1 INTRODUCCION

La coordinacin de Ingeniera Mecnica tiene la responsabilidad de hacer lasespecificaciones, requisiciones y seguimiento de fabricacin de los Hornos deProceso.

Se debern aplicar los procedimientos generales establecidos en suorganizacin para requisitos de equipos, anlisis de ofertas, compra yseguimiento.

2 PREPARACION DE ESPECIFICACIONES DE DISEO

Se deber usar la Especificacin de Ingeniera PDVSA B201PR,

Calentadores de Fuego Directo.

3 INFORMACION SOBRE PROCESOS

La informacin sobre procesos le ser facilitada al Ingeniero de Proyectos por el

Ingeniero Jefe de Procesos. El Ingeniero Jefe de Procesos deber enviar una

comunicacin interna al Gerente de Proyectos estableciendo los criterios y

parmetros de diseo para los calentadores.

4 DISEO MECANICO DE LOS HORNOS

El diseo mecnico de los hornos estar a cargo del ingeniero especializado bajo

la supervisin del Gerente de Proyectos. El especialista deber llenar las Hojas

de Datos correspondientes a los hornos de proceso. Las Hojas de Datos definen

claramente las responsabilidades de cada una de las partes involucradas en el

diseo, fabricacin, inspeccin, suministro y aprobacin de los equipos. Toda

informacin sobre procesos o cualquier caracterstica mecnica que se necesite

se deber incluir en las Hojas de Datos. Las caractersticas mecnicas a que esto

se refiere sern las limitaciones especiales que pueden emerger en un proyecto

particular tales como, limitaciones del terreno, altura de las chimeneas,

localizacin de plataforma, normas locales especiales, etc.
