February 24, Colombo (LNW): This month, Hambantota International Port (HIP) initiated a dredging operation to restore its harbour to its original depth.
The maintenance, which began in early February, is expected to last for about two months.
The primary objective is to return the port to its designated depth, thereby ensuring the safety of vessel navigation and the efficient operation of the harbour.
Over time, silt tends to accumulate in harbours, which necessitates regular dredging. HIP’s navigation channel is meant to be 17 metres below sea level, but silt deposition has gradually reduced this depth in certain areas.
To maintain operational safety and efficiency, dredging is required to restore the harbour to its intended specifications, allowing for the safe passage of large vessels. As Capt.
Ravi Jayawickreme, CEO of Hambantota International Port Services (HIPS), explained, this process is essential for the continued safe operation of the port.
Before starting the dredging work, a detailed bathymetric survey was conducted in collaboration with the Sri Lanka Navy’s Hydrography Service.
This survey identified specific areas where silt had accumulated. Following the survey, a tender process was held to select the best-suited contractor for the job.
The dredging operation is being carefully managed, with all necessary environmental permits in place from the Central Environmental Authority, Marine Environmental Protection Authority, and the Coast Conservation and Coastal Resource Management Department.
The dredged material is being dumped 11 nautical miles offshore, ensuring minimal impact on local fishing activities. The Port Control unit is closely monitoring the operation to ensure compliance with safety and environmental standards.
Datta Gunasekara, Chief Specialist Engineering at HIP, noted that while silt accumulation is typical for coastal areas, the port is prioritising the restoration of its declared depths as quickly as possible.
The dredging contractor is using advanced equipment to collect the silt, which is then transferred onto barges for disposal. The dredging schedule is flexible and will be adjusted to accommodate incoming vessels, ensuring their safe navigation.
Environmental considerations are a key aspect of the project, with initial tests confirming that the dredged material is largely sand and mud, without harmful substances.
Once the dredging is completed, another survey will be conducted to confirm the harbour’s depths have been restored.
HIP, which opened in 2010-2011, remains committed to upholding high standards of operational safety, environmental protection, and sustainable development, ensuring its continued role as a vital maritime hub.
