Port of Milford Haven Completes Dredging Project
A £1.5 million dredging campaign to clear the shipping channels and berths at the Port of Milford Haven has been completed.
The work is an essential part of ensuring the waters leading to and around the terminals on the river remain deep enough for some of the larger ships that use them.
Nearly 180,000 tonnes of fine silt and sand have been cleared from along berths and channels in the port over three months. The dredgers have had to work around several major storms over the period between December and March.
“A campaign on this scale is carried out every ten years,” explained the Port of Milford Haven’s Harbormaster, Bill Hirst. “It is vital to dredge in order to keep the UK’s biggest energy port open for business.”
The Port of Milford Haven carries out annual hydrographic surveys of the river bed to monitor build up of silt in the channels.
“We have a legal duty to accurately state the depth of waters in the port,” said Bill. “With data going back several years we have a pretty clear idea how often we need to dredge to make sure those stated depths remain accurate.”
Several dredging vessels were used to carry out the task. The largest was a 26,000 ton, 150m long ship the Bartolomeu Dias. In order to clear behind terminal jetties, the smaller vessel Mimar Sinan was deployed, equipped with a digging bucket capable of lifting more than 40 tonnes of material in one scoop.
