Payra sea port is the 3rd sea port of Bangladesh located approximately between latitude 21015’-2200’ North and longitude 9000’-90039’ East of the bank of Rabnabad Channel under Kalapara, a sub-district of Patuakhali. In order to increase the economic activities in the central zone and meet the future demand, Payra Port Authority Act 2013 was passed in National Parliament on 10 November 2013. Payra Sea Port has almost 75 Km long inner channel in general has enough water depth for berthing the deep draught vessels but the long outer channel is too shallow for port operation and a designed channel needs to be dredged and maintained to a certain depth that is safe for navigation. As such, capital and maintenance dredging are important components for developing the Payra Sea Port.
