CEMEX UK Marine Limited signs contract with Damen for first Marine Aggregate Dredger (MAD) 3500

Marine Aggregate Dredger to futurise fleet

On 19th December in Southampton, Laurence Dagley, Director CEMEX UK Marine Limited signed a contract with Frank de Lange, Regional Sales Director of the Damen Shipyards Group for the delivery of the first Damen Marine Aggregate Dredger (MAD). The vessel, which will be built at Damen Shipyards Galati, in Romania, is designed to extract sand and gravel from the sea bed up to depths of 55 metres, including in the challenging conditions experienced in the North Sea.

The MAD is the result of extensive market research and customer consultation. A new, future-facing vessel of this type is aligned with an aggregate industry faced with an aging fleet of vessels and an increased focus on marine activity.

CEMEX UK is a leader in the building materials industry with over 3,000 employees, supplying aggregates, cement, concrete and other building solutions. The company has a pre-existing relationship with Damen, having utilised the service of Damen Shiprepair Amsterdam for maintenance of their vessels. When approaching Damen, the client had a clear set of requirements, as Laurence Dagley, Director CEMEX UK Marine explains: “We wanted a cutting edge design, something for the 21st century with all the safety, efficiency, environmental and on board comfort credentials this implies. Achieving a maximum uptime within what can be a challenging working environment is also important to us. Damen accepted the challenges that we gave them, delivering a robust yet innovative design that demonstrates the combined experience and ingenuity of our respective teams. Proudly wearing CEMEX colours, this new ship represents the start of our ambition to modernise our fleet over the coming years, to serve the increasing need for marine dredged aggregates in the UK.”

The MAD 3500 design has the optimal balance between payload and efficiency within limited dimensions. With a specific lock passage limiting the vessel’s overall length to 103.5 metres, a deadweight of just under 7,000 tonnes and a speed at loaded draught of approximately 12 knots are still achieved. In comparison to CEMEX’s current vessel, Sand Heron, which the new ship will replace, this translates into an additional 20% of aggregates that can be delivered per trip.

The vessel will boast Lloyd’s Register ECO-notation, courtesy of its green credentials as well as a CAC-3 notation offering a high standard of crew comfort.

The optimal uptime the client required comes courtesy of a number of features. Included is exceptional seakeeping behaviour, offering crew comfort in rough seas and the capability to work in heavy weather conditions. The bow is enclosed, protecting deck equipment and reducing green water ingress into the cargo hold. A user-friendly approach to maintenance also helps to maximise uptime. All dredge pipes are situated above main deck level for safety, as well as easy inspection and crane reach. Besides this, the modular construction of the Damen designed and built dredge systems makes for the easy replacement of wear parts on the piping and screening installation.

Damen regional sales director, Frank de Lange says: “We are honoured to work with CEMEX on this innovative project. At Damen we are always happy to embrace a challenge and this vessel, which includes a number of never before seen features is a good example of that. We feel confident that the MAD has all the attributes required to bring the aggregate dredging fleet up to date and into the future. We’re looking forward to seeing the first MAD in action at the end of 2019.”

DAMEN HOLDS KEEL-LAYING CEREMONY FOR 'CEMEX GO INNOVATION’ AT DAMEN SHIPYARDS MANGALIA

Damen Shipyards Group recently held a keel-laying ceremony for the CEMEX Go Innovation at Damen Shipyards Mangalia in Romania. The vessel is the first Damen MAD – the next generation of marine aggregate dredgers. The construction of the new vessel is drawing upon collaboration with multiple companies within the Damen Group, as well was with external partners, working together towards the development of a new standard in marine aggregate dredging.

Damen has designed the future-proof vessel for long-lasting durability for operations in North Sea conditions over the coming decades. Particular attention has been paid to sustainability, safety and performance. The MAD will extract sand and gravel from the seabed at up to -55 metres.

During the ceremony, CEMEX Marine Fleet Engineering Manager Mark Williams undertook the traditional role of welding the coins. On this occasion the coins used were a British Pound, a Dutch Guilder and a Romanian Leu, commemorating respectively the regional base of the client, the home country of the shipbuilder and the location of the shipyard. Kurt Cowdery, Director CEMEX Marine Aggregates said, “This is a fantastic investment for the future, allowing us to safely source the materials we need and enabling us to develop and grow in the UK and Europe.”

Damen Area Director Frank de Lange said, “This is an important milestone in the construction of this, the first new Marine Aggregate Dredger. We are very much looking forward to the coming construction and to delivering the vessel to CEMEX next year – and also to seeing CEMEX Go Innovation in action, demonstrating her strong credentials.”

The keel-laying is the first to take place since Damen began the operational management of the shipyard now known as Damen Shipyards Mangalia in July this year. The yard, on the Black Sea coast, has three drydocks with a total length of 982 metres and 1.6 kilometres of berthing space. The 48 and 60 metre wide docks provide Damen with the capacity to cater for larger maritime vessels and structures.
