Precision engineering for complex industrial projects.
EPC-grade civil and structural design for Oil & Gas, Power, Petrochemical and Heavy Industrial facilities, delivered with accuracy, code compliance and constructability built in.
Engineering you can build on.
LINE CONSULTANTS™ is a specialist engineering consultancy focused on Civil & Structural Engineering for Oil & Gas, Power, Petrochemical and Heavy Industrial projects, with specialist depth in structural dynamics and machine foundations.
Founded by Ritwick Bhattacharya, a Civil & Structural Department Leader with 22 years of global EPC experience, we help EPC contractors, OEMs and project owners deliver structures that are right first time: accurate, compliant and practical to build. Established in 2026, we are an MSME (Udyam) registered consultancy based in Kolkata, with a presence in Baroda.
Where every turbulence gets damped
In structural dynamics, damping is what brings a vibrating system back to rest. It's how we see our role on a project: absorbing technical uncertainty, schedule pressure and interface risk so your structures, and your project, stay stable.
Precision
Rigorous static and dynamic analysis, with checked deliverables that hold up to client and third-party review.
Compliance
Design to API, BS, ACI, ASCE, IS and Eurocodes, plus your project specifications.
Constructability
Practical designs that fabricators and site teams can build efficiently.
Risk-Managed Delivery
Early interface and clash management, clear documentation and dependable schedules.
Understand
Scope, site data, codes and specifications reviewed up front.
Engineer
Analysis, design and documentation using industry-standard tools.
Verify
Independent checks, 3D model review and multi-discipline coordination.
Support
Vendor reviews, technical queries and support through construction.
End-to-end civil & structural engineering.
Delivered to international codes and your project specifications, from proposal through to construction support.
Civil & Structural Engineering
Complete scope for process plants, utilities and industrial facilities, including plot development, buildings and underground works.
Steel & RCC Structure Design
Pipe racks, technological structures, shelters, platforms and equipment supports, with connection design and MTOs.
Foundation Engineering
Shallow and pile foundations for structures, tanks and equipment, plus dynamic machine foundations.
Modular & Stick-Built Structures
Module design covering in-place, lifting, load-out, SPMT, sea and rail transportation cases.
Proposal Engineering
BOQs, RFQ packages and technical queries that help EPC contractors bid accurately and competitively.
FEED & Detailed Design
Design basis through issued-for-construction calculations, drawings and specifications.
Vendor Drawing & 3D Model Review
Structured review of vendor documents and 3D models to catch errors and clashes before fabrication.
EPC Multi-Discipline Coordination
Interface management with piping, mechanical, electrical and instrumentation teams.
Structural dynamics & machine foundations.
Vibrating machinery, blast loads, earthquakes and wind can all drive a structure toward resonance. We keep foundations and support structures within amplitude and stress limits, protecting equipment, people and production.
Machine Foundation Dynamics
Block, table-top and spring-mounted foundations for rotating and reciprocating machinery, with modal checks and resonance mitigation.
Soil–Structure Interaction
Dynamic SSI using frequency-dependent impedance functions, and simplified Richart and Barkan spring methods.
Blast & Seismic Analysis
Transient blast analysis of process structures, control rooms and shelters; response spectrum and time history analysis.
Wind-Induced Vibration
Aerodynamic response and dynamic bracing optimisation for ACHEs and large air-cooled condensers.
Vibration Isolation & Rerating
Isolation tuning for heavy vibrating equipment, and compressor foundation rerating for higher loads and speed changes.
Category IV Vibration
Structural & Machinery Vibration training to Vibration Institute standards, backed by two decades of dynamic design on live EPC projects.
Where structural accuracy matters most.
Heavy loads, dynamic equipment, harsh environments and demanding schedules.
Oil & Gas
Upstream, midstream and downstream facilities.
Power Generation
Thermal, cogeneration and balance-of-plant.
Petrochemical
Process units, refineries and complexes.
Heavy Industrial
Steel, mining and mineral processing plants.
EPC Contractors
Discipline delivery and peak-workload support that fits into your project systems.
OEMs & Equipment Manufacturers
Supports, skids and foundations for ACCs, HRSGs, furnaces, filters and more.
Modular Fabricators
Module structures with SPMT, sea and rail transportation analysis.
Proven on landmark projects worldwide.
Civil and structural engineering across the Middle East, Africa, Central Asia, Australia, North America and India.
