9、ganizations with a common interest in offshore cargo handling equipment, to provide a code of practice, within the context of statutory requirements. It is largely based on provisions set out in the OFFCON Code of Practice issued in 1986 and adopts the plating system for containers introduced by OFF
10、CON. It is the principal objective of this code to give recommendations for the safe and efficient operation of containers used in trans-shipments between shore bases and offshore installations, and between offshore installations. It is intended that owners and users of such containers should observ
11、e all the recommendations of the code except in those circumstances where this would hinder rather than assist the attainment of safe and efficient operation. Because of the variety of containers to which this code may be applied, it is not possible to lay down detailed constructional recommendation
12、s, but appendix A dealing with design and manufacture has been included to provide guidance on the factors to be considered by designers and manufacturers to ensure that containers are fit for purpose. It is recognized that the guidance cannot strictly apply to the design and manufacture of containe
13、rs already in existence, however, owners should assess existing equipment in the light of the guidance and either modify or re-rate their equipment as necessary. In particular, attention is drawn to. The Offshore Installations (Operational Safety, Health and Welfare) Regulations, 1976 (SI 1976 No. 1
14、019) which apply to containers used offshore. Those parts of these Regulations relating to testing, thorough examination, certification and marking of lifting appliances and lifting gear are particularly relevant. In addition, the requirements of the Freight Containers (Safety Convention) Regulation
15、s, 1984 (SI 1984 No. 1890) apply to those containers which meet the definition of “freight container” in those Regulations. Those containers will require approval and plating in accordance with the Regulations, in addition to the recommendations of this code. These containers are often referred to a
16、s ISO containers and are either tested in accordance with BS 3951-21) or the equivalent test methods of the Freight Container (Safety Convention) Regulations, 1984. These tests require a vertical top-lift test but do not include a top-lift test by slings with an included angle of 90, which is the re
17、commendation of this code (see 6.3). Therefore containers which meet the test requirements of BS 3951-2 or the Regulations are unlikely to meet the recommendations of this code unless they are modified or re-rated. This code represents a standard of good practice and takes the form of recommendation
18、s. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document compris

21、9 BSI 12-19981 1 Scope This code gives recommendations for plating, marking, examination, testing and repair of containers intended for transit to and from offshore installations in the offshore oil and gas industry. The code is also applicable to containers which are retained offshore for a protrac
22、ted period but which require periodic movement during that time to, from or between offshore installations. This code is not applicable to items of plant and equipment covered by the Diving Operations at Work Regulations 1981 (SI 1981 No. 399). Guidance on design and manufacture of containers is giv
23、en in appendix A. NOTEThe titles of the publications referred to in this code are listed on the inside back cover. 2 Definitions For the purpose of this British Standard the following definitions apply. 2.1 container an item of equipment lifted by slings, whose primary purpose is the transportation
24、of goods, materials or equipment, which may be permanently installed in the container, to, from and between offshore installations 2.2 competent person a person having such practical and theoretical knowledge and actual experience of the containers, which have to be inspected or examined, as will en
25、able him to detect defects or weaknesses, which it is the purpose of the inspection or examination to discover, and to assess their importance to the safe use of the container NOTEThe competent person should seek such specialist advice and assistance as will be required to enable him to make necessa
26、ry judgements and be a sound judge of the extent to which he can accept the supporting opinions of other specialists (see also appendix B). 2.3 chequer plate a steel plate having regularly patterned raised portions, often used as flooring 2.4 hook load the total weight suspended from the crane hook
27、2.5 lifting set items of non-integral lifting equipment used to connect the container to the lifting appliance 2.6 maximum gross weight (MGW) the maximum permissible combined weight of the container and its contents NOTEThe term weight has been used throughout as being the terminology generally adop
28、ted and more commonly understood than the term mass. 2.7 non-destructive examination (NDE) any technique used to detect discontinuities in a material without subjecting it to physical stress 2.8 offshore installation any installation which is, or has been maintained, or is intended to be established
29、, for the carrying on of any activity to which the Oil and Gas (Enterprise) Act, 1982, applies NOTEThese activities are: a) the exploitation or exploration of mineral resources in or under the shore or bed of controlled waters; b) the storage of gas in or under the shore or bed of controlled waters
30、or the recovery of gas so stored; c) the conveyance of things by means of a pipe, or system of pipes, constructed or placed on, in or under the shore or bed of controlled waters; and d) the provision of accommodation for persons who work on or from an installation which is or has been maintained, or
31、 is intended to be established, for the carrying on of an activity falling within paragraph a), b) or c) above or this paragraph. 2.9 owner the legal owner of the container or his delegated nominee 2.10 proof load test the deliberate application of a predetermined overload to a container NOTEIn this
32、 standard a proof load test is used to test the container in accordance with 6.3. 2.11 safe working load/payload (SWL/payload) the maximum permissible weight of cargo which may safely be transported by the container 2.12 tare the weight of the container without cargo which includes all fixtures norm
33、ally fixed to the container in service, excluding the lifting sling and shackles 3 Design and construction Containers manufactured after the publication of this code should be manufactured in accordance with the recommendations given in appendix A.

35、zed or accidental removal. The plate should be fitted to a door, or, on containers with no doors, in a prominent position. NOTEAluminium rivets have been found to be unsuitable as a fixing method in the offshore environment and should not be used. 4.2 Information 4.2.1 The plate should be headed “DA
36、TA PLATE”. 4.2.2 The following headings and the related information should be permanently and legibly marked on the plate, in characters not less than 4 mm in height: a) owners name; b) container identification (unit number, see 4.3); c) tare weight (in tonnes); d) SWL/payload (in tonnes); e) maximu
37、m gross weight (in tonnes); f) date of last test/examination using the following: 1) suffix T for proof load test, non-destructive examination and visual examination; 2) suffix VN for non-destructive examination and visual examination; 3) suffix V for visual examination only. To avoid confusion, the
38、 plate should not carry the date of the next test/examination. 4.2.3 Provision should be made on the plate to facilitate etching, engraving or stamping to record a minimum of six examinations. 4.2.4 A recommended format for the plate is shown in Figure 1. 4.3 Container identification Each container
39、should be provided with a unit number issued by the owner as a unique identification which should be noted on all certification and logistical documentation. 4.4 Date of last test/visual examination 4.4.1 This should be the date on which the most recent test/visual examination was carried out to the
40、 satisfaction of a competent person. NOTESpecific details of these tests and examinations are contained in clause 6. 4.4.2 Examination dates should be as laid down in 6.2 and Table 1. 4.5 Supplementary information Users of this code may add any other information relevant to their particular applicat
41、ion, e.g. function, manufacturing data. However, to avoid confusion it is recommended that such supplementary information should be kept to a minimum. 4.6 Marking of the plate The competent person should etch, engrave or stamp the plate immediately after the test and/or examination is carried out, u
42、sing characters not less than 4 mm in height. NOTE 1The presence of a valid plate indicates to personnel handling a container, the existence of a certificate and its status (see 6.6). NOTE 2Containers with less than one month of currency of certification should not be shipped to any offshore install
43、ation, except by prior agreement with the shipper. 5 Marking 5.1 Safety markings 5.1.1 The tops of closed containers and the top rails of open and framed containers should be marked to clearly delineate their perimeter, particularly in poor light. NOTESuggested markings are as follows: a) a band of
44、solid contrasting colour not less than 100 mm wide round the roof perimeter of closed containers; b) contrast hatching on the top rails of open and framed containers. 5.1.2 All container roofs, including those constructed from chequer plate, should be coated with a permanent non-slip medium. 5.2 Ide
45、ntification markings 5.2.1 All containers should be identified by the unit number as required by 4.3. 5.2.2 The container identification should be prominently displayed on all sides of the container (as viewed from ground level) in characters of a contrasting colour, not less than 75 mm high. NOTEFo
46、r open sided containers it may be necessary to attach panels specifically to carry the container identification. 5.2.3 Where reasonably practicable, the container identification should be displayed on the roof, in characters not less than 300 mm high. The marking should be carried out in such a way
47、as to avoid incorrect interpretation (e.g. by underlining). Where applicable the lower edge of the marking should be positioned near the side of the container in which the door is located.
