Subsea Wellhead Integrity Monitoring – SWIM™
No More Blind Spots. Just Trusted Wellhead Data.
SWIM™ measures accumulated load and other critical wellhead parameters during drilling operations, offering KPIs and predictive analysis as a digital service – without the need for extra personnel on the rig.

The Old Way
- No reliable decision support for when to disconnect or continue drilling in bad weather — teams are left without the data they need.
- No simple way to install a sensor system that signals possible loss of well integrity while drilling.
- Conservative assumptions are used in analyses instead of real sensor data, potentially preventing or complicating planned operations.
- No good, simple method to record the actual loading on a well over its life.
The SWIM™ Way
SWIM™ provides a well-documented solution for monitoring the main barrier while drilling, with extensions for real-time monitoring of drilling risers and conductors. Powered by machine learning and artificial intelligence, SWIM™ detects and manages issues like shallow gas/water, structural wellhead failures, and conductor instability.
With SWIM™, operators can optimise well reuse and maximise wellhead life. Predictive models and accumulated wellhead load data support scheduling and operational decisions based on weather forecasts and well criticality.
- Results are presented live on a web application accessible to the rig crew and the land organisation
- Onshore wellhead specialists can support decision making during the drilling campaign as requested
- Measured data are stored and can be re-used for model calibration
- The system can be attached to the rig pod umbilical
Key Benefits
By providing continuous, real-time data on wellhead conditions, SWIM™ helps operators make informed decisions, prevent costly interventions, and extend asset life.
-
Real-time tracking of stability, load, fatigue, and structural integrity for subsea wellheads.
-
Decision support helps drilling teams know when to disconnect in adverse weather conditions.
-
Extends the life of wells with wellhead integrity concerns by enabling safer and more controlled operations.
-
Data is accessible via a web application for both rig crews and onshore teams, ensuring seamless communication and collaboration.
-
Provides live readings at any depth without requiring an ROV, reducing operational complexity.
-
Confirms the wellhead’s functionality after drilling operations, supporting long-term well integrity.
-
Can be deployed for exploration, greenfield, and brownfield wells.
Enhancing Safety in Drilling Operations
When AkerBP encountered an unexpected washout incident three days into drilling a satellite production well, BOP movements and soil erosion raised immediate concerns about structural integrity. By integrating SWIM™ measurements with detailed simulations, 4Subsea defined a safe window of operations and supported mitigation measures including gravel dumping and installation of Wellhead Load Reliefs. AkerBP successfully completed drilling and transitioned the well to production.
client testimonial
“The swift and professional response of a team of experts from 4Subsea gave us a clear picture of the actual condition on the wellhead after the incident, allowing us to come up with an effective plan of mitigation actions and giving us confidence that after the implementation of the mitigations we could finish the drilling campaign and deliver the well to the asset in a safe manner. This was a serious incident, without data and expert competence there was a real risk of having to re-spud the well, implying in significant additional time and costs.” Rafael Rossi,
