  Created 2016                                                                   FWG and Vacuum It is a common sight to see a Fresh water Generator coated with   Grease.Many   optimistic Engineers believe that   one can apply grease on SUSPECTED areas to prevent AIR INGRESS into the shell and thus improve the Vacuum and the overall production. Many would dismiss this as MISPLACED optimism.Just as a determined    sailor can find his way to the nearest bar in a foreign port ,so does AIR find its way to reach a place where there is Vacuum . Best methods to make a FWG , AIR TIGHT – Arrange to pressurize the FWG shell with water-ONLY...

Original Creation - 20-1-2014   Operating a ship is all about TEAM WORK and it works best with Transparency and Openness Anything behind closed doors promotes suspicion, rumor- mongering and guessing games. Typical secrecies occasionally observed on board would be senior operational level Engineers and Officers withholding information from juniors just to protect their SUPERIORITY and importance.. -- Juniors Officers/ Engineers withholding operational level defects observed during watch keeping from their seniors, for whatever the cause or FEAR. -- Information on Some special TRICKS involved with operating/ starting certain equipment’s may often be held up ones sleeve to gain importance as an EXPERT. But withholding information about these tricks may  not only spoil the TEAMWORK environment which is required but may also backfire at the person practicing these methods. Nobody wants to be woken up at 0200 hrs to rectify a fault in Purifier even though one takes pride ...

  Original creation :25/8/2011 Boiler Safety There are three things which are required for successful firing of Boiler. Admission of fuel –Atomized or as per design (including correct viscosity/temperature etc) Sufficient Air to ensure Combustion— Both above are in a proper Ratio (stoichiometric Ratio) and designed to mix   as per design. Ignition to kick start the Firing. The above happen at a particular sequence with meticulously calculated time intervals The entire process is Automated by Boiler Misfiring of a Boiler –results when one of the above gets disturbed. When there is a failure of complete of Fuel admission – Not much Harm might occur –except for the Boiler Not Firing. However if there is a Failure of admission of AIR or IGNITION , fuel would be inserted into the boiler furnace which eventually never could be ignited .So Accumulation of Fuel Takes place which may leads to Furnace explosion when an attempt is made to...
