Our recent projects

SCG performed dispersion calculations for a paper mill located in South Africa. These dispersion calculations used process data and local weather conditions to model the concentrations of releases from the vent stack. Sensitivity runs were also performed to show how changing parameters affected the dispersion. Ground level concentrations of several toxic chemicals were predicted, and contour maps were generated based on toxic exposure levels and odor thresholds. Recommendations were then made reduce the ground level concentrations which were then communicated to SAPPI.

SCG provides ongoing support in the updates to drawing files based on company MOCs. An SCG representative coordinates the updates to the drawings with our partner company, iFluids, in India. Drawing updates are performed and checked over by an SCG professional before being returned to the client for final approval.

SCG performed an EIA for a new piece of fired equipment for Boom Waste Management. Assessments to the site based on the addition of the kiln were performed by SCG staff including ambient air modelling, waste management and groundwater contamination.

SCG completed numerous loss prevention tasks for Parsons Marpol including the development of Fire and Gas Cause and Effect Diagrams, the Fire & Safety Philosophy, and Firewater demand calculations. SCG also facilitated HAZOP and HAZID workshops, developed layout drawings, and reviewed the HSE register.

SCG worked with Alcoa to develop their worldwide PHA program. This program included the implementation of LOPA covering all mining, refining, and smelting operations.

SCG performed a quantitative risk assessment for a Mina Petroeum storage terminal housing jet fuel and fuel naval distillate using PHAST software. In this QRA, best available industry data was used to calculate risk and recommendations were issued to reduce the likelihood and severity of the potential incidents.

SCG assessed and documented process areas in the Casa Grande HEXCEL facility. These areas included resin mixing rooms where chemical reactions, ventilation systems, and personnel activity were taken into account.

SCG Reviewed PSM practices and applicable documentation on site and provided recommendations to achieve full compliance with the OSHA PSM system.

SCG documented process information, vendor data, and other supporting information for relief valves located in several refinery areas. This data provided the basis for relief valve sizing calculations. Final documentation included required relief valve capacity, type, and size. Documentation also included inlet and outlet line pressure drops.

SCG provided workshop facilitators the North Field LNG Expansion project. Work included HAZOP workshop facilitation and SIL Assignment for both offshore units as well as onshore facilities.

SCG provided incident investigation services for a confidential client after two truckers were injured in a blast overpressure event. Based on interviews, physical evidence, and data logged by the computer systems, SCG developed a timeline leading up to the explosion, identified the most likely root cause, and analyzed contributing factors. SCG then provided expert witness services involving the development of a non-technical report to supplement the report created during the incident investigation.
