Subsea Intervention Engineer

Position Overview

The Subsea Intervention Engineer plans and executes light well intervention (LWI), riserless light well intervention (RLWI), and rig-based intervention campaigns on subsea wells. This role is central to maximising production from existing subsea assets without the cost of full rig mobilisation. As operators shift from drilling new wells to managing and enhancing existing ones, intervention engineers have become indispensable.

Key Responsibilities

• Plan and engineer subsea well intervention campaigns, including slickline, e-line, coiled tubing, and wireline operations.
• Develop intervention programs, risk assessments, and contingency plans for subsea well access.
• Specify and coordinate intervention vessel spread requirements (Monohull LWI vessel, DSV, or rig-based).
• Interface with well services, completion, and production teams to define intervention objectives and success criteria.
• Oversee the deployment of intervention workover control systems (IWOCS/DTI) and landing strings.
• Manage real-time decision-making during offshore intervention operations, including barrier verification and well control.
• Prepare post-intervention reports, lessons learned, and updated well integrity status documentation.
• Coordinate with subsea controls engineers for tree re-entry, valve manipulation, and SCM diagnostics during interventions.
• Evaluate and qualify new intervention technologies (e.g., through-tubing rotary drilling, subsea lubricator systems).
• Support production enhancement studies and candidate well selection for intervention campaigns.

Qualifications

Required

• Education: Bachelor's degree in Petroleum, Mechanical, or Subsea Engineering.
• Certifications: BOSIET/FOET with CA-EBS; IWCF Level 3 or 4 (Well Intervention Pressure Control preferred); Offshore Medical.
• Experience: 8–15 years in subsea well intervention, with direct offshore campaign execution experience.
• Technical Skills: Proficiency in intervention program design; deep understanding of subsea tree interfaces and IWOCS/DTI systems; well control competency for intervention operations.

Preferred

• Experience with riserless light well intervention (RLWI) from monohull vessels.
• Familiarity with subsea lubricator and horizontal tree intervention systems.
• Track record of managing multi-well intervention campaigns.
• IWCF Well Intervention Pressure Control certification.
