A berthing structure of a major port in east coast of India was under deterioration and damaged severely. This structure is reported to have been constructed in the early 1960’s and has already completed its design life. The berth is having a length 180 m and width of 90 m. The berth is designed for a Live load of 2.7 T/m2. The structural members have developed severe cracks now, due to overloading and mechanical operation, chemical attack and corrosion in reinforcement. It is proposed to retrofit the berth at the same location after demolishing the deck components completely and the existing piles up to 1 m below the cut off level for a berth width of 23 m. The proposed 23 m wide berth shall be constructed with new piles and pile sheet pile. The pile sheet pile wall is designed to retain the soil behind the 23 m wide berth. The new structure shall be designed for Live load of 5 T/m2, harbour mobile crane (HMC) with pad (5.5 m by 1.8 m) load 9 T/m2 and Rail Mounted Quay crane with 20 m gauge. The new upgraded terminal facility shall have higher capacity mechanical handling system, which will be cost effective for handling Containers. The present capacity of the berth will be increased from 90,000 TEU per annum to 270,000 TEU per annum. © 2019 Taylor & Francis Group, London.
