SURVEY QUESTIONAIRE – FOR SELECTION THE LONG LIST BIDDER OF “ENGINEERING, PROCUREMENT, INSTALLATION, COMMISSIONING FOR MOC-REPLACE SDO-0824 BY SDOL-0424 IN SIS SYSTEM” PACKAGE

Date: 24-Feb-26, Rev. 0

Nghi Son Refinery & Petrochemical Limited Liability Company (NSRP) is planning for the procurement of EPCC for MOC-REPLACE SDO-0824 BY SDOL-0424 IN SIS SYSTEM.

If your company is interested in those procurement packages, please fill in and complete the questionnaire below then send email to giang.vt1@nsrp.com.vn

Subject: “Respond for Questionnaire – MOC-REPLACE SDO-0824 BY SDOL-0424 IN SIS SYSTEM” by 17:00PM 06 March 2026 at the latest.

1. Project introduction

The NSRP Safety Instrumented System (SIS) is designed to perform Safety Instrumented Functions (SIFs), including plant or unit shutdown, depressurization, equipment protection, and equipment isolation during abnormal or hazardous conditions. The SIS is designed as an independent, fail-safe, and fault-tolerant system using high-reliability and high-availability hardware. Based on the Honeywell Safety Manager platform, the system is developed in accordance with IEC 61508 and is TÜV-certified for SIL 1 to SIL 3 applications.

There are some UZV valves that installed 2 solenoids (with voting 2oo2) to increase reliability and SIL of the SIF loop. The Valve open/close commands are provided by the SIS Safety through Digital Output module (SDO-0824), which does not include output line monitoring.

Since the SDO-0824 module does not have a line monitoring function, it can’t detect leakage or open-circuit failures. If a solenoid has already failed, the system will be unable to detect it.

To address this limitation and increase reliability of the SIF, NSRP wants to replace the existing SDO-0824 modules with SDOL-0424 modules that support output line monitoring. This enhancement will enable the detection of open-circuit and short-circuit conditions in the solenoid valves, allowing proactive maintenance planning and reducing the risk of nuisance trips.

2. General Scope of Work

The project scope includes Engineering, Procurement, Installation, and Commissioning services, including:

• Detailed engineering design, site surveys.
• Procurement of SDOL-0424 module, Output converter modules, Field Terminal Assembly module, system interconnection cables, and accessories.
• Software modification systems.
• Remove the existing modules, field terminal assembly module and system interconnection cable with certified manpower in local rules and international rules.
• Re-arrange and optimize the channels for the Emergency Shutdown valve.
• Installation of the new modules and cables to the system with certified manpower in local rules and international rules.
• Implement Final Acceptance Test (FAT)/ Site Acceptance Test (SAT).
• Commissioning includes function testing and verification.
• Supervising and coordination with relevant authorities.
• Documentation, and handover to NSRP Operations.
