Mumbai: For the first time since its opening 16 years ago, the iconic 4.7-km Bandra-Worli Sealink will undergo a detailed underwater inspection using advanced submersible remotely operated vehicles (ROVs). This initiative aims to capture high-definition visuals of the submerged sections of the structure, enabling experts to identify cracks and defects for necessary repairs.
According to a senior official from the Maharashtra State Road Development Corporation (MSRDC), “We have invited tenders from the agencies for the work and will be opening the same on January 25. Once appointed, the agency will complete the inspection and report submission within six months.”
Stating that the estimated cost for inspection is Rs 7 crore, the official said that they carry out such inspection every five years. “Only thing is this time, we invited tenders for the inspection since earlier the agency entrusted with the job to collect the toll used to carry out the process. Now, we decided to have a different agency to collect toll and do the inspection l,” the official added.
This cutting-edge technology marks a significant upgrade from previous inspection methods. “This is a new approach to ensuring the health and safety of the sea link,” the official said. In earlier assessments, scuba divers were employed to clear marine growth and examine the structure, and their expertise will likely be utilized again during this process.
The Bandra-Worli Sea Link, inaugurated in June 2009 after nearly a decade of construction, rests on 179 foundation piers, each supported by multiple piles tailored to the pier’s design and positioning. The upcoming evaluation will include a comprehensive examination of underwater components, non-destructive testing, scour surveys, and ultrasonic thickness measurements of steel elements.
This inspection underscores the commitment to maintaining the structural integrity of one of Mumbai’s most iconic landmarks, ensuring its continued service to the city’s commuters and preserving its engineering marvel.
