Things are not as simple as you believe in trying to determine the effect of motions on FPSO vessels. Trying to give you a crash course in ship...
IIRC, SOLAS specifies that a double bottom be fitted to an extent as far as practicable. While having a full DB is preferred, I have done...
Well, the US Govt. uses Wartsila jet drives for the JHSV high-speed, shallow draft transports currently being built for the US Army....

Several years ago, I was involved on a similar project where the owner built an aluminum crewboat approx. 65 m long which was powered by water...
It all depends on what the hull is doing. 100 kPa sounds high, but it's roughly atmospheric pressure at sea level. If you take a speed boat and...
The current SOLAS damage stability method is indeed referred to as "probabilistic damage stability", as can be seen in this publication from...
The correct term is "probabilistic damage stability".
The display should read 'Length' instead of 'Lenght'.
Hydrofoils have been around more than 100 years, starting with experimental craft built by Thornycroft. Alexander Graham Bell also experimented...
He's gotta say that; in the Kingdom, they chop off heads for far less worse things than a crane collapse which kills scores of people.
Fell over, or was pushed over?
Maybe they make up what they lack in experience with copious amounts of "Dutch courage". :D
IMO, this casualty was imminently preventable, even without employing the services of a company like Mammoet. A reasonably qualified naval...
The sad thing is the land guys thought they could move their crane operations onto a floating barge without worrying about the consequences. Even...
What you say is true, and there are barges which are designed with ballast systems that can be flooded or emptied to counterballast a crane....
The point is, when using water ballast, it's a good idea to press the tanks full and not have any tanks partially filled, where a free surface is...
Free surface in tanks does have the effect of reducing the stability of the barge. Road cranes can be used safely on pontoons, but you can't be...
