The HS 8030 HD belongs to the 30-ton class of machineIn order to save weight and also to ensure stable positioning, WSA decided to install the machine on a fixed base column.Due to the low installation height of the machine the vessel’s center of gravity is improved and therefore provides for easier operation. The Waterways and Shipping Office has purchased a total of five machines type HS 8030 HD, all of which will operate on similar vessels. Positive experience with the machine and local service were important factors in the decision to purchase from Liebherr. The vessel is predestined for operation in shallow waters as it has a draught of about 1.1 m. In general it operates in water depths up to a maximum of 10 m. Grabs with capacities of either 1 m³ or 2 m³ can be fitted to the HS 8030 HD, depending

on requirements. For work with large stones an orange peel grab (polyp) is occasionally used. “The Upper Rhine is still a rough water. In July the water depth is approximately 4.5 m, but when depths increase to 7.5 m the water flows at high speeds and is hard to negotiate.” The grab dredge “Zander,” which belongs to the Waterways and Shipping Office Mannheim (WSA), has recently returned to operation following a period of renovation. With a width of 8.6 m and a length of approximately 30 m it is ideally suited for the maintenance of the waterway beds and locks, as well as the upkeep of safety embankments. Rock material and gravel can be effortlessly removed or precisely positioned by the on-board Liebherr duty cycle crawler crane type HS 8030 HD. “There’s always gravel in the Rhine - if you are quiet you can permanently hear the gravel hitting the ship’s propeller,” says the machine operator Herr Horn. In that case the WSA will never run out of work. Within a short period new material is washed up.

IntroductionConventional methods for addressing beach erosion are often just temporary measures that fail to achieve long-term satisfactory results. The most common beach restoration approach currently used is dredging, in which a depleted beach is “nourished” by sand removed from another location onshore or off-shore. Other practices utilize man made structures composed of wood, concrete, rocks, or sandbags that “harden” the beach, redirect wave action and restrict sand movement to specific areas. These measures are often costly, dangerous to beach users, and unsightly. In addition to intensifying erosion, these methods can create new environmental issues such as disrupting biotic life or altering the structure of the beach habitat. Most importantly, they are ineffective because they often fail to address the major causes of beach erosion: sand dune destruction, long-shore drift disruption and saltwater intrusion. An overlooked and underestimated contributor to coastal erosion is the change in the characteristics of sand brought through beach nourishment. Imported beach sand is non-cohesive and is easily eroded and suspended in water, even under moderate wave action. The imported sand can have other detrimental effects, such as impoverishing biotic diversity. Stable sand dunes play a crucial role in protecting the coastline. They act as a buffer against damage from waves during storms, helping protect the back-shore from salt-water intrusion. This critical sand barrier fosters the development of complex plant communities in the areas protected from salt-water intrusion, damaging winds and sea sprays. The dunes also serve as a sand reservoir to replenish and help maintain a sustainable beach during erosion cycles. Current areas of research in beach erosion include the correlation between dune topography and the fresh water lens that prevents saltwater intrusion and the correlation between salt water intrusion and beach erosion. Research being conducted by the Center of Water Supply Studies at the Texas A&M University in Corpus Christi, indicates that the fresh water lens under the Mustang Island, a barrier island, was more extensive below the zone with large dunes than the lens below the zone with degraded dunes. Research being conducted on saltwater intrusion in the coastal aquifer of the Southern Po Plain in Italy indicates that eroded coastal areas are associated with freshwater heads that are not high enough to counteract saltwater intrusion in agreement with the Ghyben-Herzberg principle. In areas that had a relatively pristine freshwater aquifer thanks to a higher topography of continuous dunes that allows for an average height of the water table of two m above sea level, saltwater intrusion was prevented. There is also research conducted at Qatar University that indicates a “significant positive relationship between the groundwater salinity problem and coastal erosion” at the Al-Arish area in North Sinai, Egypt. Eroded sections of the coastline were associated with saltwater intrusion and the non-eroded sections

did not suffer from saltwater intrusion. It is increasingly clear that the acceleration and severity of beach erosion over the last sixty years is due in a large part to the causes described above, in addition to sea level rise. Although serious efforts have been made to rebuild dunes, reestablish long-shore drift and minimize windblown erosion, no measures have been taken to enhance sand retention on natural or nourished beaches. The natural chemical and physical properties of sand are critical to the health of a beach because they provide a means of interacting with and retaining fresh water. The ability to interact with fresh water is absolutely essential to the beach environment because freshwater allows life to flourish, disperses nutrients, provides cohesion within the beach, and forms a lens that protects against the coastal intrusion of salt water. A healthy beach system has several sources of freshwater, including the coastal aquifer behind it, rain, condensation and streams. One potential solution to enhancing the physical and biological properties of sand is the use of natural biopolymers. The impact of natural biopolymers on sediment cohesion has been actively studied. The studies have demonstrated that extracellular organic secretions from microorganisms and microphytobenthos can coat sediment clasts, act as a mucilage glue, and increase the cohesive nature of the sediment. The organic exudates (proteins and carbohydrates) form biofilms on the surface of sand grains and enhance the cohesion of sediment by forming tiny aggregates that grow larger as the activity from microorganisms and microphytobenthos continues. The secretions increase critical erosion velocity of intertidal sediment and result in higher erosion thresholds throughout periods of desiccation.

Case StudyProprietary protein polysaccharide biopolymer formulations (PPBs) have been developed by Dr. Dahmani. The product formulations are composed of polysaccharides and protein extracts that are generally Recognized as Safe (GRAS) by the FDA. They are designed based on the characteristics of the site sand characteristics and water chemistry. When a solution of PPBs is placed in sand, PPBs abiotically coat the surfaces, thereby enhancing shear strength and cohesion. One of the PPB formulations, Sand First, was tested by Marcost SA de CV of Mexico for a beach erosion mitigation application on a re-nourished beach in Progreso in Mexico’s Yucatan peninsula (Figure 1). The Sand First PPB solution was placed approximately every two weeks for five months in shallow trenches in the intertidal zone and the treatment results were monitored over a one-year period. The PPB solution was also used to minimize wind-blown erosion and stabilize sand dunes. Dry beach profiles and bathymetric profiles were obtained, and sand accretion/erosion were monitored for the PPB-treated beach section (85 m) and compared to two similar untreated beach sections (controls) located on both sides of the PPB-treated beach. Beach profiles were measured monthly for a year to assess the effectiveness of the PPB treatment in controlling beach erosion. The results indicated that the erosion/accretion rate in the treated section was +0.06 m3/m indicating accretion, whereas in non-treated control sections, the rate was -4.04 m3/m, indicating erosion. The findings indicate that using PPBs is a promising eco-friendly method for enhancing nourished beach retention by enhancing sand cohesion. One should note that the intent of the PPB treatment is to enhance sand cohesion sufficiently to minimize offshore transport of sand. During erosion cycles, sand from the dry beach area was transported to the near shore area and remained an available sand source during accretion cycles. Therefore, it is recommended that beach erosion mitigation methods include sand treatment in order to reduce the frequency of re-nourishment efforts. The benefits are three-fold: enhanced sand retention, minimization of the negative biotic impact of beach erosion, and reduction in the overall cost of beach erosion mitigation.

Fraser River has been contracted by Public Works and Government Services Canada to carry out the cleanup of the largest Canadian contaminated site on the Great Lakes. The location is Randle Reef in Hamilton Harbor, the western tip of Lake Ontario. The site is approximately 60 hectares ( ha ) in size, and contains some 695.000 m3 of contaminated sediment Fraser River’s scope of work on the clean-up includes dredging of a half a million cubic m of contaminated sediment, disposal of the sediment in an engineered containment facility, as well as the downstream water treatment. To ensure all contaminates are dredged and to avoid over dredging of the underlying clean soils high accuracy dredging is required. As such Fraser River is currently taking delivery of a project specific cutter suction dredge. Prior to the arrival of this dredge on-site Fraser River has procured a DOP350 to conduct dredging within close vicinity to infrastructure including sheet pile walls and docks.

Dredging Contractors of America ( DCA )Applauds President Trump & Congress for their Bipartisan Work on Water and Energy Legislation

On Friday, September 21, 2018, President Donald Trump signed into law the Energy and Water, Legislative Branch, and Military Construction and Veterans Affairs Appropriations Act, a three-part package called a “minibus” at a signing ceremony at VA Southern Nevada Healthcare System in Las Vegas, Nevada ( NV ). The legislation accounts for dredging activities in harbors and channels, important infrastructure projects and beach and coastal restoration. The $147B package includes a 2.4% increase in military construction spending and an 11% funding increase for the US Army Corps of Engineers’ Civil Works Program. The U.S. Senate approved the measure 92-5, while the U.S. House passed it 377-20. The total funding for the Civil Works program is $6.9985B, approximately $2.2B above previous levels. In addition, legislative measures include significant increases in funding for construction of shoreline protection, beneficial use of dredge material, national coastal mapping and coastal inlet research. The new law does not call for the reorganization of the Army Corps of Engineers. This is the first time in over 10 years that the President has signed three spending bills into law before the beginning of the fiscal year. Indeed, the Army Corps will have its budget at the start of the fiscal year (October 1st), instead of waiting for continuing resolutions throughout a budget cycle to keep the agency funded. “This is great bipartisan work by Congress and the Administration. We thank President Trump for signing the supporting infra-structure measures into law,” said William P. Doyle, CEO and Executive Director of the Dredging Contractors of America. “It all start with dredging—and America’s going to work building America,” Doyle concluded.

The size of the DOP was based on the estimated production capability of the downstream water treatment plant. The balance of dredge slurry production and effluent outflow from the engineered containment facility into the water treatment plant is of critical importance to the success of this project. The job at Randle Reef can be described best as a huge clean-up action. Hamilton Harbor is listed under the Canada and United States Great Lakes water quality agreement as an area of concern. Areas of concern are locations on the Great Lakes

are where water quality and ecosystem health have been severally degraded by local development use or other activities. One of the last obstacles to restoring Hamilton Harbor and removing it from the list of areas of concern is the cleanup of contaminated sediments at Randle Reef located at the western end of Hamilton Harbor.

Hamilton Harbor is the largest Canadian port on the great lakes and home to one of the largest concentrations of heavy industry in Canada including steel production. The contamination at Randle Reef is a result of multiple sources over a period of more than 150 years including coal gasification, petroleum refining, steel production, municipal waste, sewage effluent, and overland drainage.

Randle Reef is contaminated with Polycyclic Aromatic Hydrocarbons (PAHs) and heavy metals. The PAHs are present in very high concen-trations and are of greatest concern as because they are known to be persistent, toxic, and carcinogenic. PAHs contribute to restrictions on fish and wildlife consumption, fish and wildlife deformity, and repro-ductive problems in Hamilton Harbor. Cleaning up Randle Reef is one of the last vital steps remaining to remediate Hamilton Harbor. The project will reduce the amount and spread of contaminants through the Harbor, significantly improving water quality and fish and wildlife habitat. The Harbor will also experi-ence economic and social benefits: improved shipping and port facilities, increased recreational opportunities and the promotion of the Harbor community as a clean and progressive place to live and work.

Texas Gulf Terminals Inc has submitted plans to construct, own and operate a deepwater port terminal in the Gulf of Mexico to export crude oil :• Site located ~12.7 nautical miles off the coast of North Padre Island • Flow rates of up to 60,000 barrels per hour • Approximately 8 Very Large Crude Carriers (VLCCs) vessels loaded per month • VLCC expected to take 48 hours to load, including approach, mooring, cargo transfer and vessel departure • The single point mooring (SPM) buoy system would be positioned in water depths of ~93 feet • SPM would be located in BOEM lease block number 823 • Project would include SPM buoy system, a valve station, a booster station, and OSTF and 2 30” pipelines connecting the components In our day to day business, we see the enormous economic opportunity presented by U.S. oil exports, and we also see the intense need for expanded export capacity to deliver U.S. oil to the market. This project will allow very large crude carriers (VLCCs) and other supertankers to load cargo safely, directly and fully via an SPM in the Gulf of Mexico, building U.S. export capacity and creating jobs in Texas. U.S. crude oil exports are expected to surge in the next five years, increasing from 1.1M barrels per day (MMBPD) to 4.8 MMBPD by 2022. The region needs additional infrastructure to capitalize on this growth. Almost 75 percent of this increase will take place in the Permian and Eagle Ford which produce light, low sulfur crude oil. Texas Gulf Terminals will handle only about 10 percent of the expected growth in U.S. oil production. It will complement, not replace, exports from the Port of Corpus Christi. TGTP will allow very large crude carriers (VLCCs) and other supertankers to load cargo safely, directly and fully via a single-point mooring buoy system (SPM) in the Gulf of Mexico, building U.S. export capacity. Expanded export capacity is necessary because U.S. refineries are either designed to process heavy, high sulfur crude oil or at maximum processing capacity on light, low sulfur crude oil. The incremental light, low sulfur crude oil will need to be exported to support U.S. economic growth. The Texas Gulf Terminals infrastructure will include a new onshore terminal which will be fed via pipeline(s). The

project will be funded by Trafigura. It’ll be a significant investment. Timing is tbd as we have just begun the permitting process under the DWPA. During peak construction, over 700 construction workers will be employed. Once the project is

Texas Gulf Terminals Project


in operation it will create approximately 50 full-time jobs and

hundreds of jobs related to the ongoing operations around the project. The Texas Gulf Terminals Project is the latest of a series of long-term investments that Trafigura has made in communities across the U.S., including a nearly US$1B in investment in the premier marine export terminal and condensate splitter in Corpus Christi, Texas (Buckeye) and the construction of the Burnside Bulk Storage Terminal in Darrow, Louisiana, which rebuilt a site from the mid-1950s into a state-of-the-art bulk facility designed to facilitate international exports. TEXAS GULF TERMINALS PROJECTThe U.S. natural gas and oil industry is a critical part of the economy, contributing more than US$ 1.3T and supporting 10.3 M jobs in 2015. As U.S. crude oil production surges, oil exports have also grown, with projections reaching 4.8M barrels per day by 2022. Without new investment, today’s U.S. export infrastructure will be unable accommodate this volume, which will restrict production and slow economic growth. Ve r y L a r g e C r u d e Carriers (VLCCs) are the most economical and efficient way of transporting crude around the world, carrying up to 2M barrels per voyage, however no US inland ports are capable of fully loading a VLCC. Currently, to fully load a VLCC multiple Ship To Ship Transfers (STSs) are performed in lightering zones out at sea.

Xby DNSUnlockerOn July 9, 2018, Texas Gulf Terminals, Inc., owned by Trafigura US Inc., part of privately-held physical trading and logistics comp-any with offices in Houston, Texas, submitted its permit application for a new Project. The Texas Gulf Terminals Project is a new offshore Deep Water Port facility that will allow VLCCs and other t a n k e r s t o l o a d c a rg o safely, directly and fully via a single-point mooring buoy system (SPM). Using SPMs eliminates unnecessary ship traffic in inland ports as well as the “double handling” of the same crude oil, re-ducing the opportunity for spills and emissions each time the crude oil is transferred.

Jan De Nul ProjectsJan De Nul kicks off Changhua OWF projectOnshore cable installation works started

Jan De Nul Group kicked off the activities for the Taiwan Power Company Offshore Windfarm Phase 1 Project – Demonstration. The sod cutting ceremony was held on 25 August 2018 in the presence of the Client Taiwan Power Company, local authorities and the Consortium Jan De Nul-Hitachi. I n a f i r s t p h a s e , t h e consortium executes the onshore cable installation works to connect the existing onshore sub-station to the cable interface near shore. The onshore cables are currently being installed in an underground track of 13 km of duct banks. For these construction works, 2 km of horizontal directional drillings are performed over 13 different locations and 45 prefabricated manholes are installed. Onshore works will take 20 months and are executed by the Taiwanese subcontractor Star Energy Corporation. The connecting submarine cable will be installed in the course of 2020.

Changhua Offshore Wind FarmThe Changhua Offshore Wind Farm contract was awarded to the Consortium Jan De Nul-Hitachi on 30 April 2018. The project entails the manufacturing and installation of 21 5.2MW offshore wind turbines for the Changhua Offshore Wind Farm, off the coast of Fangyuan in Central Western Taiwan. The works also include manufacturing and installation of all equipment as well as operation and maintenance for a period of five years. Jan De Nul Group is responsible for the design, fabrication and installation of the foundations, the installation of the wind turbines, the supply and installation of the cables off- and onshore as well as for the upgrading of the substation. Hitachi Ltd. is in charge of manufacturing, assembly, operation and maintenance (O&M), and other works related to the offshore wind turbines with downwind rotor. Particular feature of the design is that the foundations and wind turbines are designed to withstand cyclonic waves and winds, and earthquake loads. Manufacturing of the wind turbines is planned mainly during 2019 in order to deliver them in early 2020. Test operation of the equipment is targeted to start in the summer of 2020, and the completion is scheduled for the end of December of the same year.

Jan De Nul successfully completes first job with TailleventA new 83 t crane installed on offshore Wikinger substation in Germany Jan De Nul Group has successfully completed the installation of a new 83 t crane on top of the offshore substation of the 350MW Wikinger Offshore Wind Farm in

DEME Group ActivitiesContinued

DEME orders two trailing suction hopper ( TH ) dredges & two split barges ( H )On September 6, 2018 DEME announced its continued fleet investment by adding two trailing suction hopper ( TH ) dredges and two self-propelled split barges ( H ) to the dredging fleet. The new vessels and barges will be built by Royal IHC. The first vessel will be a trailing suction hopper ( TH ) dredge with a hopper volume of 8,300 m³. The new trailing suction hopper has the same innovative design as its sister vessel ‘Scheldt River’ ( Below ) which entered the DEME fleet in 2017.

Since it became part of the fleet the dual fuel hopper ‘Scheldt River’ has operated non-stop on waterways and access channels in Europe. In line with this success, DEME is keen to provide clients with a versatile and highly efficient vessel identical to the ‘Scheldt River’ for a broad range of dredging activities. The second vessel will be a 2,300 m³ trailing suction hopper ( TH ) dredge. With a dead weight of circa 2,800 t and a design draught of only 4.25 m, the compact design ensures high maneuverability and optimized dredging works in shallow waters. This shallow water TH dredge has a very robust design and is easy to operate and maintain. Additionally, two self-propelled split hopper barges are joining the DEME fleet, both with a volume of 3,500 m³. The barges are designed specifically in view of working together with DEME’s larger cutter suction ( CS ) dredges and in particular the ‘Spartacus’, as well as DEME’s backacter ‘Samson’. They are a development of DEME’s proven and successful 2,750 m³ barges ‘Pagadder’ and ‘Sloeber.’ The new trailing suction hopper dredges and barges will enter the fleet in 2020. “This order once again signifies our ongoing commitment to operate the most modern, versatile and environmental friendly fleet,” said Alain Bernard, Director and CEO of DEME. “With our multi-year fleet investment program we are driving new levels of performance and further enhance the capacity of our fleet, providing our clients with flexible solutions for dredging and reclamation projects in various environments.” Dave Vander Heyde, CEO of Royal IHC stated, “IHC is proud that DEME has ordered four highly competitive new vessels. With this order the number of trailing suction hopper dredges in the fleet of DEME, designed and built by IHC adds up to 21. The partnership with DEME has proven to be successful in the past, and we are pleased to continue our partnership with DEME by adding more value and technical capabilities to their advanced fleet.” A number of pioneering vessels recently entered the DEME fleet, including the dual-fuel dredges ‘Minerva’ and ‘Scheldt River’ in 2017, the cable installation vessel ‘Living Stone’ and DP2 jack-up platform ‘Apollo’ in 2018. Currently, DEME has no less than three other innovative vessels under construction: the powerful 44,180 kW cutter suction ( CS ) dredge ‘Spartacus,’ the 15,000 m³ trailing suction hopper ( TH ) dredge ‘Bonny River’ and the giant offshore installation vessel ‘Orion.’


DEME unveils nodule collector pre-prototype ‘Patania II’ On September 21, 2018 DEME subsidiary Global Sea Mineral Resources (GSR), specialized in deep sea harvesting, has unveiled the nodule collector ‘Patania II.’ The pre-protoype is the successor of the tracked soil testing device ‘Patania I’, which was successfully tested during a 2017 expedition in the Central Pacific Ocean. A g a i n s t a b a c k g r o u n d o f a g r o w i n g p o p u l a t i o n a n d a n i n c r e a s i n g scarcity of resources, GSR is developing breakthrough, deep sea mining technologies. The ‘Patania II’ integrates the track design of the first ‘Patania’ prototype with a suction head to collect polymetallic nodules from the seabed. In 2019 the nodule collector will embark on its first expedition in the GSR and BGR (German) exploration areas, involving a test area of 0.1 km2. Back in 2013, the International Seabed Authority granted GSR a 15-year concession to explore 76,728 km2 of seabed in the eastern part of the Clarion Clipperton Zone in the Central Pacific Ocean. During the expedition the vehicle will temporarily store nodules harvested from the seabed in a hopper for data collection, and redeposit them in the test area. GSR will use the test data to validate the performance of the technology and to assess the environmental impact of the test operations. Polymetallic nodules can be found on the seabed in most oceans around the world and contain large quantities of critical raw materials such as nickel, copper, cobalt and manganese. These metals are vital for the urbanization and electrification of our planet as they are key ingredients for stainless steel, batteries, wind turbines and photo-voltaic systems. GSR has teamed up with Ghent University and together they will mon-itor the in-situ environmental impact of the ‘Patania II’, again gathering crucial design data, allowing GSR to further redesign its technology to increase efficiency and minimize its impact. Furthermore, an international consortium of scientists from the EU Joint Programming Initiative for Healthy and Productive Seas and Oceans will provide independent and transparent report-ing of additional environmental measurements. All information regarding the environment will be publicly available. ‘Patania II’ has been developed by GSR in cooperation with the Belgian engineering company De Meyer of Temse, Belgium.

Boskalis Stays BusyBoskalis uses biofuel on Borssele renewable energy project Royal Boskalis Westminster N.V. (Boskalis) announced it will use a biofuel blend on the project to install the export cable to the Borssele offshore wind farm resulting in a more sustainable realization of this renewable energy project. The Borssele Alpha project is being executed on behalf of TenneT and is aimed at connecting the Borssele offshore grid with the Dutch high-voltage grid. During this project Boskalis will run its vessels on a biofuel blend of up to 30%. In September 2018 the large trailing suction hopper ( TH ) dredge Prins der Nederlanden ( Below ) is powered by a biofuel blend resulting in a substantial CO2 reduction.

Marco Kuijpers, senior manager Offshore Netherlands at TenneT, welcomes this step by Boskalis, “In addition to the safe, efficient and reliable transportation of electricity TenneT’s objectives include doing this in a sustainable way. To achieve this we take various measures to mitigate or offset the impact of our activities on the environment and we are working towards making our operations climate-neutral by 2025. And so we warmly applaud Boskalis’ initiative to use a biofuel blend to power its vessels. This results in an even more environmentally conscious approach to a sustainable project like the Borssele offshore grid.” Using biofuel is one aspect of the ‘Boskalis on Bio’ program, for which the company recently signed a long-term partnership with biofuel supplier GoodFuels. The program is aimed at achieving a 35% reduction in the CO2 emitted by the Boskalis fleet and equipment in the Neth-erlands in the next five years. Various sea trials conducted by Boskalis have shown that sustainable biofuels lead to an impressive reduction in CO2 emissions of up to 90% compared to fossil fuels, and are also much more effective than alternatives such as liquefied natural gas (LNG). On the Marker Wadden project Boskalis performed dredging work for six months using a B50 biofuel blend, consisting of 50% residual products from the paper in-dustry which also resulted in a huge reduction in CO2. Boskalis now uses this fuel to power not just its vessels but also its dry earthmoving equipment and trucks in the Netherlands.


Boskalis Stays BusyContinued

Boskalis wins EUR 100M dredging contract from LNG CanadaIn October 2018 Royal Boskalis Westminster N.V. (Boskalis) said that it will be executing the dredging scope for the development of the first large-scale LNG export facility in Kitimat, Canada (LNG Canada) following the final investment decision by the shareholders. The contract value is approximately EUR 100M. The dredging scope includes the removal and remediation of contaminated and non-contaminated sediments at the site of the future facility in order to provide the required physical space and marine access for the construction of LNG Canada. For these activities Boskalis will deploy a medium-sized trailing suction hopper ( TH ) dredges, cutter suction ( CS ) dredges, backhoe ( BB ) dredges and a crane barge. Boskalis was involved from the early stages of this development illustrating the early cyclical exposure dredging has on green field LNG developments. The dredging activities are expected to continue into 2020. LNG Canada is a joint venture comprised of Royal Dutch Shell, Petronas, PetroChina, Mitsubishi and Korea Gas Corporation. The liquefied natural gas (LNG) export facility will initially consist of two LNG processing units with the first LNG expected to be processed before the middle of the next decade. Boskalis’ strategy is aimed at benefiting from key macro-economic factors which drive worldwide demand in markets, expansion of the global economy, increase in energy consumption, global population growth and the challenges that go hand in hand with climate change. This contract award is closely related to the increase in energy consumption.

Boskalis to build road in Dutch - Belgian border region In October 2018 Royal Boskalis Westminster N.V. (Boskalis) won the N69 New Connection tender for the construction of a new road connection linking the N69 provincial road south of Valkenswaard with the A67 motorway at Veldhoven in the south of the Netherlands near the Dutch-Belgian border. The project includes numerous new civil engineering structures as well as adaptation of the existing road network. The final award of the contract with a value of over EUR 80 million by the province of Noord-Brabant will take place in December. The execution phase of the project will start in early 2019 and last three years, followed by a 10-year maintenance period. During the execution phase, Boskalis will construct a new access road to the N69 of around 8.5 km long, reconstruct a 7.3 km stretch of the existing N69-Zuid road between the Belgian border and Valkenswaard and adapt two other connecting roads. Through this project, the province aims to improve traffic distribution, traffic safety and livability in the Dutch-Belgian border region. During execution of the work Boskalis will use biofuel to reduce CO2 emissions from its equipment. Boskalis will realize this project using the broad expertise that is present in its Dutch organization in the areas of raw materials, earthmoving, concrete technology and road construction.

Boskalis’ SMIT Salvage wins salvage contracts from US NavyIn October 2018 Royal Boskalis Westminster N.V. said its (Boskalis) subsidiary SMIT Salvage acquired two five-year marine salvage contracts to serve as the exclusive marine salvage and engineering support contractor for the Naval Sea Systems Command (NAVSEA), the division of the U.S. Navy responsible for engineering, building, buying and maintaining Navy ships and submarines. SMIT Salvage will provide the U.S. Navy with marine salvage, salvage-related towing, ocean engineering and towage services in the event of an emergency or incident in two of the three geographic zones in the world as defined by the U.S. Navy.


SMIT Salvage held a contract for one zone covering the area between the Suez Canal and the dateline - the imaginary line down the Pacific Ocean on which the calendar day begins and ends - for a number of periods totaling more than 30 years, which it was able to renew. In addition, the contract for a second zone between the dateline and the U.S. West Coast was successfully acquired. With the award of the third and final contract to its U.S. partner Donjon Marine, the companies are able to provide world-wide marine salvage support to the U.S. Navy. SMIT Salvage and Donjon Marine established the joint venture Donjon-SMIT to provide salvage services to vessels trading in U.S. waters under the Oil Pollution Act of 1990 (OPA-90) and related U.S. state regulations. www.boskalis.com m

Two new vessels for Dutch DredgingOn 24 September 2018 dredging contractor Dutch Dredging welcomed two new vessels to its fleet last week during the naming ceremonies for the Papillon and the Fregate. Both vessels will go to work in the ports of Cayenne and Kourou in French Guiana. The newcomers were delivered to Boer Remorquage SARL, a joint venture involving Dutch Dredging and Iskes Towage & Salvage. The investment is a response to the twelve-year contract that the consortium signed in 2016 with the Grand Port Maritime de Guyane. In addition to maintenance dredging work, both vessels will be used to assist shipping and as standby and fire-fighting vessels in emergencies.

Hybrid driveThe Fregate is the more unusual of the two. The 29.2-metre-long vessel is not only a dredger (with the AIRSET water and air pressure method) and tug at the same time, it has also been fitted out with a hybrid drive, allowing it to sail on electricity. The Fregate is a Damen WID-Tug-2915-HYBRID built by the Polish yard SAFE in Gdansk.

Shallow draughtThe Papillon is the smaller of the two. The tug is 22.7 m long (212 gross tonnage) and it was completed earlier this year by Damen Shipyards Hardinxveld in line with French regulations. The ASD Tug 2310 SD (shallow draught: 3.1 m) will mainly be used for assistance in Kourou.

Beauty queensThe naming ceremony in Cayenne was performed by two genuine beauty queens, namely Sarah Ringuet, or Miss Kourou, who named the Papillon, and Ruth Briquet, Miss Guyane, who named the Fregate.

Specific requirementsHugo van de Graaf, co-director of Dutch Dredging said, ‘These two vessels are the result of exceptional teamwork. Our client
