Breakwater works at Vizhinjam International Sea Port, India : an ACCROPODE™ II project
Breakwater works at Vizhinjam International Sea Port - India
The company HOWE Engineering Projects (India) Pvt. Ltd. has been appointed by Adani Vizhinjam Port Limited (AVPPL) as contractor for the construction of Vizhinjam port, located 20 km south of Kerala, India. The project includes the construction of a rubble-mound breakwater using ACCROPODE™ II armour units.
The development of the Vizhinjam International Deepwater Multipurpose Seaport is an ambitious project taken up by Government of Kerala, India. The Port is located on the Eastern coastline and close to some of the main international shipping routes. The port is designed primarily to cater container transhipment (besides multi-purpose and break-bulk cargo) and to become a major transhipment hub for the Indian subcontinent. In this regard, Vizhinjam port is to be protected by a 3 100 m long breakwater reinforced by 2000 ACCROPODE™II units of 5,0 m3.
