Methods and systems for efficient installation of cables in watercraft
View Patent ↗The present application is directed towards systems and methods for efficient installation of optical and electrical cable in watercraft. A manufacturer may terminate one end of a cable in a location removed from the watercraft, allowing use of automated cable termination machines for efficiency and consistency of terminations. The single-terminated cable may then be brought to the watercraft and installed by pulling or routing the unterminated end through ductwork and pipes, watertight bulkhead throughways, and cable trays and ladders as necessary, prior to termination. Accordingly, more difficult and expensive on-site labor is reduced, and reliability is greatly increased. Furthermore, many cable tests that require termination but cannot be executed post-installation can be performed prior to installation, to ensure that at least the first termination, performed off-site, is error-free, reducing later troubleshooting and further increasing installation efficiency.
1. A method, comprising:
providing a cable;
attaching a termination at a first end of the cable at a location different from a watercraft; and
supplying the cable unconnected at either end for installation onto the watercraft with the termination attached at the first unconnected end of the cable and a second unconnected end of the cable being non-terminated such that the non-terminated second end is routable through a throughway on the watercraft, wherein the cable is configured for installation on the watercraft to connect and provide a communication path between a plurality of components of the watercraft.
2. The method of claim 1 , further comprising testing the cable prior to supplying the cable for installation onto the watercraft.
3. The method of claim 1 , further comprising:
installing the cable onto the watercraft through the throughway; and
installing a termination onto the second end of the installed cable.
4. The method of claim 3 , wherein the throughway is a multi-cable throughway in a watertight bulkhead of the watercraft.
5. The method of claim 3 , wherein the installing the cable onto the watercraft includes routing the cable through a plurality of watertight compartments.
6. The method of claim 1 , wherein the cable is an optical fiber cable.
7. The method of claim 2 , wherein the testing of the cable includes sending a known amount of light through the first end of the cable or the second end of the cable, the light traveling via optical fibers of the cable.
8. The method of claim 7 , wherein the testing of the cable further includes measuring an amount of light exiting the end of the cable opposite the end through which the known amount of light is sent.
9. The method of claim 2 , wherein the testing of the cable includes performing a measurement via an optical time domain reflectometer.
10. The method of claim 1 , further comprising:
prior to supplying the cable for installation onto the watercraft, attaching a termination to a second end of the watercraft;
after attaching the termination to the second end of the cable and prior to supplying the cable for installation onto the watercraft, testing the cable; and
after testing the cable, removing the termination from the second end of the cable.
11. The method of claim 1 , further comprising:
forming the cable by cutting a length of cable that is longer than the cable; and
prior to forming the cable, testing the length of cable that is longer than the cable.
12. A method for installation of cable into a watercraft, the method comprising:
providing a cable with a first end and a second end;
at a location different from a watercraft, installing a termination at the first end of the cable and a termination at the second end of the cable;
cutting the cable at a location between the first and second ends to form first and second cable sections each having a terminated first end and a non-terminated second end; and
supplying at least the first cable section having the terminated first end and the non-terminated second end for installation onto the watercraft, wherein the cable is configured for installation on the watercraft to connect and provide a communication path between a plurality of components of the watercraft, the at least the first cable section being supplied with the terminated first end unconnected and the non-terminated second end unconnected.
13. The method of claim 12 , further comprising:
installing the first cable section onto the watercraft; and
installing a termination onto the second end of the installed first cable section at the watercraft.
14. The method of claim 12 , further comprising:
providing the second cable section, having the terminated first end and the non-terminated second end, for installation onto the watercraft.
15. The method of claim 14 , further comprising:
installing the first cable section onto the watercraft; and
installing a termination onto the second end of the installed second cable section at the watercraft.
