Sallyport Acquires Louisiana Pipeline Remediation Firm Submar

Submar provides engineered protection systems, including articulated concrete mats, to a nationwide client base of energy and infrastructure operators. The firm maintains a strong market presence by addressing environmental challenges for both onshore and offshore pipelines. According to Kyle Bethancourt, Managing Partner at Sallyport, the investment is driven by industry tailwinds such as aging infrastructure, heightened regulatory oversight, and the rising demand for natural gas fueled by LNG exports.

President Joseph Fournet will remain at the helm of Submar, continuing to lead the firm’s existing management team. Sallyport intends to leverage its midstream sector experience—evidenced by previous investments like T.D. Williamson and Navitas—to accelerate Submar’s growth. Ryan Howard, a Managing Partner at Sallyport, noted that the firm’s strategic support will focus on scaling Submar’s reach while maintaining its established reputation for safety and technical precision.
