Bob,
I have had one of these for a while.
Superb bit of kit, does exactly what it says on the tin.
It can take up to 2 days to fully charge a decent size battery.

Yes, the low charging rate is the only downside. I have a Halford's 'intelligent' charger I bought some years ago. You can select between sealed and vented batteries and car or motorcycle and the charge rate is up to 8 amps before it switches to trickle charging.

CTEK do the battery chargers in numerous sizes and configurations from 0.8 A to 120 A
I was recommended the 3.8 A version by the RAC

Hi I also have a Halfords one as per Colin, works nicely.  I purchased another one to keep our club 5 inch gauge electric loco batteries charged.  Excellent.

Deme Orion 'new design' floating vessel Liebherr crane collapse on first load test.

Video shows boom flipping over completely backwards, over the gantry!   :} :}

True.....  but a bit unusual for a brand new crane to fail at just over half the rated load?!?!!!!!   {:-{

Edit - now appears to be a hook failure .....


"The crane’s twin boom and jib appears to have flipped over the rear while lifting a test load at the Liebherr yard in Rostock. We are told that the incident was caused by the failure of a wire rope during an overload test, but this has not yet been confirmed. The collapse was captured on video which you can see below.

Update:
We have now learnt that it was not a rope that failed, but the hook block - the four leg hook broke free of the neck/shaft. The sudden release of the heavy test load caused the boom to catapult back over the rear of the crane and crumple."

Surprised the crew in the cabin next to where it came to rest I bet, and also surprised there is no footage of the failure, to capture that on the links it had to be filmed during the test and thats not being show - unless you know better  O0

That ship was supposed to be heading north to lift these things which are part a hundred turbine wind farm off the Moray coast.

A couple of years ago they used two other monster heavy lift ships on the Beatrice wind farm, the Stanislav Yudin and the Oleg Strashnov.

I reckon he feels prettty chuffed at being a Colonel, Knighthoods seem to be a bit indiscriminate sometimes.  He might need to get his uniform sorted asap.

Many Naval vessels undergoing major refit have literally scores of oxy-acetylene activities going on, but at the same time the vessels may have their Fire Suppression Systems [FSS] pumps out of operation


Warships do not have hull length manifold supply of any flammable materials/gases.....seeing pockets of fire along 2/3 the length of the vessel suggests the fires/explosions were not localised?


Such refit activities I have witnessed on RAN vessels were always complimented with numerous 4" shore side standard canvas fires hoses connected into the vessels FSS and continuously pressurised, so if any Fire sensor was activated, the on-board system would be operational


Again, in Australian dockyards, every oxy-acetylene activity on an Australian vessel is complete with a Fire Watcher.........

According to one source at San Diego on one of the other ships moored along side they think it was a munition that exploded as it was being lowered below the flight deck. By sounds of things the ship is a write off.

According to the US Navy it was a 45 gallon drum of "volatile liquid" used for cleaning tools. I wonder if a tool was having a crafty smoke net to the drum? Nearly said fag but being a US ship.

 :D ........


For obvious reasons, volatile US MIL-Spec fluids are supplied to surface vessels in 5 US Gallon drums...this includes hydraulic fluids
Aviation Gas [kleen kerosene] is bulk supply..as is Gas Turbine fuel [not as kleen Kerosene] and diesel oil....


The video footage shows fire/smoke in 3 distinct areas ...say 100 ft apart  :o


Big Boss in the White House will be in charge of the next comments to the Media...........we may never hear the final Reports from Defence at the conclusion of the Investigations sometime in 2024'ish.....


Suggesting anything more would place me on shaky ground with MBM Rules

Certainly looks like the ship will be a total write off.

pfff....every fire watcher I found so far was usually more occupied with facefarce or candy crush somehow on their phone.  These guys were usually not observed wearing lace-up boots either.

We did have almost an incident once where the main gas line to the vessel was apparently smouldering and shut us down.  Shipyard fire chief for the job insisted it was OK, then I remember my project boss showing me the charred fire arrestor for the full vessel, after he threw it on the table earlier in the HSE meeting, and strangely, the yard fire chief (apparently a well known fire chief for the area), was never mentioned or seen again.

...Well understood the most likely chance a vessel has of catching fire is in port, or undergoing maintenence for fairly obvious reasons.  A previous company I worked or spent a fortune doing life extension of their xxx vessel, had a fire in last few weeks which ripped through and cost something like upwards of 2x the damage of the life extension.

A company I visited in the states years ago had an airborne content of hazardous chemicals way over and above what any visitor should be subject to (nevermind workers) but rules change these days, they declared 2 fires based on not electrically earthing a 45gal chemical drum each time before opening and de-canting before the flame spread to other areas.  This is why companies use Scully type systems now.

All RAN Officers and Seaman are trained in fire fighting and fire control........this is the same training irrespective of related main Trade activity be it ET [Electrical] ME [Mechanical] MP [Propulsion] and so on for other speciality Trades   


During the RAN drydock refit work at Fleet Base, Garden Island NSW, oxy-acetylene activities were carried out by Mechanical Trades being Dockyard employees. The Fire Watcher role was carried out by the Ships Seaman categories dependent on the location of the work

The philosophy employed was...'this is your ship, don't let Dockies burn it <*<


I cannot comment on Naval work conducted by other external providers [HMAS Bundaberg incident - destruction by fire]
