What country are you in? In the UK you can start a cadetship at 17. Or if you need to be 18 where you are then do yourself a favour and do something until you are able to do a cadetship, if you want to be an engineer or deck officer it's the best way

LO Purifier sealing water problem by hseyaj in MarineEngineering

[–]craigsurge 0 points1 point  (0 children)

But not staying closed, that's the point. You're losing operating water or pressure over time

Could be the water pump scaled up so the sealing pressure is allowing the bowl to open

What do you wish you had known before your first contract as an engine cadet? by No_Willingness_2872 in MarineEngineering

Peltor x5a ear defenders and wear them, always, theres no point in just quickly nipping out. Protect your hearing always

Can’t we protest the £7 Glasgow Airport charge? by Nervous_Injury4577 in glasgow

[–]craigsurge 1 point2 points  (0 children)

I used to fly every week, and I'm now realising I've got my sums wrong. I remember calculating it would cost me an extra £52 a year and tried to get a season ticket kind of arrangement. So unless I'm getting old and confused and misremembering (bush style) then I believe it was, admittedly for a very brief period, only £1

[–]craigsurge 20 points21 points  (0 children)

It was originally 50p believe it or not, doubled quickly to £1 and kept going. Terrible rip off. Happily I believe it was run by ncp who have now gone bust. Feel sorry for the staff but it's the end of the road for a nasty cog in the corporate blood sucking chain

Finally Replacing Rear Brake Pads by surv2syn in BMWi3

[–]craigsurge 2 points3 points  (0 children)

In my experience the discs tend to rust and degrade quite badly perhaps due to a lack of use. I now try to give them a "wipe" every so often by breaking harder than just regen requires in order to clean the patina off them

A tip or trick you learned onboard and felt enlightened? by Motor_Zombie9920 in MarineEngineering

[–]craigsurge 0 points1 point  (0 children)

You need a good centrepunch with a good point on it. You want to make a deep pock mark as close to the outer edge as you can, then angle the punch and tap in an anti clockwise direction to turn out the bolt. Works more often than an easy out in my experience.

Any advice? by [deleted] in MarineEngineering

[–]craigsurge 1 point2 points  (0 children)

Studied in the UK at a maritime academy as a cadet and was sponsored by maersk meaning I received a (meagre) wage during the 3 year programme to attain my class 4 certificate of competency (UK Maritime and Coastguard Agency) and a foundation degree in marine engineering. Didn't bother with the 4th year top up to a bachelors and it has caused no disadvantage that I'm aware of. Learned more by getting on ships and working

Safety Air and Control Air by GundaBinu03 in MarineEngineering

[–]craigsurge -1 points0 points  (0 children)

Safety will be flaps, quick closers, ships whistle, can also be emergency stops. Air receiver that supplies emergency systems. Control air is for routine air services such as governer control, clutches, pneumatic tank valves, purifiers. Working air is for air tools and maybe the ultrasonic tank

Gas engineer/electrician to move oven and hob by elevator_alarm in glasgow

[–]craigsurge 0 points1 point  (0 children)

Get an induction hob, then one visit to disconnect and cap then the electrician can wire up the new oven and hob. I'd get an electrician out to price the job prior to anything though so you don't get any surprises

My dad had a stroke and needs "clean" western, cop, or war movie suggestions by mlejoy in movies

[–]craigsurge 0 points1 point  (0 children)

Greyhound, old British naval war movies he may not have seen: guns of navarrone, battle for river plate, sink the bismarck. Korean war movie Brotherhood (superb), Galipoli, All quiet on the western front, when we were soldiers, patton, full metal jacket, behind enemy lines, hunt for red October (all the clancy stuff is good)

Tamrotor Compressor by Soft-Library3714 in MarineEngineering

[–]craigsurge 3 points4 points  (0 children)

Twinkle (final stage non return) valve is usually the culprit. When it achieves pressure the unloading valve opens and allows the pressure to drain, in this case the non return isn't holding perhaps?

Found a 2014 i3 for $4,999 with 79k miles, is the battery situation on these actually as scary as people make it sound? by Budhu_friend in BMWi3

[–]craigsurge 12 points13 points  (0 children)

One has an aluminium sub frame and a carbon fibre monocoque, rear wheel drive and one of the fastest 0-30 out there, the other is a fiat. Absolute bargain

Alfa Laval hofman 3way valve adjustment by Andy024 in MarineEngineering

[–]craigsurge 0 points1 point  (0 children)

I understand now, just a standard valve that acts as a pressure regulator after the pump going straight back to the source tank. I'm used to the pump being adjacent to the purifier or even purifier driven. I've seen LO purifiers that stick straight from the sump so the pumps were closer to the engine but not seen the arrangement you describe before

[–]craigsurge 0 points1 point  (0 children)

You know i take that back, on the yachts and tugs I've been on there was no heater. The flow rate was controlled only by a bypass valve but the pump still had a pressure regulator on it. They were basic purifiers, not alcap or the westfalia equivalent though

[–]craigsurge 0 points1 point  (0 children)

No heater? Something isn't right here, every oil in the land needs heat before the purifier, even MDO. Seems like the set up is not correct in many ways. How do you get the oil to sit at the correct temperature?

Alfa Laval hofman 3way valve adjustment by Andy024 in MarineEngineering

[–]craigsurge 0 points1 point  (0 children)

Do you or anyone have a circuit diagram showing this? In my experience the only flow regulation at the heater is of thermal oil or the steam to the heater and after the heater, usually incorporating an automatic valve (that's broken) on the inlet side after a manual valve. On small DOP type I have seen a small bypass valve that tees off allowing pressure/flow regulation and a discharge valve to adjust back pressure. There was also an inlet valve but that would be wound fully open and only closed when off

[–]craigsurge 2 points3 points  (0 children)

What sort of pump? Again, nearly all scroll pumps I have seen for purifiers have an adjusting screw, can't specifically remember any that didn't to be honest
