Marine Import Terminals - Engineering and Construction


TransTech Energy's marine supply terminals support the efficient receipt, storage and distribution of large volume NGLs and LPG (propane, butane and related hydrocarbons) supplies.

Our marine terminals facilitate rapid unloading of incoming ship and barge deliveries; provide large volume intermediary bulk storage; and support MC331 truck transport operations for further distribution of product down the supply chain.

Serving large NGL and LPG suppliers/importers and buyers, we offer both turnkey and custom configured marine terminals to support the broadest range of requirements and meet the unique challenges of your most demanding operations.

Our expert engineering and design teams can accommodate your unique terminal demands and deliver an efficient solution based on your specific needs including available land/foot-print, minimum liquid volume received at each consignment, temperature and pressure requirements, distribution network, storage capacity needs and other variables to effectively manage your NGL and LPG inventory—and maximize your ROI.

Backed by over five decades of experience, TransTech Energy is a trusted partner to NGL and LPG importers and buyers in addressing the unique needs of ship and barge-delivered liquefied hydrocarbon gases, including all stages of product distribution—from unloading, fuel separation, water removal and the addition of odorant to storage and distribution of purity product

  • Ship/Barge Unloading
  • Storage Tank Loading
  • Large Capacity ASME Storage Tanks to 120,000 Gallons and More

By utilizing our own ASME pressure vessel fabrication facility, we’re able to deliver new and custom large capacity NGL, LPG, propane, and butane storage vessels of up to 120,000 gallons and more—with short lead times—a promise other terminal suppliers just can’t make.

To save even more time, consider sourcing your NGL/LPG storage tanks from our own in-stock, ready-to-ship new and used tank inventory.


You can accelerate your project further by taking advantage of our prefabricated modular installation options. We’ll preassemble and test your complete project ahead of shipping.

On-site, you’ll receive everything you need to install your marine terminal, including P&IDs, construction/fabrication drawings, and required major equipment installation, operating, and maintenance manuals.

We build your marine terminal project into readily installed modular skids – loading/unloading options, pumps, compressors, automation, and controls. All piping is NFPA 58 and API 2510 compliant and preconfigured for easy installation.

Security systems, gas leak detection, fire fighting systems, and all other safety equipment can be specified as needed. We provide a complete equipment package to support all of your requirements for all of your projects.


For one-step installation and predictable schedules, hand off your installation to our team of qualified and trained field professionals and consider the job done. We’ll complete your project from start to finish, including commissioning, startup, and training.
