28092011(Brainstorming)

Projection & actual

We started doing small craft building with brainstorming about Mark’s dory. We have not planned yet, but overall it has to take 5 weeks (15 days – 75 man hours). Starting from saying LOA(3.6m), we thought about what we needs to plan, construct and maintenance. Don, who was a real boat owner of the sister dory we are going to make, pop by our classroom and tell something like feedback that he want us to know. By the way, the program ‘Smart notebook’ is quite a good one for brainstorming and re-organising information.

- runners (Chris prefers to have two runners, because they help keep standing when a boat come out of water)

- planking

- rowlock chock

- filling

- housekeeping

- comiclife (a program for making stuffs into comic)

- team contract

- nesting

- fussy

- mahara (e-portfolio program)

- time lapse

28092011(day 3 – day skipper)

This morning, we had a review about what we learned this week and did plotting a course on the chart for Auckland Harbour coming in. I was confused to the depth with number on the chart, because didn’t know where the standard point of depth is. It was in the book though. Chart datum is it. Chris said that it is good to go fishing just after new moon. Tidal stream is faster between high tide and low tide.

- State of tide

- Dawning

- Midday

- Setting

27092011(day 2 - Day skipper)

We have left only the next week this term. Today, we had the second day of day skipper. It is mostly new for me that we learned. Lance and Andrew looks to be reasonably familiar with those terms and knowledge. Theoretical class is more difficult than having practical ones but I have to challenge it. I will look deeply into the book this weekend.

terms

- Underwater spout (a symbol looks like a fountain, representing underwater spout)

- overfall (like a cliff that got suddenly deep)

- priority of the right way (shark(kidding^^)>fishing boat>swimmer>rowing boat>yacht under sail>yacht under power>ship)

- sector light (red-unsafe and not good condition below the water/white-safe and good)

- leading light (red/white/green – keep your way in the white light section leading towards onshore)

- if you are in distress and radio a message, 1^st let them know where you are then say something else

- H(high atmospheric pressure) = fine weather/ L(low atmospheric pressure) = rough weather

- H make the sea flat because the air push it, L make the sea free so that makes wave

- the gravity makes wave (I will look into this…from what I learned at university)

- swell

- crossing bars (? - http://www.clubmarine.com.au/internet/clubmarine.nsf/docs/mg17-6+technical)

- it is good to make a slight angle towards the wave because the vessel can jump over waves easily and is better to be ready to run

- wharf ( quay, pier )

- ground tackle (mooring stuffs)

- preferred channel

- point of interest

- cardinal mark – safe

- isolated danger mark – danger

- submerged cable (don’t anchor on it)

- cocked hat, plot course

26092011(day skipper - day 1)

We had the day skipper today. Brett was our day tutor and his pronounce is different from Chris’s. Getting used to Chris’s voice, I felt slightly harder to understand than Chris’s class. We got a book ‘Day Skipper Theory’ published by coastguard and have to get it back to school.

- The sidelights on the port side are red, whereas they are green on the starboard side.(an unbroken light from right ahead to 22.5 degree abaft the beam on its respective side.)

- Most of cases, boats have the right way to starboard.

- Usually, the boat having the wind on starboard has the right way (stand-on), except they are heading same direction.

- bearing through an object (relative velocity - use something fixed on board (ex. Stanchion))

- speed (under 5 knots 200m from shore)

- safety distance 50m (at least)

- an overtaking vessel

- a crossing vessel

- blue peter(a flag for indicating there are divers below it) - within 200m from it, speed down under 5 knots

- the right hand rule(?)

- rescue chopper

- leaving ramp(?)

- The tropic of Cancer

- The tropic of Capricorn

- oscillate

- latitudes (every one of them has different length)

- longitudes (every one of them has the same length – 10800 nmile) we can use this(y-axis) on the chart when we measure the distance between two spot

- New Zealand is in far east ocean because the sun rises earliest ( east 177 something)

- Mercator’s chart (extend the actual size of a slice on the sphere into a rectangular piece)

- horizon – about 7.5 nmile

- VHF (Very High Frequency) international channel - #16

- magnetic polar (slightly different from the due polar and changes every year with 6~8 year period, so map changes every year. If vessels don’t go far away from shore, ignore)

- geomagnetic coordinate system

- magnetic field variation

- deviation

- magnetic compass has to be isolated from electric or magnetic facilities (otherwise it malfunctions)

- engulf

- magnetic variation 19 degree E (variation east compass least – minus 19 from what compass says

- outhaul

- fire

- communication & navigation

- safety

- weather

- barnacle (sea acorn) – prevent them by using toxic paint on hull(still legal)

- anchoring is the best way to avoid further disaster when vessels are on an emergency situation and helps the vessels turn into wave

- turn into wave (more stable) – head sea > beam sea > quarter sea

- when a vessel jump over the crest and rush to the wave hallow, it is likely to be yawning which is very dangerous (lost manoeuvrablity), broaching

- a rope on the stern

- when outboard immersed one time, it would lost power

- when anchoring the vessel, it is not good of the sides towards shore

- 2 minutes form ( where you intend to go? where you launch from? People on boat? When plan to be back? Give to trusted person – contact info of boat party, registration number, contact details for local authorities, boat colour, boat name, size, etc.)

- distress signal (flare ex> red flare parachute)

- sailing on a port tack – give way

- sailing on a starboard tack – has the right of way

- windward boat – give way

- leeward boat – has the right of way

- www.sailingusa.info/

- www.sailingcourse.com

- neap tides VS spring tides

- datum plane

- chart datum – lowest part when low tides

- charted depth – always immersed

- drying height – (?)

- no wet

- wind (from), tidal stream (to)

- ship speed and tidal stream speed are given draw vector lines and assume the distance and the time

- lulls, gusts

- lake – sometimes the weather changes in an hour

- 3 by 5, 5 by 5 ( the clarity of the sensibility of VHF or something)

- channel #16 (call up channel, emergency channel)

- the actual condition is prevailing (?)

- www.metvuw.com

- not a problem

It was really hard class for me to follow, because the things that we learned today were mostly in high school (or college) and they are quite hard to be understood with the second language. There were heaps stuffs(mostly details) but I didn’t get much of them. Bugger…With hindsight, I should have had sailing before.

We have finished AutoCAD session today, have to mark up the drawings we did though. It was good time to learn and remind doing AutoCAD this week. Every AutoCAD user has different tastes, so the more I look how the tutor draws, the more I learn. Even though having pre-experience of AutoCAD, I had almost same problems with other mates. What I felt through last week and this week is my English skill is too weak even I was confident to my listening when I wasn't really into this environment here. What should I do...What I really want to learn is the tiny points which are not common knowledge that Chris or other tutors are saying, but I can't hear that. Writing and speaking? I don't know what to say.

Isometric view and oblique view are different. I think oblique view has one surface that is on the same surface where it is drawn and two other surfaces are looked oblique as compared to Isometric view. We can draw Isometrice view by changing into Iso snap from rectangular snap.

This is a drawing of a flange using array and divide commands.

Temporary frame - drawing chine and gunwale deduction

doubler, through hole inside - I have to understand the concept of this and should have measured all measurements by scale rule. It would be easy to know how they are working.

We handed our small assessments but I have to mark them up by next monday. Heaps of mistakes on them! I will look into the book 'small craft and safety' because we are having day skipper next week.

19092011(Autocad-stem detail, transom development)

We did Autocad today as we did last week. Drawing stem detail including stem bevel and transom development, we had a time learning view port function and view point function with Brett. That was good to know that it is useful and necessary for organising each piece of drawing on the layers into one or more drawing sheets. The class today was mainly the time for self-studying for us. Here are new terms~

flat out(it's an idiom from I listened to Brett)
default
TTR(tangential tangential radius)-one method of making a circle
one to one(1:1)
li(for a command 'list')
layer lock&off are different(be aware of using these properly)

18092011(Auckland International boat show)

Yesterday, my wife and I went to the boat show. There were heaps of boats as usual in Auckland and were massive superyachts as well. This was a bit similar of ones held in Korea, but overall this one here is miles more huge(in terms of everything) than that of Korea. We paid $20 per each for a day pass. Prior to going there, we prepared our lunch naming Ghim-bob(sea weed roll). Yummy~This is it, see below.

Three big boats attracted spectator's attention at first near the entry. One of them is COMO made by Alloy yachts. Two other ones were Thalia, Drumbeg made by Vitters shipyards in Holland. These are them.

 I couldn't take the picture of their bow because they all looking towards the ocean. They looked nice though. Just before crossing the bascule bridge, we saw another one made by Alloy yachts, which name was Jenice of Wyoming.

I always feel good when seeing a mast up in the air. Finding two huge masts are standing far beyond the park near at the end of the harbour that I reckon, we walked to there through the bridge. We saw really big boats there. One was Elandess made by Heesen yachts in Holland and another one was Vertigo which is the last sail boat from Alloy yacht so far, but we didn't see the whole body of it because the other yacht was infront of it.

 Elandess

the transom of Vertigo

masts of Vertigo

The last one was Athena that screened Vertigo, which is made by Royal Huisman in Holland. She has been undergoing a refit at Orams Marine Service so the three masts of her were taked off somewhere near there(I saw a picture on the website.). She was really gorgeous even she got rid of them. Believe or not, she will go to Antarctica for travelling and now is on a painting. I wish I could make the one like that before I die.

 figurehead

 no masts! she used to have three!

There was one more yacht(cruise?) on the other side of the quay. She was Kestrel which had sailed over 1 centry. She was built in 1905!

 Two booths were in the boat show, which have many small booths of ship equipment company, material company, small shipyards and so on.

CCTV?

 heaps of yachts~

Isolated system: no energy, material, information trading with the outside

Closed system: only energy trading

Opened system: those three things trading

ship(construction)

Yacht and ship has completely different construction process and methods mainly because of the size they have and the materials of them being used (wood, etc.). They presumably both start from conceptual design even this step is slightly different from each other.

Conceptual design

Set up a goal and plans of shipyards by demand prediction

Procure design ability for winning a contract (obtain order)

Ship performance evaluation, construction planning, ship cost agreement

Set up ship specification and concept for contract

Order material and make construction white paper

Design

Detail design: draw various outfit drawing order steel material for construction

Construction design: draw shop drawing (concept such as out sourcing for construction efficiency

Construction

Preprocessing/manufacturing: manufacture materials into small for blocks (only for shipbuilding), automatic process maximization by marking, bending, cutting

Assembly: assemble blocks, units, apply specialized process each line

Erection: move blocks, block by block erection, increase dock turnover rate by pre-erection process maximization

Pre-outfitting/painting: docks (mainly for shipbuilding) and quay turnover rate maximization by pre-outfitting/painting

Sea trial/delivery

Check weather various parts of ship are right or wrong

Non-official sea trial (self-inspection by shipbuilder), official trial (under classification, owner, correspondence observing)

Preprocessing sequence

Steel material treatment: store and pile up steel material from steel mills

Surface handling: treatment iron oxide or moisture, oil made during material treatment for later process (shot blasting, sand blasting, etc.)

Main function of construction management system

Demand prediction – analyze and decide data and reference, establish a long-term policy

Long/mid-term planning – basic schedule of shipyards

Production schedule planning – detail schedule for each ship

QM – production and guarantee

Stock control –

  Ship material – order available after contracts (let them stock at proper point so storage period minimization

 Common material – stock available

Facility maintenance – set up maintenance interval for each facility considering property

Cost and human resource

Ship(general,calculation)

I had a time that I read and write some knowledge at university. It is done in MS word but few symbols and formulas are not seen on here. If someone ask me, I would like to upload on google docs and here is the snapshot by PDF. This information is not really related to my course in any ways. I am studying myself to remind things that I have learned and I just want to share.

the book that I'm reading at the moment(know your boat)

from Unitec main library
good for beginners(I am a beginner)

ship(introduction)

This was by far the most favorite subject that I have done, I have not got A+ grade though.

1) ships

What is the ship?
- it can be defined for those vessels which content floatablility, loadability and mobility.

grouping by holding up method
- displacement type: usual ships
- planing type: SES(surface effects ship), hovercrafts, hydrofoil ships, WIG(wing in ground effects ship), etc

grouping by propulsion type
- propeller propulsion ships: controllable pitch propeller, contra-rotating propeller
- jet propulsion ships: waterjet, ramjet
- super conductivity ship

grouping by transporting object
- tanker
- bulk carrier
- container ship
- Ro-Ro

grouping by size
<bulk carrier>
- handy size: 18,000 ton ~ 40,000 ton
- panamax: 60,000 DWT ~ 70,000 DWT (under 32.24m of width)
- cape size: 145,000 DWT ~ 160,000 DWT
-VLBC: 180,000 DWT ~ 200,000 DWT

<tanker>
- AFRAMAX(Average Freight Rate Assessment MAXimum): 80,000 DWT ~ 110,000 DWT
- SUEZMAX(capable of passing through the SUEZ canal): 135,000 DWT ~ 150,000 DWT
- VLCC: 240,000 ~ 280,000 DWT
- ULCC: over 300,000 DWT

Buoyancy
Pressure
Lift - the higer density -> the stronger force

to make a boat into catamaran
benefit: can reduce the wave making resistance because of the hull shape becoming thin
           good stability, can procure wider deck area
drawback: might increase the frictional resistance due to the increasing of the wetted surface area

40 knot * 0.5144m/s * 3600s/1000m * 1km/1hour = 73km/h
1 nautical mile(knot) = 1.85184 km

DW=W-WL

ship statics
GM=KB+BM-KG

ship resistance
free surface: a surface between two objects which have different density

total resistance = viscosity resistance + wave making resistance + residual resistance

 - viscosity resistance = surface frictional resistance + form resistance(pressure resistance) + eddy making resistance

 - eddy(eddy, spray, seperation)

 - residual resistance = wave making resistance + eddy making resistance + air resistance + etc

 - form resistance is related to the ship hull shape(steamline shape)
   surface frictional resistance is related to the wetted surface area and the viscosity
   the biggest factor is wave making resistance because it is proportional to the four times squared speed

ideal fluid
 - inviscid
 - incompressible
 - homogeneous

cavitation

ship basic design
ship: floatablility, loadabliity, mobility
design - an operation of actualizing particular plan
           - a process of continuous decision making
ship design: an operation of actualizing a ship into a product

parametric study
- to calculate design factor systematically, compare the results and find the best one

parametric design
- the fact that when design factor changes, dependent variable changes automatically

a competitive ship yard
- cheaper, reliable delivery, good quality, to build a proven design, after service

ship construction process
1) contract signing
- contain ship hull shape, delivery, cost

2) design

3) stell plate storage
- storage and grouping

4) cutting steel
- produce block

5) assembling block

6) installing engine

3) main dimension

4) main engine horse power

5) light weight
 - the only unknown factor at the begining of the design
 - empty ship/spare parts and inventory/oil and water(minimum quantity necessary for main engine starting)
 - deadweight = displacement - lightweight
 - displacement will not really be changed into a big difference from the initial design figure
 - because displacement is seriously related to speed
    a. LWT = SWT + OWT + etc
    b. analysing performanced data
    c. structural quantity estimation by alteration of main dimensions
    d. structural quantity estimation by section examination
        - aft part

26) damage stability calculation

27) damage stability examination & review above dimensions

28) if needed, it is availlable and obligatory to review any level at any process with an evaluation of design objective


to extend length
 - cause high tax pay
 - increase material, decrease DW
 - worst choice

to extend dreadth
 - difficult

to extend depth
 - nice and easy

basic rules and regulations
1) international convention on load lines
 - decision of summer load water line(scantling draught)

 - estimate

There are so many things to rearrange that I learned. Hit the ground running!

15092011(brainstorming-Autocad continued)

We drew deckcamber of our 2.5 dinghy on station 3 and a temporary frame for that. Though, 2D or 3D CAD or whatever are important and it is good to do reasonably well, what I liked to do was brainstorming. There are heaps of people who are bloody good at 2D or 3D design, but my brain cannot be possed to the other people but we can share it by brainstorming with other designers, which is cool. We had 2 times of brainstorming, one of which was for how to find the height of deckcamber mentioned above, another one was for what kind of things including resource, sustainablity, mamagement and many things like those for making SUPB(Standing Up Paddle Board) that Andrew would like to build. I think that was really important time to think about process and sequence which are same as ones in real world. I like brainstrorming~ There is no resistance, no hesitating, no inspection, no debating, but just popping out.

13092011(AutoCAD-in the lab)

We started doing AutoCAD. There were some new terms and some stuffs that will be needed to make a portfolio. Actually, I drew a AutoCAD drawing of a small house at university in 2008 but there wasn't much curved lines on it and the thing is I can't remember most things that I learned(poor little memory..). There was no AutoCAD class in my major, but I wanted to have that so I did one in architecture department. The class today reminded me quite a bit commands, which is happy. We drew our tool box, oil stone box, long board and water scupper. AutoCAD is a really powerful tool for architects but it is still good for naval architects and they are using a lot as well.

New terms
third angle orthographic drawing
plan: same as halfbreadth for third angle orthographic drawing
elevation: profile
end elevation: bodyplan
perspective drawing(see through)
isometric drawing(see surface)
bird's eye view
quadrant
water scuppers

what will be good in a portfolio
words - the vast majority of what I am doing
pictures - a bit
videos - not at all
sketches - let's do this, I like hand writing or drawing
examples - a bit
concepts - think about this
process - good
reflection - good


commands
@: means from
<: anti-clockwise direction angle from x-axis on the right side quadrant
line
