  • We offer secure, on-site storage solutions for a range of petroleum, fuel, and chemical products — including the option to store customer-owned inventory. By maintaining both stockpiled inventory and customer-specific materials, we significantly reduce procurement and delivery lead times. This flexibility allows customers to plan more efficiently for time-sensitive projects, manage supply chain variability, and avoid delays due to market shortages or logistical bottlenecks. Whether you're planning a long-term infrastructure project or managing just-in-time operations, our storage capabilities ensure the product is ready when you need it.

  • Leveraging our strong refinery partnerships, we are able to provide unique, made-to-spec fuel blends with the responsiveness and precision required for specialized operations.

    • Example 1: For a prime contractor, we were able to specially blend and deliver a bulk load of JP-4 with an out of specification RVP (Reid Vapor Pressure).

    • Example 2: For a government contracted customer, we were able to specially blend and deliver bulk loads of Jet A with a significantly lower, below specification, sulfur content of 0.0010% by weight (10ppm).

    The lead-time for special fuel blending varies by product, but is typically 4 to 6 weeks.
