(a) Before you install or modify a production safety system, you must submit a production safety system application to the District Manager. The District Manager must approve your production safety system application before you commence production through or otherwise use the new or modified system. The application must include the design documentation prescribed as follows:
| You must submit: | Details and/or additional requirements: |
|---|---|
| (1) Safety analysis flow diagram (API RP 14C, Annex B) and Safety Analysis Function Evaluation (SAFE) chart (API RP 14C, section 6.3.3) (incorporated by reference in §250.198) | Your safety analysis flow diagram must show the following: (i) Well shut-in tubing pressure; (ii) Pressure relieving device set points; (iii) Size, capacity, and design working pressures of separators, flare scrubbers, heat exchangers, treaters, storage tanks, compressors, and metering devices; |
| (iv) Size, capacity, design working pressures, and maximum discharge pressure of hydrocarbon-handling pumps; | |
| (v) Size, capacity, and design working pressures of hydrocarbon-handling vessels, and chemical injection systems handling a material having a flash point below 100 degrees Fahrenheit for a Class I flammable liquid as described in API RP 500 and API RP 505 (both incorporated by reference in §250.198); and | |
| (vi) Piping sizes and maximum allowable working pressures as determined in accordance with API RP 14E (incorporated by reference in §250.198), including the locations of piping specification breaks. | |
| (2) Electrical one-line diagram; | Showing elements including generators, circuit breakers, transformers, bus bars, conductors, automatic transfer switches, uninterruptable power supply (UPS) and associated battery banks, dynamic (motor) loads, and static loads (e.g., electrostatic treater grid, lighting panels). You must also include a functional legend. |
| (3) Area classification diagram; | A plan for each platform deck and outlining all classified areas. You must classify areas according to API RP 500 or API RP 505 (both incorporated by reference in §250.198). The plan must contain: (i) All major production equipment, wells, and other significant hydrocarbon and class 1 flammable sources, and a description of the type of decking, ceiling, walls (e.g., grating or solid), and firewalls; and (ii) The location of generators and any buildings (e.g., control rooms and motor control center (MCC) buildings) or major structures on the platform. |
| (4) A piping and instrumentation diagram, for new facilities; | A detailed flow diagram which shows the piping and vessels in the process flow, together with the instrumentation and control devices. |
| (5) The service fee listed in §250.125; | The fee you must pay will be determined by the number of components involved in the review and approval process. |
(b) You must develop and maintain the following design documents and make them available to BSEE upon request:
| Diagram: | Details and/or additional requirements: |
|---|---|
| (1) Additional electrical system information; | (i) Cable tray/conduit routing plan that identifies the primary wiring method (e.g., type cable, cable schedule, conduit, wire); and |
| (ii) Panel board/junction box location plan, if this information is not shown on the area classification diagram required in paragraph (a)(3) of this section. | |
| (2) Schematics of the fire and gas-detection systems; | Showing a functional block diagram of the detection system, including the electrical power supply and also including the type, location, and number of detection sensors; the type and kind of alarms, including emergency equipment to be activated; and the method used for detection. |
| (3) Revised piping and instrumentation diagram for existing facilities; | A detailed flow diagram which shows the piping and vessels in the process flow, together with the instrumentation and control devices. |
(c) In the production safety system application, you must also certify the following:
(1) That all electrical systems were designed according to API RP 14F or API RP 14FZ, as applicable (incorporated by reference in §250.198);
(2) That the design documents for the mechanical and electrical systems that you are required to submit under paragraph (a) of this section are sealed by a licensed professional engineer. For modified systems, only the modifications are required to be sealed by a licensed professional engineer(s). The professional engineer must be licensed in a State or Territory of the United States and have sufficient expertise and experience to perform the duties; and
(3) That a hazards analysis was performed in accordance with §250.1911 and API RP 14J (incorporated by reference in §250.198), and that you have a hazards analysis program in place to assess potential hazards during the operation of the facility.
(d) Within 90 days after placing new or modified production safety systems in service, you must submit to the District Manager the as-built diagrams for the new or modified production safety systems outlined in paragraphs (a)(1), (2), and (3) of this section. You must certify in an accompanying letter that the as-built design documents have been reviewed for compliance with applicable regulations and accurately represent the new or modified system as installed. The drawings must be clearly marked “as-built.”
(e) You must maintain approved and supporting design documents required under paragraphs (a) and (b) of this section at your offshore field office nearest the OCS facility or at other locations conveniently available to the District Manager. These documents must be made available to BSEE upon request and must be retained for the life of the facility. All approved designs are subject to field verifications.
