JSI Alliance delivers safe and efficient heavy-lift installation for Dahej berth expansion

The JSI Alliance is proud to have successfully completed a major project in India for client Afcons Infrastructure Limited. Afcons was contracted to construct a new liquid cargo berth for Gujarat Chemical Port Ltd. (GCPL). The JSI Alliance was contracted for the execution of critical heavy lifting operations for the development.

Calling upon the expertise of a wide range of internal disciplines, the JSI Alliance developed a solution fully aligned with the requirements of the project. The Alliance mobilised the heavy-lift vessel (HLV) Jumbo Javelin.

The heavy-lift vessel enabled safe and efficient execution by providing a single platform for the transport and installation of prefabricated structures. Mobilisation commenced on 3 November and took place over a period of fifteen days. During this time, the JSI Alliance equipped the Jumbo Javelin with a flyjib that enabled her to perform the necessary lifting scope.

The vessel was also outfitted with an eight-point mooring spread tailored to the seabed and tidal conditions of the project location. Creating sufficient holding force in such a restricted area required utilisation of 17 t anchors and 64 and 52 mm mooring lines with a Minimum Breaking Load of approximately 300 t per line.

The Jumbo Javelin was equipped with custom-made 250 t winches. It was determined that eight, in place of four, winches should be installed to provide a back-up wire, ensuring safety and redundancy.

Robert de Waard, Project Manager at the JSI Alliance, said, “The successful completion of this project is a testament to the teamwork, expertise and commitment of everyone involved. By drawing on the shared resources and capabilities of the JSI Alliance, we were able to develop a solution tailored to the complex site conditions and deliver the project safely and efficiently." 

“Of course, we are also extremely grateful to Afcons for placing its trust in the JSI Alliance. Our two teams have worked together closely throughout the project, with Afcons being involved, and providing expert guidance, in all aspects. We have enjoyed the collaboration and look forward to working together again in the future.”
