Start-up meeting, project review and proposed solution

To deliver the optimal solution, it is important to go through in detail various factors that affect product choice, type of solution, investment objective, and other requirements at an early stage of the project.

Start-up meeting

A start-up meeting is important to find out about a variety of factors that can affect the choice of equipment and solution to achieve the most efficient and sustainable result. At this stage, current regulatory requirements are also discussed.

We pefer to do the start-up meeting as a site visit or web meeting, depending on your preference.

Project review

During the start-up meeting, we review existing documentation and tank data (tank cards, measurements, etc.). Sometimes it is necessary to supplement the information with, for example, a roundness and rim space measurement to optimise the solution and minimise emissions.

Examples of other important factors to discuss and take into account include:

  • Type of product stored today and in the future
  • Tank construction - surface area, open or closed tank, type of floating roof, etc.
  • Desired efficiency
  • Regulatory requirements
  • Impact of external factors such as rain, snow and wind
  • Timeframe for emptying the tank, any repair work on the existing tank, delivery and installation
  • Investment objective

Summary and proposed solution

Using the information discussed during the site visit, we prepare a summary that we review with the client to ensure that we agree on the scope of the project.

The next step is that we put together and present a proposal for a sustainable and efficient solution, focusing on reducing emissions, maximising tank utilisation, achieving the highest possible safety rating and ensuring a long operating life.
