The first spar platform designed for production was the Neptune spar, located in the Gulf of Mexico, and was installed in September 1996 by Kerr McGee. [ 5 ] The first, and thus far unique, cell-spar platform was Kerr-McGee's Red Hawk spar (7 ea. 8 m (26 ft) diameter cells). [ 6 ]
The weight is released by sending a coded acoustic command signal and stays on the ground. Deep water anchors are typically made from steel and may be as large as 100 kg. A common deep water anchor consists of a stack of 2–4 railroad wheels. In shallow waters anchors may consist of a concrete block or small portable anchor.
Lockheed Martin claims that the DCS has an endurance greater than 24 hours, triple that of the current SEAL Delivery Vehicle and twice that of the Shallow Water Combat Submersible the DCS will serve alongside. [5] Unlike its predecessor, the Dry Combat Submersible will be deployed from surface ships rather than from larger submarines. [1]
Single anchor leg mooring (SALM), which can be used in both shallow and deep water. [1] see Thistle SALM as an example. Vertical anchor leg mooring, which is seldom used. [1] Two types of single point mooring tower: Jacket type, which has a jacket piled to the seabed with a turntable on top which carries the mooring gear and pipework [1]
Water is then pumped from the interior of the caisson to create a vacuum that pushes the plate anchor underneath to the desired depth (Step 1). The plate anchor mooring line is then disengaged from the caisson, which is retrieved by water being forced into the caisson, causing it to move upwards whilst leaving the plate anchor embedded (Step 2).

A suction caisson can effectively be described as an inverted bucket that is embedded in the marine sediment.Attachment to the sea bed is achieved either through pushing or by creating a negative pressure inside the caisson skirt by pumping water out of the caisson; both of these techniques have the effect of securing the caisson into the sea bed.
After Mesquite was off the bottom, the wreck and barge were winched out of the shallow water. Once clear of the shoal, they were towed to the sinking site about 1.5 miles (2.4 km) away in Keystone Bay. The wreck was lowered to the bottom in 117 feet (36 m) of water. The total cost of the removal process was approximately $2 million. [44]
