Rugged offshore construction:

Utilizes only proven design and reliable components.

·  Material used is 316 stainless steel construction (unless otherwise indicated).

·  Panels are fabricated from 316 stainless steel, with minimum 3 mm thickness.(Painting applies where applicable.)

·  Well organized layout and extensive component tagging simplify operation and servicing.

·    Component tagging is cross-referenced to drawings for fast troubleshooting. Schematics use easy-to-read modified ISA symbology.

·  Provides a fail-safe shutdown of wellhead surface valve, SSV (Master/Wing Valves) in the event of a hazardous and/or abnormal operating conditions.

·  Provide a fail-safe shutdown of wellhead sub-surface safety valve, DHSV (Down hole Valves) in the event of hazardous and/or abnormal operating conditions.

·  Panel logic is designed with the first-out indication logic.

·  Properly sized distribution header for Instrument Air and Hydraulic Supply.

·  Fittings are AISI 316 Stainless Steel, double ferrule compression Swagelok type.
