Заказчик: BP Raffinaderij Rotterdam B. V. 2015г.
  • Тип резервуара: 120 000 м³
  • Объем шлама: 6 500 м³
  • Сроки реализации: март-апрель 2015

Сложность проекта заключалась в том, что зачистка не производилась в течении 12 лет, в высокой температуре плавления нефтешлама, а также в большом объеме резервуара.

На протяжении длительного времени ни одна подрядная организация не справилась с поставленной задачей.

Нефтеосадок был приведен в жидкое состояние с помощью мобильного парогенератора. Высокоточные газовые анализаторы были установлены внутри и снаружи резервуара для обнаружения любых выбросов в атмосферу - выбросов не обнаружено.

Заказчику было возвращено 100% нефтепродукта
