2. Umbilical cable - Wikipedia

   en.wikipedia.org/wiki/Umbilical_cable

   A typical 4-part diver umbilical will also have a 1 ⁄ 2 inch (13 mm) bore hot water supply hose for the diver's exposure suit. A 5-part diver umbilical will also include a video cable to allow the surface controller to see the video picture transmitted to the surface from the diver's hat camera (video camera mounted on the helmet, facing ...

3. Level luffing crane - Wikipedia

   en.wikipedia.org/wiki/Level_luffing_crane

   The first of these systems used mechanical clutches between luffing and hoist drums, giving simplicity and a "near level" result. [ 5 ] Later systems have used modern electronic controls and quickly reversible motors with good slow-speed control to the hoist winch motors, so as to give a positioning accuracy of inches.

4. Beartrap (hauldown device) - Wikipedia

   en.wikipedia.org/wiki/Beartrap_(hauldown_device)

   Typical use of the beartrap involves a helicopter hovering over the landing pad on the deck and lowering a line with an attached probe on the end. This probe is attached by the deck crew to a heavier cable that passes through the center of the beartrap from a winch below the flight deck. The cable is pulled back up and secured to the helicopter.

5. Active heave compensation - Wikipedia

   en.wikipedia.org/wiki/Active_heave_compensation

   [4] [5] Hydraulic "active boost" winches control the oil flow from the pump(s) to the winch so that the target position is reached. Hydraulic winch systems can use accumulators and passive heave compensation to form a semi-active system with both an active and a passive component. In such systems the active part will take over when the passive ...

6. Insulation monitoring device - Wikipedia

   en.wikipedia.org/wiki/Insulation_monitoring_device

   An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth.It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 kΩ (sample of IEC standard for medical applications).

7. Electromagnetic shielding - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_shielding

   Electromagnetic shielding cages inside a disassembled mobile phone.. In electrical engineering, electromagnetic shielding is the practice of reducing or redirecting the electromagnetic field (EMF) in a space with barriers made of conductive or magnetic materials.

8. Wire rope spooling technology - Wikipedia

   en.wikipedia.org/wiki/Wire_rope_spooling_technology

   In offshore applications, huge lengths of rope are often housed on drums. The anchor winches on Saipem's Semac 1 pipe laying barge, for example, each hold 2,800 metres of 76mm (3 inch) diameter wire rope in 14 layers. Saipem's Castorone, the world's largest pipe laying vessel uses a wire rope that is 3,850m long and 152mm in diameter. It weighs ...

9. Anchor windlass - Wikipedia

   en.wikipedia.org/wiki/Anchor_windlass

   The anchor is shackled to the anchor cable (US anchor chain), the cable passes up through the hawsepipe, through the pawl, over the windlass gypsy (US wildcat) down through the "spurling pipe" to the chain/cable locker under the forecastle (or poop if at the stern (US fantail)) - the anchor bitts are on a bulkhead in the cable locker and the bitter end of the cable is connected to the bitts ...
