In July, the IMO released the fourth version of “Reduction of GHG Emissions from Ships.” At 577 pages, it’s hard to overstate the report’s scope and detail. The big picture: Total shipping emissions rose from 977 million tons in 2012 to 1.07 billion tons in 2018, a 9.6 percent increase, mostly carbon dioxide (CO2). The industry’s share of global greenhouse gas emissions increased from 2.76 percent in 2012 to 2.89 percent in 2018.
Maritime carbon intensity improved between 2012 and 2018, the IMO report stated. However, the reduction has not been constant, and it has slowed since 2015.
One of the most troubling aspects of the report is the increase in methane emissions. Methane, the primary component of natural gas, has 86 times the climate impact of CO2 over a 20-year period, according to the Intergovernmental Panel on Climate Change. In ships, the use of liquefied natural gas (LNG) increased by about 30 percent from 2012 to 2018. During that same time, methane emissions increased by more than 150 percent.

Piracy edges closer to home with wave of raids in southern Gulf
In the brief cellphone video recorded by a crewmember on the offshore supply vessel (OSV) Remas, the pirates walk back and forth on the deck of the ship, clenching their guns and using them to point as they order around the crew. Their faces are draped in clothing and bandanas.

IMO emissions report raises new concerns about methane slip
A recent report from the International Maritime Organization (IMO) reveals that global shipping emissions increased nearly 10 percent from 2012 to 2018, with the industry facing a growing challenge concerning methane slip.
Bay State brothers find industry niche by making old into new
Zero non-conformities is what you want to hear when the U.S. Coast Guard inspects your tugboat. Once you’ve prepared your vessel, the inspectors come aboard to peruse your paperwork. They ask you pointed questions, to which they expect straightforward answers. Perusal completed, they then scrutinize all of the related safety systems, from bilge to antennas — even the ship’s bell.

Analysis points to faulty loading, low ballast in Golden Ray rollover
While the salvage of the sunken vehicle carrier Golden Ray has been delayed for months due to COVID-19 and the hurricane season, analysis by the U.S. Coast Guard has determined a possible cause for the rollover: a combination of vehicles placed too high on the ship’s decks, and not enough ballast water gave the placement of the cargo.
Seastreak newcomer pushing through dip in demand
Two years ago, Seastreak LLC took delivery of Seastreak Commodore, a 600-passenger fast ferry, from Gulf Craft of Franklin, La. Designed by Australia-based Incat Crowther, the vessel is the largest of its kind in the United States and was built to meet the burgeoning demand for service in the New York-New Jersey market.
New year in a new world: Navigating COVID's maritime realities
In a matter of days, the decorative time balls will drop, “Auld Lang Syne” will fill the air, and ships at anchor will sound their horns as the world welcomes in the new year.
Advanced props, rudders provide new efficiencies below the waterline
It took a decade or two from the invention of the marine propeller in the 19th century for the technology to become widely accepted. Thereafter, adoption has been nearly universal, but progress toward improved efficiencies has come in fits and starts.
