Van Oord’s newest addition to its fleet – the self-propelled cutter suction dredger Artemis – was moored in Rotterdam for a few days. Business relations and employees had the opportunity to visit Artemis before it departed for western France for its first assignment.
Hard rock and clay
Pursuant to a contract with the Grand Port Maritime de la Rochelle, Artemis will be deepening the harbour basin and dredging a trench in the access channel to the harbour. Approximately 500,000 cubic metres of very hard rock and clay will be dredged, and Artemis was built especially for dredging work on hard ground.
Stronger position dredging market
The contract for the vessel’s design, construction and delivery was signed with IHC Merwede on 20 December 2010. Pieter van Oord, CEO: ‘Our investment in two self-propelled cutter suction dredgers and two large backhoe dredgers has significantly bolstered our position on the dredging market. This is in line with our strategy to have a very strong position in all segments of the dredging market.’
Spatial spud carriage
Artemis is a robust ship and strong ship. An exceptional feature is its hydraulically buffered spud carriage, which will permit it to continue to work even in poor weather conditions. Air springs that have been installed under the deck house are also special. They will minimise noise and vibration. ‘It is very important to us that our employees have a pleasant work environment’, says Pieter van Oord.
Sister vessel Athena
Artemis is a sister vessel to Athena, which was delivered at the end of 2011. Van Oord: ‘Building two similar ships will significantly improve the efficiency of our operations.’ Athena is currently being successfully deployed on the Ichthys LNG project in Darwin, Australia.

Research institute Deltares and engineering firm Witteveen en Bos will develop the 2035 Master Plan for the harbour of Beira in Mozambique.
With a population of more than 400,000, Beira is the second largest city in the country. It is located in the estuary of the Pungue River.
Beira will face numerous challenges in the years to come. The master plan sets out an integrated vision for the city, describing how it can respond in the decades to come.
Peter Letitre, the Deltares project leader working on the master plan, describes the challenges: “According to recent studies, Beira is seriously threatened by climate change. The city is just a few metres above sea level, and a clear adaptation strategy will have to be developed to provide enduring protection against the water. Beira also needs to make sure that it has adequate and safe supplies of water (particularly drinking water) in the future.”
In the case of 1 m sea level rise the orange areas of Beira City will have a high risk of flooding, the light blue areas will inundate with water.
“In addition, changes are needed to the drainage and sewage systems to prevent the flooding of the city. There are also developments in the agricultural sector, such as the Beira Agricultural Growth Corridor (BAGC). Those developments will push up the demand for water, and affect the Pungue River and the delta.”
New land and coal transporation
Spatial developments also need to be addressed. Peter Letitre: “The Tete province is home to intensive coal mining. The coal is transported via the Sena railway to the harbour of Beira for transshipment and export. There is a dedicated terminal in the harbour for coal. Preparations are in progress for expanding transshipment and export capacity to approximately 20 million tons a year.”
“The expansion of the coal transport and export activities will have a major impact on the infrastructure and Beira. There is also a demand for the reclamation of new land. They need space for industrial activities, for new and improved housing, and for public facilities.”
Work on the Master Plan will start on 1 February 2013. The plan will be completed in October 2013. Two major follow-up plans will then be developed and final drafting of those plans is scheduled for late 2013. Deltares is also involved here.
To ensure that the plans are actually implemented, financiers will be involved in the follow-up projects in the early stages. Peter Letitre: “The Dutch and Mozambican partners will submit the proposals to international financiers such as the World Bank and the AFDB. But also to public-private parties in Mozambique such as the municipal authority of Beira, the railways, the large mining companies and other investors.”
Deltares is the lead partner in the consortium implementing the project. Alongside Witteveen en Bos, the sub-contractors include Wissing Stedenbouw en Ruimtelijke Vormgeving, Van den Broek Consulting and Niras Mozambique Lda.
The 2035 Master Plan project is part of the Water Mondiaal (Global Water) programme of the Dutch government, This programme aims a long term relationship (10 – 15 years) with Mozambique and four other delta countries, through cooperation on the levels of government, private sector, knowledge development/exchange and NGO’s

“A better understanding of the environmental effects speeds up marine infrastructure projects and reduces the costs”, said director Huib de Vriend on the occasion of the fifth anniversary of the Ecoshape research consortium in Rotterdam on November 15th.
The Ecoshape consortium was formed in 2007 by two leading Dutch dredging companies Van Oord and Boskalis, also involving the research institute Deltares, the universities of Delft and Wageningen, consultancy firms Arcadis and Royal HaskoningDHV and Witteveen+Bos.
The participants want better understanding of coastal ecology for environmental friendly dredging and to be able to use natural processes for beach nourishment and land reclamation. The latter is also known as the ‘building with nature’ concept.
The consortium started with a budget of 30 million euro, half financed by the private sector and half by government. During the lustrum conference its achievements were presented, including seabed landscaping, restoring coastal ecosystems, concentrate nourishment and environmental friendly dredging
More gradual land-water transition
“The programme has so far led to the great number of PhD-studies and pilot projects that have improved the knowledge and experiences with the concept of Building with nature”, explained director Huib de Vriend of Ecoshape on the occasion of the anniversary. “In the Netherlands we have developed a flood defence system with solid dikes that sharply divides land and water. Five years ago we started the Ecoshape research project to be able to learn more about natural coastal processes and environmental conditions to be able to create gradual land-water transition.”
Eco-friendly dredging near coral reefs
At the anniversary conference Ray Masini, manager marine ecosystems of Australia’s national Environmental Protection Authority, spoke about the importance of environmental friendly dredging. “Within the dredging sector the hydrological models are well developed, but not so the transportation models of dredge plumes, and accordingly little is known of the environmental impacts at the start of a dredging project. As a result the permits are based on a worst case scenario and include extensive monitoring requirements ”.
With its many coral reef this poses a great problem to the Australian marine infrastructural projects. “With a better understanding of the ecology and reliable models, we know what to expect. This enables us to learn in the process of the project and adjust the activities where necessary. The great advantage is that the monitoring requirements in the permit can be reduced ”, told Masini.
Less project delays
Frank Verhoeven, founding father of the Ecoshape consortium and currently board member of Boaskalis, spoke about the long lead time of dredging projects close to vulnerable coastal areas. “Last month a dredging project in the harbor of Hamburg was put on hold by court because of concern of its environmental impact.” Verhoeven criticized the poorly scientific based environmental impact studies. “Hopefully we will be able to improve the environmental standards so there will be less project delays.”
More fish inside selective dredged sand pit
“For the continuation of marine infrastructure projects we have to improve our environmental skills”, said Verhoeven. As a successful achievement by the Ecoshape consortium he mentioned the ‘seabed landscaping’ of sand pits. “As part of the c construction of the Maasvlakte 2-project we did a pilot with selective dredging and landscaped the 20 m deep extraction pits with artificial sand ridges. Inside this landscaped pit we found five time more fish, and more species, than outside it”, said Verhoeven.
Sand motor running
The best known pilot project conducted by Ecoshape is the ‘Sand motor’ along the Dutch coast near The Hague. The innovative beach nourishment project is the best example of the ‘building with nature’ concept. By concentrated beach nourishment an artificial peninsula had been created. Wind, waves and tide are now gradually redistributing the sand of this artificial peninsula along the coast causing less disturbance of the local ecosystem compared to classic nourishment.
This video shows the construction and monitoring of the Sand motor.
More international pilot projects
Director Huib de Vriend of Ecoshape showed enthusiastic about the interdisciplinary cooperation between civil engineers and ecologists. “Many ideas have now been picked up worldwide”, said De Vriend. An new research programme is currently being developed for the next five years. “We are looking for more international participation to start pilot projects on non-sandy coasts”, concluded De Vriend.
At the conference the book ‘Building with nature – Thinking, acting and interacting differently’ was presented describing the achievement of the Ecoshape research project.
The book can be downloaded – as a pdf-file, 9mB – from the website of Ecoshape
The first version of the ‘Building with Nature Guideline’ has been published and an editorial board controls a WIKI on the guideline.

Damen delivered a floating booster station to a Chinese contractor working on a Middle Eastern job. The design of the containerized booster and the pontoons is based on maximizing the versatility of the complete unit, yet keeping transport practical and affordable.
The booster station, type BS750, is a fully containerized diesel driven unit. It houses a Damen dredge pump, type BP7570MD, and its 1.825 kW Caterpillar drive. The dredge pump has replaceable Ni-hard 4 wear parts, and is fitted out with a mechanical shaft seal, not requiring grease nor gland water.
The booster works on a Ø 750 mm suction and discharge pipe line. The 40’ container is fitted out with large doors and hatches facilitating service and maintenance. Its most remarkable features are the remote control system, as well as the possibility to use either air cooling or water cooling – making the booster a versatile tool.
The booster is placed on modular pontoons. These multi-functional pontoons can be used as floating units when coupled, or can be used individually as for instance fuel tanks. As the pontoons are provided with an official Container Certificate, they can be shipped anywhere by any means of transport, severely cutting shipping costs and transit times.
The pontoons have been built under LRS Class and have the international notation for Work at Sea. The pontoons have here been designed in a fully self supporting configuration, with fuel storage, drink water and black water storage facilities.
The pontoon is moored using 4 anchors. On the pontoons day and night accommodation containers, work and navigation lights are placed, and safety provisions have been made.
Shipped to Saudi Arabia
The complete floating booster unit will be delivered to China Harbour Arabia Engineering Company, a subsidiary of the important Chinese contractor CCCC Guangzhou Dredging. The unit is shipped to Damman, Saoedi Arabia, where it will join a CHAEC cutter suction dredger working on a port expansion project.
The booster adds a major discharge distance to the current dredger, and it will be remote controlled by the dredge master. Hence the dredge master has a continuous and full control of the entire dredging process, enabling him to maximize efficiency.
Field service assistance
The floating booster unit will arrive at Damman port early November, where Damen field service engineers will assist at its the commissioning and start up. The local crew including the dredge operators will be trained in the use as well as the maintenance of the booster.
As the delivery includes wear parts, spare parts, consumables and tools, the booster will have an excellent start. During the project, the crew will be supported by the local Damen Service representative.
IHC Merwede has launched a new budget range of small hopper dredgers under the name of Easydredge. This is in response to the increasing global demand for smaller dredgers.
The Easydredge series bridges the gap between the existing line-up of IHC Beagle standard hopper dredgers and the standard IHC Beaver cutter suction dredgers.
Three sizes, option packages
Available in three sizes (Easydredge 1300, 2300 and 3300), the new vessels are tailor-made using option packages and can provide a solution for any situation. The Easydredge can be used optimally for maintenance dredging, land reclamation, and the extraction of sand and gravel at sea.
The option packages can also be added later to the ship, making it a highly flexible concept. The vessels are produced using the IHC Merwede network of partner sites or on a local-for-locaol basis.
Reduced fuel consumption
The Easydredge range incorporates the latest technology and engines to ensure green propulsion and durability. This reduces fuel consumption and will help the dredging market to meet increasingly stringent environmental regulations. The Easydredge vessels already comply with the requested requiredments for 2016 (Tier 4) and are suitable for ‘unrestricted navigation’.
Full range of dredgers
Bram Roelse, Director of the IHC Merwede Dredging Division, says: “The Easydredge concept underlines IHC Merwede’s reputation as ‘the technology innovator’. With this new series, IHC Merwede broadens its range of dredgers with an extremely efficient solution and provides a complete range, from the smallest IHC Beaver to the largest hopper dredger.”
The Easydredge vessels can been seen on the IHC Merwede stand (hall B4, EG 201) during the biennial international trade fair for Shipbuilding, Machinery & Marine Technology SMM exhibition in Hamburg, Germany from 4 to 7 September.
This press release was originally published on the website of IHC Merwede.
Royal Boskalis Westminster N.V. (Boskalis) has acquired a contract with port operator Jawaharlal Nehru Port Trust (JNPT) for deepening and widening the port and access channel of JNPT in Mumbai, India.
The contract has a total value of approximately EUR 175 million. The dredging work will commence in September 2012 and is expected to take two years to complete.
Jumbo sized hopper and cutter suction dredgers
The expansion comprises the deepening and widening of the 33.5 kilometers’ long access channel, the port basins and turning basins. In total, approximately 67 million cubic meters of sand, silt, clay and rock will be removed. For this project, a jumbo and medium sized trailing suction hopper dredgers will be used in combination with a jumbo cutter suction dredger and a large backhoe.
Largest container port of India
Jawaharlal Nehru Port is the largest container port in the country with an annual handling capacity of 4.3 million TEU. By deepening the port from the current 11.5 meters to over 14 meters, it will be possible to receive larger types of container vessels and as a result, according to the port operator, the annual capacity will increase to approximately 10 million TEU.
Responding to demand of global trade
The Boskalis strategy is designed to benefit from the key macro-economic drivers that fuel global demand in our selected markets: global trade, increasing energy consumption, population growth and the challenges of changing climate conditions. This project is driven by the demand for global trade.
