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.

Impact #1	The use of ProteusDS has resulted in significant operational benefits. For mooring analysis, it has enabled accurate resolution of slack line and snap load events, and time-domain analysis of mooring arrangements taking into account the effects of the wind, current, and wave loading. For ROV pilot training, it has reduced the risk of operation by allowing the project team to test their plans before anything goes in the ocean. For tidal energy platforms, it has allowed for extremely quick iteration for designs/optimization and reduced risk for full-scale deployment. Lastly, for cable lay operations, it has enabled the generation of alternative deployment plans based on simulation data.

Benefit #1	ProteusDS allows users to simulate hundreds of scenarios in a shortened time period, saving time and money.
Benefit #2	Longer elements for a given mooring line can lead to substantial increases in simulation execution speed due to larger allowable numerical time steps and fewer calculations per line.
Benefit #3	The ProteusDS + VROV partnership is a cost-effective opportunity for subsea trainees to gain operational familiarity while greatly reducing the risk to personnel and active ROV equipment.
