Navigation and radiocommunication equipment in Connection with flagging in or re-flagging


The BSH assumes that safe operation of the vessel is ensured if valid documents of the former Flag State confirming compliance with SOLAS requirements are available.

On-board inspections are not required if proof is furnished that only type-tested and approved equipment has been installed, and a survey conforming to IMO Resolution A.746(18), as amended by Resolution MSC83(70), has been carried out. Acceptable proof is considered to be type examination certificates or declarations of conformity according to the EC marine equipment directive, reviewed plans, certificates of conformity with the plans issued by the Flag State performing the initial survey, and certificates of the last Flag State confirming correct functioning of the equipment. If the latter certificates are older than one year in the case of passenger vessels or five years in the case of cargo vessels, or older than the last renewal survey, shipping companies will be requested to arrange for functional tests to be carried out by the BSH or one of its recognised organisations. If such recognised organisations do not exist in a foreign country, the BSH may use the services of agents. In such cases, the shipping companies receive special forms from the BSH and are asked to have them completed by certain organisations.

In connection with the re-flagging

  • of former German-flagged vessels, surveys by a BSH surveyor are only necessary if the vessel has been converted or refitted after the last BSH survey. It has to be documented that any deficiencies that existed when the vessel’s registration was cancelled have been corrected. New applications have to be submitted for expired exemptions. Renewal surveys of the navigation and radiocommunication equipment should be carried out immediately by the BSH or one of the BSH’S „recognized organisations“. In such cases, the BSH may use the services of agents if such recognized organisations do not exist;
  • of vessels whose plans were reviewed by the BSH during the construction phase, but which were not surveyed by the BSH, such vessels have to be surveyed either the BSH or by one of its „recognised organisations“ in order to check whether the navigation and radiocommunication equipment has been installed as planned and functions according to plan. The BSH may use the services of agents if recognized organisations do not exist;
  • of vessels which are completely unknown to the BSH, the BSH has to perform a survey to check the status of installed equipment. Following an assessment of the equipment, shipping companies either obtain a certificate from the BSH confirming that the equipment meets requirements or are requested to modify the equipment to conform to international Conventions. Also in such cases, the BSH may use the services of agents if recognized organisations do not exist. If a functional test has not been carried out during the survey, the shipping company will be asked to have the test carried out by the BSH or one of its „recognised organisations“.

The BSH informs the See-BG about the assessment of the navigation and radiocommunication equipment.
