Understanding Pool Anchors

Anchors have seen quite an evolution over the years, with the first anchors almost certainly being nothing more than a heavy rock at the end of a chain. Over the years, the fisherman anchor, the fluke, the plough, the Admiralty and grapnel designs all had their day, from the 19th century on. Later in the 20th century, more modern designs such as the Bruce, Bulwagga and spade anchor all came into play. They were designed to set very quickly and generate high holding power, with each having its advantages for different applications and different-sized vessels.

One of the newer designs of the last few decades is the POOL N anchor. Designed with a shorter shank and angled flukes, each of the POOL N anchor’s flukes are two separate steel plates, shaped and welded together. This means that:

Each fluke has a hollow core
Flukes are more resistant to bending forces
The anchor’s overall weight is lower

Another variation is the POOL KM, a naval anchor designed by the Royal Dutch Navy and Technical University of Delft. Devised for monobow use, the POOL KM anchor means that each vessel only needs one anchor, chain and winch. This results in all forces being on centerline when the ship is at anchor, meaning that the ship will be very stable and will present less of a wavebreaker.

The POOL-TW anchor features sharpened inner edges on the flukes, and crownplates to keep the anchor from digging in too deep. Although it is designed to dig in quickly and hold fast, it can also be pulled out with a fairly low amount of transverse force when it’s time to weigh anchor and sail.

All POOL anchor designs are available for smaller vessels such as fishing boats or frigates, and can be custom-made out of non-magnetic materials or polished stainless steel (for flashy-looking yacht applications). POOL anchors, by design, are well-balanced and lower in weight, meaning an overall weight reduction of 25-50% (when considering the overall weight of the chain, windlass and other anchor equipment onboard). Better balance means less chance of damage to the ship or anchor itself; if the anchor does become damaged, it can be repaired again, unlike many other designs. It also means greater safety for the ship itself, with a holding power that is 1.5 to 2 times that of a conventional anchor design.

Best European Country for a Civil Engineer?

I am a Civil Engineering Undergraduate from India. I wish to apply for a Master's in Construction Engineering, Project Management or Structural Engineering and get a few years of rich work experience thereafter.
Which European country can be considered the best considering the quality of education, ease of admission to the University, job opportunities, ease of getting a work permit, standard of living and extent of taxes to be paid.
Some options may be
-Norway and NTNU
-Sweden and KTH Royal Institute of Technology
-Netherlands and TU Delft/TU Eindhoven
-Denmark and TU Denmark
-Switzerland and ETH Zurich
-Germany and TU Munich/TU Berlin/ Any other reputed institute
-Austria and TU Vienna
any other place?
Please help.

Theres alot of work for engineers in sweden currently.

or so the rumor goes:)
