14、reword These Rules contain the technical requirements and criteria employed by ABS in the review and survey of hydrocarbon production facilities that are being considered for Classification and for maintenance of Classification. It is applicable to Hydrocarbon Production and Processing Systems and a
15、ssociated utility and safety systems located on fixed (bottom-founded) offshore structures of various types. It also applies to systems installed on floating installations such as ships shape based FPSOs, tension leg platforms, spars, semisubmersibles, etc. There are differences in the practices ado
16、pted by the designers of fixed and floating installations. Some of these differences are due to physical limitations inherent in the construction of facilities on new or converted floating installations. Recognizing these differences, the requirements for facilities on fixed and floating installatio
17、ns are specified in separate chapters. Chapter 3 covers requirements for facilities on floating installations and Chapter 4 covers requirements for facilities on fixed installations. Facilities designed, constructed, and installed in accordance with the requirements of these Rules on an ABS classed
18、fixed or floating offshore structure, under ABS review and survey, will be classed and identified in the Record by an appropriate classification notation as defined herein. These Rules have been written for world-wide application and as such, compliance with individual requirements may require compr
19、ehensive data, analyses and plans to be submitted to demonstrate the adequacy of the facility. ABS acknowledges that there is a wide range of documents that may be required for submittal to satisfy these Rules. It is not the intention of these Rules to impose requirements or practices in addition to
20、 those that have previously proven satisfactory in similar situations. Design and installation requirements presented in these Rules are based on existing methodologies and attendant safety factors that are deemed to provide an adequate level of safety. Primarily, the use of such methods and limits
21、in these Rules reflects what is considered to be the current state of practice in the design and installation of offshore facilities. The application of these Rules by ABS will not seek to inhibit the use of any technological approach that can be shown to produce an acceptable level of safety. These
22、 Rules are applicable to the classification of facilities for which applications, or contracts for classification, are received on or after 1 January 2016. Changes to Conditions of Classification (1 January 2008) For the 2008 edition, Chapter 1, “Scope and Conditions of Classification” was consolida
23、ted into a generic booklet, entitled Rules for Conditions of Classification Offshore Units and Structures (Part 1) for all units, installations, vessels or systems in offshore service. The purpose of this consolidation was to emphasize the common applicability of the classification requirements in “
24、Chapter 1” to ABS-classed offshore units, pipelines, risers, and other offshore structures, and thereby make “Conditions of Classification” more readily a common Rule of the various ABS Rules and Guides, as appropriate. Thus, Chapter 1 of these Rules specifies only the unique requirements applicable
25、 to facilities on offshore installations. These supplemental requirements are always to be used with the aforementioned Rules for Conditions of Classification Offshore Units and Structures (Part 1). iv ABSRULES FOR BUILDING AND CLASSING FACILITIES ON OFFSHORE INSTALLATIONS .2016 Table of Contents RU

Petroleum is a mixture of many different hydrocarbons. Hydrocarbon Fire Test (2015) A test in which specimens of th
30、e relevant bulkheads or decks are exposed, in a test furnace, to temperatures corresponding to the hydrocarbon fire time-temperature curve as defined in API-RP-2FB or equivalent. Hazardous Area See “Classified Area”. High Integrity Pressure Protection System (HIPPS) An efficient option to replace a
31、mechanical safety device; an example is a pressure safety valve, with instruments, valves and logic. Ignition Temperature The minimum temperature required, at normal atmospheric pressure, to initiate the combustion of an ignitable mixture. Inert Gas A gaseous mixture, such as flue gas, containing in
32、sufficient oxygen to support the combustion of hydrocarbons. Interim Class Certificate A temporary representation to classification. The Interim Class Certificate is generally issued by the Surveyor attending commissioning of the facility and verification of compliance with these Rules. Issuance of
33、an Interim Class Certificate is subject to the terms and conditions found therein. Joiner Arrangement Construction details showing the combination of all structural fire protection materials. For example, a detail showing the connection of the ceilings to decks, ceilings to bulkheads, bulkheads to b
34、ulkheads, bulkhead construction details, deck construction details, etc. Jumper Ducts Openings in bulkheads (usually in the top half) used for air balance or return air. Lower Explosive Limit (L.E.L.) The lowest concentration of combustible vapors or gases, by volume in mixture with air, which can b
35、e ignited at ambient conditions. 14 ABSRULES FOR BUILDING AND CLASSING FACILITIES ON OFFSHORE INSTALLATIONS .2016 Chapter 2 Definitions, References, Acronyms and Abbreviations Section 1 Definitions 2-1 Machinery Spaces of Category A are spaces, and trunks to such spaces, which contain: i) Internal c
36、ombustion engine(s) used for main propulsion; or ii) Internal combustion engine(s) used for other purposes where such machinery has, in the aggregate, a total power, or combined rating of 375 kW (500 hp) or more; or iii) Any oil-fired boiler or oil fuel unit Manned Facility A facility with permanent
37、 occupied living accommodations or one that requires continuous presence of personnel for more than 12 hours in successive 24-hour periods. Marine Support Systems For floating installations, those functions required for maintaining the normal operations of a vessel (or MODU), such as power generatio
38、n, propulsion, navigation, HVAC, water treating, etc. These functions are neither directly nor indirectly related to the hydrocarbon production and process systems. Non-ducted Return Means of re-circulating conditioned air back to the air handler without the use of a dedicated duct. Open Drains Grav
39、ity drains from sources which are at or near atmospheric pressure, such as open deck drains, drip pan drains, and rain gutters. Operating Conditions A set of conditions (i.e., flowrates, compositions, temperatures and pressures) chosen for normal operation of a production facility at a particular po
40、int in the life of an oil or gas field. Other Machinery Spaces (versus Machinery Spaces of Category A) All spaces, other than machinery spaces of Category A, containing machinery, boilers and other fired processes, oil fuel units, steam and internal combustion engines, generators and major electrica
41、l machinery, oil filling stations, refrigerating, stabilizing, ventilation and air-conditioning machinery and similar spaces; and trunks to such spaces. Pad Gas Gas added to the vapor space of a vessel or tank to prevent an explosive or ignitable vapor-air mixture from forming. Process Areas Areas w
42、here processing equipment is located. This includes wellhead/manifold areas. Process Design Conditions A set of conditions used to design process components and systems. Process Support Systems Utility and auxiliary systems that complement the hydrocarbon production and process systems. A typical li
43、st of such systems is included in Chapter 3, Section 4 and Chapter 4, Section 4. These systems do not directly handle hydrocarbons. Produced Fluids Fluids coming out of completed wells, which may consist of oil, water, gas, and condensable vapor. Production Facilities For the purpose of these Rules,
44、 Production Facilities are typically the processing, safety and control systems, utility and auxiliary equipment, for producing hydrocarbon liquid and gas mixtures from completed wells or other sources. These facilities are generally inclusive from the inlet flange of the well fluid flowline above t
45、he water level to the point at which the departing pipeline enters the water. The facilities also include the safe disposal and/or collection of produced oil, gases and water. For a floating installation with the storage and offloading capability to shuttle tanker, the production facility is termina
46、ted at the inlet flange discharge into the storage tank. The storage tank and offloading piping/electrical systems arrangement are considered marine systems. Sanitary and Similar Spaces Communal sanitary facilities such as showers, baths, lavatories, etc., and isolated pantries containing no cooking
47、 appliances. Sanitary facilities which serve a space and with access only from that space are to be considered a portion of the space where they are located. Service Spaces (Low Risk) Lockers, storerooms, and working spaces in which flammable materials are not stored, such as drying rooms and laundr
48、ies. Service Spaces (High Risk) Lockers, storerooms, and working spaces in which flammable materials are stored, such as galleys, pantries containing cooking appliances, paint rooms and workshops other than those forming part of the machinery space.
