Damen launches marine aggregate dredger for Hanson

Hanson will use the vessel to conduct offshore aggregate extraction in water depths up to 55 m in the North Sea and English Channel.

Hanson Thames is specifically aimed at achieving the optimal balance between payload and efficiency within the limited dimensions required for the vessel to traverse the Shoreham Lock on the English south coast.

The vessel design will allow it to carry up to 7,000 tonnes of marine aggregates per trip, as well as providing improved fuel consumption, reduced emissions and maintenance savings.

The company said the MAD range applies innovations in maritime engineering to ensure safe and comfortable operations even in adverse conditions. Safety is further enhanced by the positioning of all dredge pipes above the main deck. The equipment itself is protected by the MAD’s enclosed bow.

Damen said the MAD was successfully launched despite production being affected by the Covid-19 pandemeic.

Sales manager Joppe Neijens said Damen combined a robust approach to safety measures with co-ordinated teamwork to continue production. “The measures we have taken include strict hygiene and disinfection routines, and the establishment of shift teams to ensure maximum distance between people working, while keeping to schedule. The project team and yard have done a great job. Together they have taken the necessary measures to keep on track with minimal loss of time. In this way, we are able to maintain our support to our clients.”

Following the launch, Damen will complete work on Hanson Thames, and afterwards undertake commissioning, including of dredge equipment and screening installation from Damen Dredging Equipment in the Netherlands and a dry unloading system from PLM Cranes. The vessel also features Royston Diesel Power’s electronic fuel management system Enginei. Hanson Thames will join Hanson’s existing fleet in Q1 2021.

Hanson is one of Europe’s largest producers of marine-dredged sand and gravel.
