Introduction In the process of extending an existing power plant, the addition of a new power plant was deemed necessary. This new facility was designed around a Combined Cycle Unit (CCU), which integrated both a Gas Turbine and a Steam System. Notably, the surface condenser of this new plant was
Hydrogen generation equipment has an inherent risk for internal explosions, posing an issue to safety. The hydrogen piping and equipment are required to withstand internal explosions by limiting the damage to deformation. Although this disqualifies the component for future use, safety is not compromised. The objective was to find a
A District Cooling System (DCS) fits the sustainability challenges that our society is challenged with. It provides cooling capacity from a central facility; chilled water is distributed from this central facility to multiple buildings through a network of underground pipelines. The central cooling facility works more power efficient and it
Shell is building a biofuels facility at the Shell Energy and Chemicals Park Rotterdam, the Netherlands (Pernis Refinery) that will have an annual production capacity of 820,000 tonnes of biofuel.

Why Pay Attention to a Line Filling Process? During a start-up/line filling process a wave front of fluid progresses it’s way through the empty* parts of the line. However, when this front is required to change direction through bends the change in momentum generates an unbalanced force, this unbalanced force
What is Hogging and Sagging and what are the effects on piping? When waves pass over the length of a ship, the ships profile rises and bows following the peaks and troughs of said wave due to the changes in bouyancy along the length. This effect is known as hogging
