About The Customer
The customers in this case study are diverse, ranging from marine engineers designing mooring systems, ROV pilots in training, engineers assessing the dynamics of floating tidal energy platforms, to those involved in cable lay operations. These customers operate in complex and challenging marine environments where they need to consider various factors such as line types, environmental loading effects, and the large number of possible layouts. They require sophisticated tools and software to simulate and predict various scenarios to optimize their operations and reduce risks.
The Challenge
The case study presents four distinct challenges faced by different sectors of the marine industry. The first challenge was to design mooring systems, considering the tension in the mooring lines, the movement of the floater, anchor capacity, and interactions of lines with the seabed. The second challenge was to equip ROV pilots training with simulation software and real-time data about structure, cable, and umbilical tensions. The third challenge was to efficiently assess the motion/response of tidal energy platforms in complex wind, wave, current, and loading, and ensure the design is maintainable. The last challenge was to determine the effect of strong tidal currents acting on cable and barge during cable lay operations and determine the operational impacts of having to lay cable after a slack tide.
The Solution
ProteusDS, a dynamic analysis software by DSA, was used to address these challenges. For the mooring analysis, ProteusDS features a cubic-spline lumped mass cable model that is used for modeling mooring lines. The model can be used to simulate a variety of flexible structures. The ProteusDS hydrodynamic modeling capabilities are designed to assess wave, current, and wind loading on floating structures which are coupled with a mooring system. For the ROV pilots training, ProteusDS was integrated with GRI’s VROV to create a 3D interactive real-time simulation software. For the tidal energy platforms, a numerical model was developed to predict the platform motion and loading. Lastly, for the cable lay operations, a numerical model in ProteusDS was developed to simulate the effects of current, wind, and waves on the barge and cable.

Smart Water Filtration Systems
Before working with Ayla Networks, Ozner was already using cloud connectivity to identify and solve water-filtration system malfunctions as well as to monitor filter cartridges for replacements.But, in June 2015, Ozner executives talked with Ayla about how the company might further improve its water systems with IoT technology. They liked what they heard from Ayla, but the executives needed to be sure that Ayla’s Agile IoT Platform provided the security and reliability Ozner required.

Vestas: Turning Climate into Capital with Big Data
Making wind a reliable source of energy depends greatly on the placement of the wind turbines used to produce electricity. Turbulence is a significant factor as it strains turbine components, making them more likely to fail. Vestas wanted to pinpoint the optimal location for wind turbines to maximize power generation and reduce energy costs.

Predictive Maintenance for Industrial Chillers
For global leaders in the industrial chiller manufacturing, reliability of the entire production process is of the utmost importance. Chillers are refrigeration systems that produce ice water to provide cooling for a process or industrial application. One of those leaders sought a way to respond to asset performance issues, even before they occur. The intelligence to guarantee maximum reliability of cooling devices is embedded (pre-alarming). A pre-alarming phase means that the cooling device still works, but symptoms may appear, telling manufacturers that a failure is likely to occur in the near future. Chillers who are not internet connected at that moment, provide little insight in this pre-alarming phase.
