We engineer energy and process facilities end to end: upstream and gas processing, refining and petrochemicals, hydrogen, storage and terminals, with the power, distribution and utilities that keep them running. New units, revamps and expansions, from FEED to start-up.
Energy projects combine licensed process technology, demanding operating conditions, strict international standards and complex logistics, and increasingly need to be delivered faster, in modules, with less site construction. Power, utilities and gas systems are too often engineered late, as isolated packages, after the process is fixed
We support clients in transforming process concepts into engineered, manufacturable and executable projects, across the whole value chain, with power, utilities and gas systems considered as part of the complete facility. Our methodology is aligned with internationally recognised standards and the requirements of major licensors, including projects incorporating Honeywell UOP process technologies
Six service lines, each delivered as a study, an engineering package or as part of a complete project
Process engineering for new units, capacity or yield upgrades and product-specification projects, integrated to licensor requirements
Treatment, conditioning and compression facilities from wellhead to export specification
Tank farms and logistics facilities designed for safe, efficient and expandable operation
Safe disposal of process upsets and recovery of gases that would otherwise be burned
Power and utility systems engineered with the process rather than added afterwards
Modifications on operating sites, where tie-ins, access and shutdown windows decide the schedule
A reference concept from our refining work, designed for 12,000 BPD of naphtha feed: two identical 6,000 BPD hydrotreating trains built as shop-fabricated modules, a common stripper, a catalytic reformer with three reactors in series, stabiliser and hydrogen management, and one set of shared utilities. Drag to rotate, tap a station to see its function and what CAC engineers there.

Design basis: 12,000 BPD total naphtha feed, split across two 6,000 BPD hydrotreating trains so that either train can be taken offline for catalyst change-out while the other keeps the reformer running at reduced charge. The reformer, stabiliser and shared utilities are sized on the combined 12,000 BPD of hydrotreated naphtha. Configuration follows publicly documented naphtha hydrotreating and catalytic reforming practice; it is a reference concept, not a licensor design, and uses no proprietary catalyst or process data.
A staged, gated approach that lets the client stop, adjust or proceed at each decision point
Scope, feedstock and product basis, capacity, site constraints and licensor requirements captured in a design basis and a Class 5 cost range
Concept and FEED, process design, simulation, PFDs, equipment list, plot plan and a Class 3 estimate for the investment decision
Detailed multidisciplinary design with a 3D model, P&IDs, isometrics, datasheets and specifications issued for procurement and fabrication
Vessels, skids and modules fabricated to code with inspection, followed by installation support, commissioning and performance testing
Every scope is staffed from the same multidisciplinary team, so process, mechanical, piping, electrical, civil and control engineers work from one model and one design basis.
Applicable codes are confirmed with the client and licensor at the start of every project
Representative scopes drawn from the work we take on
Two shop-fabricated hydrotreating trains with a common stripper and a catalytic reformer, designed as transportable modules to cut site construction time
Relief-load and flare-header review on an operating site with tighter emissions limits, followed by a recovery unit tied in during a planned shutdown
New storage tanks, loading bays and firewater system added to an existing terminal without interrupting operations

Ask an engineerYes. We integrate licensed technology to the licensor design basis and review requirements, and we manage the interface between the licensor package and the rest of the plant design. We do not replace licensor design or guarantees, and we do not claim licensor approval for concepts that have not been reviewed by them
Yes. Modularisation is considered from the concept stage, module limits, lifting and transport envelopes, structural frames and interfaces, so that equipment, piping, instrumentation and electrical can be integrated and tested in the factory before shipment
Yes. Brownfield work starts with a survey and an as-built verification, followed by a tie-in strategy that fits the available shutdown windows, so that most work can be prepared and prefabricated while the plant runs
A written report with the design basis, options compared on technical and cost criteria, an estimate with a stated accuracy class, a schedule and a recommended route, enough to take an investment decision or to start FEED
Pressure vessels, skids and modules are fabricated through our manufacturing partners under CAC-managed inspection and test plans, so the design office and the workshop work to the same drawings and acceptance criteria
