PROFESSIONAL EXPERIENCE:

Mechanical Engineer (Offshore Engineering) – Foster Wheeler USA (Upstream) and OPE Inc., Houston, TX

2007 to Present

• Pipeline Collapse/Buckling Analysis (Global Industry): Pipeline (up to 42" OD) buckling and post-

buckling behavior was examined in ABAQUS based on eigenmode and non-linear Riks (Arc-length) method.

Overbend and Sagbend regions were carefully examined. Shell element was used for highly efficient FEA

procedure. Stinger roller box was included in FEA model and different stinger sizes were used. Pipe ovality,

wall thickness tolerance and diameter tolerance were all examined. DNV and API codes were used as

integrity check criteria.

Chinook, Helix): Vortex induced vibration screening and maximum allowable span analysis. Extensive

current and wave induced fatigue analysis for a number of pipeline and subsea systems based on DNV F-

105 and DNV C-203.

• Pipeline Installation (J-Lay & S-Lay) FEA Analysis (Williams Energy): ABAQUS was used to examine

pipeline installation through overbend (on stinger) and sagbend regions, in both deep and shallow water. 3-D

pipeline model was created to evaluate local high stress/strain. Different types of stinger sizes, roller box and

seabed were modeled. Integrity was checked with DNV code.

• Murphy Thunder Hawk PLET Design and Installation Analysis (Helix Energy Solution): Performed 3-D

Oil/Gas Export PLET (8”, 12” and 20”) installation analysis in ABAQUS. Detailed bending strain and stress

distribution on PLET was reached, different center gravities for PLET were examined and installation

guideline was provided.

• BP-Cameron GoM PLEM and ILS Installation Analysis (BP, Cameron): Performed 3-D PLEM and ILS

installation analysis in ABAQUS. Detailed bending strain and stress distribution on PLET was reached,

different CG for PLEM and angle of rotation were examined and installation guideline was provided.

• BP-Cameron GoM PLEM and ILS Detailed Stress Analysis (BP, Cameron): Detailed 3D stress analyses

were performed for PLEM and ILS in ABAQUS by using both SOLID and SHELL element. Also, Structures

under different loading conditions were analyzed, including Inplace, Lifting, transportation, and etc.

• Apache Van Gogh PLEM Design and Loading Analysis (Cameron): 2-D piping analyses for PLEM were

performed in ANSYS with structural and thermal load matrix applied. For high stress/strain regions, 3-D

PLEM model in ANSYS was created for detailed FEA analysis. Von Mises, Hoops and Longitudinal stresses

were checked with ASME code.

• Perdido Norte Oil/Gas IVA Installation (Williams Energy): Performed extensive 3-D Finite Element

Analysis in ABAQUS for in-line Valve and in-line tee structures along with 2,500 m long pipeline system

during deepwater Installation (1,680 m in water depth, J-Lay and S-Lay). A 108 m stinger was used at

overbend & buoyancy module was used at Sagbend. Linear and nonlinear analyses were both performed.

• Dynamic Drilling Well Modeling (BP): Long pipeline (5000 m) was abandoned and dynamic load to the

well packer was evaluated using FEA analysis (ABAQUS). Pipe-in-Pipe element was used to model the

contact between the tubing and the guide casing. Nonlinear material was included and actual well system

configuration was modeled. Maximum dynamic load to packer was checked against packer’s design limit,

and the tubing integrity was evaluated during dynamic modeling.

• Pipeline and Subsea System Installation FEA Modeling (Williams Energy): Developed a number of 2-D

and 3-D FEA models in ABAQUS for pipeline installation through overbend (stinger) and sagbend. Roller

box was modeled in accordance with real stinger. Different installation procedures (buoyancy module,

bottom tension, etc) were examined. Local strain/stress concentration and installation guideline was found to

maintain structure integrity.

• Murphy Thunder Hawk Pressure Vessel Design (Helix Energy Solution): Performed detailed structure

stress/strength analysis in ABAQUS for high pressure vessel. Various designs were considered to achieve

the optimum structural strength.

• Umbilical Reel Equipment Stress Analysis (Helix Energy Solution): Performed nonlinear stress/strength

analysis for large scale umbilical reel structure (800 Te load capacity) under various boundary and loading

conditions.

• Umbilical Cable (1000 m) Recovery from Seabed (Helix Energy Solution): FEA Modeling (ABAQUS) for

umbilical pulling was performed to simulate the lift of long heavy umbilical cable through J-tube. Anisotropic

friction factors (i.e., tangential and lateral) between the seabed and cable are modeled differently. Axial,

bending and torsional stiffness for umbilical cable was specified. Buoyancy modules were suggested based

on FEA results.

• Umbilical Cable Pulling Analysis (Aker Kvaerner Subsea): Flexible umbilical cable pulled through J-tube

isoparametric quadrilateral 4-node, 9-node and 16-node ring elements. Linear 4-node and quadratic 10-node

tetrahedron element, trilinear 8-node Hexahedron element, and thin plate element were developed.
