Custom Designed Barging Solutions

We maintain high standards for our equipment and, more importantly, for ourselves. We are constantly working to improve our performance and the service level we provide to our customers. Despite our efforts, from time to time, we encounter new cargoes or complex supply chain problems that we don’t offer a solution for, but this is where we shine!

We take pride in listening to our customers to understand their unique needs, and then partnering with them to design solutions that exceed their expectations. Whether it’s as complex as designing and building a fully customized barge for a specialty chemical, or something simpler, like developing special handling and monitoring procedures for a product while it’s under our care, whatever your needs--we’re eager to work with you to find a solution.

Lightering Services

As experts in the transportation of chemicals and fertilizers, our mariners and shoreside professionals have the experience needed to safely conduct direct ship-to-barge cargo transfers, commonly referred to as lightering. We see lightering as a value-add service for our customers that can improve supply chain efficiency & flexibility while minimizing our customer’s exposure to ship demurrage. We bring decades of experience to every transfer and can modify barges to improve efficiency for customers who lighter frequently.
