Marine Construction – St. Ignace, Michigan (Summer 2023)

Walsh Service Solutions executed a high-precision underwater inspection project in the Straits of Mackinac. Utilizing Remotely Operated Vehicle (ROV) technology, our team performed critical infrastructure surveys at significant depths to ensure the structural integrity of vital regional pipelines.

Project Overview

  • Project Value: $442K

  • Timeline: Summer 2023

  • Location: St. Ignace, Michigan

  • Key Metrics: 30 miles of total ROV survey | Maximum depth of 295 feet | Two 5,000’ pipelines

Project Scope & Operations

  • ROV Survey Missions: Deployed advanced Remotely Operated Vehicles to conduct comprehensive underwater inspections of two parallel pipelines, each approximately 5,000 feet in length.

  • Deep-Water Inspection: Managed technical operations at maximum depths of 295 feet, navigating the complex currents and thermal layers of the Straits.

  • Structural Quality Control: Performed detailed inspections of all pipeline supports, providing high-resolution data and precise quality control reporting for every critical contact point.

  • Regulatory Compliance: Executed all missions under significant regulatory oversight, ensuring that data collection and reporting met the stringent safety and environmental standards required for Great Lakes infrastructure.

The Result

The 30-mile survey was successfully completed in the Summer of 2023, providing the client with a definitive assessment of the pipelines’ condition. By delivering high-fidelity visual and structural data from nearly 300 feet below the surface, WSS enabled informed maintenance decisions and verified the ongoing safety of these critical assets.
