LA SEGURIDAD DE SUS GASODUCTOS

Entienda las señales de fuga en un gasoducto

Las fallas de los sistemas de gasoductos son muy infrecuentesdebido a los estrictos procedimientos de mantenimiento e inspecciónempleados por CIG y la industria de los gasoductos. Sin embargo,recuerde que cualquier fuga en un gasoducto puede ser peligrosa.Manténgase alerta a las posibles señales de fuga en un gasoducto:

• Un sonido de soplido o silbido

• Polvo que sale de un agujero en el suelo

• Expulsión de agua, burbujeo continuo o una capa brillosa deaceite en áreas mojadas o inundadas

• Olor a gas, a hidrocarburo u otro olor inusual

• Una sección de vegetación seca o descolorida en medio de unárea verde

• Llamas, si la fuga se encendió

Actúe de inmediato si sospecha que hayana fuga

Muchos gasoductos contienen productos incoloros e inodoros queson altamente inflamables. Si reconoce alguna de las señales indicadas a la izquierda, usted:

• Debe evitar las llamas expuestas u otras fuentes de ignición

• No debe poner en marcha ni apagar los vehículos motorizados oel equipo eléctrico (incluso conmutadores y teléfonos)

• Debe abandonar el área e intentar prevenir la entrada de personas desprevenidas

• Debe abandonar el equipo que se esté utilizando en o cerca delárea

• Una vez que se encuentre a una distancia segura, debe notificarde inmediato a la compañía propietaria del gasoducto para queésta verifique la fuga y tome las medidas correctivas necesarias

• Si no sabe cuál es la compañía propietaria del gasoducto, llameal 9-1-1 o comuníquese con el departamento de bomberos, lapolicía o el aguacil local e indique la ubicación y naturaleza delproblema

• Debe solicitar ayuda de las autoridades policiales locales paraaislar el área

En Colorado Interstate Gas Company (CIG), estamos comprometidosa la seguridad. Como líder de la industria en el transporte de gas natural, tomamos muchas medidas para mantener la integridad denuestro sistema de gasoductos.

Gasoductos con materiales de alta resistencia yprotección contra la corrosiónA lo largo de todo nuestro sistema, utilizamos gasoductos quecumplen o exceden las normas establecidas por la industria del gasnatural y el gobierno federal. En áreas pobladas, instalamos gasoductos de paredes más gruesas para ofrecer un nivel de

protección aún mayor contra las perforacionesy la corrosión.

Todos nuestros gasoductos están revestidos con material especial que ayuda aprevenir la corrosión. Durante la construcción,se aplica un revestimiento protector alrededorde cada soldadura antes de tender el gasoducto en el suelo. Además, se extraen loslíquidos de hidrocarburos, dióxido de carbono

y agua en las plantas de procesamiento para producir gas natural decalidad para gasoducto y para proteger el gasoducto contra los efectos corrosivos de estos contaminantes. Se utiliza proteccióncatódica para suprimir los efectos corrosivos en el suelo, tal como lorequiere el Departamento de Transporte de Estados Unidos.

Pruebas e inspecciones de rutina Realizamos inspecciones y pruebas regulares de nuestros gasoductospara identificar posibles áreas problemáticas. Una de las pruebasrealizadas antes de iniciar las operaciones es la prueba hidrostática.Para determinar si hay secciones débiles en la tubería, se llenan con

agua algunas secciones de la misma yluego se presurizan con presionesmucho más altas que la presión deoperación normal de la tubería.

También realizamos inspeccionesde rutina a lo largo de nuestro sistema degasoducto. Durante la construcción, realizamos pruebas no destructivas decada tubo soldado para verificar quetodas las soldaduras satisfacen las

exigencias de las normas. Una vez que el gasoducto está enoperación, realizamos una inspección visual aérea y terrestre manejando a lo largo del derecho de paso del gasoducto paradetectar cualquier evidencia de erosión del suelo, derrumbamientode tierra, trabajos de construcción o excavación, o cualquier otracosa que pudiese dañar el gasoducto y afectar la seguridad de suoperación. Además, observamos los sistemas que ofrecen protección contra la corrosión a nuestros gasoductos.

Operaciones y monitoreo sofisticados de nuestros gasoductosPara garantizar la operación segura de nuestro sistema de gasoductos,empleamos técnicos altamente capacitados y especializados paraoperar el sistema de acuerdo con los reglamentos gubernamentales

federales, estatales y locales. Cada profesional comparte el compromiso de CIG de mantener la seguridad del entorno de opera-ciones.

La operación segura del sistema es nuestra consideración principal. Esto es evidente por la forma en que observamos y

controlamos el transporte por gasoductodel gas natural. Regulamos con alta precisión la presión del gas dentro de loslímites establecidos por el Departamentode Transporte de Estados Unidos, paramantener la integridad y garantizar elfuncionamiento confiable y seguro delsistema de gasoducto.

Las estaciones de compresores a intervalos a lo largo del sistemade gasoducto están equipadas con varios dispositivos de seguridad.Uno de estos sistemas de seguridad, el cual es común a todas lasestaciones de compresores, es el sistema de paro de emergencia.Cuando está activado, el sistema de paro de emergencia detiene losmotores, aísla y ventila las tuberías de compresores y dirige el gaslejos de la estación.

Si la presión dentro del gasoducto cambia en algún momento,se alerta de inmediato a nuestro centro de control de gas. El centroestá diseñado para observar y controlar el sistema completo degasoductos las 24 horas, 365 días por año, mediante sofisticadoequipo de computación y telecomunicaciones. Si se detectan fluctuaciones de presión anormales en cualquier sección a lo largodel gasoducto, el centro de control toma las medidas apropiadas, lascuales podrían incluir desviar el flujo de gas alrededor del área delproblema o aislar en forma selectiva secciones del gasoducto paracambiar la trayectoria del flujo de gas. De esta manera, se mantienennuestras altas normas de seguridad con un efecto mínimo en el servicio a nuestros clientes.

Programas de concientización públicaJunto con todo lo que hacemos en CIG para operar en forma seguranuestro sistema de gasoductos, también necesitamos la ayuda delpúblico. Con ese fin, hemos establecido un extenso programa paraasegurar que el público esté informado acerca de nuestro gasoductoy pueda ayudarnos a mantener su funcionamiento con el menor riesgo posible.

Trabajamos con compañías de construcción locales y con propietarios de terrenos cercanos al gasoducto, y les proporcionamosinformación importante acerca de la ubicación del gasoducto, procedimientos de emergencia, y los nombres y números de teléfonosde nuestros empleados clave.

Además, identificamos la ubicación de nuestros gasoductoscon marcadores, banderas o letreros. Proporcionamos informaciónsobre dónde y a quién llamar en caso de una emergencia o si esnecesario excavar cerca del gasoducto. Cualquier persona quenecesite realizar actividades de excavación debe notificar la ubicación exacta de una excavación planificada al Centro deLlamada Única (One Call Center) estatal. Dicho centro contactará alos operadores del gasoducto, quienes enviarán un representantepara marcar las tuberías en las inmediaciones de la excavación.
