Oh no, she's a white supremacist.

 

This kind of reminded me of the gal on the Deepwater Horizon.  She was a young licensed first mate I believe and was charged with "steering" the rig.  Some interesting occupations for merchant marine officers.

On the subject of opposed-piston diesel engines, this came across my google feed.  https://www.autoweek.com/news/technology/a36068845/opposed-piston-engines/

Apparently they are very efficient, but pretty heavy.  A company is designing them for construction by Cummins and the usual diesel suspects.

Every now and then google's spyware algorithms serve up something interesting.

They're two-strokes so it's hard to make them run as clean as your std. otto-cycle engine. I would imagine wt. per hp or whatever to be lower as they have no valvetrain, but also produce power every stroke (beavis.gif). Probably why two stroke diesels are popular marine power-plants but you don't see them on over-the-road applications anymore (light for the power but dirty).

 

Looks like from the article they are using modern fluid dynamics modeling, or whatever, to develop a clean two-stroke:

 

Quote

“Up until very recently (due to work by us, like what you saw yesterday), nearly everyone believed that two-stroke engines could not meet modern on-highway emissions standards,” Fromm said. “This is because the two-stroke cycle is very complicated—the gas exchange and combustion operate in one continuous event. You have to optimize the system as a whole. Before supercomputers and sophisticated chemically reactive computational fluid dynamics, optimization was done by intuition and trial and error. As a result, all two-stroke engines were dropped from regulated markets.”

time is a fucking flat circle. it feels like the last 3 years is one giant fucking shittastic Groundhog Day.

A fucking year to the month, Ever Given's cousin ship, Ever Forward (insert joke), is stuck in Chesapeake Bay. Someone fucking reboot the timeline starting over in 2019.

Good news however.

"But the smaller ship’s grounding is unlikely to cause as much trouble as last year’s crisis. The Ever Given’s plight caused headaches for more than 400 waiting vessels, costing global trade $6bn to $10bn a day, according to a study. The Ever Forward’s grounding, on the other hand, was “not preventing other ships from transiting to the Port of Baltimore”, said William P Doyle, the executive director of the Maryland Port Association, to Bloomberg in a statement on Monday. “Efforts have been under way since last night to try and free the ship and will continue today.”"

Ever stuck: Suez container ship’s cousin runs aground in US harbor

The 334-metre Ever Forward ran into trouble in the Chesapeake Bay, a year to the month after its cousin blocked the canal in Egypt

A year to the month after the Ever Given blocked the Suez canal for a week – prompting global fascination and countless memes – the container ship’s cousin has run aground in the Chesapeake Bay.

Officials are now scrambling to refloat that container ship, ironically named the Ever Forward, after it got stuck on Sunday night as it tried to head from the Port of Baltimore to Norfolk, Virginia, Bloomberg reported.

The US Coast Guard said it did not know what had caused the stranding, which did not lead to any injuries or harm the vessel, according to CBS Baltimore.

Like the 400-metre Ever Given, the 334-metre Ever Forward belongs to the Taiwan-based Evergreen Marine Corp.

But the smaller ship’s grounding is unlikely to cause as much trouble as last year’s crisis. The Ever Given’s plight caused headaches for more than 400 waiting vessels, costing global trade $6bn to $10bn a day, according to a study. The Ever Forward’s grounding, on the other hand, was “not preventing other ships from transiting to the Port of Baltimore”, said William P Doyle, the executive director of the Maryland Port Association, to Bloomberg in a statement on Monday. “Efforts have been under way since last night to try and free the ship and will continue today.”

Other ships in the area were told to slow down and use a one-way traffic pattern.

The ship needs water at least 43ft deep to move, but it was stuck in an area that was just 25ft deep. It was not clear when it might be freed. “Everything like this is kind of its own beast,” the coastguard petty officer Steven Lehmann told the Baltimore Sun.

The effort to rescue the Ever Given, which weighs 220,000 metric tons, required dredging 30,000 cubic meters of sand, with the help of 13 tugboats and a rising tide. The vessel was trapped from 23 to 29 March.

Since then, however, the Ever Given has managed to get through the canal without getting stuck. The maritime app Marine Traffic showed it in the Red Sea on Monday night, headed toward the Suez once again.
