She [HMS Magpie] may be the second smallest vessel in the Royal Navy’s fleet, but this summer she has a big job.
HMS Magpie has just arrived in Portsmouth to carry out bathymetric survey work to keep HMS Queen Elizabeth safe.
She will spend three months surveying the sand and mud on the seabed at Portsmouth harbour, as any shift could cause a threat to the aircraft carrier.
More than three and a half million cubic metres of clay, sand and gravel was removed from the harbour to accommodate HMS Queen Elizabeth.
The survey will check there has been no change in the seabed and it is ready for the arrival of HMS Queen Elizabeth’s sister ship HMS Prince of Wales, which should arrive later this year.
Portsmouth Harbour is one of the busiest in the UK, seeing more than 230,000 vessels come and go throughout the year.
