Detailed Engineering Solutions

Our multi discipline team carries your project from concept through commissioning, bringing process, mechanical, electrical and instrumentation engineering together under one roof so that the design that reaches your site is coherent, buildable and ready to operate safely.

Strategic context

Why detailed engineering solutions matters

Detailed Engineering Solutions converts process design intent into construction ready specifications. Our team delivers the full multi discipline scope across process, mechanical, electrical and instrumentation, from FEED through PFD and P&ID issue, equipment sizing and specification, simulation and heat and mass balance, pressure vessel and exchanger engineering, instrumentation and PLC and DCS architecture, cause and effect matrices, electrical load and earthing and on through commissioning and the pre startup safety review. Every deliverable is traceable to the design basis and to the codes, standards and statutory rules that govern your jurisdiction.

Detailed Engineering Solutions
Engagement model

How we deliver

A phased, evidence led delivery model that runs from discovery through close out and is built around your facility, regulatory context, and lifecycle stage.

Concept and FEED
We establish the basis of design, select the technology, integrate inherent safety and prepare the heat and mass balance and preliminary PFDs and P&IDs that anchor every downstream phase.
Detailed Engineering
We deliver the multi discipline scope across PFDs, P&IDs and equipment datasheets, pressure vessel design per ASME and IBR, instrumentation per ISA 5.1 and electrical per IEC and IS 3043.
Procurement Support
We evaluate technical bids, review vendor documents, prepare material requisitions, witness factory acceptance tests and manage deviation MOC without scope leak.
Construction Support
We handle site engineering queries, deviation MOC, punchlist review, vendor coordination and pre commissioning support.
Commissioning and PSSR
We run functional testing and performance demonstration, conduct the pre startup safety review per OSHA PSM clause (h) and hand over documentation your facility can operate from.

Frequently asked questions

What do your detailed engineering solutions cover?

Our multi discipline team carries your project from concept through commissioning, bringing process, mechanical, electrical and instrumentation engineering together under one roof. The scope spans PFDs and P&IDs, heat and mass balance, equipment sizing and specification, process simulation, pressure vessel and exchanger engineering, instrumentation and PLC and DCS architecture, cause and effect matrices, electrical load and earthing, and commissioning support so the design that reaches your site is coherent, buildable and ready to operate safely.

Which codes and standards do you engineer to?

We engineer storage tanks to API 650, 620 and 2000, pressure vessels and piping to ASME BPVC Section VIII and B31.3 and B31.12, heat exchangers to TEMA and IS 4503, instrumentation and PLC to ISA 5.1 and IEC 61131, and electrical and earthing to IEC 60364, IEEE 80 and IS 3043. For India we also apply IBR 1950 and the CEA Regulations 2010. Every deliverable is traceable to the design basis and the statutory rules that govern your jurisdiction.

When should detailed engineering start?

It follows the FEED and design basis and runs through to commissioning. Engaging a single multi discipline team from concept avoids the FEED to detail rework loop that occurs when disciplines are contracted separately, and it lets inherent safer design be integrated from the earliest stage rather than bolted on once the P&IDs have issued.

What deliverables do you hand over?

You receive construction ready deliverables that avoid the FEED to detail rework loop, code defensible pressure vessel and heat exchanger packages, procurement specifications that hold up under vendor deviation review, an instrumentation architecture aligned to your SIL and cyber requirements, and a pre startup safety review evidence pack that closes the OSHA PSM mechanical integrity and readiness requirements.

Which sectors do you deliver for?

We deliver for refineries and petrochemicals, specialty and bulk chemicals, LNG, cryogenic and hydrogen, pharma and API manufacturing, power generation and hydrogen, and fertilizer and agrochemicals. The team is fluent across API, ASME, IEC, IBR and BIS in one engagement and manages the vendor and EPC interface without scope leak.
