Engineering Design and Calculation Process:
Kick-Off & Technical Alignment
- Conduct kick-off meetings to validate project scope, define multidisciplinary roles, and establish milestones.
- Facilitate workshops with clients to align technical goals, site constraints, and critical deliverables.
Data Gathering, Onsite Validation & Risk Analysis
- Perform site surveys, collect existing drawings, P&ID, performance history, and physical constraints.
- Validate process data, conduct reliability assessments, failure mode analyses, and preliminary risk reviews.
Conceptual Engineering & Pre-Design Study
- Formulate multiple solution alternatives (conceptual designs) based on client needs and field realities.
- Perform risk analyses, rapid cost estimations (CAPEX/OPEX), and pre-design simulations (quick sizing, accessibility analysis).
Iterative Detailed Engineering
- Integrate design iterations across disciplines using FEA/CFD simulations for structure and processes, load flow and fault analysis for electrical systems, 3D drafting, and instrumentation/control integration.
- Conduct multidisciplinary peer reviews, regular design review meetings, and update designs per client feedback.
Technical Documentation & Approval
- Prepare comprehensive technical documentation including shop/fabrication drawings, technical/material specifications, commissioning manuals, and Bills of Materials.
- Present engineering deliverables, engage stakeholders (operations, HSE, procurement), and revise per external audit or third-party comments.
Tendering & Procurement Support
- Assist in tender specification preparation, vendor evaluation, and technical clarifications with suppliers/subcontractors.
- Conduct quality control visits to workshops/vendors as needed to validate the supply chain.
Fabrication, Field Supervision & Agile Revisions
- Co-design and co-monitor fabrication processes including inline inspection, NDT, welding supervision, and Factory Acceptance Testing (FAT).
- Supervise erection/installation: checking alignment, managing field modifications, updating as-built documentation.
- Apply agile engineering to accommodate scope changes or site findings swiftly.
Commissioning, Handover & Optimization
- Oversee commissioning, functional testing, parameter tuning, and real-time performance audits.
- Conduct operator training, prepare as-built documentation, Manufacturing Data Reports (MDR), and hand over compliance documents.
- Review lessons learned and provide technical support for post-operational improvements.
