The boat was declared a total loss at an estimated cost of $1.14 million. The Ram XVIII was a 215-foot liftboat, built in 2015 and owned by Aries Marine Corporation in Lafayette, Louisiana . The National Transportation Safety Board (NTSB) determined that the probable cause of the accident was an industry failure of not providing liftboat ...
The ship becomes blocked on the deck of the floating dry dock for repair. Most floating dry docks have no engine and are towed by tugboats to their destinations. Floating dry docks come in different sizes to accommodate varying ship sizes, while large floating dry docks come in sections and can be combined to increase their size and lift power.
In geotechnical engineering, a caisson (/ ˈ k eɪ s ən,-s ɒ n /; borrowed from French caisson ' box ', from Italian cassone ' large box ', an augmentative of cassa) is a watertight retaining structure. [1] It is used, for example, to work on the foundations of a bridge pier, for the construction of a concrete dam, [2] or for the repair of ...
A small motor-boat lifted from the water by a boat lift at La Rochelle, France, 2016. Smaller devices called "Boat lifts" are available that simply raise yachts, sailboats, or small watercraft above the water level at a dock for storage, for reduced maintenance cost and increased security. They can be operated by cables, by hydraulics, or by ...
Another form of electronic dry box technology utilizes multi-porous molecular sieve desiccants to absorb moisture. This moisture and humidity control technology is renewable without having to replace desiccant and is capable of reaching low humidity (20%RH or less) to ultra low humidity (5%RH or less) levels.
A floating dry dock is a type of pontoon for dry docking ships, possessing floodable buoyancy chambers and a U-shaped cross-section. The walls are used to give the dry dock stability when the floor or deck is below the surface of the water. When valves are opened, the chambers fill with water, causing the dry dock to float lower in the water ...
The stuffing box prevents water from entering the boat's hull. In many small fiberglass boats, for example, the stuffing box is mounted inboard near the point the shaft exits the hull . The "box" is a cylindrical assembly, typically of bronze, comprising a sleeve threaded on one end to accept adjusting and locking nuts.
It was first assembled into individual boxes that were joined in multiples to construct docks, causeways, barges, dry docks, floating cranes, marine railways or whatever was needed. Capt. Carl A. Carlson CEC of the War Plans Office came up with the concept of NLPs in 1935, [ 1 ] but it was in 1940 that the US Navy looked at the idea more seriously.
