Vessel Of Opportunity “VOOP”

eTrac travels nationally and internationally for our clients & jobs. Since our field of work occasionally needs a vessel, we regularly work with “Vessels of Opportunity”, or “VOOPs” for short. VOOPs are vessels local to the jobsite where we can mobilize our equipment and use for the duration of the project. For one of our recent jobs in Freeport, TX, we utilized a local pontoon boat to survey a river! #eTrac #survey #hydrography

Safety Comes First

eTrac utilizes ISNetworld’s (ISN) Review and Verification Services for independent review and continuous improvement of our Safety Program.

As a global leader in contractor management services, ISN’s detailed and ongoing reviews of our Safety Program ensure that eTrac is exceeding industry workplace health and safety standards. Their teams review various HSEQ documents and information such as written programs, work hours, incidents and injuries to ensure compliance with regulations and client guidelines. To quantify eTrac’s success, they also provide reports that measure our health and safety performance against that of our industry.

eTrac’s commitment to utilizing effective tools for tracking our safety and training practices ensures a safe workplace and culture with a strong focus on safety and quality.

Ocean Cleanup

The Ocean Cleanup has issued an extensive update on their website announcing the assembly of their first cleanup system and upcoming tow test that will take place 40 nautical miles outside of San Francisco. Just five weeks ago, The Ocean Cleanup was signing the lease on their facility and is now getting ready for their first Pacific testing phase. This is the worlds first ocean clean up system and eTrac could not be more excited to have contributed to this effort. eTrac conducted the multibeam survey at their facility, located at the former Naval Air Station in Alameda. We provided a high resolution 3D model of the lagoon where their assembly system will be launched. Thankfully, no obstructions were detected that would prevent the tow out of the system being tested. Please take the time to visit their website and keep up with their timeline and efforts; their cleanup system will be deployed in the Pacific but will have global impacts on our ocean ecosystems health and future.


Glen Canyon Dam 3D Model

This past summer, eTrac teamed up with Autodesk and R2Sonic to collect data using LiDAR, photogrammetry, and sonar technology to create a 3D model of the Glen Canyon Dam and the power plant facility. This model will be used for design, operation and management, asset management, monitoring, security, and public outreach and education. In addition, the model will give U.S. Bureau of Reclamation personnel a better overall understanding of the facility and its interrelated systems.

Beauty on the Bay

eTrac has office locations in California, Washington and Alaska where project planning, data processing, and product generation occurs. We also staff our “mobile offices”, the vessels on which data is collected and QC’d on a regular basis. We are dependent on our fleet of vessels and the employees that spend day after day on the water throughout the west coast supporting the dredging, charting and environment remediation industry. There is a dynamic relationship between data collection on the water and data processing in our office for the overall quality control of our products to our clients.

Remote Surveys at Glen Canyon Dam

eTrac has designed and built a new remotely controlled survey craft: S/V ROVer! This compact, versatile, and highly transportable Remote Operated Vessel is indeed a surveyor’s best friend. Following its first survey at the USS Arizona in Pearl Harbor Hawaii in late August, it was successfully deployed for a high resolution mapping effort at the Glen Canyon Dam in Arizona.

Searching for Hidden Treasures

Recently, eTrac teamed up with the National Park Service to perform surveys around Torpedo Wharf in the San Francisco Bay in preparation for restoration efforts on the horizon. The team will perform several surveys using a variety of equipment to help provide the fullest picture of what artifacts may lay underneath the surface.

Remnants from old piers, military munitions, or even shipwrecks such as the S.S. City of Chester which sank after a collision in the bay on August 24, 1888 are some of the items expected to be found. More modern artifacts such as tires and even a golf cart are the only discoveries to date however.

Maintenance Survey of a Breakwall

eTrac provides high resolution imagery on breakwalls to help keep them maintained. Breakwalls are often constructed atop moveable material which requires them to be constantly monitored for movement or deterioration due to constant wave action. This imagery provides a detailed look at the complete structure of a breakwall in order to determine if repairs are needed.
