With the Transair Flow calculator you can now choose the best diameter based on your installation. Just enter the flow setting of your compressor f.a.d along with the pressure rating, the complete equivalent length of your system stating whether the system is a closed loop ring main or straight gun. A single click will then provide you with the best recommendation for the Transair diameter pressure with drops less than 5 %.

: The update provides refined compliance checklists for "hot" operations, including pressure limitations and material selection to mitigate the risk of burn-through or hydrogen cracking.
: Extensive rewrites were performed to align with IEC 61511-1 Edition 2 , reducing overlap and focusing on Shell-specific "essential additions" to the international safety standard.
Version 46 introduced several shifts in technical governance to align with international standards and improve operational safety:
Shell DEP Version 46, released in , is a comprehensive update to Shell’s Design and Engineering Practices (DEPs), specifically focusing on critical process safety and technical standardization across oil, gas, and chemical facilities. In this context, "hot" primarily refers to hot-tapping —a high-stakes engineering technique for making new piping connections while a system remains under pressure—and hot service operations. Key Updates in Version 46
The standard most closely associated with "hot" operations is , titled "Hot-Tapping on Pipelines, Piping and Equipment". Key requirements include:
: Shell DEPs are typically updated every February. Version 46 was the official 2022 issuance, superseded by subsequent versions like V47 (2023) and V48 (2024). Hot-Tapping Specifications (DEP 31.38.60.10)
