Under the influence of water currents (and wind if the top buoy is above the sea surface) the shape of the mooring line can be determined and by this the actual depth of the instruments. [ 8 ] [ 9 ] If the currents are strong (above 0.1 m/s ) and the mooring lines are long (more than 1 km ), the instrument position may vary up to 50 m .
Mooring involves (a) beaching the boat, (b) drawing in the mooring point on the line (where the marker buoy is located), (c) attaching to the mooring line to the boat, and (d) then pulling the boat out and away from the beach so that it can be accessed at all tides.
Line stopping or line plugging is a means of isolating a piping system to provide a shut off where none exists. This process serves as a control, or temporary valve , that can be removed after permanent alterations or valve replacements/additions have been made.
Single point mooring at Whiddy Island, Ireland Single-point mooring facility off Puthuvype, Kochi, India. A Single buoy mooring (SrM) (also known as single-point mooring or SPM) is a loading buoy anchored offshore, that serves as a mooring point and interconnect for tankers loading or offloading gas or liquid products.
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 stationary at a fixed location. In contrast to that, the Lagrangian way measures the motion of an oceanographic drifter, the Lagrangian drifter.
The monkey fist and other heaving-line knots were sometimes weighted with lead (easily available in the form of foil used e.g. to seal tea chests from dampness) although Clifford W. Ashley notes that there was a "definite sporting limit" to the weight thus added. moor 1. To attach a boat to a mooring buoy or post. 2. To dock a ship. 3.
The anchor line, rope, or cable connecting the anchor chain to the vessel. anchor sentinel. Also kellet. A separate weight on a separate line that is loosely attached to the anchor rode so that it can slide down it easily. It is made fast at a distance slightly longer than the draft of the boat.
A Schlenk line with four ports. The cold trap is on the right. Close-up view, showing the double-oblique stopcock, which allows vacuum (rear line) or inert gas (front line) to be selected. The Schlenk line (also vacuum gas manifold) is a commonly used chemistry apparatus developed by Wilhelm Schlenk. [1] It consists of a dual manifold with ...
