Kakinada Deep Water Port (An Asian Development Bank-aided Project)

Home / Projects / Design & Project Management - Port & Maritime / Kakinada Deep Water Port (An Asian Development Bank-aided Project)

Client: Director Of State Ports, Government Of Andhra Pradesh

Location: Kakinada, Andhra Pradesh, India

HOWE are responsible as the Consultants for Planning, Detailed Engineering, Construction Supervision and Project Management for the New Deep Water Port at Kakinada.

Nestled in a cove 73 NM South of Visakhapatnam Major Port and 277 NM North of Madras Major Port on the East Coast, Kakinada Bay was historically a Lighterage Port. The State Government had undertaken the development of a Deep Water Port at Kakinada with Loan Assistance from Asian Development Bank (ADB).

The Deep Water Port caters to 20,000 DWT vessels in the First Phase which can be deepened later to berth 60,000 DWT or bigger ships.

HOWE, having been commissioned by the State Government to review their original design earlier finalised and approved, had improved upon the design to provide unlimited scope for future expansion after extensive hydraulic model studies. The revised layout conceived and designed by HOWE was accepted both by ADB and the Government of Andhra Pradesh as a better alternative.

In the First Phase two General Cargo Berths, one Liquid Cargo Berth were developed. The Master Plan envisages development in stages upto 7-Off-shore and 6-On-shore Berths, with possibility to expand further upto 21 berths in all.

The Kakinada Bay is covered entirely by 8 to 10 m of soft marine clay with low shear strength and high compressibility. As part of the Ground Improvement Scheme, Geo-textiles to the tune of 144,700 sq.m and 100 mm wide Vertical Band Drains (“MEBRA”) to the tune of 1.24 million running metres have been successfully placed to increase the shear strength of foundation soil from 7 kPa to 70 kPa by stage-loading.
