PTQ Q4 2022 Issue

The concrete wall size should be adequate to accom- modate the vessel motions. The saddle base plate should be aligned with the wall centroid to avoid load eccentrici- ties. Shear stress along the junction line with the pile-cap is critical and must be assessed. Magnification factors must be applied to the vessel diameters for wind analysis to account for attached pipes, platforms, and ladders. The magnitude shall be established based on vessel diameter. Effective width can be used by the engineer to simplify the concrete design. An integrated saddle support (INTS) system is very eco - nomical to use if the vessel is surrounded by steel platforms. However, the engineer must account for load interaction. Vessel bundle pull forces (BP) are significant and, in some cases, may control the design. The magnitude of BP is estimated by vessel vendors. This load category should be combined with wind or seismic loadings.
