Re: Marine Refrigeration

Referring back to my unanswered query on the refrigeration subject. Well I suppose that in order to answer my own question concerning Big Pete's write up re NH3 etc. and to remember when NH3 ruled you have to perhaps be of a certain age and maybe forthcoming folk who do indeed remember operating NH3...

It's a BOB machine, it's not a ship to me.
BOB?
Bolt on Bar.

Re: Marine Refrigeration

Well that's a lot in anyone's book to take on board. Very fond memories of in particular NH3 As I wrote previously of cracking off the gland nuts on the HP discharge side of the compressor for a sniff to instantly cure that hangover. Worked every time and almost encouraged you to drink more ale back...

Re: Celebrity Edge Rollout

The very latest in top heavy Tupperware dishes. The moving " raft " type job is a large bar/ restaurant bolted / welded onto the Stb. Side of the ship amidships which climbs up and down the whole area of 13 decks from the waterline up. The Magic Carpet its called. This obviously is some de...

Re: TheNavalArch - Ship Energy Efficiency Design Index (EEDI) Calculator

Just had a manufacturers circular arrived, new software must be downloaded ( at a cost ) by May 2018 to all certified smokemeters over here as they are struggling to measure some of the newer CR emissions outputs. Heading towards that target of just compressed air discharge to atmosphere methinks. D...

Re: main bearing measuring tool calibration

Go or no go gauges we used to call them. Precision ground tool steel or similar. Same as precision ground tool steel used for checking micrometers and verniers etc., should be one in the kit, without it not much point in performing the test. Need to be zeroed before taking any run out measurements. ...

Re: TheNavalArch - Ship Energy Efficiency Design Index (EEDI) Calculator

Agreed Big Pete 100% Same as times given for engine/ gearboxes etc etc overhauls major /minor ones. All times quoted are referred to sometimes by owner/operators? This is blatantly an attempt to reduce repair costing. What they conveniently forget is all times quoted are for new engines straight off...

Re: Advance timing for fuel pump

One has to ask the question, How are you going to calibrate the pump by adjusting the helix's quadrants without a test bench? How are you going to phase the pump without a test bench? I am assuming this to be an inline pump? Engine could be all over the place without performing the setting up of the...

Re: TheNavalArch - Ship Energy Efficiency Design Index (EEDI) Calculator

I read your publication with interest but are all your calculations of a theoretical nature solely? Are you actually performing smoke emission testing physically to compare the supposedly applied formulae that you are using? If so what's the varying differential factor or is it a constant? Are you u...

Re: Marine Engineering - Practical Tips & Tricks

My own experiences has been that is normally the case in HFO systems but not always so in the case of LFO installation. In the case scenario concerning pre CR set ups the drawing in of air particularly from the LP ( or liftpump ) to the fuel tank / lines / sight glasses/ filter / heaters set ups can...

Re: Common Rail Engine 48/60 cr

Well I reckon these engines are now mysteriously running on all cyls. no problem or sheeted down, parked up on the quay awaiting the wrath of the Canadian winter. Do hope Top Dead Centre is firing on all cyls. and the MAN MUG hitman is not in town. Another gap in my pea sized brain library on this o...

Struggling with the necessary formulae required to comprehend your opening lines, seems to me you have been hull down since 2003 gradually dropping down over the horizon.

Re: Merlyn Birthday

JJ, You're catching me up rapidly though. I worked that out without referral to Reeds/ calculus dx/dy etc. So far, to date I've managed to duck piston/ Liner change/ crank grind and heads overhauls and would still appear to be running on all six. However your date with those golf clubs is much close...
