GERMAN CONTRACTS FOR BOSKALIS
Holland’s Boskalis recently secured three contracts for coastal protection and port maintenance activities in Germany. These dredging contracts carry a combined value of €45m and will all commence in the coming months.
The first contract was awarded by Germany Waterways and Shipping Office (WSA) WeserJade-Nordsee to upgrade the existing coastal defence on the island of Wangerooge to provide flood protection to the island’s residents. This project will be executed with a local German partner and involves the reinforcement of the groins and revetment for which 200,000 tonnes of rock will be used. In addition to a backhoe dredger a number of split barges will be deployed. Construction works will commence in November 2020 and are expected to be completed late 2021.
Boskalis also won a contract award from WSA Weser-Jade-Nordsee for maintaining a 90-kmslong section of the shipping fairway of the Weser river between Nordenham and Bremerhaven. Under a two-year maintenance contract Boskalis will dredge a total quantity of around 14m m3 of sand and silt, which will be deposited at designated locations along the river. Boskalis will deploy a medium-sized TSHD to carry out the dredging work that will start early 2021 and last until the end of 2022.
The third contract that Boskalis secured was awarded by Niedersachsen Ports for the maintenance of the port of Emden, one of the largest German North Sea ports. Starting November 1st 2020, Boskalis will maintain the port at the required depth by dredging an annual volume of around 2.7m m3 of sand and silt with a trailing suction hopper dredger for two consecutive years.
The project on the island of Wangerooge is aimed at combating the consequences of extreme weather related to climate change. The activities in the Weser River and the port of Emden are largely driven by the need to maintain the accessibility of ports to accommodate global seaborne trade. With its groundbreaking activities and unique expertise, Boskalis is exceptionally positioned to play a significant societal role in creating and protecting welfare and advancing the energy transition.

JAN DE NUL AND BESIX AWARDED THE EXPANSION OF THE PORT OF FUJAIRAH IN DIBBA
BESIX and Jan De Nul Group are assisting with the expansion of the Port of Fujairah (PoF) in Dibba, the second largest city of the Emirate of Fujairah in the UAE, located along the Gulf of Oman.
The works for the Dibba Bulk Handling Terminal Project were awarded to the consortium of Six Construct, BESIX’s entity in the Middle East, and Jan De Nul Group by the PoF, one of the world’s
Dibba Bulk Handling Terminal
key oil storage centres and the second-largest ship-bunkering hub in the world.
The design-and-build contract comprises dredging the navigation channel, port basin, reclamation and shore protection, as well as constructing breakwaters, a 765 m long quay wall, foundations for ship loader rails, port infrastructure and creating utilities and aids to navigation. The fishing harbour will be relocated in the process.
The expansion plans are part of PoF’s strategy to increase the port’s bulk handling capacity and operational efficiency, as well as improve the quality of its service, which is considered among the best in the world.
The consortium’s approach to optimise the design by providing ‘value engineering’, along with the newly-established Central Marine Support department, presented a strong, competitive solution to the client.
Yasser Laroussi Ben Asker, Operations Manager Marine Works Middle East at Six Construct said, Rijkswaterstaat, the executive agency of the Dutch Ministry of Infrastructure and Water Management, has awarded the final phase of the enlargement of the Twente canals to a consortium of Van Oord - Hakkers - Beens. The work will start in the spring of 2021 and will last until the end of December 2022.
By enlarging the waterway, the ports of Almelo, Hengelo and Enschede will be more easily accessible and larger vessels will be able to sail through more safely and smoothly. This will boost the regional economy and make water transport even more attractive. The Van Oord - Hakkers - Beens consortium will be responsible for enlarging the canal, replacing the current sheet piling over a length of 35 kms and applying a self-sealing layer at the bottom of the canal. The consortium will also create 13 kms of naturefriendly banks. “Six Construct is very pleased and honoured to partner with the Port of Fujairah, as part of our decades-long history in the Emirate. The history of Six Construct and the port of Fujairah are very connected. BESIX’s entity in the Middle East helped on several occasions to extend the port infrastructure. We share the same values in aspiring to create long-term partnerships to support the Emirate’s development goals, and we are investing in a long and prosperous relationship.”
Stefan Moens, Area Manager Middle East at Jan De Nul Group added, “We build on many years of experience in the UAE and this award confirms the PoF’s satisfaction with our previous port expansion projects executed in the region. We are very proud to be appointed as a trusted partner for the delivery of these works in consortium with BESIX - another company with Belgian roots.”
The contract is valued at AED371m (€90.4m). Work will be carried out over the coming 19
VAN OORD WINS NEW CONTRACTS IN HOLLAND, UK AND TAIWAN
months. “We look forward to working with the consortium on the second phase of the enlargement of the Twente canals. We are pleased to use our ingenuity to contribute to Rijkswaterstaat’s ambition to reduce road freight traffic,” said Richard Brouwer, Director Netherlands at Van Oord
Rijkswaterstaat has also awarded Jan de Nul the contract to design and to carry out the removal of silt from the Averijhaven depot in IJmuiden. After the removal of the contaminated silt, the area will be developed into an energy port. The contract has a value of €18m and preparations will start in the spring of 2021.
The Averijhaven is located adjacent to the shipping route in the direction of the sea lock at IJmuiden (the Noorderbuiten Canal) and the Tata Steel site. For a long time, it served as a dredging depot for Rijkswaterstaat, but was no
longer used in recent years. With the removal of the silt, the Averijhaven is being prepared for its new role as an energy port. This new port will be an important operating base for the construction and maintenance of offshore wind farms that will be built in the years ahead.
For this remediation project, Van Oord will be deploying a cutter suction dredger. The cutter suction dredger will transport the silt from the depot via a fully enclosed system to a transport vessel, probably a large trailing suction hopper dredger. This vessel will then transport the material to the Slufter depot. During the work, the stability of the ring dike will be monitored continuously by means of a measuring system.
Van Oord has also been contracted to dredge the water intake basin of the Taiwanese Da Tan power plant. The cutter suction dredger HAM 218 and the TSHD HAM 318 will join forces on this project, which will kick off early 2021.
Driven by the growing demand for energy in Taiwan, the Da Tan power plant is currently being expanded by Hwa Chi Construction Co. Van Oord’s HAM 218 will deepen the existing water intake basin to increase its capacity to take in cooling water.
“Van Oord came up with the smartest and most optimal solution to deepen the shallow and narrow inflow bay within an extremely short time frame - proof of its marine ingenuity and many years of experience. We are looking forward to successfully realising this project together,” said Mr Tsai, Chairman at Hwa Chi Construction Co.
The TSHD HAM 318 will transport the dredged material from Da Tan, located on Taiwan’s northwest coast, to Taipei. It will be pumped ashore to reclaim a new port area, allowing the port in Taiwan’s capital to expand. Van Oord’s scope will be completed by mid-2021.
Guus de Vries, Area Director at Van Oord said, “We are pleased that Hwa Chi Construction contracted Van Oord for these dredging works. We worked together on a number of Taiwanese projects before, including Kaohsiung’s port expansion. Our mutual trust was key in receiving this award, without having any physical meetings due to COVID-19.”
Van Oord has been active in Taiwan for many years. In 2017, it received the Golden Quality award for the successful execution of Kaohsiung’s port expansion. These reclamation works were completed eight months ahead of schedule, enabling Taiwan’s largest port to grow.
Meanwhile, Aberdeen Harbour Board has awarded two contracts for rock removal and revetment work for the Aberdeen South Harbour expansion project to Van Oord. Van Oord’s backhoe Razende Bol joined backhoe Goliath at the project site in Scotland.
The Harbour expansion project is the largest marine infrastructure project underway in the United Kingdom. After completion it will open
significant opportunities for the region, in both new and existing international markets.
Michelle Handforth, Chief Executive of Aberdeen Harbour Board, said, “We are pleased to announce the award of these contracts to Van Oord, who have been heavily involved in the South Harbour expansion project for several years. It is an amazing sight to see one of the world’s largest dredgers working on our project.”
The profile work for the harbour basin and the shore protection is expected to be completed in time for the coming winter. Part of the work will be executed by the Goliath, which has been deployed on large-scale port expansion projects around the world. The Razende Bol is a wellknown guest in the United Kingdom’s coastal waters. The backhoe has worked on several outfall projects over the years, recently at Withernsea, fifty kilometres north of Hull. The backhoes are accompanied by three split hopper barges.
“The expansion of Aberdeen Harbour is a significant project for Scotland, and we are proud to continue our involvement, having been part of the project since 2017. We look forward to working towards the completion of the expansion, utilising our world-class equipment, international experience and Marine ingenuity,” added Joost van Duinen, Van Oord’s Project Manager.
