Trelleborg Marine Systems has collaborated with ABG Shipyard Ltd, at Dahej in Gujarat, India to create an innovative, bespoke solution for the design and installation of the fendering systems needed to overcome the high tidal variation, underwater current and high wind velocity faced by the shipyard.
The project was required to meet the conflicting demands of having an economical jetty design whilst being able to accommodate high impact loads.
D.N. Mathur, Senior Vice President of Projects at ABG Shipyard Ltd says: “Trelleborg worked with our civil consultant and technical team to develop a custom-built solution, without overrunning on tight project timelines. Overcoming the operational hurdles posed by the rough environmental conditions at the jetty within this timeframe meant a saving of approximately €2 million to ABG.”
Amit Madan, director of the Trelleborg Marine Systems office in Ahmedabad says: “Thanks to Trelleborg’s in-house design and manufacturing capabilities, and the support of the ABG team, we were able to develop an effective solution within a very tight timeframe.”
In this case two piles were connected with a fabricated frame to improve the load carrying capacity of the jetty. Parallel motion fenders were then installed on the centre of these beams to further reduce impact on the structure, thus eliminating conventional fenders.
The beams were designed at Trelleborg’s Design Centre of Excellence in India, which also undertook stress analysis data on the proposed system. The proposal and stress analysis data was reviewed and approved by ABG Shipyard and their structural consultant, as well as being validated by British Maritime (BMT) as a third party verification measure.
