Hi All
Question from a simple mechanical/hydraulic/Subsea engineer...
In a windfarm what are the pros/cons of switching from a 66Kv copper subsea cable to a 132Kv cable?
Does the cable physical CSA / diameter change or is it just an increase in power for the same properties? Obviously, all...

Can someone offer some clarity please on the difference between MoC and RfC.
This is a constriction project with offshore operations, my understating is RfC would be used to make change requests to the Contract or Employers Requirements after contract award but before operations.
An MOC...
How does this sound folks?
Birdcage buckling Is a phenomenon which occurs in an armoured subsea power cable when laid or moved under low tension. The axial torsion within the cable generated by both the twisted cores and the steel wire armour produce a twist, this in turn causes a reduction in...
Esteemed colleagues
I’m about to start a dialogue with the local council as spokesperson for flood action group, a group of residents whom have repeatedly being flooded (one is my mother in law).
I’m a mechanical engineer in oil and gas so have no idea what I’m talking about when it comes to...
Im a simple subsea engineer and have googled the above and got mixed info.
Can anyone please advise the ratio of water, postcrete and gravel (ive loads of gravel) for a simple foundation I’m preparing for a green house. I will dig a foundation pit 8 inches deep for 3 inches of hardcore (using...
folks
I appreciate the difference is minus the displaced volume of seawater but is there a rough ratio I can apply, ie if steel weighs 7850kg/m^3 and water is 1000kg/m^3 can I apply the ration (7850-1000)/7850=0.872 roughly providing no etrapted air?
Tks
Is it necessary to let steel sea fasting brackets (S355) fastening containers to a ship’s deck cool down before MPI?.
Would DNV insist on it, it is a DNV registered vessel?
Thanks
Does anyone whom is familiar the PED know if it is mandatory to test equipment (like hydraulic cylinder) using a chart recorder ie electronic pressure monitoring over time?
Quick one guys ATEX is new on me...
Taken from wikapedia:-
Zone 2 (gases / Vapors)Class I Division 2 (gases)- An area in which an explosive mixture is not likely to occur in normal operation and if it occurs it will exist only for a short time.
Is this considered SAFE ZONE offshore?
I’m looking for some advice on finalising the hydraulic design on a cable tensioning system.
Four Cylinders are being used to pull a 160 strand cable to 1274t tension over approx. 840mm stroke, the cylinders are 300mm bore x 200mm rod x 700mm stroke. Buckling is ok.
From 0mm to 700mm the load...
