TopEngineer developed steel detailing (shop and erection drawings) for the needs of liquefied natural gas (LNG) plants. Documentation was developed for Technip company. The uniqueness of this project for our company was as follows: 1. As initial data, we were provided with a rod model with calculated sections and forces for joints. We, in turn, made the calculation of all connection for metal structures. 2.The design often changed in the project due to updated tasks from technologists. We tracked changes and adjusted drawings for steel fabricators or site workers.
