CADWorx & Analysis Solutions

Code Tech International is an Indian EPC services company operating in industrial settings since 2009. The company chose Hexagon solutions for executing different design projects in a challenging offshore environment, and this blog post features one of the two real-life project examples: a seawater filtration unit design on a fixed offshore platform skid.

The Goal

Both projects’ key goals were to guarantee timely delivery of the designs while keeping the costs down for both Code Tech International and their clients.

The Challenge

The project involved designing a seawater filtration unit for a conventional water treatment plant consisting of structural design and frontal piping. This involved the piping in front of the vessel area that was accessible only from the front side of the unit. The water treatment plant was located on a fixed offshore platform skid.

Once underway, the project stayed on schedule, and the plant design deliverables were produced quickly. Initially, the designs were accepted by the intermediate client, the engineering company. However, during the next review phase, the layout of the plant was rejected by their client, the owner/operator. This was due to lacking adherence to their specifications. The design had to be revised and all the piping re-routed to ensure compliance and safety.

Another challenge was how to lift the finished multi-tier skid in its assembled condition due to its overall volume and dimensional extents (4,3 meters wide x 9,5 meters long x 6,4 meters high, weighing 75 metric tons).

The Solution

After receiving feedback from the owner operator regarding the specifications, changes to the design could be quickly resolved due to the robust design modification features of Hexagon’s CADWorx Plant Professional. This made re-modeling or editing existing routes quick and easy. The re-analysis of specific lines was equally fast due to the bi-directional integration between CADWorx and CAESAR II.

The second challenge, estimating lifting procedures for the finished skid, was also easily solved with Hexagon solutions. Due to the flexible 3D modeling capability of the CADWorx software, multiple options of lifting procedures were prepared for a client review in a limited time frame. This also helped Code Tech International reduce the time needed to finalize the options for critical lifting.

The company chose Hexagon’s CADWorx Plant Professional and PV Elite for the project to ensure timely and economical project delivery. At the beginning of the project, the estimated time for the design work was calculated at 45 days using Hexagon solutions, compared to 65 days when using other software – a 30% decrease!

Moving Forward

This was one of the first offshore projects Code Tech International executed with CADWorx, and the company was impressed with the software. Mozammil Khan, the company owner and proprietor of Code Tech International, said, “One of the greatest advantages of using Hexagon’s solutions was the simplicity and flexibility of the software. This allowed us to train our employees quickly, enabling us to allocate resources to the projects based on their status and urgency.”
