Viking - All Things Ship Structures

Viking provides maritime solutions for conventional and specialized structural design, analysis, and verification of ships and offshore assets. We create highest-quality structures while reducing the cost of construction and maintenance. We employ the same organized software and workflow process across our offices, resulting in high-quality output delivered in a fast and reliable time frame.

Viking was founded in 2000 to operate in shipbuilding industries and serve military and naval vessel shipbuilders and designers, commercial shipowners and ship operators, and offshore oil and gas companies. Our experience, coupled with the consistent application and development of innovative computer programs, helps our engineering teams make sound and consistent decisions about our clients’ ships and offshore assets. Analyses are based on classical design rules and advanced tools for structural modeling, loading, and assessing conventional and high-speed monohull and multihull vessels.

We are privileged to work with many different clients in the marine industry, including the US Navy, the US Coast Guard, NASA, the Military Sealift Command, oil and gas companies, and shipbuilders and ship operators. We also provide structural design and analysis services to owners and builders of commercial ships, including inland and oceangoing barges, heated cargo barges, tankers, container ships, and cruise ships.

Viking is composed of experienced mechanical engineers, naval architects, marine engineers, civil engineers, software developers, and business professionals.

Our computer programs and team spirit are named after figures in Nordic mythology. This is in line with our Viking traditions that have endured for more than a thousand years:

  • SAGA (Structural Assessment Graphical Application) is a computerized tale of “structural events” created, assessed, and safeguarded for current and future learning. It is just like the Viking-era sagas that are preserved to this day,
  • ODIN (Optimum Design Integration Network) is named after the Viking leader Odin who sends out his pair of ravens, Hugin (Old Norse for “thought”) and Munin (Old Norse for “mind”), all over the world to gather information. In our case, structural computing solutions created by our network of computers and team members are being monitored by Odin to collect and present data and to learn from the data to make sound decisions,
  • THOR, son of Odin and Fyorgyn, is the most powerful of all to take action, going beyond boundaries, and leading teams. Each of our Viking team members, like Thor, embodies great strength of character, indispensable leadership qualities, and an ability to be a strong team player. These are the true qualities of Vikings at all times – then and now.


We do all types of structural design and analysis for conventional ship, multihull, and high-speed vessel ship structures. These include:
