Moorings fix the buoy to the sea bed. Buoy design must account for the behaviour of the buoy given applicable wind, wave and current conditions and tanker tonnages. This determines the optimum mooring arrangement and size of the various mooring leg components. Anchoring points are greatly dependent on local soil condition. [2]
The properties of chain, versus wire, mooring lines have been investigated, with chain mooring lines causing reductions in anchor capacity of up to 70%. [6] Thus, where appropriate and cost-efficient, wire mooring lines should be used. The embedded section of a mooring line contributes to the anchor's holding capacity against horizontal movement.
Units varies in strength, there are 95K, 120K, 150K, 170K, 225K, 340K, 460K, 600K The number indicates their working strength in pulling force, and 150K means the unit is capable of pulling maximal 150000 pounds. This is based on the hydraulic force acting on the size of the unit's piston size.
A Consulier GTP-LX prototype Consulier GTP Series II The Consulier GTP, conceived by Warren Mosler in 1985, was a 2,200 pounds (1,000 kg) mid-engined sports car built in two series. The first series sold about 70 copies and was powered by a Chrysler 2.2 I4 Turbo II engine producing 175 hp (130 kW). [ 3 ]
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.
SBM Offshore N.V. (IHC Caland N.V. prior to July 2005) is a Dutch-based global group of companies selling systems and services to the offshore oil and gas industry.Its constituent companies started their offshore activities in the early 1950s and SBM subsequently became a pioneer in single buoy moorings (SBM) systems.

As a verb bitt means to take another turn increasing the friction to slow or adjust a mooring ship's relative movement. [1] Mooring fixtures of similar purpose: A bollard is a single vertical post useful to receive a spliced loop at the end of a mooring line. [1] A cleat has horizontal horns. [4]
Snubbered first stage fan blades (snubbers, or mid-span shrouds, had been introduced by GE on the YJ93 first stage compressor blades [5]) The high-bypass ratio of 8:1 for the TF-39 had its origins in the lift-fan technology demonstrated by GE in the XV-5 Vertifan aircraft. [4]
