INS Sarvekshak today reached Dar-es-Salaam, a major city and commercial port of Tanzania.
It will undertake a "pioneer survey" of Pemba Island, which will include surveys of the Port of Wesha and Kiuyo and Pemba Channel in Tanzania, Navy spokesperson Capt D K Sharma said.
After completing the survey in the waters of the African nation, the ship will proceed to Port Louis in Mauritius in December for a survey of the Grand Port.
"The joint survey will be conducted with the naval personnel of Tanzania who have been trained in India," he said.
INS Sarvekshak is a specialised survey ship of the Indian Navy and is fitted with state-of-the-art equipment like deep sea multi beam echo sounder system, side scan sonars and a fully automated digital surveying and processing system.
In addition, the ship carries a Chetak helicopter which would be extensively deployed during the survey.
