EXECUTIVE SUMMARY This document defines paint color and pipe marking requirements for an FPSO operating offshore Brazil. The Brazilian Norma Regulamentadora 26 and 30 are the foundation of this document. This document applies to the Shipyard, Topsides Fabrication Yard, Equipment Suppliers, and others. The markings established by this document shall enable crew members to quickly identify possible hazards in the vicinity of certain systems.

2.0

BACKGROUND Petrobras and partners (henceforth the “Client”) are developing the "Carioca Wells" within the concession areas related to the Santos Basin, off the coast of Brazil. The Client invited the Schahin Group and MODEC International, Inc. (henceforth the “Company”) to tender FPSO specifications for a VLCC conversion scenario with a minimum storage capacity of 1,600,000 bbl of crude oil. The Client specified that the FPSO shall be spread-moored in a maximum water depth of 2,126 meters. The FPSO is intended to receive production from subsea oil wells and shall have production plant facilities to process the fluids from the subsea production, stabilize them, and separate produced water and natural gas. Processed liquids shall be metered, stored in the vessel cargo storage tanks, and offloaded to shuttle tankers. High CO2 concentrate produced gas shall be compressed, dehydrated, and used as a fuel gas. Surplus gas shall be injected into the reservoir. Low CO2 gas shall be imported for fuel gas and gas lift use as well as combined with the high CO2 produced gas for reservoir injection. Produced water shall be disposed of overboard after appropriate treatment. The Process Plant shall have the following capacity:

3.0

•

Production and treatment of 19,200 Sm3/day of liquids (at 15.6 ºC and 101.3 kPa (a)) and up to 16,000 Sm3/d of crude oil (at 15.6 ºC and 101.3 kPa (a)) and 16,000 m³/d of produced water.

•

Treatment and compression of 5,000,000 Sm3/d of associated gas.

•

Treated seawater injection capacity of 19,200 m3/d at 25,000 kPa (a).

BASIS International regulations under which the offshore facility is built and operated require that a uniform scheme be used to identify pipes and pipe systems containing hazardous fluids or pressures. Moreover, the adoption of and adherence to a recognized industry practice for the identification of potential hazards are important elements of the Company’s HSEQ strategy. The Company’s standard 0003 “Topsides Paint Color Scheme and Pipe Marking Specification,” 0381-MI20-00S1-0031, follows the ANSI / ASME A13.1 “Pipe Labeling Requirements,” which does not consider Brazilian National Regulations. Therefore, this document is for Brazilian offshore projects only, as it is specific to the locale.

4.0

GENERAL The Brazilian Regulatory Standards (NR-26 and NR-30) aim at establishing the colors that must be used at work sites to prevent accidents, identifying safety equipment, delimiting areas, identifying the channeling employed in the industries for the transportation of liquids and gases and warning against risks. Colors must be adopted for security purposes to indicate and warn about existing risks.

Color stripe width shall be a minimum of 40% of the outside diameter of the pipe, but shall not to be less than 3 inches (75 mm). For the pipe diameter less than 3 inches (75 mm), the width may be equal to the outside diameter. The color yellow can be combined with the color black to obtain a greater contrast. Black stripes (verticals or diagonals) and black squares will be used over yellow when a better visibility for the signaling is required.

6.2

LABELS The legend labels and color indicator bands should be provided at suitable locations along the length of each pipe branch line, so that they can be easily seen and read by Operators and Technicians. The legend should be close to valves or flanges and adjacent to changes in direction, branches, and where pipes pass through walls or floors, unless this shall result in excessive and/or ambiguous labeling. The Company permits practical variations in this case. For example, the placement of the legend in the middle of the visible length of pipe may be more in keeping with the purpose of pipe marking. Expert professional safe-practice shall always be observed in any variation.

6.2.1

Preventive Labeling Dangerous or hazardous products shall be labeled accordingly. All instructions shown on labels shall be brief, precise, and written in simple and easily understandable language. The language shall be practical, not based only on specific product properties, but used in a way to avoid risks resulting from the use, handling, and storage of product. Where there is a possibility of mixing 2 or more chemical products with properties different in type or degree from the individual ones, the label shall highlight the hazardous properties of the final product. The following items shall be included on the labels: •

Technical Denomination of product

•

Warning Word on the risk degree

•

Risk Indications

•

Preventive Measures including the ones that shall be in place

•

First Aid

•

Medical Information in case of accident

•

Special Instructions for fire, leakage or spillage, if applicable

Technical Denomination Note that the complete technical denomination, specifying nature of chemical product, i.e. “Corrosive Acid,” “Lead Based Product,” etc., shall be identified on the label. In any situation, the identification shall be such that the correct medical treatment can be chosen in case of accident.

Warning Words The following warning words shall be used: •

"PERIGO / DANGER” for substances presenting high risk

•

"CUIDADO / CAUTION" for substances presenting mild risks

•

"ATENÇÃO / ATTENTION" for substances presenting low risk

Risk Indication Indications shall inform about the risks related to normal or reasonably expected handling of the product. Examples: "EXTREMELY FLAMMABLE" or "HARMFUL IF ABSORBED THROUGH THE SKIN"

Preventative Measures Used to establish other measures to be taken to avoid harm or damages due to the indicated risks. Example: “KEEP AWAY FROM HEAT, SPARKS, OR FLAMES” and “AVOID INHALING THE DUST”

First Aid Should define specific measures to be taken before medical assistance is available. The size, style, and color of the letters and symbols should follow the ASNI / ASME 13.1 specifications for lettering and should be applied without variation as far as practicable. Refer to Section 6.7 for the recommended length of color field and size of legend letters in accordance with ASME A13.1.

6.3

PIPE LEGEND The legend shall be marked with the indication of flow direction. Additional details can be added to the legend at the Operators’ discretion. Such additions may include the line size, line number, and pressure rating. The direction of fluid flow under normal conditions shall be indicated by arrows stenciled adjacent to the legend in the same coloring as the legend. Where normal fluid flow may be bidirectional, such as on crossover lines, the flow direction shall be indicated with doubleheaded arrows.

6.4


MARKING FOR NON-INSULATED PIPING Firewater lines and other fire suppression fluid lines (e.g. CO2 and FM200) shall be painted with red (RAL 3020) along the entire length of the pipe according to Brazilian regulation NR-26 “Color Code for Safety”. All other lines shall be painted along the entire length.

6.5

MARKING FOR INSULATED PIPING Insulated lines shall be identified by color stripes taped to distinguish the system. The color is used to paint or affix a colored tape to the pipe at intervals along its length that are convenient to see from any area in which personnel circulate or may be found performing routine tasks. Maximum distance between color indicator stripe to be 8 meters. Color stripe width to be minimum 40% of the outside diameter of the pipe, but not to be less than 3 inches. For the pipe diameter less than 3inches, the width may be equal to the outside diameter.
