Dredging of Royal Quays Marina Approach Channel by Van Den Herik

About

North Tyneside Council awarded a contract to VAN DEN HERIK for maintenance dredging and disposal of material outside Royal Quays Marina, from the lock to the river channel.

The maximum volume to be dredged and disposed was 20,000m3, using self-propelled split hopper barges loaded by a spud leg backhoe dredger.

The scope included pre- and post-dredge hydrographic surveys.

The preferred dredging method was backhoe, with other methods subject to MMO consent, and water injection dredging was not acceptable.

The MMO licence referred to sea disposal, while land disposal could be offered if all necessary licences were included in the price and an existing disposal site was provided.

The contract value was AUD 218,800.
