Design & Engineering Services

Aattrl provides design engineering solutions to Mechanical, Piping, Process, electrical, Instrumentation, Fire & safety, Civil & structural engineering disciplines; as well as advanced specialties such as simulation, enterprise integration, integrated automation processes and interactive 3D and 4D modelling to Oil & Gas, Petrochemical and manufacturing industries in Saudi Arabia, UAE, Qatar, Oman, Kuwait, India and Other countries.

We review the scope and analyse the technical specifications of the project and provide a report which is technical, economic, legal and schedule feasible, with regard to the changing trends and currently active specifications in the industry. It progresses through distinct activities through multiple engineering and project management disciplines. This report helps to ascertain the probability of successful completion of the project and acts as a primary basis for Front End Engineering Design (FEED). 

Our services also include rendering assistance for procurement of orders, through bidding assistance, review of RFQ/RFP documents of client and its details. Study, analyze and suggesting technical requirements for submission of the Bid Document. Strategize the cost, BOQ with identification of sources of materials and Estimation of the projects with most value Engineering. Assist to client at all stages in the bidding to facilitate appropriate data/information submission, providing assistance/Technical support during the contract finalization. 

We transform the conceptual/feasibility study of the project into comprehensive engineering design, to client’s requirements and in compliance to statutory regulations. The FEED focuses the technical requirements as well as rough investment cost for the project. Our FEED procedure includes

• Validating basic engineering
• Piping & Instrumentation Diagrams and Process Flow Diagrams
• Heat Exchangers preliminary thermal design
• Flare load and utility summaries
• Static and Rotating equipment datasheets
• General arrangement followed by Detailed Plot Plan
• Instrumentation & Safety devices datasheets
• Preliminary sizing of cables, transformers, DC system, motor control schematics, diesel generators, bus duct, earthing conductors, UPS, etc.
• Preparation of load schedule, lighting schedule, earthing schedule etc.
• Control & Shutdown Philosophy, Operation & Maintenance Philosophy, Fire & Gas Philosophy, etc.
• Classification of Hazardous Area, layout drawing of equipment, etc.
• Illumination engineering
• Ergonomics survey Estimation of indoor and outdoor Light fixtures
• Civil & Structural Layouts Quantity Surveying
• Constructability reports

We provide services that includes planning, designing, costing, estimating, etc of a project. It also includes feasibility or viability studies of the project. 

We assist in the preparation of bids by providing Material Requisitions along with Data Sheets and Specifications for major items in Mechanical, Piping, Electrical and Instrumentation disciplines, and preliminary MTO's for bulk items and Structural steel.

Considering the client’s budget and time constraints, we work within these parameters to achieve the highest quality design possible. Our team of experienced engineers has the ability to envision various cost-effective concepts that won’t compromise quality and client requirements.

This phase of engineering involves all required disciplines of engineering to come together to give their respective deliverables and progress the project towards reality. Now the ideas change into entities.

Detail engineering is the key for any project to be successful in terms of end-user delight and functionality. The following components will be the deliverables based on the nature of the project.

• Design basis report and / or design criteria
• System and component sizing calculation
• Technical Specifications for packages and components
• Technical bid evaluation reports
• Vendor drawing review.
• Layout and Physical design including
• Plot Plan
• Site Grading and levelling
• Plant and building general arrangements.
• Civil & Structural foundation and superstructure design
• Equipment Layouts
• Hazardous area Layout
• Pipe support engineering including pipe stress analysis.
• Piping layouts including isometrics and/or piping composites.
• 3D-Modelling of Equipment, civil, structural and piping
• Electrical & Instrumentation Cable schedule and interconnection /Logic diagrams
• Power System Studies
• Pre-commissioning and Commissioning activities
• Reliability run and Performance Guarantee tests
• As-built drawings
