Free Oil and Gas: Strategy, Economics, Offshore, Subsea

Learn how petroleum economics informs value-driven decisions by quantifying design costs, risks, and cash flows across scenarios, shaped by fiscal regimes and robust assumptions.

Evaluate oil and gas projects with NPV, IRR, payback, and profitability index, recognizing no single metric suffices for the full economic picture. Discounting and project assumptions affect all four metrics.

Identify and analyze risk from scenarios and sensitivities, then act with four strategies: avoid, reduce, transfer, and accept, applying them to balance safety, cost, and project exposure.

Explore subsea high-integrity pressure protection systems (Hipps) that use three pressure transmitters, a two-out-of-three voting logic solver, solenoid valves, and fail-safe block valves to rapidly shut down on overpressure.

Explore flying leads, flexible connections that bridge the umbilical termination assembly to subsea structures, enabling power, signals, hydraulics and chemicals transfer while ensuring durability and easy underwater installation.

Explore the fabrication animation of subsea manifolds within offshore, subsea and ROV systems, highlighting fabrication processes and integration for offshore oil and gas operations.

Apply the ALARP principle, as low as reasonably practicable, to subsea risk by balancing cost, practicality, and regulatory requirements to reduce risks, not eliminate them, while following industry standards.

Use ultrasonic testing (UT) to measure wall thickness and detect flaws from corrosion and erosion. Apply magnetic particle testing (MPT) to reveal surface and subsurface cracks and inspect welds properly.

Learn the risk assessment process for subsea systems, identifying risks, building a risk register, and evaluating likelihood and impact using metrics, FMEA, and QRA to prioritize mitigation and inspection plans.

Learn the fundamentals of subsea RBI, including hazard and failure-mode assessment, observable underwater inspection parameters, and risk-ranked, baseline-based inspection planning.

Visualize hazards and risk pathways using bow tie analysis to map central hazards, causes, and consequences, and identify preventive and mitigative controls for subsea systems.

Trace the history and evolution of offshore, subsea and rov systems, from military unmanned vehicles to mature exploration tools, highlighting milestones like the 1966 first rov and 20,000-foot depth barrier.

Explore how remotely piloted and resident ROVs, enabled by 4G communication and surface-free operations, cut offshore costs, reduce vessel use, and enable rapid subsea responses.

Classify ROVs into five Norsk classes, from pure observation to development vehicles, and examine diverse applications across sectors amid the harsh subsea environment and costly remote operations.

Master pre-dive checks for ROV operations, inspecting frame, propellers, tether, and electrical connections to prevent offshore failures, and confirm safe startup, thruster function, and ballast before deployment.

Perform post-dive checks as a continuous baseline survey: inspect for damage, debris, and moisture; rinse salt water, re-test thrusters and lights, and securely store the tether and vehicle.
