PPV Engineering is a consulting and design office specializing in design and analysis of pressure vessels, piping, and steel structures for the oil & gas, food, and chemical industries. The company also provides services for mechanical engineering and project and construction management.
For this project, PPV Engineering was contracted by a company in the food industry to fit new product storage tanks into an existing butter-making facility, located in the Netherlands.
Originally, the customer was struggling with how to deal with its leftover product from the facility, as disposing this as waste would have been costly and inefficient. If stored in a hygienic manner, the leftover product from the butter factory could be mixed with other food stuffs to create a new product, enabling significant cost savings. The goal of the project was to be able to reuse surplus product and find a hygienic way for storing both the leftover and new product created from it.
Key challenges included the limited space of the existing facility and the difficulty of determining whether the new tanks would fit. As the existing space was limited, PPV Engineering first investigated the possibility to place the new storage tanks partly outside the facility, through the roof. After careful investigation, it was revealed that the food hygiene standards would not permit the surplus product to be stored outside the factory building.
After this became clear, PPV Engineering researched alternative methods to overcome the limited space, and eventually it was decided to raise the roof of the facility by five meters to create additional space.
First, PPV Engineering and its customer jointly defined and agreed on the scope of the project. Next, the companies executed research to determine the design of the process, the changes that would need to be made to the building structure, and to determine the capacities of the various storage tanks that would need to be installed to support the new food production process.
Once the business plan was in place and approved by both parties, PPV Engineering started basic engineering for the project. During the process study, PPV Engineering and the customer agreed that five new tanks were to be fitted into the existing facility consisting of: a product tank with capacity of 30 tons to hold the new product, two raw product tanks each 20 tons, a mixed product tank of 25 tons, and an additives tank of three tons.
Having used the software for several years on a variety of other small projects, Intergraph® CADWorx® Plant Professional was used for the basic engineering. The first step was to survey the existing facility to determine space available for the new tanks. The customer did not have existing detailed drawings of the plant available. PPV Engineering was informed by their customer that the maximum space available for the new tank installation was approximately 75 m2 in total.
Next, a preliminary design for the installation was created. After approving the installation plan, the customer entered into a bid process to identify an equipment and piping contractor. These offers were used to create an estimate for the budget to be allocated to the project.
Intergraph CADWorx Plant Professional was chosen for the project for several reasons:
- User friendliness and ease of use enabling faster project execution
- The efficiency and automation provided by the complimentary CADWorx P&ID module
- Integration with CAESAR II for pipe stress analysis
Willem Bazuin, owner of PPV Engineering commented: “CADWorx Plant Professional is an open program and enables easy customization where needed. Especially when it comes to modifications, the software enables tremendous time savings. This is the case particularly when implementing the CADWorx P&ID module and using it together with the plant design.”
