Enterprise Hydrocarbons Terminal
The Enterprise Hydrocarbons Terminal (“EHT”) is located on the Houston Ship Channel and provides terminaling services to exporters, marketers, distributors, chemical companies and major integrated oil companies. EHT has extensive waterfront access consisting of seven deep-water ship docks and one barge dock. The terminal can accommodate vessels with up to a 45 foot draft, including Suezmax tankers, which are the largest tankers that can navigate the Houston Ship Channel. We believe that our location on the Houston Ship Channel enables us to handle larger vessels than our competitors because our waterfront has fewer draft and beam (width) restrictions. The size and structure of our waterfront allows us to receive and unload products for our customers and provide terminaling and dock services.
EHT can load refrigerated cargoes of low-ethane propane and/or butane (collectively referred to as LPG) onto multiple tanker vessels simultaneously. Our LPG export services continue to benefit from increased NGL supplies produced from domestic shale plays such as the Permian Basin and Eagle Ford Shale, international demand for propane as a feedstock in ethylene production and for power generation and heating purposes. LPG loading volumes at EHT averaged 483 MBPD, 445 MBPD and 424 MBPD during the years ended December 31, 2019, 2018 and 2017, respectively.
Our current maximum estimated loading capacity for LPG at EHT is approximately 835 MBPD, with 175 MBPD of this loading capacity placed into service during the third quarter of 2019. EHT has the capability to load up to six Very Large Gas Carrier (“VLGC”) vessels simultaneously, while maintaining the option to switch between loading propane and butane. EHT can load a single VLGC in less than 24 hours, creating greater efficiencies and cost savings for our customers. In 2019, we commenced construction on an expansion project at EHT that is currently expected to increase our LPG loading capacity by an additional 265 MBPD. When this latest expansion project is completed in the second half of 2021, EHT will have a new maximum LPG loading capacity of approximately 1.1 MMBPD, or 33 MMBbls per month.
The primary customer of EHT is our NGL marketing group, which uses EHT to meet the needs of export customers. NGL marketing transacts with these customers using long-term sales contracts with take-or-pay provisions and/or exchange agreements. In recent years, the U.S. has become the largest exporter of LPG in the world, with shipments originating from EHT playing a key role.
EHT also includes an NGL import terminal. This import terminal can offload NGLs from tanker vessels at rates up to 14,000 barrels per hour depending on the product. Our NGL import volumes for the last three years were minimal.
EHT also provides terminaling services involving crude oil, petrochemical and refined products. EHT’s assets and activities associated with crude oil terminaling and storage are classified and presented as a component of our Crude Oil Pipelines & Services business segment. EHT’s activities associated with petrochemicals and refined products are classified and described within our Petrochemical & Refined Products Services business segment.
Morgan's Point Ethane Export Terminal
The Morgan’s Point Ethane Export Terminal located on the Houston Ship Channel has an aggregate loading rate of approximately 10,000 barrels an hour. The facility supports growing international demand for abundant U.S. ethane from shale plays, which offers the global petrochemical industry a low-cost feedstock option and supply diversification. By providing producers with access to the export market, the Morgan’s Point Ethane Export Terminal supports continued development of U.S. energy reserves.
