Interview Series: A look at cargo holds – Part 1

Aug 09, 2021

Today we begin hearing an interview I did recently with Dan Sealy, a cargo hold inspector who goes down into the holds of bulk carriers anchored off Astoria in the Columbia River.

Part of his job is to check whether holds are in suitable condition to take on cargo. His work is part of the federal government’s regulation of cargoes shipped from U.S. ports.

Today in Part 1, we’ll hear a bit from Dan about the agency he works for and more about his job.

What if tug loses power while it’s towing a barge?

Jul 23, 2021

I got a listener question from someone watching a tug go by, who asked what tug crews do if a tugboat loses power while it’s towing a barge? For an answer, I consulted my friend Phil Martin, a retired tug captain who lives on the Long Beach Peninsula. He told me there are no hard and fast rules in such an emergency – depending on conditions you do different things. But it’s certainly a time when tug captains must draw on all their expertise in a critical situation.

Plane crash debris prompts USCG search and rescue effort

Jul 13, 2021

USCG crews on the Columbia River spent part of Monday searching for survivors of a plane crash after a Good Samaritan reported wreckage near Kalama. The debris turned out to be from a crash last March. We’ll talk about how the Coast Guard handles rescues, and how you can prevent an accidental false alarm emergency call.

Liquefaction: a dangeous twist of physics that makes some cargoes dangerous

Jul 12, 2021

Today we’ll talk about liquefaction: the tendency of some cargoes that are solid (certain kinds of mineral ores), but can behave like liquids in a cargo hold under certain conditions. It’s a dangeous consequence of basic physics and how cargoes are loaded and stored. If that happens, it’s not a ship you want to be on.

Update on river cruises: what passengers should expect

Jul 06, 2021

As river cruises nationwide open up again, there are some caveats passengers will have to follow. The most important rule of thumb is that rules are different in different states and you need to be ready to adapt if you go.

A bit about that Heat Dome and how it relates to the Pacific Ocean

Jun 29, 2021

What’s wth this “heat dome” situation we’ve been experiencing in the Pacific Northwest, in areas that are normally cool? We’ll talk today about what causes a heat dome to occur. Part of it has to do with ocean temperatures in the Pacific.
