CHAPTER 01 GENERAL

    CHAPTER 1 GENERALS

    1.1 Purpose

    In order to avoid or reduce damages as specified below for the platform during its construction, installation, commissioning, start-up and production, maintenance, conversion and final abandonment:

personnel injury

environmental pollution

facilities damage and property loss

    The “Safety Rules for Offshore Fixed Platforms” (hereafter referred as the Rulesis formulated in pursuance of “The

    Provisions on the Survey of Offshore Oil and Gas Production Facilities” (hereafter referred as the Survey Provisions) and “the Safety Control Provisions on offshore Petroleum Operations” (hereafter referred as the Safety

    Control Provisions).

    1.2 Scope of Application

    1.2.1 The Rulesare applicable to offshore fixed platforms (called the Platforms hereafter) (including the normal jacket, minimum structure and unmanned platform) installed and used in the internal sea, territorial sea, continental shelf and other sea areas under the jurisdiction of the Marine Resources Management of the People’s Republic of China.

    1.2.2 In the periods of design, construction, installation, inspection, commissioning and production of the platform, all the operators, designers, contractors for platform construction and installations, the certifying survey agencies for surveying offshore oil/gas production facilities (hereafter referred as Certifying Survey Agencies) and the third Survey Agencies shall comply with the requirements in the <Rules> and other laws and regulations of the People’s Republic of China.

    1.2.3 The design, construction, installation, commissioning and

    1-1

    production operations of the topside production facilities on the other types of fixed platforms such as tension leg platforms, guy-tower platforms, concrete gravitational platforms shall follow the relevant provisions of theRules.

    1.2.4 Safety rules for “Floating Production Storage Unit (FPSU)” will be issued separately. The safety requirements for the topside facilities of the FPSU, FPS and other mobile production platforms, however, can refer to theRulesuntil

    the special rules are issued.

    1.2.5 The provisions concerning platform abandonment and removal will be promulgated separately.

    1.2.6 Technical conditions for the production platforms which went into production prior to the promulgation of theRules

    shall meet the requirements in the originally applied rules or standards. But its refitting, modification and inspection during platform operation shall be complied with the relative requirements in theRules. If any items of the above

    related work can not meet theRulesfor reasonable

    causes , the platform operator must submit beforhand an application specifying such items to the China Offshore Petroleum Operation Safety Office (called the safety office hereafter). Conducting the work can be started only after the approval.

    1.2.7 The “Rules” are the primary regulations for platform safety. The relevant provisions of the applied specifications and standards shall be also followed to those not yet specified in theRules .

    The operator may adopt some safety measures different from some items specified in theRules, based on the

    special situation of the platform, guided by the advanced theory on system safety, using methods and the latest techniques for offshore facility safety, as well as following the latest version of safety provisions on offshore facilities and specifications for safety analysis. In this case, a scientific & systematic safety analysis is required first, to ensure with facts and data the reliabilities of the measures adopted and the risks and risk value of the adopted measures within the minimum, reasonable & practical

    1-2

    requirements, at the same time, the operator shall submit a formal written application to the safety office along with the safety analysis documents. The adopted measures can only be put into practice after being approved by the Office.

    1.3 Basic Principle

    1.3.1 Principles for hazard identification and risk prevention. In the periods of planning, designing, procuring, construction and production of the platform, the operators must adhere to the principles for hazard identification and risk prevention.

    (1) Keep close watch at the potential hazard causing big

    accidents, i.e. the five different potential hazard

    sources of explosion, fire, scorching hot, smoke and

    toxic gas (or heavy smoke) and a risk evaluation must

    be made.

    (2) Enough attention shall be paid on the hazard that may

    cause big accidents, and the necessary risk

    evaluation shall be made.

    (3) Other hazards which may not cause big accidents shall

    not be neglected and necessary risk evaluation shall

    also be made.

    1.3.2 Countermeasures for accidents

    Operators shall make up the countermeasures for accidents that may occur in the construction and production periods, including management countermeasures and hard ware facilities, such as safety management system, safety plan, emergency plan, emergency shutdown , fire protection, life-saving appliances and so on. The countermeasures shall be started at the beginning of preparation for normal operation, especially those of safety management, safety education/training and safety supervision.

    In order to avoid any big accidents and reduce damages or loss of the accidents,more attention is nededed when taking any countermeasures for the following cases:

    1-3

    (1) Detection, alarming, restriction (isolation, shutdown),

    fire protection for the fire, explosion, heat, smoke,

    flammable gas and toxic gas; and personnel

    protection, life-saving and survival when the above

    accidence occurs.

    (2) To avoid hydrocarbon leaking, blasting and serious

    accidents in this result such as fire, explosion,

    environmental pollution, blowout etc. in the operation

    of drilling/completion/work-over, production operation

    and concurrent operations .

    (3) To prevent the main structures on the platform from

    any damages under harmful and unexpected loads,

    especially the serious damages causing the

    structures failing to support the upside facilities, thus

    resulting in big accidents as hydrocarbon leaking and

    environmental pollution.

    (4) To avoid failures and serious damages of the

    machinery, piping and electrical system or facilities

    such as high temperature and high pressure

    equipment and electrical equipment, resulting in even

    more serious accidents and causing hydrocarbon

    leaking, pollution, fire, explosion, personnel

    injury/death etc.

    1.3.3 Safety Analysis

    Safety analysis is the effective method for hazard identification,risk prevention and setting up the correct countermeasures for accidents. The core of safety analysis is to identify hazard and analyse its possibility and results, to set up safety countermeasures based on both technology and economics. The designer, construction and installation contractors, operator and Certifying Survey Agencies and the third survey agencies of the platform shall all comply with the principles of safety analysis and take necessary safety analysis.

    1.4 The Safety Office Reserve the Right of Interpretation and the Right of Revision to the “Rules”.

    1-4

    1.5 Definition of Terminology used in the “Rules”.

“Certifying Survey Agencies” means the certifying survey

    agencies for surveying offshore oil (gas) production facilities approved by Safety Office.

    “ The Third Survey Agencies” are the survey agencies employed by and on behalf of platform operators to conduct the reviewing,checking and inspection.

    “Applied Specifications and Standards” means the technical specifications and standards complying with the requirements of Article 12 of the “Survey Provisions for Offshore Oil and Gas Production Facilities”, and being applied by the platform operator during design, construction, installation and production operations of the platform and applied by the certifying survey agencies during executing the certifying inspections.

    “Minimum platform” means a production platform without self-contained workover rig with limited wells, and less topside facilities . Its substructures is characterized by any one of the following following features:

    1) Well conductor (s) are served as structural and/or axial

    foundation elements;

    2) All or most of the joint connections of substructural

    elements are attached to piles/pile sleeves directly by

    means of non-welded mechanical methods as such

    connected with bolt, pin, clamp, etc;

3) Other types of simple substructure

    “unmanned platforms” means the platform with no

    accomodation quaters. In normal production condition,

    no body works and operates on the platform. In the

    special conditions, such as in the period of maintaining,

    dealing with the emergency breakdown, approved

    visiting and investigation , checking and regular

    checking, but he number of the people allowed to land

    up the platform shall be as less as possible and they

    1-5

are not allowed to stay over night on board.
