We study a frequency of passing through the global choke points, that is, a dependence on the choke points by means of the sea lane network and the LMIU's vessel movement database. The choke points such as the Straits of Malacca, the Bosphorus Straits, and the Suez Canal are important sea lanes for the maritime transport of energy resource. It is, therefore, necessary to reduce the dependence on the choke points for the transport energy security. We show the effect of the change in transport volume on the dependence.
