Following on from my previous post giving view from ships bridge and relation to seeing yachts etc.
I have just visited another vessel and had time to discuss with Officers and Master various topics that I am sure would interest many here.
First of all interaction with Yachts .... this vessel is 100,000 ton Tanker again .. but different - traditional 90's design .... with retro-fit of later technology.
3 Data readout GPS
ECDIS Charting system
X Band and S Band full Anti-Collision / AIS capability
"Paper Chart" folios full - covering vessels expected trading area.
I took opportunity to "photo" data / diagrams displayed on bridge - to inform Pilots and also as reference when needed for Officers etc.
It was interesting that this vessel actually displayed the "blind-vision" table on the bulkhead .... : >
Now onto manoeuvring data ... a lot of posts have been made over the years about ships like this taking 3 miles to stop etc. and so on .... well here is the real data as actually measured on sea trials ......
(please note that I have to remove id of vessel etc. as this is commercial information)
Now in discussion with the Master and Officers - I concentrated on 2 areas .... meeting Yachts at sea / restricted waters .... and paper vs ECDIS.
As to meeting yachts ... they said that generally they had no problem and if location was without restriction - they had no problem to turn and give way if req'd. BUT they emphasised that yachts have to learn that on ship - 1/2 mile is far too close .... A point that surprised me was the Master and officers mentioned they had an incident with a number of Mobo's in a group ... 2 or 3 MOBO's were moving along and were not a problem ... (this is Solent and seriously restricted for vessels like this) .... then without warning first one MOBO then others opened throttles .. cut across ships bow and disappeared from view "under the bow" ..... In the Masters words ..... "Word filtered" !! He added a comment at the end .... which I feel summed it up .... "there's room for all on the water ... just pay attention to whats around and also others limits .... cut it too fine and it's the last time you do ..."
Onto Charting .... the Second Officer and Master played biggest part in this of course ..... the ECDIS system they had was Transas Maritime on dedicated PC system. The charting being Vector based. Updates to Vector layers / details were received via CD disk at approx. 2 week intervals. It was admitted that the ECDIS often lagged behind the paper charts in corrections. The Paper Charts were corrected by supply of tracings from Chart agency. The Paper Charts were the registered Main Chart System of the vessel.
What was interesting was that the vessel had a change of chart system in the past - based on officers request .... removal of ARC's Raster system and replaced by full Vector. I was surprised as this is not a cheap exercise .... but the Officers were very pleased and were unanimous on this vessel that they would prefer Vector to Raster.
Ok onto the ship itself ....
LOA : 246.8m Breadth : 42.0m Depth : 21.3m Summer Load Draft : 14.798m Gross Tonnage : 58,118 T Nett Tonnage : 31,909 T Light Ship : 16,657 T Summer Deadweight : 107,215 T at Displacement average 123,872 T
Air drafts Ford Mast 36.45m Aft Main Mast : 48.67m
Draft aft to fully immerse propellor req'd = 8.27m
Main Engine : 18,395 HP driving 4 blade fixed propellor of 7.2m diameter. Service speed designed 14.75 kts. Range at full speed on full fuel : 22900 nm
Anchors : Admiralty Cast (AC-14 Stockless) 2. Each at 10 T with 13 schackles of chain each.
Generators : 3 sets at 750 Kw each. Capable of simultaneous or individual coupling.
Cargo Pumps - 3 Main pumps each capable of 2,500 cu.m each per hour and deliver to 10 bar backpressure.
Final word .... If there is any question that any of YOU lot on the forums would like answered by Ships Officers / Masters I meet ... then please PM me and I'll see what I can do ...
I hope I can find another avenue / data report to post later given another opportunity ......
