Tanks & vessels often represent a challenge for transport, especially when it goes for large storage or process tanks for various industries: oil, food, water treatments, chemical, etc.
The majority of tanks are top big to move them by road to distances over 100 km. Challenges start with excessive width, hight and probably weight, but that is however is rarely a case. Traffic can be suspended, wires lifted and signs removed - nothing impossible would someone argue.

That is why manufacturers are often granted for nearby or local projects benefiting from cheaper logistics and thus possessing greater sales margins.
