The initiation wire is more flexible and more easily handle-able than your product. As it's specifically designed for connecting between masterlinks, hooks, other wires it can easily be fitted to the DMA.
It's also cheaper and far more easily replaceable than your product. So you want the end...
And DNV-RP-C205 states
"Three hours has been introduced as a standard time between registrations of sea states when measuring waves, but the period of stationary can range from 30 minutes to 10 hours."
DNV-RP-H103 mentions 3 hours as well.
Remember the 1.86 factor which is said to be the...
Looking at my Barltrop and Adams page 256. It states:-
"Over an interval of 3 hours the statistics do not change very much and the seastate may be described by significant wave height (Hs) and mean zero crossing period (Tz)."
I've been asked about a 2km long umbilical and what "overage" and the size of expansion loops at one end are required.
I heard that ordering 1% over the point to point length is appropriate and it's dependent on seabed topography.
What codes have anything on this? Is 1% too much?
Thanks
Thank you Patricia for your help. I was employed as a lowly structural engineer for the THORP project and have worked on Dungeness A & B. Due to the UK's decision to go ahead with NP I am mindful of the clear up problems we have for the previous generation of reactors.
So my question really is...
Does anyone know which plant type produces waste materials with the shortest half life?
I've heard that some produce waste with a half-life of hundreds of thousands of years which is OTT IMHO.
Yes - I can see an analogy of a column subjected to buckling loads. Axial load producing more lateral deflection which produces more LD and so on.
Those stiffener joints. Can you recommend a code for these stiffeners?
My Trevor Jee notes avoid the "z" vs "s" problem by talking about "ovality".
The notes talk about "a runaway flattening of the pipe". Ulp!
Trevor Jee's ovality is the same as narendranath's but they state that BS8010 has a different inherent factor of safety and that the ovality in BS8010 is...
From what I understand it's filled with water (pressure neutral) and has water moving up and down in it. There might be a mini water hammer effect in it though.
Interestingly enough BS 8010 Part 3 1993 has a different formula. Looking at section C.1.2 External pressure
it states
fo = [Dmax - Dmin] / [Dmax + Dmin]
Where fo is the initial ovalization of the pipe cross section (not to be taken as less than 0.025.
The same as the above is for flexible...
James Lovelock has proposed the construction of massive ocean pipes "100 to 200 metres long, 10 metres in diameter and with a one-way flap valve at the lower end for pumping by wave movement" to pump water up from below the thermocline to "fertilize algae in the surface waters and encourage them...
It's not just the basic cost but installing the thing. Perhaps contact the companies "Oceaneering Multiflex" for the basic cost of the cable and "Subsea7" for an idea how much it would cost to lay.

There's plenty of programs for designing platforms (STAAD, Abaqus etc. As for the second part a company by the name of Zentech Limited (UK) produced something called Holismat (Holistic materials processing). Also they did a fancy all-in package for Statoil (included maintenance schedules). But a...
