Years ago I was told that running costs, parts, labour & L.O. for a medium speed were double the costs of a slow speed of similar power. The running costs of a high speed engine are double those of a medium speed.
I think, as ball park figures, this still holds true.

The sad truth is that it is very hard to change peoples attitudes. I am Chief Engineer on board a ship with Multi National crew. We have the SMS, permits to work, risk assessments etc in place. I am the only Brit, but we have a Canadian and a Panamanian everyone else is from Eastern Europe. However,...

Last I heard was that there were suspicions the ship was carrying the Russina equivalent of Patriot ground to air missile batterries to protect Iranian Nuclear Installations.

I think JK has asked the crucial question here, if he cut an inch of the end of the poker gauge, all is clear.

The total of the top and bottom readings should stay constant. (There is no wear of the shaft at the point readings are taken) In water reading total 165.4 original total 113.8 difference 51.6 or 25.8 per reading. The difference between top & bottom readings should change as the stern tube beari...

Wild guess, and it is only that, worn feedback potentiometers on the fuel rack. When the engine rolls the feedback values jump erratically.

All I can say is if you want precise limits for your particular engine, and your particular application, the best option is to email the engine maker's service department.

Before I joined one ship the crew were putting oil in the fridge compressor every day, they then orderd and fitted a new compressor (complete with oil seperator) and had to drain oil out every day, until the system stabilised with a constant amount of oil in the circulating gas. I think the only pro...

Good luck with the job hunting, a couple of ideas no one else has mentioned, there used to be jobs advertised in the UK shipping newspapers for ship's engineers to operate & maintain breweries and sugar refineries. A sugar refinery basically has big rollers to crush the cane, water pumps to wash...

With a traditional mechanical/hydraulic Governor, (Woodward) each governor would be adjusted to maintain the engines at constant RPM with a slight "Droop". (i.e. the RPM will drop off slightly as load increases, preferably in an identical way on all engines that can be run in parrellel, to...

I can envisage 2 different scenarios:- A) 1) I suspect the oiler found that the bunker tank levels had gone up. 2) When the overflow tank went into alarm, ideally all the bunker tanks should have been sounded in order to determine where the oil came from, however that is the ideal answer in an exam,...

If the air is this cold then then the charge air "cooler" will be heating the charge air. We normally get surging and barking when the differential pressure on the the turbine compressor excedes the design limit of the compressor and the air flows first stalls, then momentarily reverses. W...

All in all it was a very interesting trip.......but not one I wanted to repeat. I joined the ship in Brazil, it had come across the Atlantic with 3 days diesel for the alternators, OK so long as the shaft alternator kept running, however, when they arrived in Port and were told to anchor for a week ...

You would think someone would have noticed something but they weren't the brightest..... One day I went down the engine room and saw that the running D/A had no oil in the sight glass for the turbo. I tried to get the watchkeeper to change over the D/As but he said he couldn't do that. I then tried ...

I agree with you, I think that if you don't have distilled water for operating the purifiers then it is better to fit water softeners. One alternative I have seen, where the operating water is supplied from open tanks, is to dose them daily with a few milli litres of Evaperator treatment, that will ...
