The acquisition will integrate PII’s outstanding PSM training, engineering, human factors consulting, management system implementation, and Safety Instrumented Systems verification capabilities with Trinity’s environmental consulting business, Trinity said.
“PII complements Trinity’s PSM capabilities,” Shishir Mohan, managing director at Trinity Consultants, said in a statement. “Bill Bridges and his team bring decades of applied experience, thought leadership and proven expertise in helping clients navigate complex industrial operations safely and efficiently.”
Mohan said the acquisition also strengthens Trinity’s ability to deliver advanced PSM services and training across North America, South America, Europe, the Middle East, and beyond.
Founded in 2003, PII helps organizations in highly regulated industries—including chemical, petrochemical, oil and gas, nuclear, pharmaceutical, semiconductor, and mining—solve their most complex safety, risk, and reliability challenges, Trinity said.
Expanding impact and expertise
PII’s experts have led thousands of process hazard analyses as well as hundreds of major incident investigations and process safety audits while building management systems, procedures, and risk-based safety methodologies tailored to their clients’ operations and culture, Trinity said. PII has conducted thousands of Layer of Protection Analysis and many thousands of SIL verifications.
PII’s instructors also have trained more than 10,000 professionals worldwide in PSM topics, including over 4,500 investigators, 5,000 PHA leaders, and 3,500 PSM auditors and experts, the company said.
“Joining Trinity allows us to expand our impact and offer higher-value services around the globe,” said Bridges, PII president and principal engineer. “As awareness of the business case for process safety and reliability increases across the oil and gas, pharmaceutical, semiconductor, and petrochemicals sectors, among others, this partnership strengthens our ability to help clients manage risk, improve reliability, and implement effective process safety systems worldwide.”
This acquisition builds on Trinity’s 50-year history of strategic growth, deliver new capabilities and expertise to clients while improving its ability to deliver safe, reliable and efficient industrial operations, the company said.
