QUALITY DELIVERED... SAFELY, ON TIME, EVERY TIME
MSL Engineering Ltd. is a full-service mechanical engineering contractor operating across a wide range of industry sectors. With over 45 years of expertise and a flexible project management approach, MSL delivers best-in-class projects utilizing BIM and modular fabrication processes to the highest standards of workmanship, safety, quality, and reliability.
Founded in 1979, MSL Engineering specializes in the fabrication and installation of process, utility, and high-purity pipework, platforms, steelwork, and equipment installation across many industry sectors.
Service Offerings:
- Modular fabrication and assemblies
- Fabrication and installation of process, utility, and high-purity pipework
- Managing multi-discipline subcontractors including HVAC, scaffold, craneage, insulation, painting, and NDT
- Utilizing BIM and 3D modelling design processes
With a workforce of over 700 people, MSL has grown to become one of the leading players in an industry that has seen parallel growth in the pharmaceutical, biopharma, semiconductor, chemical, oil and gas, energy, data centre, and food & beverage sectors.
Originally established to provide craft support to the fledgling but now defunct NET plant in Marino Point, Cork, the business expanded its client base over time and developed a reputation for reliability, engineering excellence, and the ability to get the job done.
Retaining the roots of the original founders, the company is a wholly owned Irish entity. It has organically evolved from providing support services to local industry to a position where it now competes successfully for large-scale engineering projects and provides a full range of engineering and constructability solutions to clients throughout Ireland, the UK, Europe, and the US.
Safety Commitment: Working in inherently hazardous industries, MSL has always taken an uncompromising approach to safety. This is evident in its high standards and long-standing safety record, its ISO45001-accredited safety management system, and its behavioural safety-based systems of work.
MSL’s desire to continuously improve to stay ahead of the competitive curve has led it to identify and invest in new business processes in recent years. As a result, the company significantly increased turnover and expanded its area of operation to include Denmark, Belgium, the Netherlands, Switzerland, Sweden, and the UK.
Digital Technologies Investment: The company’s investment in digital technologies means MSL continuously improves its BIM offering to clients and its digital project delivery (DPD) capabilities. MSL also encourages and promotes early contractor engagement and an integrated project delivery (IPD) approach by offering modular design and modular construction experience to maximize offsite manufacturing and fabrication (OSM) opportunities for clients.
Recently, MSL has successfully demonstrated its ability to execute an “OSM Integrator” role on significant CAPEX projects of scale, by coordinating between client, designer, and contractor, and capitalizing on any potential value added by OSM and a modular approach.
Reflecting strong growth, MSL has invested in a modern 140,000 sq. foot fabrication facility in Ringaskiddy, Co. Cork. This new facility, adjacent to the newly relocated Port Of Cork, includes a large-scale modular fabrication workshop, a piping fabrication workshop, and an 8,000 sq. foot clean piping workshop. It enables MSL to continue to service all their existing clients and allows them to expand and develop relationships with new clients in Ireland and abroad.
MSL Managing Director Brian McGrath says: “Our mission is to set the industry standards for safety, quality, and reliability, consistently exceeding client expectations. Guided by honesty, respect, and integrity, we are dedicated to forging enduring partnerships that deliver mutual benefit and success for our clients, team, and community.”
“Our focus in developing a standard of performance is to ensure all MSL personnel are empowered to achieve their full potential and are recognized for doing so. Our performance standard defines how well each function or task must be performed in order to meet or exceed expectations, thus ensuring our standards are best in class.”
With continued growth, a new modern Fabrication Facility, ISO accredited Management Systems in Safety (ISO45001), Quality (ISO9001) & Environmental (ISO18001), and investment in new innovative business processes, MSL Engineering Ltd continues to challenge itself to deliver the highest standard of service deserved and expected by its clients.
