 is fabricated from any combination of structural steel plate, pipe, tubing, or steel castings and joined by electric welding; Grade 2 is made from mild to medium strength steel; Grade 3 is fabricated from any combination of steel plate or steel castings and joined by electric welding; and Grade 4 is cast from high strength steel castings. Principal dimensions, tolerances, and strength requirements are discussed.
SCOPE
1.1 This specification covers warping heads used with windlass, winch, and capstan drive units to pull rope on board ships. Warping heads are primarily for use with fiber rope, natural, or synthetic.
1.2 Warping heads with external ribs or whelps on the barrel, notched flanges, attached storage drums, unfinished drums, or non heat-treated fabrications, are considered special and are permitted within the scope of this specification when fully described under special ordering information.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.

Standard Guide for Selection of Booms in Accordance With Water Body Classifications

SIGNIFICANCE AND USE
4.1 This guide is to be used to assist in the selection of containment boom in accordance with water body classifications.  
4.2 A small number of key parameters that generally affect boom performance have been used in Table 1, in order to enable the user to readily identify general criteria for boom selection.  
4.3 Many factors, other than those listed in Table 1, may be important in selecting containment boom for a particular application. Such factors include: flotation element length, wave length, the effect of stronger than minimum required strength members, shock loads, abrasion resistance, stability in roll, resistance to bridging, interval between anchor points and hand holds, use of reflectors or lighting, compatibility with fresh or salt water, and resistance to sunlight exposure.  
4.4 The values given in Table 1 are the recommended minimums for general purpose booms. As identified in 2.3, operational considerations may require trade-offs in boom properties. Special purpose booms, and general purpose booms used in special circumstances, may perform effectively with boom property values above or below those recommended in Table 1.  
4.5 Effective operation of oil spill control equipment depends on many factors, of which the prevailing environmental conditions are just a few. Factors such as, but not limited to, deployment techniques, level of training, personnel performance, and mechanical reliability can also affect equipment performance.
SCOPE
1.1 This guide covers the selection of containment boom that may be used to control spills of oil and other substances that float on a body of water.  
1.2 This guide does not address the compatibility of spill control equipment with spill products. It is the user's responsibility to ensure than any equipment selected is compatible with anticipated products.  
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Acoustic Emission Testing of Insulated and Non-Insulated Digger Derricks

SIGNIFICANCE AND USE
5.1 This test method permits testing of the major components of a digger derrick generated by the rapid release of energy from localized sources within the digger derrick under controlled loading. The energy releases occur during intentional application of a predetermined load. These energy releases can be monitored and interpreted by qualified individuals. Acceptance/rejection criteria are beyond the scope of this test method. The test may be discontinued at any time to investigate a particular area of concern, or to prevent a fault from continuing to ultimate failure of the digger derrick resulting from the application of the test load.  
5.2 This test method provides a means of detecting acoustic emission sources that may be defects, irregularities, or both, affecting the structural integrity or intended use of the aerial personnel device.  
5.3 Significant sources of acoustic emission found with this test method shall be evaluated by either more refined acoustic emission test techniques or by other nondestructive methods (visual, liquid penetrant, radiography, ultrasonic, magnetic particle, etc.). Other nondestructive methods may be required in order to precisely locate defects in the digger derrick, and to estimate their size. Additional tests are outside the scope of this test method.  
5.4 Defective areas found in digger derricks by this test method should be repaired and retested as appropriate. Repair procedure recommendations are outside the scope of this test method. Repair procedure recommendations are outside the scope of this test method.
SCOPE
1.1 This test method covers a procedure for acoustic emission (AE) testing of digger derricks.  
1.1.1 Equipment Covered—This test method applies to special multipurpose vehicle-mounted machines, commonly known as digger derricks. These machines are primarily designed to dig holes, set poles, and position materials and apparatus.  
1.1.1.1 Insulated and non-insulated type digger derricks may be evaluated with this test method.
1.1.1.2 Digger derricks, if so equipped to position personnel or equipment, or both, may also be evaluated with this test method in conjunction with Test Method F914.  
1.1.2 Equipment Not Covered—Excluded from this test method are general-purpose cranes designed only for lifting service and machines primarily designed only for digging holes.  
1.2 The AE test method is used to detect and area-locate emission sources. Verification of emission sources may require the use of other nondestructive test (NDT) methods, such as radiography, ultrasonic, magnetic particle, liquid penetrant, and visual inspection.  
1.3 Warning—This test method requires that external loads be applied to the superstructure of the vehicle under test. During the test, caution must be taken to safeguard personnel and equipment against unexpected failure or instability of the vehicle or components.

SIGNIFICANCE AND USE
3.1 This guide is meant to aid response teams who may use it during spill response planning and spill events.  
3.2 This guide should be adapted to site specific circumstance.
SCOPE
1.1 This guide covers the use of oil spill dispersants to assist in the control of oil spills. The guide is written with the goal of minimizing the environmental impacts of oil spills; this goal is the basis on which the recommendations are made. Aesthetic and socioeconomic factors are not considered, although these and other factors are often important in spill response.  
1.2 Spill responders have available several means to control or clean up spilled oil. Chemical dispersants should be given equal consideration with other spill countermeasures.  
1.3 This is a general guide only. Oil, as used in this guide, includes crude oils and refined petroleum products. Differences between individual dispersants or between different oil products are not considered. The dispersibility of the oil with the chosen dispersant should be evaluated.  
1.4 The guide is organized by habitat type, for example, small ponds and lakes, rivers and streams, and land. It considers the use of dispersants primarily to protect habitats from impact (or to minimize impacts).  
1.5 This guide applies only to freshwater and other inland environments. It does not consider the direct application of dispersants to subsurface waters.  
1.6 In making dispersant use decisions, appropriate government authorities should be consulted as required by law.  
1.7 This guide does not address getting regulatory approval.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 This standard does not purport to address all of the safety concerns, if any, associated with its use.
