Rig-to-subsea operations bring together equipment, handling systems, and interfaces across the rig floor, drill floor, moonpool, and subsea environment. Each element must align precisely for deployment to proceed safely and without late-stage discovery.
Phase is engaged early to verify whether a campaign will physically work on a specific rig, with defined equipment and known constraints. By establishing the rig geometry from measured reality and assessing interfaces end-to-end, Phase enables teams to identify and resolve issues onshore — before they become offshore problems.
Rig-to-subsea campaigns operate within tight physical limits and limited tolerance for error. Deck space is constrained, height envelopes are fixed, moonpool geometries vary by rig, and subsea interfaces must align exactly during deployment.
Clashes frequently arise from deck congestion, door and carrier restrictions, drill floor handling paths, drill string stack-ups, umbilical routing, or subsea interface geometry. When these issues are not identified early, they surface offshore — where time, cost, and recovery options are limited and consequences escalate quickly.
Phase provides decision-support through physical verification.Establishing the rig geometry from measured reality, introduces campaign equipment, and assesses how items are landed, stored, handled, routed, lifted, deployed, and interfaced subsea. Where constraints or clashes are identified, they are resolved through verified layouts, interface definition, and the design of skids, frames, seafastening, and handling aids — all issued through controlled review processes aligned with rig and operator governance.
The following verification work is applied to confirm physical feasibility and interface compatibility across the rig, handling system, and subsea environment. Outputs are used by subsea and drilling teams as evidence during readiness reviews and campaign planning.
By verifying rig layouts, handling paths, and subsea interfaces as one connected system, Phase enables teams to remove physical uncertainty before mobilisation.
Phase outputs are routinely used by subsea and drilling teams as clear, defensible evidence during internal reviews and campaign readiness meetings — helping teams demonstrate that physical risks have been identified, understood, and addressed before offshore execution.
The result is fewer surprises, stronger alignment across stakeholders, and campaigns that proceed on verified reality.
Phase operates from Aberdeen, supporting rig floor to subsea verification across North Sea campaigns and international offshore operations.
We have delivered campaign sequencing animations and deployment visualisations for major operators, drilling contractors, and subsea service companies across the North Sea since 2020 — including subsea equipment sequencing, rig-up simulation, and deployment visualisation across multiple campaigns and vessel types. Each engagement follows the same approach: real equipment geometry, verified platform environment, accurate sequences reviewed and agreed before mobilisation is committed.”
