“Not only does the top of the river move, but the bottom of the river also moves.” - James Bodron, U.S. Army Corps of Engineers, Mississippi Valley Division, Regional Business Director.Dredging was the Herculean act that allowed much of the U.S. economy to keep chugging along as usual, at least for Midwest and Central states, as drought conditions threatened to shut down river traffic on the Mississippi River and its tributaries, during fall and winter 2022 and early 2023.The full scope of these U.S.

© Delphotostock / Adobe Stock

When compared to other major river navigation routes around the world, the St. Lawrence River is a favored waterway.It flows from the mouth of Lake Ontario, at an altitude of 250 meters. From its source to the Gulf, the river travels 1,197 kilometers, and is fed by several tributaries including the Ottawa, Richelieu, Saint-François and Saguenay rivers.But the effects of climate change are being felt. The marine industry is adapting. It is currently embarking on a shift towards…

GTT Develops Balast Water-Free LNG Feeder & Bunker Vessel Concept

Credit: GTT

French firm GTT has developed a versatile LNG feeder & bunker vessel concept for worldwide operation without the use of ballast water.Every day, many ships carry on board a considerable quantity of seawater as ballast over the oceans. Technically, this is needed in empty or partially loaded conditions, in order to maintain seaworthiness, reach sufficient draft for propeller immersion, and avoid excessive bow slamming.Such ballasting requires investment for the onboard systems and leads to substantial operating costs.

Ship Designed to Collect Ocean Plastic and Convert It to Clean Hydrogen

(Image: H2-Industries)

An innovative ship is being designed to collect plastic waste from the world’s oceans and then convert it into clean hydrogen, allowing surplus hydrogen to be shipped back to shore.At least 14 million tons of plastic end up in the ocean every year, according to the International Union for Conservation of Nature (IUCN). This type of debris—which is currently the most abundant type of litter in the ocean, making up 80% of all marine debris found from surface waters to deep-sea sediments—could more than double in oceans and other bodies of water by 2030…

Venezuelan state-run oil firm PDVSA this week will resume exports of diluted crude oil (DCO) for the first time in nine months, according to a document seen by Reuters.Since U.S. trade sanctions were imposed on PDVSA in 2019, a lack of diluents, especially heavy naphtha, has hurt its ability to produce exportable grades from its largest production region, the Orinoco Belt. Its extra heavy oil must be diluted with naphtha or condensate for transportation and exports.A key swap…

Marine shipping drives 90% of global trade, moving over 11 billion tonnes of containers, solid and liquid bulk cargo across the world’s seas annually. Almost all consumer products we buy — or the raw materials required to make them — arrive at Canadian ports via ship.Each year, Canadian port facilities handle about 340 million tonnes of goods, worth about $400 billion. Roughly 25% of Canadian exports and imports, by value, are transported by marine shipping.Despite their economic importance…

Some corals have lived for centuries at the fringes of Mauritius. Now smothered for days in heavy fuel oil spilled from a wrecked Japanese ship nearby, parts of those reefs may be in trouble.The full impact of the toxic spill is still unfolding, scientists say. As the Indian Ocean island's residents scramble to mop up the oil slicks and clumps, they are seeing dead eels and fish floating in the water, as fuel-soaked seabirds limp onto shore.Satellite images also show the 1,000…

The Path to Zero: Creating a Pathway to Carbon-Negative Shipping

Dry ice formed by cooling exhaust gasses to -120°C is formed into Carbon Descent Vehicles that sink to depths of about 500 meters, where they penetrate the seabed, storing CO2 safely as liquid CO2 and CO2 hydrate. Image: MDC

Greenhouse gas emissions capture and storage may be a more practical alternative to emissions reduction for meeting the IMO’s 2050 CO2 target. Tom Mulligan reports.Shipping emits close to 1 billion tons of CO2 each year and the shipping industry needs carbon-free solutions to achieve the IMO’s 2050 target of a 50 percent reduction, compared to the 2008 level, in these massive emissions. However, according to Denmark’s Maritime Development Center, while better technical and operational solutions must continue to be pursued…

Unmanned Vehicles Collect Data for Improving Storm ForecastsThe influences of ocean conditions and currents on living environments are now more widely appreciated—from the Earth’s climate and severe weather conditions to fisheries and biodiversity. Sustained and widespread measurements are needed to provide essential clues for understanding the oceans, for effective monitoring of environmental changes, and for helping to clarify the long-term effects of global warming.To meet this challenge, ocean researchers have invented various types of unmanned observing platforms.
