seakeeping criteria

[sirhamid]

hi dears

I try to fine a refrence about human acceptable seakeeping criteria and some tabular data about roll,pitch and heave acceleration on crew performances limited.
:confused:

[yipster]

it IS somewhere ( but where? ) on these forums at what states how sick we can get :P

Are you asking about passengers or working seamen?

about working crew or seaman, I asked.

[sirhamid]

ok guys
tell me please what mean the "10% loss after 2 hour" on MSI (mosion seakness index curve) ?!!!!:confused:

[TeddyDiver]

It means 1of10 being too sick to do anything except g e o r g e.. avarage..

you should read:

"Effects of Motion at Sea on Crew Performance: A Survey" by Stevens and Parsons, in SNAME's Marine Technology, vol 39. Jan 2002.

One of the best papers on the subject i've ever read.

[sirhamid]

amaaaaaz AdHoc.

butttttttt! i read that,so it sued about people not on my culture!!
i mean the peaple on diff. country respond diffrent to sea wave.is'nt it?

also i like very mush the Ad-Hoc analysing ,do U know?

[Ad Hoc]

The physiology is the same know matter where one is from i.e. everyone has a vestibular system!

Some difference is how people believe they respond, and some might get sick even when they think about it.. but eventually after getting used to water and "normal" motion it's like AdHoc said..

[sirhamid]

oh No,ADhoc.

its verydepend on ergonomy and human response.maybe on belives this diffrence was created but on the crews,the nation is very effective.

[apex1]

You do´nt find any difference in the way people of different ethnic roots respond to ships motion. Thats a fairy tale.

[sirhamid]

yes but maybe.

[apex1]

yes but maybe.

No. not maybe.
Ask any of the bigger shipping companies employment office if they have noticed such a difference.
You know, such easy is colour TV!

[sirhamid]

dear apex1.
offcourse U know the statistics and thats concept.
all of the MSi curves and its backbone is on statistic data.
and the statistic data depends on the environment data ,so this environment(example mans) are diffrent on the experimental domain.
can I descript my mind?

[apex1]

Sorry I do not understand your last statement?

[Ad Hoc]

man = physiology=eye=ears=brain=everything else, ie, we are all made the same

[apex1]

man = physiology=eye=ears=brain=everything else, ie, we are all made the same

I hope not!:D
