EVXT TM Exercise:
Scenario: You are working on a subsea project involving the installation of an EVXT TM for a deepwater well. You need to consider the key factors that will impact the success of the installation process.
Task: Identify at least three key factors that should be carefully considered during the EVXT TM installation, explaining why they are crucial for a successful project.
Exercice Correction
Here are three key factors to consider during EVXT TM installation:
- **Water depth and environmental conditions:** Deepwater installations present unique challenges due to pressure, currents, and visibility. Careful planning and specialized equipment are necessary for safe and efficient deployment.
- **Precise positioning and alignment:** The EVXT TM must be precisely positioned and aligned with the wellhead to ensure a secure connection and optimal flow. This requires advanced subsea positioning systems and meticulous execution.
- **Integration with existing subsea infrastructure:** The EVXT TM must seamlessly integrate with existing pipelines, manifolds, and control systems. This involves careful planning, compatibility testing, and potentially modifications to the existing infrastructure.
