What We Do

Five capabilities, one delivery team.

From concept design through site supervision and independent advisory — a single accountable engineering partner across the asset lifecycle.

  • Engineering

    Multidisciplinary engineering across naval architecture, structural, and pipeline disciplines — from concept through detailed design and class approval.

  • Surveys

    Technical scope preparation, data review, and structural interpretation for geophysical, geotechnical, and inspection surveys across marine and offshore assets.

  • Site Supervision

    On-site engineering oversight during fabrication, installation, and commissioning — ensuring quality, safety, and compliance at every stage of construction.

  • Project Management

    End-to-end project delivery — scope, schedule, cost, QA/QC, and vendor coordination — acting as Owner's Engineer from FEED through to installation and handover.

  • Advisory

    Independent technical advisory for operators, EPCs, and investors — covering feasibility studies, bid evaluation, risk assessment, and regulatory compliance strategy.

Frequently Asked Questions

Answers for owners, EPCs & shipyards.

The questions we hear most from operators, contractors and port authorities evaluating an engineering partner.

What engineering services does Kannamwar Engineering provide?

We are a multidisciplinary offshore, marine and pipeline engineering consultancy. Our services span concept and FEED studies, detailed engineering, 3D modeling, construction and installation engineering support, site supervision, and independent owner’s engineering across the full asset lifecycle.

Which classification societies and codes do you design to?

Our deliverables are aligned with ABS, DNV, Lloyd’s Register (LR), Bureau Veritas (BV) and IRS class requirements, and with international codes and standards including IMO, ASME, API, DNV-ST-F101 and PD 8010 — validated through third-party inspection (TPI) where required.

Do you handle FEED and detailed engineering for offshore oil & gas projects?

Yes. We take offshore platforms, subsea pipelines, FPSO/FLNG facilities and marine terminals from front-end engineering design (FEED) through detailed engineering, class approval drawings and as-built documentation.

What design software and analysis tools do you use?

SP3D, AVEVA E3D and AutoCAD (including Plant 3D and Civil 3D) for design and modeling; SACS, STAAD.Pro, ANSYS and Abaqus for structural analysis; Maxsurf, GHS, MOSES and OrcaFlex for naval architecture and hydrodynamics; CAESAR II and PIPESIM for piping stress and flow assurance.

Can you support vessel conversions such as OSV to WSV or FPSO projects?

Yes — vessel conversions are a core capability, including OSV-to-WSV (well stimulation vessel) conversions, FPSO/FLNG hull and topsides engineering, stability and mooring analysis, and class approval management.

Where is Kannamwar Engineering located, and do you work internationally?

We are headquartered in Mumbai, India, and deliver projects worldwide for operators, EPC contractors, shipyards and port authorities across offshore oil & gas, LNG, marine infrastructure and coastal engineering.

Do you provide third-party review and owner’s engineering services?

Yes. We act as independent owner’s engineer and third-party reviewer — verifying designs, reviewing contractor deliverables, and providing technical advisory through construction, installation and commissioning.

How do we start a project with you?
