Aligning industry towards sustainable future

As it continues to drive the maritime energy transition, Damen Shipyards Group has unveiled its first Electric Cutter Suction Dredger (ECSD) 650. With electric motors powering the dredge system, the ECSD 650 makes possible zero emissions dredging projects. The electric power provides a significant reduction in noise, adding an extra tier of sustainability and ensuring the dredger’s suitability for projects in densely populated and environmentally sensitive areas.

Modular convenience

The ECSD is a modular dredger, based on Damen’s successful standardised shipbuilding philosophy, dismountable for transportation and easy assembly in the remotest of locations. Due to the standardisation of the design, Damen was able to very quickly produce this sustainable product, simply exchanging the diesel motors for electric ones, without need for re-engineering. Standardisation further ensures the easy adaption of the ECSD to suit local power supplies.

Electrical nerve centre

On the conventional CSD 650, the rear side pontoons serve only to provide buoyancy; in the ECSD the starboard side pontoon becomes an electrical nerve centre. The dredger’s low voltage system equals easy maintenance with no requirement for special crew training. Meanwhile, the associated reduction in vibrations during dredging ensure a comfortable experience for those on board.

Connect, align, integrate

Damen sales manager Sjoerd de Bruin says, “The ECSD is just one example of the products and services that Damen is pioneering as we fix our focus on our goal: to be the most sustainable shipbuilder. Our role in this is not just to build electric vessels. As integrator we provide the connection, linking and aligning stakeholders from industry and academia. In this way we build a knowledge network that encourages the wider development of sustainable solutions and ensures the long-term viability of the maritime industry.”

The 3 Es: An umbrella of sustainability

Damen’s work on the electrification of the maritime industry falls under the so-called E3 umbrella. That is, environmentally friendly, efficient in operation and economically viable. The shipyards group is currently working on a number of projects for electric vessels.

Cleanly connected communities

This includes seven fully-electric Damen Ferries 2306 E3 for the city of Copenhagen, Denmark. These ferries have a completely emission-free propulsion system, which will reduce the total emission of public transport in Copenhagen by 2.5% for CO2, 10% for NOx and 66% for particulate matter. Damen is also building two Road Ferries, 6819 E3 and 9819 E3 to operate in Ontario, Canada. These will be the first fully electric ferries to operate in North America and will reduce CO2 emissions by as much as 7 million kg per year.

The six Island Class Ferries – Road Ferries 8117 E3 – that Damen is building for BC Ferries in British Columbia, Canada, will sail with a hybrid propulsion system that can be easily converted to full-electric in the future when the appropriate infrastructure is in place locally.

Completing the circle

An order from the Port of Auckland, New Zealand, sees Damen constructing the world’s first fully-electric ship-handling tug with 70 tonnes bollard pull. The RSD Tug 2513 was already an exercise in sustainability, being fully prepared for IMO Tier III compliance and featuring numerous energy-conscious characteristics running throughout its design. With 80% of electricity in New Zealand coming from wind and hydropower, Damen’s tug completes the circle in a zero emissions operation.


Jenkins Marine goes digital for dredging works

Jenkins Marine are excited to announce investment in new Prolec dig control system for dredging works. Supplied and installed by locally based James Fisher Prolec, the new electronic dig control system can be programmed with a customer’s detailed dredge design profile and existing seabed survey.

The excavator operator can control the bucket with much greater accuracy and has a visual display in the cab to show where they are, and progress over the area.

Significant benefits are found when dredging with Prolec installed by ensuring optimum accuracy and efficiency covering the target site. Digging slopes and pockets is made simpler, and there is a greater level of control when dredging near contaminated or sensitive material.

Regular progress information can be sent to clients and any isolated points of significance, such as underground obstructions, cables and outfalls, can be marked and displayed to the operator to assist identification and positioning.

The duel hemisphere GPS receivers are even sensitive enough to automatically adjust for changes in tidal levels throughout the day. Although Jenkins Marine have been using versions of this technology for over 10 years the advances in data processing and equipment means less technical dependency and improved ease of use for all involved.

The updated technology is already being put through its paces on dredging works in Cowes and Portsmouth Harbours for some of our regular customers, and we look forward to analysing the final results!

Listen to the story (FreightComms AudioPost)

Royal Boskalis Westminster N.V. has been awarded two contracts in Finland by the Finnish Transport Infrastructure Agency, the Port of Helsinki and the City of Helsinki with a combined contract value of EUR 32 million.

In the Port of Helsinki, Boskalis will deepen de Vuosaari fairway and harbor basin from eleven to thirteen meters and utilize a part of the dredged material for the development of Helsinki’s Hernesaari area, which is close to the center of the city. The activities will commence immediately and are due to be completed by the end of 2021.

‎For the harbor deepening scope a volume of one million cubic meters of clay and moraine material will be dredged and 0.8 million cubic meters of rock will be removed from the seabed by means of drilling and blasting.

Part of this material will be transported by vessel to the Hernesaari area and reused for the reclamation of 6 hectares of land on which offices and residential housing for 7,000 people will be developed in the coming years.

For these activities Boskalis will deploy a variety of specialized dredging equipment including two large backhoe dredgers, a grab dredger, a drilling barge and various hopper barges.

Boskalis’ strategy is aimed at benefitting from key macro-economic factors which drive worldwide demand in our markets: expansion of the global economy, increase in energy consumption, global population growth and the challenges that go hand in hand with climate change.

These projects are largely driven by growth in global trade and the trend towards larger vessels with deeper drafts as well as population growth in major cities.

Listen to the story (FreightComms AudioPost)

The Suez Canal Authority and Royal IHC successfully launched cutter suction dredger MOHAB MAMEESH. The launch took place at IHC’s shipyard in Krimpen a/d IJssel, The Netherlands.

The 29,190kW heavy-duty rock CSD has been specifically designed in close cooperation with SCA, and will be used to maintain and improve the Suez Canal, which connects the Mediterranean and Red seas. The vessel, characterised by its long slender shape and high spud towers, will have an overall length of 147.4 metres and provide a maximum dredging depth of 35 metres. Equipped with one submerged – and two inboard – dredge pumps, the installed cutter power will be 4,800kW.

“Launching the MOHAB MAMEESH dredger reflects the fruitful strategic cooperation between IHC and SCA, on which we count to modernise our fleet of dredgers with advanced units,” says the Suez Canal Authority’s Chairman and Managing Director Admiral Osama Rabie.

“I would like to extend my sincere appreciation and gratitude to everyone involved in this project for their dedication in continuing to build the dredger according to the agreed schedule and specifications. This is despite the exceptional circumstances caused by the global outbreak of the coronavirus, and demonstrates the distinguished professionalism of IHC in delivering mega projects.”

IHC’s CEO Gerben Eggink adds: “Our strong partnership with SCA has resulted in the build of a powerful and impressive vessel that will enable it to execute work at a top level while opening up the full potential of the vessel. We are proud that, in these challenging times, we have achieved this milestone and are therefore grateful for the commitment and hard work of everyone involved.”

This CSD is one of two vessels currently under construction at IHC for SCA. The sister vessel, the 26TH OF JULY, is expected to be launched in the autumn of 2020.
