Fuel, Propulsion, Emissions & the Decision to Scrap or Refit

BW LPG – the world’s leading owner and operator of LPG vessels – will retrofit another three MAN B&W 6G60ME-C9.2 type engines to MAN B&W 6G60ME-C9.5-LGIP dual-fuel types, capable of operating on fuel oil and LPG.

When the maritime history books are written, 2020 will be viewed as a year of pivots, re-invention and new paradigms. By February 2020, concerns about marine fuel’s sulfur content quickly shifted to near-term disruptions induced by the COVID-19 pandemic. By mid-year, with demand recovering, the conversation turned to longer term questions surrounding the moves towards reduced maritime carbon emissions and alternative fuels. How will this all impact the current fleet?Perhaps the most extreme reaction to the shifting landscape is the ongoing “pivot” of Scorpio Bulk (NYSE: SALT)…

Oslo-listed BW LPG, the world’s largest LPG shipping company, ordered Wärtsilä LPG Fuel Supply System (LFSS) for retrofit to three very large gas carrier (VLGC) vessels. BW LPG had previously ordered four Wärtsilä LFSS’ in 2018, and an additional eight systems in February 2020. The initial order was placed following Wärtsilä’s successful full-scale testing of the system in 2018 with a full-sized two-stroke marine engine operating on LPG fuel, which was the world’s first such testing protocol.

The Estonia Disaster: A Bottomless Source of Learning

© Karl Allen Lugmayer / Adobe Stock

The sinking of the Estonia ro-ro passenger ferry stands out as one of the most disastrous accidents in modern times. The tragedy claimed 852 lives and the wreck was declared a marine graveyard. At first glance, the sinking seems to have been triggered by a single technical failure only minutes before the point of no return, with no warning signs. The first objective of this review was to verify whether the pattern of typical major accidents can be found in the Estonia disaster. The usual pattern involves multiple human errors combined with an immature organizational culture.

Top Maritime Trends of 2020: Decarbonization is Blowing in the Wind

Wind Propulsion Principles is a complete handbook dealing with all currently applied wind propulsion technologies on board, seen through the lenses of the aerodynamic and hydrodynamic effects, ship operations in weather, design implementation and investment yield assessments, so that a unified roadmap for decision making is available to the shipping community.

The global shipping industry is going to face a big challenge during the coming years when regulators, investors and stakeholders demand the drastic reduction of CO2 and other GHG emissions during ship operations. But in reality, the change is already underway.Since 2013, any newbuild ship over 400GRT has been obliged to comply with a specific Energy Efficiency limits – the well-known Energy Efficiency Design Index (EEDI). It is about to enter an accelerating phase propelled by the recently released IMO GHG reduction strategy.

Great Ships and The Ship Designer’s Curse

For the Design issue Greg Trauthwein asked me to write about a favorite ship design. I have no favorite ship design, or should say there are simply too many that are truly worthy of mention. But when considering favorite designs, ship designers (and builders) do carry a strange curse. Unique among engineers (and artists, architects, and industrial designers) their creations only live for about 30 years. With very few exceptions, in their own life time, ship designers get to see the disassembly of most of their creations. I am not aware of any other creations that are so readily tossed aside.

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…

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

Through a decade of research and development work, including cooperation with Sintef Ocean, Havyard LAB has now arrived at a three-step tool with a digital twin of the ship in a virtual ocean to per-fect the ship's design in order to cut energy consumption, emissions and operating costs. Photo: Havyard

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.

Tech to Fight Container Fires

Photo: Survitec

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

© a_medvedkov / Adobe Stock

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.
