Damen Presents New Charging Concept for Offshore Vessels

Damen Unveils New Offshore Vessel Charging Concept

Damen Shipyards Group has unveiled a cutting-edge offshore charging concept aimed at significantly reducing emissions during the active phase of offshore wind farms.

The groundbreaking system plans for a wholly electric crew transfer vessel (CTV) that can recharge at a turbine or a Damen’s commissioning service operations vessel (CSOV) equipped with a charger.

Although the infrastructure for turbine-mounted rechargers is not yet fully developed, vessel-to-vessel charging presents an immediate opportunity for CTV owners and operators to invest in the sustainable technology of the future, according to Mark Couwenberg, Product Manager Service Operations Vessels at Damen.

Couwenberg explains, “Offshore charging is crucial for a fully electric CTV operation. Traditionally, this would rely on charging infrastructure at offshore wind farms. However, as builders of both CTVs and CSOVs, we thought of including the charging scope within our own vessels. This can be implemented with a diesel-powered CSOV or a fully electric version. Though the fully electric version is preferable for reducing emissions, this solution allows CTV operators to invest today, readying for the wider distribution of fully electric CSOVs in the future.”

The challenge lies in installing an extensive battery system on board a CTV due to weight and space restrictions. By installing the system on the larger, less space-sensitive CSOV, the smaller vessel can access the energy it needs without sacrificing its capabilities.

Damen further notes that using the CSOV as a charging host offers additional benefits. The stern of the ship is lower than a turbine, providing easier access to the charger. Additionally, the CSOV can change its position, enabling the CTV to charge in the most protected position relative to wave conditions.

Damen’s charging system concept was developed in collaboration with UK-based MJR, an expert in offshore charging systems. The CTV would connect via a bell mouth that captures the charger lowered from a reel on the CSOV’s aft deck.

Once the personnel have disembarked, the vessel can connect using a highly automated, safe process. It is anticipated that charging could be completed in 2-3 hours, contingent on the operational profile.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.

Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
