Houthi rebel drone attacks on vessels traversing the Red Sea and Suez Canal route, accounting for 10% of global trade, have exposed the shortcomings of current ship alert systems.The unpredictability and increased frequency of these attacks have created a challenging security environment for ships passing the area via the Bab el Mandeb strait, posing a substantial risk to seafarers and maritime trade by endangering the safety of the crew and cargo.Initially focused on Israel-related ships in solidarity with Hamas…

Pelagus 3D said Wednesday it had delivered a Return Oil Standpipe at Kobe, Japan, to be installed on Wallenius Wilhelmsen's RoRo vessel TYSLA. The collaboration involved Kawasaki Heavy Industries and Wilhelmsen Ship Management.Traditionally, the procurement, fabrication, and delivery of specific spare parts has been a time-consuming process, often leading to costly downtime for the maritime and offshore industries. However, with the advent of Additive Manufacturing (AM), also known as 3D Printing…

Clean Technology Lasers: A New Tool to Remove Corrosion and Scale

(Photo: Laser Photonics)

Laser systems quickly remove corrosion and scale from metal surfaces with less preparation and mess than traditional techniques.In the maritime industry, corrosion and scale (where rust penetrates a metal surface) can quickly become an issue in an outdoor, salt sea spray laden environment. When sea spray evaporates, it leaves salt behind, leading to saltwater staining and accelerated corrosion.So, most shipbuilders as well as those responsible for maintenance and repair understand the value of treating metal surfaces to remove corrosion…

The Navy wants, and needs, more ships; but it can’t build them fast enough.While the U.S. Navy aims to achieve a 355-ship fleet, it is decommissioning older (and some not so old) ships at about the same rate it's adding new ones.A Congressional Research Service report stated that, as of April 17, 2023, the Navy included 296 battle force ships. "The Navy projects that under its FY2024 budget submission, the Navy would include 293 battle force ships at the end of FY2024 and 291 battle force ships at the end of FY2028."But there is progress…

Remote Survey is the New End-Game

More than remote witnessing, more than remote data analysis, remote survey techniques are now going to aid the shift to full vessel autonomy.The technology that enables a robot to safely navigate an environment it has no prior knowledge of is called Simultaneous Localization and Mapping (SLAM). “It is the key to autonomy for any aspiring can-do inspection robot.” That’s according to ScoutDI, a participant in the REDHUS project led by DNV which is developing a prototype inspection drone.SLAM is not a specific, copyrighted piece of technology.

A well-built, modern vessel can be expected to outlive her original engines. The challenge for those representing the owners, is to choose new engines that match or exceed the capabilities of the original power. Consideration will be given to replicas of the original engines. However, availability and suitability may limit this.These were some of the considerations confronting the Thai Marine Department when they decided to put their 41.85 by 3.9-meter oil response vessel back into service.

Two load-bearing pillars of Norway’s leading maritime industry cluster in Sunmøre on the country’s west coast – offshore energy and the expedition cruise sector – took severe knocks from plunging energy prices in the 2010s followed by COVID-19. However, a recent tour of the region found the cluster in recovery mode.At the time, the cluster’s diversification strategy was to dive into the emerging expedition cruise sector: small, highly sophisticated ships designed to operate in some of the world’s most sensitive environments incorporated features including the highest ice-class…

Green Marine: Electrification is the Power behind ‘Future-Proofing’

There's an “electrification of the seas” happening for navies around the world.Whether it's to achieve greater military capabilities, operational economics and efficiencies or to be better stewards of the environment.There's a trend moving from direct mechanical drives towards more flexible electrical propulsion systems. Ships can still have the same propellers and engines, but they now have a much more flexible power system architecture that benefits design, operations and sustainment.“With an electric propulsion system, we can connect to the same gas turbine or diesel.

When he served as the commander of NWSC Carderock, Mark Vandroff woke every morning knowing that his counterpart in China had just gone to bed and had spent that day trying to make China’s Navy superior. His job, he figured, was to “get cracking and work to make our Navy even better.” Now the CEO at Fincantieri Marinette Marine (FMM), Vandroff brings that passion for navy shipbuilding – and delivering on the new USN Constellation-class frigates contract – to work every day.Introducing a new class of warship usually comes with a heaping helping of pain, from cost overruns to technical glitches.

U.S. Navy: DDG(X) is a Large Surface Combatant with Room to Grow

The future guided-missile destroyer Jack H. Lucas (DDG 125) is launched, June 4, 2021, at Huntington Ingalls Industries, Ingalls Shipbuilding division in Pascagoula, Miss. Jack H. Lucas is the first Arleigh Burke-class guided-missile destroyer to be built in the Flight III configuration. The Flight III upgrade is centered on the AN/SPY-6(V)1 Air and Missile Defense Radar and incorporates upgrades that provide enhanced warfighting capability. The Flight III baseline begins with DDG 125 and will c

“DDG-51 hull form is maxed out in nearly every mission area. Meanwhile, the threat marches on.”Rear Adm. Paul Schlise, director for surface warfareThe U.S. Navy’s highly successful USS Arleigh Burke (DDG 51) surface combatant program is still going strong and growing in capability. Nearly 40 years later, new ships are still being built. But, the navy said, the ship cannot support the systems of tomorrow needed to meet the future threat.“DDG 51 has been in production for over 40 years with basically the same hull we started with in 1985…

Introducing a new class of warship can be fraught with pain, and the first ship is always the hardest – almost always behind schedule and over budget. And trying something new and transformational is even harder.The U.S. Navy knows this from experience. That’s one reason why the Navy is opting for a lower risk design for its next class of guided missile frigates (FFGs).Just about every new class has experienced a rough start. Although the USS Arleigh Burke-class of guided missile destroyers (DDGs) today represent the largest and most successful class of warships…

Don’t let the titanium metal walls or the sapphire windows fool you. It’s what’s on the inside of this small, curious device that could someday kick off a new era of navigation.For more than a year, the avocado-sized vacuum chamber has contained a cloud of atoms at the right conditions for precise navigational measurements. It is the first device that is small, energy-efficient and reliable enough to potentially move quantum sensors — sensors that use quantum mechanics to outperform conventional technologies — from the lab into commercial use…

US Navy: 355-Ship Fleet is the Mandate, Funding It is Fuzzy

(U.S. Navy photo by Morgan K. Nall)

As Congress wrestles with the budget, there is at least a bipartisan consensus that defense spending should grow, and that includes growing the Navy’s fleet. The current goal is 355 ships, an admirable goal, but an objective that faces many cost hurdles. The surface fleet (which excludes submarines and aircraft carriers) needs to grow in capability and capacity. The numbers of ships being procured or envisions would increase as the total n umber of ships increases, but the number in this story represents current program status.
