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.
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.

CBM – conventional buoy mooring; CBM – coal-bed methane; CCHT – core chart log; CCL – casing collar locator (in perforation or completion operations, the tool provides depths by correlation of the casing string's magnetic anomaly with known casing features) CCLBD – construction / commissioning logic block diagram
Decanting from several storage cylinders in succession, generally using a procedure to maximise charge pressures. Often used in partial pressure gas blending. catenary anchor leg mooring. Also: CALM. Single point mooring type named for the catenary curve of the anchor cables that hold the buoy in position. Also referred to as single buoy ...
The anchor begins to sink and the mooring cable unwinds until the plummet reaches the sea floor (5). Triggered by the decreasing tension on the deep line, the mooring cable is clamped. The anchor continues sinking down to the bottom of the sea, pulling the mine below the water surface to a depth equal to the length of the deep line (6).
On August 8, 2000, at 8:37 a.m., the sub broke the surface for the first time in 136 years. Image of early Constellation Space Suit prototype – February 2010 On August 2, 2006, NASA announced it would issue a Request for Proposal (RFP) for the design, development, certification, production and sustaining engineering of the Constellation Space ...
Texas A&M Engineering Extension Service operates as part of The Texas A&M University System and is overseen by the university's board of regents. [6] The agency is composed of six divisions: Emergency Services Training Institute (ESTI), Infrastructure Training & Safety Institute (ITSI), National Emergency Response & Rescue Training Center (NERRTC), OSHA Training Institute Southwest Education ...
anchor buoy A small buoy secured to a line attached to the crown of an anchor. The line allows the anchor to be unhooked from an obstruction, such as a rock or another vessel's anchor cable, so preventing raising the anchor in the normal way. [13] anchor chain . Also anchor cable. A chain connecting a ship to an anchor. anchor detail
