Process Safety Engineering for Hydrogen Applications

Process safety engineering services

• Process safety is a key factor in the process and high hazard indus­tries. Based on a com­pre­­hen­sive and inde­pendent view we offer safety assess­ments and develop a basis of safety for your R&D and pilot units. We can provide semi-quantitative risk assess­ments & Hazard Studies, making sure that residual risk is accep­tably managed.
• Process and equipment safety and design of protec­tive systems and relief streams are firmly in our focus and inte­grated into the plant design from the very beginning onwards. Make use of our expe­rience and depth of know­ledge in the deve­lopment of R&D mini­plants and rigs either as a stand-alone engi­nee­ring service (deli­very of a design package) or as an integral part of an equip­ment/plant manu­fac­turing project together with our manu­fac­turing coo­pera­tion partners.
• Our process safety services can be applied to new units, review exis­ting units and modifi­cations/revamps of existing equipment. We advise on the choice, concept & detailed design of safety systems, including func­tional safety systems (SIL classi­fi­cation) and relief stream design. We can also support our clients with our exper­tise in the develop­ment & review of explosion safety assess­ments and area classi­fi­cations.
