What Harbor Docking and Towing does
Harbor Docking and Towing (HDT) is a privately-held, family-owned tugboat operator founded in 1955 and headquartered in Lake Charles, Louisiana. The company provides harbor towage, vessel docking, undocking, and ship-assist services to commercial shipping on the Calcasieu Ship Channel — the seventh-busiest US waterway by tonnage, handling more than 107 million tons annually — and at the Port of Point Comfort, Texas, where HDT has operated since 1986. The current fleet comprises seven tractor tugs, including two hybrid Z-drive vessels (RALPH and CAPT. ROBB, delivered 2019) built to reduce fuel burn and emissions relative to conventional tugs.
Revenue is generated on a per-assist tariff basis from shipping companies moving cargo through the channels HDT serves, supplemented by longer-duration contracted work. In 2026 the company materially extended its service scope through Green Tug Towing (GTT), a joint venture with Saltchuk Marine that holds a 20-year, $300M+ towage contract with Woodside Energy tied to a new Calcasieu Parish LNG export facility, supporting approximately 160 local jobs and first LNG targeted for 2029. HDT is led by President John Buchanan and operates under USCG Subchapter M regulatory compliance.
The combination of a multi-decade harbor towage legacy on a top-ten US waterway with a long-duration LNG export anchor contract positions HDT as a hybrid traditional-asset / contracted-cash-flow operator. Customer mix blends a high-volume, fragmented base of general shipping clients with a single large contracted counterparty (Woodside) for the LNG terminal stream.

Harbor Docking and Towing competitors and assessment
Company assessmentDirect peers
- Saltchuk Marine / Foss Maritime: Parent of Foss Maritime and HDT's JV partner in Green Tug Towing. Saltchuk Marine operates one of the largest US tug and barge fleets (including Foss Maritime on the West Coast and Hawaii) and is the natural counterparty for harbor towage consolidation. The GTT partnership makes Saltchuk both a peer and a strategic partner, with highly comparable harbor and offshore towage services.
- Crescent Towing: Gulf Coast tug operator providing harbor ship-assist and escort services across Louisiana and Texas ports. Crescent competes with HDT in overlapping Gulf harbors and offers directly comparable vessel configurations and customer segments.
- Bisso Marine: Gulf-based tug, towing, and salvage operator providing harbor ship-assist, docking, and offshore towing services. Bisso's overlap with HDT in Gulf harbor towage, including support for petrochemical and energy customers, makes it a directly comparable regional peer.
- McAllister Towing: Privately held, family-owned harbor towing operator founded in 1864, serving East Coast and Gulf ports with ship-assist and escort services. McAllister's ownership structure (privately held, multigenerational) and service scope (harbor towing, ship assist, LNG/chemical carrier escort) closely mirrors HDT's positioning.
- Moran Towing Corporation: One of the largest US harbor towing companies, operating a fleet of over 100 tugboats across the East Coast, Gulf, and Great Lakes. Moran competes directly with HDT in harbor ship-assist and docking services for commercial vessels and has comparable Z-Drive tractor tug fleet configurations.
- Signet Maritime Corporation: Houston-based tug and marine transportation operator with a Gulf Coast harbor towing fleet serving petrochemical, tanker, and bulk customers. Signet's geographic overlap with HDT in Texas/Louisiana and comparable vessel mix make it a directly comparable regional peer.
- Bouchard Transportation: Gulf Coast tug and barge operator with a long history in the Calcasieu region and broader US waters, providing harbor towing, ship-assist, and barge transport services. Bouchard's overlapping Gulf footprint and comparable fleet of harbor tugs make it a direct regional peer to HDT.
Broad incumbents
- Seabulk Towing / SEACOR Marine: Diversified marine services operator (NYSE: SMHI) with harbor towing, offshore support, and broader marine logistics. Seabulk overlaps with HDT in Gulf harbor towage but operates at materially greater scale and across broader service categories, positioning it as a broad incumbent.
