Portsmouth Harbor Maintenance Dredging Scheme About to Begin

The Queen’s Harbor Master Portsmouth said in their latest announcement that the surveying operations and maintenance dredging will be conducted in the maintained areas within Portsmouth Harbor and its approach channels from 29 October to 8 November 2017. 

The contractor for the works will be Boskalis Westminster Ltd, using the plough vessel ‘Norma’ with the support vessel ‘Smit Romney’ carrying out survey operations.

“Both vessels will display the appropriate signals when conducting survey and dredging operations. Works will be conducted daily between 07:00 to 19:00,” according to the official announcement.

The Norma can operate in water injection dredging mode or in plough mode, Boskalis said.

The vessel is equipped with plough/bed leveling units in order to support dredging operations to achieve accurate finished levels. She can also be used independently for bed leveling to extend the intervals between maintenance dredging.
