Always better and less expensive when designed in from the start.

Suppressing thruster tunnel drag to save energy and costs Shipbuilding and hydrodynamics experts at Fincantieri and DNV have collaborated closely on a solution to address drag induced by bow thruster tunnels. It can help minimize ship hull resistance and reduce fuel consumption and carbon emissions.

Deep Dive into a Vessel's Heart! Got a chance to get a deep dive into the heart of a vessel's propulsion system today! Analyzed the configuration of the dual main engines and twin generators, impressed by their design and efficiency. Examined the oily water separator, a crucial component for environmental protection, understanding its critical role in keeping our oceans clean. Also closely inspected various other engine room machinery, gaining a deeper appreciation for the complexity of these marine marvels. Fascinating to see how these systems work together to keep the vessel running smoothly. #marineengineering #shiplife #vesselinspection Voyage Marine Group Voyage Marine Automation Voyage Institute of Technology

Noise Control Engineering is conducting a study for the Maritime Administration (MARAD)’s META program in Casco Bay, Maine that will help assess the potential for reduced underwater noise from vessels utilizing hybrid-electric power. For the study, our team is comparing the underwater noise generated by two Casco Bay Lines ferries: the conventional diesel-geared M/V Machigonne II and the newly built, battery-electric M/V Battery Steele. The data we collect will be used to identify how future power generation systems designed to reduce greenhouse gas emissions can be implemented aboard vessels to lower the impact of underwater noise on marine life. #underwaternoise #radiatednoise #noisecontrol Photo by Casco Bay Lines

Being named after the Nordic God of “innocence, light, joy, spring and beauty” is a bold statement, but Rohde Nielsen’s “Balder R” certainly lives up to the hype. This Split Hopper Suction Dredger’s hull is split in two halves and hinged at the deck so that the ship can open at its bottom to discharge dredged material, and that’s not even the impressive part! 🌊 Power and Precision 📍 At a gross weight of over 5,000 metric tonnes and almost 11,000kw (15,000hp) of total power, the Balder R is likely the biggest and most versatile dredger in its class, whilst a highly advanced Dynamic Positioning system enables extremely precise manoeuvrability.  She is just one of a fleet of dredgers that are working around the clock to deliver an ultra-fast track project on time. 🌱 Minimal Environmental Impact This state-of-the-art vessel far exceeds all regulatory and industry standards, and its advanced technology ensures a 20% reduction in fuel consumption.   What’s more, on this project she is dredging the temporarily stored sand and bringing it back to its original location by reverse-pumping through suction-pipes, ensuring minimal environmental impact. In the video you can see a full cycle of dredging and unloading, which we accelerated (just slightly!) into a 20 second clip. #StreamTecSolutions #RohdeNielsen #Dredging #SustainableDredging #AdvancedMarineTechnology #GasPipeline #MaritimeExcellence #LNG #EngineeringMarvels #Hydrogenready

A 'Wind Limit Rose' in ship mooring analysis is a graphical representation illustrating various wind speed and direction combinations, revealing potential challenges and safety violations for a specific vessel's mooring. This tool is of paramount importance for assessing the impact of wind conditions on a ship's mooring arrangement, offering insights into motions, forces in mooring lines, and stresses on bollards and fenders. As an illustrative example, take into account the mooring hardware response for a containership, focusing on its most critical scenario with winds from West-South-West to North. Here, the vessel can handle extreme winds up to approximately 20 knots, reaching the maximum allowable sway. In simpler terms, higher winds could lead the vessel to blow off the dock. Moreover, substantial constraints arise from bollard and mooring line limitations. The wind limit rose discloses that these limits are exceeded at wind speeds greater than roughly 27 knots, inevitably resulting in the vessel colliding with the quay. **Image sourced from the technical report 'Ship Hydrodynamics and Mooring Analysis - Berth 6 Bulkhead Extension, Port of Port Arthur, TX.'

https://lnkd.in/eS4aT7Dn I will always insist on drawing a proper rhum line on a paper chart before leaving the dock. It's an integral part of the passage plan. It allows you to see the geometry, plot currents, tides, wind direction, courses to steer, visualize hazards, record positions physically as the passage progresses (2B pencil, mind, for easy rubbing out) and jot down notes. It is also a legal document along with the log book in case of boarding by the authorities or an accident investigation. But fundamentally, in cases of electric or equipment failure, how would you know where you are?

Hydrographic surveying is still not quite entrenched in our waters due to many factors including the cost of Multibeam Echo Sounders (MBE) and RTK technology and skills to operate these relatively sophisticated equipment. Let's embrace the widespread use and communicate the results to decision makers
