First of Its Kind LCO2 Barge Design Approved for U.S. Operation

“Articulated tugs and barges (ATBs) are popular and effective in the U.S. for the carriage of petroleum products for several reasons, and those advantages hold true for LCO2 vessels as well. We look forward to the continued detailed development of the design, including designing the tug to utilize green methanol or other green fuels and technologies. We thank ABS for their valued partnership on this project, as well as other engineering contributors like Corban Energy Group and Herbert Engineering Corporation.” Source
Low-carbon or Zero-carbon Fuel Solutions

Herbert Engineering has a history of innovation; the current challenge, the third great innovation in maritime propulsion, is to transition to low-carbon or zero-carbon fuels. HEC prides itself on being a leader in cost-effective solutions that are environmentally friendly and advance the progress of shipping in this country and around the world.
Cutting-edge Technologies

We pride ourselves on being able to work with our clients to implement the most cutting-edge technologies on board their vessels, especially concerning environmental regulations.
Highly motivated

People are highly motivated because they own the company, have a say in its direction, and benefit from its success. We are a multi-disciplined engineering company, from call form development to evaluating cargo containment systems, propulsion systems, reliquefaction systems, and everything an LNG carrier would include.
HEC consistently excels in:
Decarbonization & Regulations – Authoritative MEPC summaries and guidance on lifecycle emissions.
Fuel Strategy – In-depth comparative studies spanning multiple fuel types for diverse vessel platforms.
Commercial & Government Projects – NSMV design and retrofit expertise backed by technical papers.
Software Tools – Industry-grade stability/load and salvage engineering solutions.
Innovative Research – Engagement in groundbreaking studies involving nuclear propulsion for commercial shipping.
HEC’s instrumental role in both design review and on-site supervision for the U.S.’s largest domestically-built containerships.
Herbert Engineering Corp. has been engaged with Matson in an engineering support role since concept development… HEC also hosted the site supervision/inspection services through the entire construction process at Philly Shipyard Inc. “Proud to be part of this build from Philly Shipyard Inc.” – Joo “Matthew” Kim, Philly Shipyard
“Green ship technology”
HEC supported Matson from concept to delivery on the Daniel K. Inouye – the largest U.S.‑built containership with “green ship technology” at the time.
