Client: ECC Division, L&T

Gujarat Industrial Development Corporation (GIDC) is planning to develop two industrial estates at Vilayat and Dahej near Bharuch along the Gulf of Khambhat. The effluents from both these estates are to be treated and disposed into the Gulf of Khambhat using a suitable Marine Outfall System. L&T-ECC Division are the contractors for the construction of the effluent disposal system. L&T-RAMBØLL, as contractor's engineer, carried out the detailed design of the Marine Pipeline and Outfall System. 

The broad Scope of Work for the present study are related to Detailed Design and Studies for the Construction of a 4.5 km long Sea Outfall into the Gulf of Cambay involving:

• Specifications and Supervision of Seabed Surveys and Oceanographic Investigations

• Specifications and Supervision of Geotechnical Investigations

• Computerized Hydrodynamic model studies to finalize Diffuser Relocation and to satisfy specified dilution criteria using MIKE 21

• Hydrostatic, Hydrodynamic, Structural Design of Outfall system

• Geotechnical Stability of outfall system

• Design of anti scour protection for pipeline including rock armouring and gravel fill

• Pipe flow analysis and Diffuser Design

• Design of Stringing Yard and Beach Chamber

• Pipe Stress Analysis- Installation, Operational & Design

• Preparation of Project Installation Manual and Procedures outlining construction methodology

• Preparation of As built Drawings based on as built information.

Client: Gangavaram Port Ltd.

Gangavaram Port Ltd. is developing a Greenfield port at Gangavaram near Visakhapatnam City. Gangavaram Port Ltd. appointed L&T-RAMBØLL as their consultants to carry out mathematical model studies as part of the detailed project report for the development of the port. 

The scope of services are as follows:

• Carry out wave hind cast study by collecting and analysing offshore wave data to arrive at both short term and long term wave statistics for operational and design conditions.

• Carry out Near Shore Wave (NSW) simulations to transform offshore wave conditions (both short and long term) to nearshore areas of interest in the harbour layout proposed by others. 

• Carry out wave tranquillity studies to assess the tranquillity afforded by the proposed layout, at the location of berths and to optimise the length and alignment of breakwaters.

• Carry out sedimentation study to estimate the alongshore sediment movement (littoral drift) and sedimentation in the sand trap and navigational channel.

• Carry out real time Navigation simulation study, to optimise the layout and design of the navigational channel proposed by others.
