Overview

I’m a mechanical engineer with 22 years of working experience, 15 of them as a subsea pipeline engineer.

I have experience in designing subsea pipelines, inclusive of lateral buckling and pipeline walking (using ABAQUS), on-bottom stability, free span, vortex-induced vibrations, fatigue and fracture mechanics (ECA).

I understand and am able to write the scope of work, technical specifications, design basis and design reports for conceptual, FEED and detailed design, having worked on major projects such as TOTAL’s Egina, Chevron’s Gendalo Gehem and Wheatstone, INPEX’s Ichthys Phase 1, Reliance’s KG-D6 and ONGC’s KG-D98.

I have considerable experience in Finite Element Analysis (FEA) having started my career with the FEA companies serving companies in various engineering industries (biomedical, semiconductor, aerospace, automotive). I am proficient in ABAQUS, ANSYS and MSC.Sofware.

My current focus is on lateral buckling, pipeline walking and fracture mechanics (ECA) of subsea pipelines for normal and sour service.

I have also spent 2 years working on solving vibration, fatigue and fracture issues in the mining industry in Western Australia. I have performed pressure vessel verification as per ASME VIII.

I am well versed with the Australian, DNV, BS7910 and ASME VIII standards.

I am a registered member of the Institute of Engineers Malaysia and Engineers Australia, and am working towards my Chartered Engineers status.

I have legal rights to work in Malaysia and Australia.

PROJECT EXPERIENCES

McDermott Asia Pacific

Location: Kuala Lumpur, Malaysia
Position: Principal Subsea Engineer
Duration: September 2018 – present

I am part of the advance analysis team focusing on nonlinear applications in subsea engineering. Besides lateral buckling analysis, I am currently focused on Engineering Critical Assessment (ECA) of welded structures (fracture mechanics).

Tortue, BP
Lead ECA Engineer

I lead a team of engineers that are performing the 3D ECA analysis of the girth welds for this project. The pipeline will be installed via the Amazon. This is a J-lay process. The fatigue crack growth is performed using CrackWise but the end of life fracture is done using 3D FEA. The analysis was performed for CRA clad pipes.

Sepia, Petrobras
Lead ECA Engineer

I lead a team of engineers that are performing the 3D ECA analysis of the girth welds for this project. The pipeline will be installed via the NO105. This is a reel-lay process. The ECA involves 3D FEA for the tearing assessment during the reeling cycles, followed by fatigue crack growth using CrackWise and finally the end of life fracture assessment via 3D FEA. The analysis was performed for MLP pipes.

KG-D98, ONGC
ECA and Reeling Assessment

ECA analysis of carbon steel pipelines using the FAD approach. Sour service.
Also modelled and analysed the pawn head and pipe strength mismatch during reeling of the linepipe onto the reel.

Stonefly Subsea Development Pipeline Installation, LLOG
ECA Engineer

ECA analysis of the carbon steel pipelines. FAD approach.

Lucious Hadrian Subsequent Development Project
ECA Engineer

ECA analysis of the carbon steel pipelines. FAD approach.

KG-D6, Reliance
Buckling and Walking Engineer

Analysis of anchor collar under installation loads using nonlinear analysis when the linear analysis performed by the vendor was inadequate.

Also anslysed pipeline walking and used a synthetic rope as a walking mitigation measure instead of a chain in order to avoid slackening of the chain due to corrosion.

Performed a nonlinear buckling assessment to determine the buckling capacity of a partially buried pipeline initiation suction pile that didnt embed deeply into the soil.

• Engineering of an underground maintenance working platform for BHP Nickel-West mining shaft
This seven-month project was to design and engineer a man-cage and a skip-style working platform that could be deployed in a 1.2 km deep underground mining shaft for workers to replace brackets and bunton beams. Work was done as per the underground conveyance mining code and involved extensive FEA and supported by engineering calculations (as per client’s requirements). This platform includes foldout roofs and platforms that were gear driven to enable workers to reach the corners of the shaft. This project was successfully completed with the skip-style working platform currently being fabricated.
