New Boil-Off Gas Compressor Project – LOPA/SIL

Project Details

Title: New Boil-Off Gas (BOG) Compressor Project

Client: NLNG

Location: Bonny Island

Date: 2021

The project involved the Detailed Engineering Design (DED) of the expansion the existing Boil-off Gas Compressor in the existing NLNG facility at Finima in Bonny Island.

SIL (Safety Integrity Level)
The SIL (Safety Integrity Level) determination workshop for the New BOG Compressor Project was performed in line with DEP 32.80.10.10-Gen and IEC 61511. The workshop assessed each SIF (Safety Instrumented Function) for SIL.

Objectives:
⦁ Critically analyze each H & RA scenario to determine the risk it presents
⦁ Identify all available protection layers and the risk reduction levels
⦁ Determine the need for a SIF
⦁ Determine the risk reduction levels needed and assign a SIL level to the SIF, if
⦁ required
