Conducted risk assessment on an 18" subsea pipeline from BPJT-A to BTJT-A and BPJT platform, evaluating structural integrity and third-party interference (TPI) risks including drop anchor impact and pipe-laying-on-abandoned-pipe scenarios per ASME and DNV codes. Performed structural modeling in ANSYS Static Structural for static analysis and LS-DYNA for dynamic analysis of drop and drag anchor, in

Analyzed sedimentation, tombolo, and salient formation around offshore breakwaters using CFD (Volume of Fluid modeling) to simulate sediment transport and coastal morphology changes. Assessed pile and breakwater structural integrity under wave loading using the Morison equation.

Performed Risk-Based Inspection (RBI) and risk analysis on HCML's subsea pipeline network using ANSYS FEA, evaluating structural and corrosion risk to inform inspection prioritization.

Conducted root cause analysis of BD GMS pipeline failure combining ANSYS Mechanical FEA modeling with field measurement data, for Husky-CNOOC Madura Limited (HCML). Identified [failure mechanism/contributing factor] and recommended [mitigation/inspection interval].

Modeled scour development and vortex-induced vibration (VIV) risk along a 2M subsea pipeline section using CFD, for HCML. Delivered predictions used to assess span integrity and prioritize remediation.

Worked as Operations Analyst at PT Berlian Jasa Terminal Indonesia - BJTI PORT (PELINDO Group).

Thesis: "Numerical and Experimental Study of the Performance of Wave-Absorbing Beaches as Passive Wave Absorber."
Conducted at the ITS Ocean Engineering department, this research focused on evaluating wave absorber performance in a flume tank using Smoothed Particle Hydrodynamics (SPH) modeling via DualSPHysics.
