McLaren Speaking at ASBPA 2021 National Coastal Conference

McLaren Speaking at ASBPA 2021 National Coastal Conference

Geaux Resilient! On Thursday, September 30th and Friday, October 1st, members of McLaren’s Marine Engineering team are speaking at the ASBPA (American Shore & Beach Preservation Association) 2021 National Coastal Conference in New Orleans, Louisiana.

Advocating for Healthy Coastlines, ASBPA is dedicated to preserving, protecting and enhancing our coasts by merging science and public policy, and this years’ conference “Geaux (french word-play on the verb go) Resilient” will focus on coastal science, policy, and technology.

Leaders in coastal engineering and resiliency, our marine experts are sharing their knowledge on topics that are changing the landscape of the maritime industry.

Meet McLaren’s Speakers

Coastal Engineering Analysis and Small Craft Harbor Design Optimization

Thursday, September 30th, 4:10-4:30 pm CDT

The intent and purpose of this project is to provide engineering design support to upgrade and increase the resiliency of the a District Pier used for berthing vessels and small craft harbor. Structures proposed to protect the small craft harbor will consist of pile anchored floating docks and vertical wave screens.

To support the structure design, a comprehensive coastal engineering analysis is required to determine the local service conditions and extreme storm conditions such as 100-yr return period storm and their impacts on the proposed structures and moored vessels. The coastal engineering analysis includes winds, tidal currents, wind waves, vessel wakes analyses based upon historical data and engineering calculations. A wave model (BOUSS-2D) has been developed for the riverine project area to simulate the propagation and transformation of waves and wave interaction with structures. The results are used to inform layout plan alternatives to optimize the best alternative layout under the different wave scenarios. Environmental loading on the structures shall be developed from the coastal engineering analysis and modeling and for use in the subsequent design phases.

Advances in Assessing and Managing Waterfront Infrastructure with Remote Sensing Inspection Techniques

Friday, October 1, 10:20-10:40 am CDT

 

Inspections play an essential role in effectively managing waterfront infrastructure, such that assessing and documenting the conditions of infrastructure ensures that they are adequately maintained for the protection of life, the environment, property, and structure longevity. This work focuses on utilizing remote sensing techniques, namely MBES (Multibeam Echo Sounder), LiDAR, and UAS-SfM (Unmanned Aerial System Structure-from-Motion), to perform inspections of waterfront structures and shorelines. These advanced methods produce high-resolution point clouds that are merged to create seamless bathymetric/topographic models with detailed representations of structures and other three-dimensional (3D) features. The result is a true ‘snapshot’ of the complete site conditions, which is highly sufficient for baseline level through design level inspections. This conveniently provides unlimited remote access to the information necessary to assess the condition of structures and identify any damaged areas, as required by ASCE Manual of Practice No. 130. In addition to being translated into 2D and/or 3D CAD linework drawings, point clouds can be stored and shared, creating a detailed visual database for infrastructure management. This is an accessible and comprehensive approach to monitoring sites and is ideal for keeping a record of infrastructure conditions throughout each level of inspection. Having this data available increases the effectiveness of inspection datasets and significantly helps agencies manage their infrastructure, both qualitatively and quantitatively.
