$7.9 billion yacht would be the largest floating structure

What hosts 60,000 guests, costs $7.9 billion dollars and is shaped like a turtle? It’s Pangeos, a terayacht that could become the largest floating structure the world has ever seen.

Securing (or mooring) a floating structure such as offshore oil platforms to aquaculture farms to the ocean floor most commonly involves tethering the structure to the seabed using anchors and lines.

Here's a breakdown of the process:

Anchors

Types: Different types of anchors are used depending on the size, weight, and location of the structure. Some common options include:

Gravity anchors: These are heavy blocks of concrete or steel that rely on their weight to resist movement.

Drag anchors: These anchors have flukes that dig into the seabed when tension is applied, providing additional holding power.

­Suction anchors: These anchors use a vacuum created by pumping water out of a chamber to embed themselves in the seabed.

Pile anchors: These are long, slender tubes driven deep into the seabed, offering significant holding capacity.

Lines:

­Materials: Typically made of strong, durable materials like steel chains or wire ropes, nylon, or polyester ropes, chosen based on their strength, elasticity, and resistance to corrosion.

Configurations: Lines can be arranged in various configurations, such as single-point mooring (SPM) with a single anchor or multi-leg mooring systems with multiple anchors for increased stability.

Deployment:

Positioning: Anchors are strategically placed around the structure, considering factors like water depth, currents, and prevailing wind directions.

Connection: Lines are securely attached to the structure and the anchors, ensuring proper tension and load distribution.

Additional factors:

Environmental conditions: The design and selection of mooring components consider factors like water depth, currents, wave action, and potential seabed conditions.

Maintenance: Regular inspection and maintenance of the mooring system are crucial to ensure its integrity and prevent failures.

Alternatives to mooring:

Pile driving: For certain applications in relatively shallow waters, piles may be driven directly into the seabed to provide structural support without requiring tethers.

LONDON | Roll out the barrels: Christo artwork floats on London lake

LONDON (AP) — The ducks, geese and hardy cold-water swimmers in London’s Hyde Park have a new neighbor: a monumental floating structure made from 7,506 stacked barrels colored bright red, mauve and blue.

“The London Mastaba” is the latest work by artist Christo, who has previously wrapped Berlin’s Reichstag in silver fabric and festooned New York’s Central Park with thousands of saffron-colored cloth “gates.”

His first major work in London rises 65 feet (20 meters) above the park’s Serpentine lake, in a sloping-sided rectangular shape adapted from ancient Egyptian tombs. The colors have been chosen to complement the lush greenery and gray-blue skies of a London summer.

The sculpture, on display from Monday until Sept. 23, is one in a series of barrel-based artworks Christo has created since the 1950s.

An ambitious new project is hoping to help clean the world’s oceans with a trash collector that is reportedly the longest floating structure in recorded world history.

Back in 2013 TrueActivist reported that a 19-year-old developed a plan to clean up the world’s oceans in just 5 years, removing 7,250,000 tons of plastic. However, last week, Boyan Slat (now 21), founder and CEO of The Ocean…
