Sanjeev Chandriki

Senior Design Engineer

B Tech (Mech)


In his career to-date, Sanjeev has had the opportunity to work for a number of multinational companies and develop his passion for engineering. He prides himself on asking the right questions at the right time and being an inclusive team member. Sanjeev takes a holistic product life cycle approach to his work. His over arching involvement in many large projects, project management experience, and desire to solve problems make him a very effective engineer. He enjoys working as part of a team and is a natural leader.

I am a qualified mechanical engineer with wide experience in heavy industry, pressure vessels, turbomachinery, food processing equipment etc. I am a motivated engineer who likes to see the concepts grow to reliable working equipment. I believe the success of any project lies in good working relationship among the team and thus flex my style to suit different customers. I constantly look for product / process improvement opportunities and capture best practices where possible.

I developed strong skills in using various CAD tools for both design and analysis. I have worked with ASME, AS, NZS codes to meet regulatory requirements. I performed various structural, thermal & product life evaluation analysis. I visualize the product through its life cycle to capture features for manufacturing, transportation and ease of use, thus creating a lasting product.

Project Experience

Dewatering Roller Analysis


Linear Sample Divider

Working through the concepts, previous designs, and project requirements, Sanjeev developed a new piece of aggregate sampling equipment (LSD). He sized the structure and actuators for various motions in the machine, and worked with suppliers to find suitable hardware.


Dewatering Roller Analysis


Dewatering Roller Analysis

Validated a roller repair solution being presented to their customer. Performed an FEA to compare the design of the repaired roller to that of original design. Sized bolts for fatigue loads & optimized shrink fit dimensions. CASE STUDY


Pressure Vessel Design

Based on the concept sketches from process engineer, sized the pressure vessels. Performed calculations for design to meet ASME pressure vessel code requirements. Developed 3D models and manufacturing drawings. Got the design certified for PS1.


New Production Line Setup

Provided engineering support, project engineering for setting up a new production line at Sanitarium. Working with their team, developed layout concepts as to minimize operator fatigue and optimize production time. Designed some of the conveying equipment. Coordinated with suppliers & fabricators to setup the various elements of the production line.

General Electric, Steam & Gas Turbine Components


Steam & Gas Turbine Components

Developed a new inlet design for a super critical steam turbine, resulting in US$1.5M savings. Also developed a new concept for cooling turbine horizontal joint bolts (US Patent 20150159512). Process improvement initiatives led by Sanjeev helped reduce engineering time of his team by approximately 20%.


Powder Handling System

Worked closely with Fresco team to complete the detailed design for powder debagging & transfer system of a dairy plant. The project involved equipment like silos, support platforms, conveyor, debagging equipment, piping etc. Reviewed design for ATEX requirements & performed HAZOP analysis. Generated manufacturing drawings, Installation manuals and product documentation.



Conveyor System Design

Supported Stackflo’s engineering team to complete detail design of a large milk crate conveyor system. Developed new bend sections & transitions. Adapting to their system requirements generated drawings and BOM.

Service Engineers


Door Lift Mechanism

Based on the concept provided by customer, performed detailed design of a hydraulic lifting mechanism, to lift a heavy door of ~5 tons. Performed calculations and sized various elements of mechanism viz. rope, sheaves, bearings, cylinder, structure etc. Developed 3D models and manufacturing drawings.

Heavy Equipment & Pressure Vessels


Heavy Equipment & Pressure Vessels

Involved with projects for Exxon Mobil, Chevron, KBR, Fluor Daniel, and Bechtel. Developed thorough understanding of thermal design, ASME codes, and design for high temperatures.
