The prototype Battenberg course indicator of 1892. The guide bar and circular disc are at the bottom of the picture; the position bars are at the top and left; the speed bar stretches up and right to meet the almost horizontal diameter grove at the 3 o'clock position
Mooring as deployed in Fram Strait with top buoy, a CTD-sensor, two rotor current meters, acoustic release and train wheels as anchor. A mooring in oceanography is a collection of devices connected to a wire and anchored on the sea floor. It is the Eulerian way of measuring ocean currents, since a mooring is
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.
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]
Mooring ring (permanent) affixed between the edge of the canal and the tow path, with (boat operator supplied) rope to the boat. [ 17 ] Mooring bollard (permanent) affixed canal-side on lock-approaches for the short-term mooring of advancing boats and lock-side to assist in ascent and descent.
Suitable for nuclear-powered warships, and part of an operational Naval base or a building and refitting yard. All X-berths have as an integral part of their safety arrangements a permanent health physics department, a local emergency monitoring organisation and a local safety plan prepared under the auspices of a local liaison committee.

Spars are permanently anchored to the seabed by a spread mooring system composed of either a chain-wire-chain or chain-polyester-chain configuration. [2] The cylinder comprises a number of tanks; the lowest contains ballast, mid-water and/or extracted oil, the upper, air for buoyancy. [ 3 ]
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.
