Rally Engineering Inc. (Rally) was requested to complete the design of manways for entering vessels. This design would include detailed engineering calculations and general arrangement drawings. In addition, a capital cost estimate was produced to support the planning and approval for the work.
Originally, client was requesting to enter the vessels through the piping. However, Rally determined this was not feasible and a more cost-effective way was to add manways to each vessel. To complicate this design further, the vessels have over 12” of refractory. Rally designed the nozzle and hydrotest in such a way that the inside of the vessel did not need to be wetted.
Prior to project commencement, Rally completed a preliminary assessment on installing the manways on the vessels. Rally mechanical completed the nozzle design calculations, code and standards review, and ABSA submittal requirements.
