This example shows the main take-off line for tanker loading from a LNG storage tank facility.
FluidFlow3 solves continuity, momentum and energy equations iteratively to arrive at an accurate solution. Phase states and physical properties are calculated at each point in the network. Solutions are valid for all flow regimes.
FluidFlow3 was used to design and model the liquid and vapor lines, including compressor plant, in this system.
This fire hydrant system was designed and developed using FluidFlow. The system includes 42 hydrants, diesel and electric (duty and standby) pump sets, tees, bends and a total pipe length of 3256 M. When analysing this system, consideration was also given to the resistance downstream of the hydrant, i.e., the resistance from the connected 100 ft 2.5 inch fire hose and the resistance posed by the required discharge nozzle. Modeling this system allowed the customer to develop a detailed insight into the operating performance of the plant and also quickly identify any pipe velocities which exceeded the design value of 20 ft/s as set out in the NFPA Guide.
Using FluidFlow, our customer quickly established the plant performance, optimised the system to eliminate undesirable operating conditions whilst ensuring the system complied with the requirements of the design brief and NFPA guidelines. The pump operating speeds were also optimised to ensure the required flow rate was maintained for various hydrants in operation whilst minimizing the system energy requirement.
FluidFlow accelerated the design and delivery of this project for our customer with the added benefit of creatign an efficient system design.
The swivel system employed in FPSOs provides a flexible coupling with the crude oil suppy pipeline, allowing the vessels to rotate as required by the weather and sea conditions. It is crucial for the engineers to understand the friction characteristics of the swivel, and how the oil flowrate can be affected as the ship revolves around the coupling.
Using FluidFlow3 in conjunction with site data for existing FPSOs, our customers have established a benchmark for modelling the swivel that can be applied to future designs. As FluidFlow3 is a modular program, our customers have been able to model non-Newtonian flow and friction losses within the same environment, the results of which have been correlated to site data at different swivel rotations. This particular model included annular pipe friction loss methodologies.
