What is a "Convolt Tank"? It is an outdoor storage tank for hazardous materials that integrates an oil containment berm, featuring a very robust structure capable of withstanding heavy rain, floods, typhoons, earthquakes, tsunamis, heavy snowfall, and salt damage. It has been recognized for its high specifications in various aspects such as "shortening construction periods, maintenance management, and lifecycle costs," contributing to the second stage of public infrastructure. [Introduction of Case Studies] We would like to introduce the case of Izumi Co., Ltd. (headquartered in Sendai City) and their private refueling station. Due to the nature of Izumi Co., Ltd.'s business, vehicle fuel is essential during disasters. Having experienced the fuel shortage issue during the Great East Japan Earthquake, they implemented this tank with the goal of achieving "overwhelming BCP measures." "Nothing is best. However, to ensure that we do not regret it when something happens next time."

[Introduction of Case Studies] We would like to introduce the case of a private refueling station of Niigata-based Nakajo Transportation Co., Ltd. The introduction at the Kashiwazaki Sales Office, which had experienced inconvenience for a long time, is the first instance. Due to its maintenance-friendly design and shortened construction period, it has been implemented at a total of five locations over three years since 2021.

What is a "Combault Tank"? It is an outdoor storage tank for hazardous materials that integrates an oil containment berm, featuring a very robust structure capable of withstanding heavy rain, flooding, typhoons, earthquakes, tsunamis, heavy snowfall, and salt damage. It has been recognized for its high specifications in various aspects such as "shortening construction periods, maintenance management, and lifecycle costs," contributing to the second stage of public infrastructure. [Introduction of Case Studies] This is an example of contributing to the recovery and reconstruction of areas affected by the Great East Japan Earthquake. One of the strengths of the Combault Tank is its ability to reduce the volume of on-site construction work. While this case is from after the disaster, preparing Combault Tanks in advance is also one of the disaster mitigation measures. *For more details, please download the PDF or feel free to contact us.*

The "Combustible Tank" is the first certified tank for "protected flammable and combustible liquids for aboveground installation" under the U.S. safety standard No. 2085, and it also receives various regulatory exceptions under U.S. fire laws. In recent years, environmental issues have come to the forefront, and the "Soil Contamination Countermeasures Act" has been enforced since February 2003. As a result, it is believed that the mainstream of liquid fuel tanks will shift from underground buried types to aboveground types. The U.S. Combustible Company, commissioned by U.S. fire authorities and the Environmental Protection Agency, has repeatedly conducted various tests and, after many years, completed the "Combustible Type Aboveground Fuel Tank." 【Features of the Hazardous Material Outdoor Storage Tank 'Combustible Tank'】 ■ Elimination of the need for oil containment dikes ■ Easy installation (reduction of installation costs and shortening of construction periods) ■ Easy maintenance (reduction of maintenance costs and management effort) ■ Resistant to fire, typhoons, earthquakes, floods, salt damage, and external impacts ■ Structure that thoroughly eliminates the possibility of oil leakage *For more details, please download the PDF or feel free to contact us.
