Bulgarian Register of Shipping (BRS) was founded as the national Classification Society of Republic of Bulgaria in 1950. The Inspection Offices, in Varna, Bourgas and Rouse provide supervision by BRS in the main shipbuilding and industrial centers of Bulgaria. BRS has its own technical requirements in line with the stipulations of International Conventions, which provide safe navigation of ships in accordance with their intended purpose, the safety of life at sea and at inland waterways, the safety of the cargo transported and the preservation of marine environment; it also carries out technical supervision for the implementation of these requirements and classification of all ships. The activities on the supervision are performed on the basis of the Rules of BRS, with the main purpose to ascertain whether the ships and containers, subject to supervision, as well as the materials and products, intended for the construction and repair of ships and ship equipment, comply with the Rules and any additional requirements.
