By studying the existing vessels in the Caspian Sea and repairing them and examining shipyards in the Caspian Sea, it was concluded that in the western region of Gilan province (Bandar Anzali), it was necessary to build a shipyard complex It should be noted that these shipyards have the necessary skills and expertise in designing, constructing, scraping and repairing the middle and long term types of commercial vessels, and, on the other hand, the limitations of other factories located on the margin of the Caspian Sea on spatial and temporal dimensions and Tonage also fixes.

The removal of spatial constraints means that the capability of dewatering and watering is possible at any point in the north and south of the country. In other words, in every place in Iran, there is a problem of floating floating water and there is a possibility of watering in the direction of temporary and permanent repairs in that area. This is a commonly used method of airbags (air cushions) in the world.

The tonnage limit means that vessels over 3000 tons that are not capable of dehydration in other factories can be removed and that floats are accepted.

Following the studies on their displacement and their needs and capabilities in the Caspian Sea, they decided to build a 7th Azar martyr shipyard on the western strip of the Caspian Sea near the city of Bandar Anzali. With the expertise and expertise of its personnel, the factory has the ability to repair all submarines and submersible floats. After examining the need for measurement and finding the required area for a shipyard, it should be checked for the needs of the region. Check the terms and conditions for the factory establishment.

The preparation of the shipyards of the 7 th martyr Azar "Nadaja" was started under the authority of Nadaja transportation services and with the direct command of Amir Nadezhda Command on 10/19/92 . This property complex has an area of ​​about 4 hectares, including parking of boats, niches, warehouses, personnel premises, car parks and more.
