Cruise Ship Cabling
The biggest problem we always have to fix on Cruise Ships is from Low-Cost workers doing the cable pulling totally wrong. Budgets have to be met from the dry docks and the cruise lines, yet many of the installs that we have worked on are correcting low-cost unskilled workers trying to install network cabling.
Just a few things we have found over the years:-
Cat5/e cable run of 575ft (328 ft max)
30% of cable installed to one cabinet all over the limit and failed all test.
No sealing of fire penetrations.
Connectors just not right
STP cabling no screen attached
For many years now lots of dry dock contractors use staff with little or no knowledge of working with the high-tech cabling methods that are needed these days. The one line we don’t like or use is “it will work” Low Voltage data communications now is a high tech job, with lots of training and understanding how to do it right, or you the customer will have errors and a slow network.
We use real technicians, not any foreign low-cost worker who has no other skills besides turning up, many times we would catch them cheating, in fact, once we knew something was up in the ceiling, when we checked it out later that night, we found one Cat5/e cut and spliced into two runs in the bar area. The following day the staff captain was informed and dealt with the problem and of course, we fixed it.
Structured Cabling is a Technology
Even pulling the cable now is a complex job with things that the ship engineers would find hard to understand like no zip tie’s the cable, loose lay cabling, and bundle max limits.
All this along with the cruise ship’s extra requirements makes our consulting service a natural requirement for the network and safety of the ship. The days of just letting guys pull cable are gone, modern Cat6/7+ cables have to be treated like fiber during installation.
