2. 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 ...

3. Heat-shrink tubing - Wikipedia

   en.wikipedia.org/wiki/Heat-shrink_tubing

   Heat-shrink tubing was invented by Raychem Corporation [4] in 1962. [5] It is manufactured from a thermoplastic material such as polyolefin, fluoropolymer (such as FEP, PTFE or Kynar), PVC, neoprene, silicone elastomer or Viton. The process for making heat-shrink tubing is as follows: First the material is chosen based on its properties.

4. 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 ...

5. Cross-linked polyethylene - Wikipedia

   en.wikipedia.org/wiki/Cross-linked_polyethylene

   A cross-linked polyethylene (PEX) pipe. Cross-linked polyethylene, commonly abbreviated PEX, XPE or XLPE, is a form of polyethylene with cross-links.It is used predominantly in building services pipework systems, hydronic radiant heating and cooling systems, domestic water piping, insulation for high tension (high voltage) electrical cables, and baby play mats.

6. Pipe insulation - Wikipedia

   en.wikipedia.org/wiki/Pipe_insulation

   Pipe insulation cannot prevent the freezing of standing water in pipework, but it can increase the time required for freezing to occur—thereby reducing the risk of the water in the pipes freezing. For this reason, it is recommended to insulate pipework at risk of freezing, and local water-supply regulations may require pipe insulation be ...

7. Wireless distribution system - Wikipedia

   en.wikipedia.org/wiki/Wireless_distribution_system

   Network 1: A wireless base station acting as a simple (non-WDS) wireless router. The packet leaves the game console, goes over-the-air to the router, which then transmits it across the WAN. One packet comes back, through the router, which transmits it wirelessly to the game console. Total packets sent over-the-air: 2.

8. 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).

9. Beartrap (hauldown device) - Wikipedia

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

   Constant tension is intentionally maintained on the cable via an automatically-adjusting hydraulic system connected with multiple high-sensitivity tension sensors, and a shock absorption system. [1] Fail-safes are incorporated into the device as well. When the LSO determines that a relatively quiet moment is approaching, they instruct the pilot ...
