Addressing the New IMO Guidelines for Second Generation Intact Stability
The common perception of intact stability has remained largely unchanged over the last few decades, where a vessel’s stability is evaluated using classical and static means: limits on righting arms, residual areas, and determining maximal VCG (or minimal GM) composite curves. These methods are familiar to most naval architects and are taught at a fundamental level in most naval architecture engineering programs.But repeated incidents of dynamic failure in recent decades brings question to the adequacy of classical static stability criteria to provide a complete understanding of…
World's First LPG-fueled Gas Carrier Completes Sea Trials
The world's first very large gas carrier (VLGC) to run on liquefied petroleum gas (LPG) dual-fuel propulsion technology has completed sea trials, shipowner BW LPG announced Wednesday.BW Gemini and its newly retrofitted LPG propulsion technology were tested to their safe limits by an expert team from engine manufacturer MAN Energy Solutions, BW LPG’s Newbuilding & Projects and Technical departments, and classification society DNV-GL, who awarded the required classification certificate to following satisfactory performance.
Arctic Shipping Creates Insurance Headaches as Routes Open
When Captain Will Whatley guides a ship through Arctic waters, he is starkly aware of what can go wrong.Double the manpower is needed to navigate. Lookout shifts are kept to just one hour, so sailors don't lose concentration and miss a mass of floating ice. Big icebergs show up on radar, but smaller, truck-sized "bergy bits"—even more dangerous—can be missed, the captain says.The cold can freeze equipment and the earth's magnetic field disrupts compasses. If anything goes wrong…
New Design Tool Uses Digital Twin, Real World Enviro Data to ‘Perfect’ Electric Ferry Design
Norway's biggest ferry company has ordered two new ferries from Havyard Design & Solutions, the first to use Havyard LAB's new three-step tool to become safer and more environmentally friendly. Havyard LAB offers a new three-step ship design tool that incorporates a vessel’s digital twin situated in simulated local conditions, a process it believes will result in a ship that is carefully adapted to its work and the waters in which it will be operating, while also cutting energy consumption, emissions and operating costs.
First Large Commercial Hydrogen Carrier Developed
A design for the world’s first large liquefied hydrogen carrier has been granted approval in principle (AIP) from the classification society Korean Register and flag state Liberian Registry.The 20,000 cubic meters class vessel was developed by Hyundai Heavy Industries Group and Hyundai Glovis in partnership with the Korean Register and the Liberian Registry, and HHI Group’s Korea Shipbuilding & Offshore Engineering (KSOE) and Hyundai Mipo Dockyard (HMD) announced they have received the AIP on Thursday.Alfonso Castillero…
Tech to Fight Container Fires
Fire safety has become a major concern in the container shipping industry, in particular, with vessels of 20,000-TEU and more entering the market. A fire in just one container can have catastrophic implications for the whole of the cargo. The very nature of container shipping means that the cargoes are in general finished goods of high value. Insurer Allianz gives the example of a March 2018 fire onboard the Maersk Honam southeast of Oman. At the time the ship was carrying 7,860 containers, corresponding to 12,416 TEU.
Op/Ed: Considering Alternative Energy Sources for Ships
Hydrogen or battery technologies? Strict regulations force shipowners to consider alternative energy sourcesThere are more than 60,000 ships in the world, which engines emit almost 2.5% of the world's greenhouse gases. The automotive industry has made rapid progress towards electrification and there is more and more talk of hydrogen solutions for trains, at the same time the transition to non-fossil fuels has been slower in the shipping industry.Energy for moving ships can originate from a wide variety of sources. Ships have been sailing powered by wind for millenniums.

An ammonia-fueled tanker design developed by South Korean shipbuilder Samsung Heavy Industries (SHI) has received approval in principle (AIP) from classification society Lloyd’s Register (LR).The project to develop the novel, emissions-slashing aframax tanker was announced in January as maritime stakeholders consider cleaner-burning ammonia and other zero-carbon options to meet the International Maritime Organization’s (IMO) target to halve shipping’s greenhouse gas (GHG) emissions from 2008 levels by 2050.Together…
Will Customers Redefine Design and the Science of Marine Propulsion?
It is “pre-COVID ” April of 2018, and 174 member states of IMO adopt a new strategy to reduce greenhouse gases from shipping. The meetings are considered “urgent” and the target is to reduce carbon emissions in half by 2050. Prior to those “targets” shipping dealt with regulations to address SOx and NOx reductions. Most of which have resulted in limited success due to infrastructure problems and a consideration as a temporary fix.The technical world has responded with low sulfur fuels, LNG, and methanol to work towards the target.
Mitigating Underwater Noise

What will Cruise Ships Look Like Post-COVID-19? Look to Marine Interiors @ SMM 2021
As the COVID-19 pandemic lingers, talk turns to all aspects of interior design of ships, particularly cruise ships that can carry thousands of passengers in relatively close quarters. In response to the coronavirus pandemic, SMM has been postponed to February 2-5, 2021. According to the organizers, as of today, about 90 percent of exhibitors have committed to the new date. Apart from Green Shipping, Security & Defence, and Digitalization, the interior outfitting of passenger ships…
Robert Allan Ltd. Celebrates 90 Years of Business
In business, as in life, after major anniversary milestones like 60 (Diamond) and 75 (Diamond or Sapphire), it seems that every year after that is worth celebrating. However, 90 years is somewhat in the nether regions of celebrations; certainly, a major achievement after say 75, but not quite the centenary either. However, Robert Allan Ltd. has been an active and growing business now for 90 years and we believe that is worth celebrating in a time when it feels, frankly, that there is not a great deal to celebrate.The family lore has always been that my grandfather…
Insurers Discuss Container Casualty Causes
Handling of steel boxes throughout the shipping, ports and logistics supply chain has historically grown exponentially, putting strains on a range of operational procedures and the physical hardware employed to handle the steel boxes, particularly onboard ships. A recent webinar organized by the Thomas Miller managed insurance mutuals, container freight specialist TT Club and protection & indemnity insurer, UK P&I Club, revealed the diverse range of factors important to safe container ship operations and the security of the container stacks they carry.
