Re: What to Do ? Fire on the ship while in port.

I remember reading about that at the time " C. Y. Tung" was asked a lot of questions, ("Sea Wise " was a pun on C. Y.) I don't think he ever gave answers though!

Re: What to Do ? Fire on the ship while in port.

I agree with D. Winsor, the Master is always responsible if the ship is operational. If it is laid up, unmanned or with a skeleton crew, I think I would be straight down the gangway if the natives were friendly, however, in some Countries, and with some ship owners you would not want to rely on some...

Re: Wireless Shore Power

I should imagine that something similar to the chickasan oil loading connection could be used for the electric power connection and give Metal to metal contact of the Primary and Secondaries, with electro magnets locating the windings together. I have long thought that winches mounted on the key wit...

Re: Wireless Shore Power

The article is only talking about wireless charging, not magnetic mooring and does specifically mention that the system will work "Efficiently" with up to 50 cm air gap between the ships coil and the shore side one, so in this case I think conventional mooring lines will be used to secure ...

Re: Wireless Shore Power

It sounds just like charging an Electric Tooth brush,Primary winding of the Transformer ashore and the Secondary on the ship. I assume that if the shore power failed the Emergency Generator would kick in within 40 seconds as required by SOLAS, and if one the main generators was left in Auto on the P...

Re: Back to the age of sail?

I sailed with a guy who was Chief Engineer on one of the Windstar ships, he said it was hell, the PR people planned the routes so that the ship never had a favourable wind and to make the schedule they ran the engines all the time, and never used the sails. Despite the Master and Chief both telling ...

Wireless Shore Power

An interesting article here about "wireless" shore power connections for Electric ferries.

There is a replacement engine out, maybe it would be easier to re engine?

Re: Autonomous Ships

I remember 30 years ago the Japanese Governmant was testing an unmanned ship in the Sea of Japan. Wartsilla recently did trials of remotely controlling a PSV at Sea, off the Scottish Coast for several hours in DP and normal steaming mode, the ship, Highland Guardian, Gulfmark Offshore, still had a f...

Re: Engine performance in varying ambient temperatures

I think the latest generation of engines with precise control of charge air pressure through 2 stage turbo charging with waste gates to precisely control charge air pressure and 2 stage charge air coolers to precisely control charge air temperature can almost completely compensate for changes in amb...

Re: Hurricanes

Thanks Jolly Jack for the input, Hurricanes happen every year and even rich sophisticated countries like the USA have problems dealing with them, smaller Countries have no chance on their own. Working for Norwegian Companies I found that they shared a pool of spare parts, in case of major failures, ...

Re: Engine performance in varying ambient temperatures

Hi J-N, The Old way was to calculate Indicated Horsepower, by using a mechanical indicator card, this worked like a recording barograph to record cylinder pressure for each individual cylinder, and the drum was rotated by a piece of string linked to the camshaft so that the Indicator card drew a gra...
