P&IDs sit at the centre of operational, maintenance, and project decisions. Over time, modifications, upgrades, and maintenance activities create drift between drawings and the physical plant. When records no longer reflect reality, or when authorised changes are not clearly incorporated — confidence erodes and risk increases.
This solution exists to restore that confidence. Phase supports asset owners and project teams by verifying that P&IDs align with physical reality and authorised change, providing records of what was checked and what differs, for high-consequence environments — offshore and onshore alike.
P&IDs change constantly, but records rarely keep pace. Modifications are made offshore and onshore, maintenance work introduces undocumented changes, and project updates are captured inconsistently or late. Over time, drawings drift from the physical plant, creating uncertainty about what actually exists.
In high-consequence environments, that uncertainty matters. Engineers are asked to plan work, approve changes, or sign off activities using drawings that may be incomplete, mis-tagged, or based on assumptions. Informal mark-ups, inconsistent standards, and unclear ownership of updates compound the problem. The result is hesitation, rework, and exposure — often discovered too late, when questions are hardest to answer.
P&IDs and associated records are checked against the plant, however each update originated. Coverage is adapted to the asset, governance model, and level of assurance required, but typically includes verification across the following areas.
This solution is applied at different entry points, depending on asset type, governance, and the level of assurance required. The examples below illustrate how verification is typically applied in practice — showing how authorised change, physical reality, and higher-consequence updates are reconciled and confirmed before records are issued under control.
P&ID verification is not a one-time exercise — it is a response to the reality that drawings drift from physical plant over time. Phase establishes the current state of records against physical conditions and authorised change, providing asset owners and project teams with a verified baseline for operational decisions, modifications, and regulatory requirements.
Phase operates from Aberdeen, supporting P&ID and asset verification across offshore and industrial facilities throughout Scotland and the UK.
