You are on the right lines, look closely at the old mooring rope securing the crane hook to the Deck.
How do you think it gets tightened to the point where that heavy old rope is as flattened as it is?

No JK, the pictures are of a cargo crane, and the tower supporting the crutch for it and the platform where the crane hook is secured when stowed.

If there was a major crankcase explosion it is likely that the cooling water system was damaged and leaking into the hot engine or fire, if there was a fire, generating large quantities of steam (white smoke). I have seen this on 2 ships where we had the main engine piston seize and crack the liner,...

I have been reading this with interest and so far I have not contributed due to my total lack of experience on large passenger ships like this. However, I did have a problem with a clapped out old tanker which had twin V12 Pielsticks clutched into a common gearbox & CPP prop. We were happilly st...

For all the frustrated viewers, the pictures are now securely attached!

Hi, As previously advised put the boiler on gas oil or diesel oil firing rather than HFO and flush the fuel system through. GIVE THE BOILER A GOOD TOP AND BOTTOM BLOW DOWN. If it is a multi boiler steam plant, and you are going to continue to use steam, you will gradually throttle in the main steam ...

They say that every picture tells a story. In the following triptychet each picture tells a short story that combines with the others to tell the full story. Do these pictures whisper to you like grains of sand, softly sussurating across the dunes in the Sea breeze, or do they bellow at you in the s...

Good luck turbo!!!

Hi and welcome to the site, I think JK's links pretty well cover it. I would emphasise that as you tighten up you should always keep checking that the BE is still floating freely fore and aft on the crankshaft. I had a Polish 3/E overhauling a generator unit a few years ago, before he started you co...

I used to despair on some ships, where you saw little baked bean tins or whatever, carefully wired up underneath a small leak to catch the drips. It was so much more work than taking a shifter out of your pocket and nipping up the leaking gland!!! The best was when the first tin overflowed, and then...

d it P1000499.JPG I have just joined a "new ship", to me anyway. I thought that this picture might raise a smile. It is a 25/30 bar discharge line from the main starting air compressor. There is a slight leak of air and condensate, and some one thought silicon sealant was just the product ...

You have to be very careful with O rings, lube them with something, but if you are making potable water it should be a food grade lubricant. Don't freak out,vegetable oil/ cooking oil will do at a pinch. The design always appeared flawed to me, a single O ring between high pressure salt water and lo...

With regard to wiring up these electronic units, the signal cables must be shielded with copper braid on the outside (Not to be confused with armoured!). To shield the signal the Braid must be properly Earthed, BUT ONLY AT ONE END. The other end of the Braiding should be left insulated. If the Braid...
