Aircraft Landing Fittings

ABZ assisted a manufacturer of aircraft landing fittings with assessing the hydraulic design of a new hydraulic operator. The company had a prototype under development and needed to establish a test program. The scope of the test program needed to be comprehensive enough to establish the operator's reliability but at the same time not unnecessarily impact the production schedule. ABZ provided a model of the fittings using the Branch version which in turn established the testing parameter for the operator.

LNG Tanker

ABZ assisted in modeling the entire cargo section for a liquified natural gas (LGN) vessel. This was required to in order to determine the ability of the vessel to discharge cargo, under specific constraints, at terminals other than those for which the vessel was originally intended for trade. The analysis showed that the several pumps would have to be replaced in order to meet the discharged requirements at the anticipated trading terminals.

Angel of the Winds Casino

ABZ performed an independent analysis of the chilled water system for the new data centers being constructed at the Angel of the Winds Casino in Arlington, WA. The system was comprised of a chiller, air conditioning units, and piping to transfer the chilled water. Using Design Flow Solutions, ABZ modeled an accurate representation of the flow rates and pressure drops throughout the chilled water system, and verified that the system design for the chilled water system met the specifications set forth for proper operation. ABZ analyzed five different scenarios for the chilled water system. These five scenarios included both an ideal model and a conservative model, as well as several possible line-ups or system states.

Monticello Control Rod Drive System

In support of the Monticello Nuclear Generating Plant power uprate project, ABZ analyzed the Control Rod Drive Hydraulic (CRDH) system. The CRDH system is complex set of pumps pipes and valves that provide motive force for the control rods but can also be used to provide cooling water during emergencies. Using Design Flow Solutions (DFS) software, ABZ modeled system flow rates to the reactor vessel to ensure proper operation under all operating conditions. The CRDH system DFS model replicated normal operating condition of the CRDH system, as well as various alternate conditions, by manipulating variables and system configurations. The output of the model provides documentation supporting analysis for different makeup flow rates to the vessel for various CRD system configurations. These flow rates were used to in accident code calculations for the 2010 Extended Power Uprate (EPU).
