Orion Marine Group has recently completed the commissioning of its newest dredge, Lavaca. The christening of the Dredge Lavaca took place on November 10th 2022, in Port Lavaca, Texas at 1:30 in the afternoon. Over the course of the past 15 months, the dredge has undergone a complete rebuild, including detailed engineering by The Shearer Group, Inc. to meet Orion’s requirements for lengthening and widening of the hull by Southwest Shipyard, L.P. Additionally, advancements to the dredges ladder, accommodations, and operating systems were made in order to continue to provide exceptional dredging service to its clients and industry partners in both the public and private sectors along the Gulf Coast. The Lavaca is scheduled to begin work in November 2022 and will take part in the continued maintenance of waterways, deepening & widening projects for years to come.

State-of-the-art Technology

survey monitoring systems, dredge pump, draw works, and cutter automation systems with fully electric draw works and spud winch systems, allowing the dredge to operate more efficiently in both maintenance and virgin material projects. The design of the dredge from its modular quarters, walkways, access and egress points, ventilation, handrail & fendering systems have all been engineered specifically with an emphasis on “Safety”.

The design improvements that have been implemented to the crew accommodations have reduced the noise and vibrations associated during dredging operations and provide a reprieve for the crew during their rest periods. The open-concept lever room allows for the leverman to monitor and control all dredging systems from a specialty-designed control station with touchscreen displays and floor-to-ceiling windows that provide a 180-degree field of view.

The Lavaca has been repowered with Tier III Marine Gensets supplied by Mustang Cat, to provide a consistent supply of power to the electrical switchboards and controls systems provided by Avid & DSC as well as electrical cabling, lighting, and alarm systems supplied and installed by Rio Marine, Controls & Hydraulics.

The outfitting of the Lavaca with Tier III diesel-electric engines and electric winches provided by Nabrico and Timberland Equipment is another step forward for Orion to continue our commitment to protecting the environment by preventing potential spills and reducing NOx emissions within our operating areas.

Special Thanks

A special thank you goes out to our dedicated team of personnel and contractors that helped make this project possible. Orion’s commitment to Safety and “Target Zero” is also instilled into our vetted contractors and is reflected indirectly in this project, as we have surpassed 65,000 manhours without any lost time incidents or recordable injuries! Congratulations to all involved in this project on this achievement!
