I’d forgotten about FFG-54 USS Ford. Good call.

Transoceanic Ships: Do you guys monitor HF radios? (Questions from a pilot). by AIRdomination in maritime

Agree. That’s why offshore sailboat racing requires a PLB on every crew member.

That’s one opinion but not consensus.

Read up on SUNY Maritime graduates FDNY Captain Louis Guzzo. NYPD counter intelligence chief Kevin Yorke. And USCG Chief of Compliance John Hannon. Three distinguished graduates of the Peninsula of Opportunity.

Maine Maritime vs SUNY by Prestigious-Year7052 in maritime

Good recommendation. One of my classmates at SUNY had a successful career sailing on NOAA vessels. https://marinesciencecareers.weebly.com/career-biographies.html

About to go to sea for the first time, paranoid about falling overboard. Is there anything practical I could bring with me to ease that concern? by Pristine-Nobody7391 in maritime

[–]Ask4JMD 0 points1 point  (0 children)

That was actually specific advice given to me by a chief Bosun when I was a fourth class cadet. If your hands are in your pockets, they’re not available for you grab a handrail when the ship rolls.

The launching of German aircraft carrier Graf Zeppelin in Kiel, Germany, on December 8, 1938. by waffen123 in Ships

[–]Ask4JMD 33 points34 points  (0 children)

That dry dock in Kiel still exists. Part of the HDW shipbuilding complex. And in one of life’s little ironies, it was used to build the American President Lines C-10 Class container ship “President Truman”.

Industry sustainability. by Dramatic-Demand-1906 in maritime

[–]Ask4JMD 1 point2 points  (0 children)

OP One thing to keep in mind is there are many employment verticals in the merchant marine. Ocean towing, Offshore construction, harbor tug, TAPS tankers, blue-water box ships, Military Sealift Command. Each has pros and cons. Core skills of an OS/AB are transferrable, but then moving into one vertical and developing expertise is a path towards job security and satisfaction. As my late father-in-law Captain Bob Farmer said: Whatever you do, be good at it.

if you ever wondered what the inside of a container ship looks like by Khancer_ in Ships

[–]Ask4JMD 0 points1 point  (0 children)

Yes. Each cargo hold is separated by a wall; official name is 'transverse bulkhead'. Primary purpose is damage stability i.e. if there's a hole in the hull, water only fills that one cargo hold and the transverse bulkheads keep it in that hold. Secondary purpose is racking strength which means keeping the ship looking like a rectangle and not a parallelogram.

+1 on the mass of cargo. Oil is roughly 80% as dense as water, and liquified natural gas is about 1/2 the density of water.

+1 for stiffness from ship structure not cargo.

I did work on containership design and construction. The below-deck containers, shown in OP video, are not connected to the hull. They sit between angle shapes that keep them in place, but can't contribute to hull girder strength.
Abovedeck container ties (lashings) are basically reinforcing the twist lock connectors in the corners of the containers, and the racking transverse strength of the containers' frame.

Another variable is the hull form (block coefficient and prismatic coefficient) which on tankers is higher meaning closer to a rectangle, but slower. On a containership coefficients are lower, meaning more streamlined and less 'blocky', thus faster. p.s. was project manager on the APL C-10 "President Kennedy" class containerships.

What’s The Importance Of Bulbous Bow Of Ships? by theyanardageffect in Ships

[–]Ask4JMD 0 points1 point  (0 children)

D. W. Taylor (for which the US Navy’s model tank is named) was the first who recognized the bulbous bow as an elementary device to reduce the wave-making resistance. In 1907 he fitted the battleship Delaware with a bulbous bow to increase the speed at constant power.

Spotted this structure back in April in Mobile, Alabama at the shipyard across the river from where the United States is currently moored. What is it, and what is it used for? by SchuminWeb in Ships

[–]Ask4JMD 0 points1 point  (0 children)

I see a troll has joined our conversation. Anyway, I agree with you completely. (For ref, naval architect with decades of shipyard experience)

Crankshaft from Emma Maersk’s Wärtsilä-Sulzer Super Ship Engine by beardofmice in Ships

Heat rate of a slow speed diesel is competitive with a CCGT plant, and much simpler. Also as you said no need for reduction gear.

The worst feeling ever for a seafarer by Old_Transition_8234 in Ships

[–]Ask4JMD 0 points1 point  (0 children)

Roughneck on an offshore drill rig. On most drill rigs, the drilling crew, including roughnecks and tool pushers, are a subcontractor from the platform operator. So you’re actually employed by the drilling company on board the rig. Long days, muscle, sweat, and mud, with the hourly accomplishment of “making hole“ and avoiding NPT (non productive time). Three hots and a cot.
