What is the difference between a 'huge' tanker and a 'big' tanker ?Originally posted by stupidissmart:It depends on how big the ship is going to be. If it is huge tanker, of course it can't pass through Pulau Ubin. However wat if the ships r small tugboats ? The strategy is to let big tankers dock at Malaysia port while small tugboats will take their place to transport goods to the nearby region.

If a bridge is made, [b]r u certain that after water is able to pass under the causeway the water level in pulau ubin won't sufficiently rise since the deposits in it get carried away by the water. [/b]
continuing post by stupidissmart:The bad Political SENTIMENTS have certainly been flowing from the north and dumped on us at the Straits of Johor - causing all the shallow feelings that exist on both sides of the Straits.
Note tat for many years, sentiments had been deposited at this narrow straits since it is close at the end.

And wat is to stop Malaysia from slightly cutting their side of the shore make it deeper to allow ships to go through ?
continuing post by stupidissmart:Surely, the ball is in their court, and as PM GCT had said they will have to give us a good reason why the existing Causeway need to be demolished, and replaced with a new bridge that will cost us at least $500million.
Now the ball is in their court and they have a chance to do it, even though the scale of work involved may be big. Remember good and crazy minister comes and goes, but things concerning about the causeway is almost forever. I do not want to take chances.
I will give you an OSCAR equivalent for great scientific thinking.I believe u probably fail to understand tat I am NOT talking about your regular BATHTUB. We r talking about the sea currents movement ! If the bridge is clear, sea current will be able to flow freely not just at the southen end of singapore but at the northen end as well. During certain seasons, due to the different temperature of different bodies of water, sea current will moves from the eastern end of singapore to the western end or vice versa. Since the velocity of these water is fast, they will tend to cary away sendiments with them. As such, the depth of the water around the region will goes deeper. If these water is through, it will be able to clear away the sentiments brought over by the malaysia river as well.
For Achimedean Principle to work, the amount of water rise or displaced, will depend on the amount of mass being added - NOT removed.
A rise in sea water level around Pulau Ubin, caused by water being released with the existing Causeway being demolished ?
The deposits have been - since time immemorial - flowing down the rivers from Peninsula Malaya into the Straits, with or without the bridge, the deposits have been carried and flowing in and around the vicinity of Ubin and Tekong.
Is the water distance between singapore and malaysia really tat shallow ? I doubt it as 60m in distance will be sufficient for small vessel to pass through like in Suez Canal. Will the work involved be tat incredibly great ? We r working on existing sea bodies (not dry land) with the new improved technology today, for a short distance. Do u think malaysia cannot afford to do such work ?
Nothing except the budget - and its their ringgit anyway.
Nothing can stop Malaysia to do anything to do whatever they must do; but certainly the cutting on their side will be anything except 'SLIGHTLY'.
It will have to be a major effort in not only cutting the sides of the shore lines, but also DREDGING THE SEA BED for the ENTIRE DISTANCE of the Johor Straits - beginning from the mouth of the Straits.
If the Southern Ports located in Johor State are to be successful - especially that at Pasir Gudang - they will need to have enough manouvering space along the Johor Straits.
Johor State will have to see a major land slip into the waters of the Straits - up to 1 km wide, along its entire southern coastline facing Singapore, which will result in the loss of Johor Bahru, including the majestic Sultan's Palace, the Straits View Hotel, and quite a large cut of commercial, industrial and residential properties.
The bridge can be built, but it cannot allow water to flow through. If they just wanted the causeway to modernise, it can still be done, and more cheaper and safer if the old foundation is left alone. We can still negotiate with the malaysian since their main objective is just to modernise the causeway. Wat pros do we have for making the water being able to pass through ? It may turn life threathening if we r too complacent.
Surely, the ball is in their court, and as PM GCT had said they will have to give us a good reason why the existing Causeway need to be demolished, and replaced with a new bridge that will cost us at least $500million.
Perhaps for the sake of long term goodwill between the two countries, Singapore will probably accept the New Bridge being constructed. This will result it being the key to open the deadlock on the Water Issues, Railway Land, CIQ, CPF belonging to Malaysian workers, and any other side issues that have been political baggage hanging over our relations for the last 30 years.
Will the New Bridge present any 'LIFE THREATENING' issues to Singapore's well being ?
The New Bridge can hardly allow ocean going vessels to sail in both directions of the Straits, as the piers supporting the bridge at the Second Link are too narrow - and the underside of the bridge is too low - to allow even coastal ships at 6000 dwt to sail through the piers.
Water levels rise by the tides, by gravitational pulls of the moon and the sun, and by the melting of the polar caps that ADD NEW VOLUME OF WATER into the OCEAN.Originally posted by stupidissmart:
Maybe the tugboat is a wrong term to use. However from a website from Maesk, the width of a boat can go to as low as 25m. HOw wide is the causeway ? It is 1056 m, which can be considered as the shortest distance between singapore and malaysia. HOw many 25 metres ship can filled 1 km ? 40 ships sailing side by side. How wide do u think suez canal is ? The minimum width is 60m, Wat is the problem then ? About your traffic issue, they can follow Suez Canal and state that the ship should move in one direction only. It is achievable

And wat has your sembawang shipyard got to do with anything ? All it ever says is tat OCEAN going vessel can go through half of the route along singapore, and a small one can easily navigates for the remaining journey. In the past singapore is able to dredge to make the water deeper. Do u think malaysia can't do the same for area near pulau ubin ?

I am not sure if there is any point to debate with you, considering the line of thought that you prefer to take. It will be embarrassing for me to sink the positions that you put yourself in.Firstly, Sembawang Shipyard was mentioned as a reference to indicate that ships (not only huge or big ships) up to 400,000dwt can sail up the Straits of Johor - from the eastern side, which is Changi-Ubin-Tekong channel.
You had made a moot statement previously, concerning the need to use 'tug' boats to transfer cargo and sail up the Straits towards Pasir Gudang Port.
Secondly, if you only look at the widest part of the Straits of Johor as 1056 meters, are you not a little 'shortsighted' in your thinking by not looking at also the NARROWEST part of the Straits ?
Considering that the Malaysian half of the Straits of Johor is too shallow for ocean going ships to sail - due to the SEDIMENTS flowing down the main rivers from Peninsular Malaysia - the 1056m width is practically useless to even be considered.

Thirdly, based on the above second point, is there any possibility of lining up 44 ships side by side, and sail up the Straits of Johor.
Hmmm, I wonder who can be so foolish to even think of this approach ?
The PORT must be built to receive the SIZE of SHIPS that Shipping Lines build for the most economical and profitable returns.
No one build planes to fit airports, but airports are constantly upgraded to receive bigger planes. Surely you have heard your idols mention - Improve and Upgrade or Loose Out ?
Fourthly, there are Port Navigation Rules to be observed, in which safety distances are to be maintained between vessels.
With large ocean going vessels needing large expanse of space to manouvre or come to a stop, safety distances become critical in the Straits of Johor.
Reference: East Johor Straits Pilotage Guidelines
http://www.mpa.gov.sg/homepage/services/pilotguide/definitions_miscellaneous_guidelines.pdf
Fifthly, you seem to have a preference to take the numbers out of context for your planned counter to my post.
You consider the 1056m length of the Causeway, as an indicative of the continuous equi-distant width of the Straits of Johor, without considering the lesser value at the narrowest choke point between Singapore and Johor, or Singapore and Ubin or Tekong.
You prefer to look at only the size of 22meters being the beam or width of a Maersk Line ship (what kind you did not mention).
For the Malaysian Ports of Pasir Gudang or Tanjong Pelapas, or even Singapore's PSA, to be profitable - these ports will need to receive the largest container ships, very large crude carriers (VLCC), or Roll-on Roll-off Car Carriers (Ro-Ro Ships).
Most of these vessels have a beam of 30 to 40 meters, and their lenght will be over 200 to 300 meters (or about 2 to 3 football field).
Safety distance will have to be keenly observed, and if you care to look up the Port Navigation Rules, the viability of Malaysian Government Plan will be questioned.

Will you look at the map of Singapore again - and note the length of the entire Straits of Johor ?
http://www.divetravel.info/destinations/southeastasia/singapore_zoom.htm
From the following site of Johor Port of Pasir Gudang, you can observe the depth posted as between only 5 to 13 meters:
http://www.portsworld.com/ports/johorport.htm
From the sites of the various shipping lines given in the preceding posting, you will note that the depth (or height from hull bottom to main deck surface) of most high capacity container ships is more then 19 meters, with a sea draft of 11 meters (from water line to hull bottom).
The depth of the entire length of the Straits of Johor will have to be able to cope with this kind of traffic.
You question - 'Can Malaysia afford it ?' - which should be replied by Malaysians, one of whom seems to express the general feelings that this bridge is a waste of their resource, when there are more urgent issues that need government attention.

Originally posted by stupidissmart:The Malaysian Ports of Tanjong Pelapas do not have problems docking ocean going ships.
WHy do u think they will have a problem docking at one end of malaysia, then change to a smaller boat and send the goods directly to the region ?
continuing post by stupidissmart:It has to do with PROFITABILITY and ECONOMIC VIABILITY for the Shipping Lines to use ever larger ships to 'move more at one go'.
They could easily use the smaller ship and sails direct to Indonesia, Vietnam etc isn't it ? Wat is more, these smaller vessel can still fare well in seas.Wat is the problem of them travelling directly to Australia or China if the goods tat need to be transported isn't of a great volume ?
