This International Standard addresses the need to connect booms
17、having dissimilar connectors during oil spill incidents where various operators may join forces to combat an oil spill or where normally incompatible boom stock must be used together.The American Society for Testing and Materials (ASTM) Committee F-20 (Hazardous Substances and Oil Spill Response) ha
18、s been preparing standards on related subjects for years. This organization has prepared two standards relating to boom connectors, namely ASTM F962-99 and ASTM F1657-96.The first of these standards, ASTM F962, specifies standard mating requirements, or geometry, for boom connectors or adaptors. AST
19、M F962 was never widely accepted in the international community because many users believe that this mating geometry has inherent design limitations. In particular, the required strict tolerance between mating faces of the two joining connectors can result in connection problems. Some reported conce
20、rns or deficiencies with boom connector designs that use the ASTM F962 mating specifications are as follows: Slight bending along the length of the connector can easily occur during operation or, in particular, during roll-up or storage on the boom reel, resulting in the inability to join them toget
21、her again; The design is more susceptible to experiencing difficulties joining connector ends if the connector face has been dented or marred through impact; Dirt and debris can be trapped on a mating surface, preventing proper fitting and connection, or requiring careful cleaning of the connectors;
22、 During cold weather operations, ice can form at the mating faces, making connection difficult or impossible; and The connection is not always secure. The use of a self-locking pin has occasionally resulted in excessive play in the connection and eventual release.With respect to permanently incorpor
23、ating a universal requirement or standard connector in all boom systems (instead of using an adaptor only when required), discussions with spill response operators and oil boom producers clearly indicate that, in many cases, this will not provide an appropriate or realistic standard practice. Booms
24、and connectors are often designed or selected by an operator based on the needs that are suitable for their particular operating conditions. Also, producers choose connectors based on the needs of the particular boom design. In effect, many users think it is unlikely that any single standard connect
25、or mating criteria (as, for example, ASTM F962) will provide the characteristics to satisfy the specific requirements of all users.The second of these standards, ASTM F1657, was subsequently developed to provide another approach to oil boom connectors. Instead of providing a standard connector desig
26、n, it provides a common method for joining existing booms with different connector designs in the field during a major spill incident. This standard does not attempt to have all manufacturers and spill responders use universal connectors at all times. Instead, it specifies modifications on existing
27、connectors in the way of incorporating holes at specified locations to allow for this standard connection method during major response incidents. Alternatively, boom manufacturers may provide an adaptor that would accomplish the same end result.After considering these existing ASTM standards and dis
28、cussions with individuals involved in the development of these standards, i.e. spill responders and boom producers, this International Standard was developed to use the same mating specifications as in ASTM F1657. However, this International Standard encourages the use of separate adaptors in most c
29、ases, to avoid the possible adverse effects of modifications to existing connector designs when incorporating these mating specifications. These mating specifications may be incorporated into existing connectors, if preferred and possible, only when the manufacturer or user can ensure that the modif
30、ications will not alter the strength and performance of the connector.

31、 ISO 16446:2013INTERNATIONAL STANDARD ISO 16446:2013(E)Ships and marine technology Marine environment protection Adapter for joining dissimilar boom connectors1 ScopeThis International Standard specifies a universal method for the joining of oil spill containment booms with dissimilar connectors thr
32、ough the use of a standard adaptor with prescribed mating specifications. This International Standard does not intend to replace the design of existing connectors.This International Standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibi
33、lity of the user of this International Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.2 Terms and definitionsFor the purposes of this International Standard, the following terms and definitions apply.2.1boomfloatin
34、g barrier used to control the movement of substances that float2.2bridledevice attached to a boom to distribute the load exerted by towing or anchoring the boom2.3draftminimum vertical depth of the boom below the waterline2.4end connectordevice attached to the boom used for joining boom sections to
35、one another or to other accessory devices2.5freeboardminimum vertical height of the boom above the waterline2.6tensile strengthforce required to stretch boom components to the point where a failure occurs3 General functional conditionsThe main precondition for the successful use of an adapter for di
36、ssimilar boom connectors is that the design of any boom connector meets the following criteria: The boom connector shall be strong enough to withstand impressing forces relating to the type, size and purpose of the boom it is mounted on. Oil leakage shall be avoided between boom sections. The boom c
37、onnector shall be secure, as well as, easily connected and disconnected in and out of the water, in the presence of oil, dirt and ice, in rough water, or any combination thereof. Connectors that can be joined by simply drawing the ends together are preferred over those that require one to slide into
38、 the other. ISO 2013 All rights reserved 1BS ISO 16446:2013ISO 16446:2013(E) The boom connector shall be such that it matches the applicable boom end (see Figure 1) without male and female differentiation, and resists distortion, e.g. when winding on a reel. The boom connector shall be locked or sec
39、ured by wing nuts or self-locking pins which are preferably secured to the boom or end connector, are easy to handle (e.g. when wearing gloves) and, do not require the use of tools. Where tools are needed, they shall be commonly available tools. The boom connector shall not have any negative influen
40、ce on the booms performance, i.e. freeboard and stability, and transfer tensile forces between boom sections, if the boom design requires this.NOTE On some booms, the use of the adapter may cause a reduction in freeboard near the connector. This potential loss of freeboard is, however, outweighed by
41、 the benefit of being able to connect the dissimilar booms under emergency circumstances. Health and safety issues associated with the use of the boom shall be considered and mitigated.4 Design criteria4.1 Mating requirementsIn order to comply with the practice for the joining of booms with incompat
42、ible connectors, an appropriate number of adapters must be provided by the manufacturer or user that, on one side, connect to the existing connector and, on the other side, consist of a flat plate that incorporates the mating requirements as described in 4.2. This requirement encourages the use of s
43、eparate adapters to avoid the possible adverse effects of modifications made to existing connector designs when incorporating these mating specifications. However, in certain cases, the following mating requirements may be incorporated directly into an existing connector design, and thus preclude th
44、e use of a separate adapter. The latter option is possible only if the connector can accept the holes spaced as required without interfering with existing bolt holes or other connector features and if the manufacturer or user can ensure that the modifications will not alter the strength or performan
45、ce of the adapter.4.2 Bolt holesThe adapter shall have, on one side, a flat plate with a standard mating face with a minimum of three 16 mm holes, as shown in Figure 1, to accommodate 12 mm (or 1/2 inch) diameter AISI 316 stainless steel1)bolts. These bolts should be provided with the adapter. An ex
46、ample of the shape of the boom connector, as well as, the detail of the bolt connection is shown in Figure 1 and Figure 2, respectively. Using the boom design waterline as a reference point, the centre of the first hole shall be 120 mm above the waterline, the centre of the second hole shall be 240
47、mm below the centre of the first hole, and the centre of the third hole shall be 300 mm below the centre of the first hole. For larger adapters, additional holes shall be placed at 300 mm increments from the first hole. To avoid tolerance accumulations, the distance to each hole is measured from the
48、 centre of the first hole. To ensure proper mating with other adapters based on this International Standard, the mating surface shall not exceed 25 mm from the hole centres to the outer edge and shall have a minimum of 26 mm space in from the hole centres. This mating area shall be flat and clear of
49、 any interference.1) AISI 316 stainless steel is an example of a suitable product available commercially.
