Boskalis has secured three contracts for coastal protection and port maintenance activities in Germany. The contracts, worth EUR 45 million, will all begin in the coming months.

The first contract was awarded by the German Waterways and Shipping Office WSA Weser-Jade-Nordsee. The work includes upgrade on the existing coastal defense on the island of Wangerooge.

This project will be executed with a local German partner and involves the reinforcement of the groins and revetment for which 200,000 tons of rock will be used.

In addition to a backhoe dredger a number of split barges will be deployed.

Also, the construction will start in November 2020 and are expected to be completed late 2021.

Furthermore, Boskalis received a contract award from WSA Weser-Jade-Nordsee. This job includes maintaining a 90-kilometer-long 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 14 million cubic meters of sand and silt, which will be deposited at designated locations along the river.

For this work, Boskalis will deploy a medium-sized trailing suction hopper dredger to carry out the dredging work.

The project will start early 2021 and last until the end of 2022.

Finally, the third contract that Boskalis secured was awarded by Niedersachsen Ports for the maintenance of the Port of Emden.

Starting 1 November 2020, Boskalis will maintain the port at the required depth by dredging an annual volume of around 2.7 million cubic meters of sand and silt with a trailing suction hopper dredger for two consecutive years.

The U.S. Army Corps of Engineers will begin maintenance dredging in the Federal navigation channel at Keystone Harbor in Seattle this week.

The contractor, American Construction, is set to start dredging works today and continue for approximately nine weeks.  

The project’s goal is to dredge roughly 50,000 cubic yards and place the material along the shoreline on the east side of the harbor. 

Also, dredging will only occur at night between 9:10 p.m. to 6:45 a.m. to accommodate daytime ferry vessel traffic. 

Furthermore, dredged material will be offloaded into the temporary stockpile area. Finally, it will be transported to the upland beach nourishment placement site during daylight hours.

“During the dredging, a gate for boat traffic will be temporarily installed by American Construction. If a boater needs to launch a boat, the gate will be opened by American Construction,” said USACE.

Following the successful WODCON XXII conference, organized by the Chinese chapter of the Eastern Dredging Association (EADA) in Shanghai last April, the host of the next WODCON, CEDA, announced the details for the next congress in the series.

WODCON XXIII will take place from 16th-20th May 2022, at the Tivoli Congress Centre, Copenhagen, Denmark, and the theme will be ‘Dredging is changing’.

Not only is dredging, as an activity, always primarily targeted to modify the environment, it is also changing in terms of the positive impacts it can have on the natural and socio-economic environment.

Johan Pennekamp, Chair of the WODCON XXIII Organizing Committee, explained the thinking behind the theme by saying, “Apart from stating that our way of dredging is changing – just think: advances in dredging technology, novel solutions for adaptation to climate change, nature-based approaches, circular design, benefits/value for all stakeholders, corporate social responsibility, sustainable approach – these three words actually have a more philosophical depth too.”

He added, “Dredging always means changing the environment whether it is capital dredging or even maintenance. Dredging always aims to create a new or improved situation and this aspect is quite often not recognized or appreciated!”

The words of the Organizing Committee Chair were supported and illustrated by a spectacular video which can now be downloaded from the official website of WODCON XXIII.

CEDA also announced the first committed sponsor to the congress, Rohde Nielsen, inviting members of the worldwide dredging community to demonstrate their support to the single most important event where the worldwide dredging community meets.

The Department of Transport, Western Australia, recently awarded a major long-term contract to improve the efficiency and reduce the frequency of dredging required at different coastal locations each year.

Under the $13.35 million contract, BMT Commercial Australia Pty Ltd will provide their professional consultancy services. The aim of this contract is to support DoT’s annual dredging program.

The program, worth around $7.9m, provides maintenance dredging, sand bypassing and coastal management at more than 30 sites. Included in the program are ports at Wyndham and Derby at varying frequencies.

Nevertheless, the contract secures up to 32 jobs including the creation of 12 new positions in a specialised field.

“The aim of the contract is to achieve long term solution-based outcomes and efficiencies in the program,” DoT Maritime Executive Director Steve Jenkins said.

“DoT continues its commitment to an efficient, sustainable dredging program that limits the impact to the public,” Mr Jenkins added.

“The contract helps DoT deliver the program at minimal cost and with maximum benefit to the comunity,” Mr Jenkins concluded.

Dredging work on the Intracoastal Waterway in the vicinity of St. Lucie Inlet and Jupiter Inlet will start today.

The project will include the dredging of approximately 48,000 cubic yards of material from the vicinity of the St. Lucie Inlet with placement within the St. Lucie Impoundment Basin, and approximately 95,000 cubic yards dredged from the vicinity of Jupiter Inlet with placement on the beach south of the Jupiter Inlet.

The dredging is anticipated to begin in the vicinity of the Crossroads area in St. Lucie Inlet in Martin County. Further, these works will be followed by operations in the vicinity of Jupiter Inlet in Palm Beach County. 

Also, maintenance dredging along the IWW is expected to be complete by February 28, 2021.

Beach placement activity will not begin until November 1, 2020, and will be continuous, 24 hours a day, seven days a week, until completion.

Dredge material placement will be conducted in compliance with the applicable Florida DEP permit, and the awarded plans and specifications.

Finally, the project is being executed under a $2.7m maintenance dredging contract that the USACE Jacksonville District awarded as a small business set aside contract to Coastal Dredging Company, Inc., of Hammond, La., July 27, 2020.

Tonnes of sand will be placed onto Holloways Beach this week to help mitigate foreshore erosion, reports the Cairns Regional Council.

This coastal erosion has been exacerbated by recent high winds and associated tidal conditions.

As part of an urgent response, 600 tonnes of sand will be brought in soon and placed at the worst hit locations.

Division 8 Councillor, Rhonda Coghlan, said: “Council is very much aware of the situation and is working to protect the foreshore.”

“Erosion remains a concern at Holloways Beach and it is hoped the adoption of the latest strategy, which included the installation of two 30-metre groynes, will provide the necessary protection to the foreshore.”

Council adopted an erosion management strategy last September to undertake minor sand nourishment, install two rock groynes and finally undertake large scale sand nourishment works.

“Combating erosion along a beach foreshore is challenging; a few years back Council spent over $600,000 on sand nourishment at Holloways Beach, only to have this sand washed away in weeks.

“That is why the building and installation of the groynes prior to any major sand nourishment was an imperative.

“Now that they are in place, you can see the groynes are doing their job and holding the sand on the southern end of the beach.”

A contract for the delivery of 30,000 cubic meters of sand will be put to Council at the end of this month.

“I would expect those major sand nourishment works will take place before the end of the year, weather permitting.”

“On top of that, Council will also consider installing more groynes towards the north end of the beach.”

Council will also be temporarily removing a commemorative bench. This area is in danger of being damaged due to the recent erosion events.

As part of San Antonio Port’s expansion plans, a cross-organisational team has presented its final report assessing the structural stability and port operability of the proposed new outer breakwater in Chile.

The report was the result of more than a year’s partnership between HR Wallingford and Instituto Nacional de Hidráulica Chile (INH).

Together they built and tested models representing a huge area – the 3.9km breakwater, a sub-marine canyon and the harbour.

The main objective of this study is to assess the structural stability of a breakwater to shelter the terminals.

In terms of area replicated, it was one of the largest ever models by HR Wallingford, and in terms of time, it was one of its longest.

The results of all the assessments were passed on to the designer, SENER, which is using them to optimise the structural design before construction starts.

Van Oord recently released a video about the land reclamation project for Mexico’s new oil refinery in Dos Bocas, Tabasco.

In just ten months time, Van Oord successfully completed this mega project, creating 600 hectares of new land.

This was possible thanks to the company’s cutter suction dredger Athena and trailing suction hopper dredger Lelystad.

By combining the strengths of CSD Athena and TSHD Lelystad, Van Oord dredged a total of 12 million cubic metres of sand for this land reclamation project.

The project also included 400 hectares of dynamic compaction and 6 million cubic meters of dry earth movement.
