In March and April we have been working in a 54 m, built in 2006 at the Turkish shipyard Turquoise Yachts. This yacht is in Barcelona to carry out an extensive refit, and at Medenisa we have taken care, obviously, of the electronics.

For this project we have carried out several tests to electronic equipment on board; to that already installed, but to some brand new parts which have upgraded the existing ones. We talk about this kind of tests a few weeks ago. The tests are important for new equipment as well, in order to check that the equipment will be connected to a network that is working properly. For this yacht we have installed:

  • Two big domes with antennas for satellite TV
  • Two Inmarsat C antennas
  • Two 4G antennas
  • A Navtex system, for reception of weather and navigation warnings
  • A WiFi access point, for distribution of wireless signal throughout the yacht

What makes this project interesting is the fact that it was the client who directly bought the equipment, and we have carried out the installation. This is quite usual nowadays: the manufacturers give recommended prices, and a lot of dealers sell them with good discounts, particularly online. Hence a lot of people buy the products directly, saving a few bucks, and contact a technician just for the installation, if at all.

Incompatibility problems between pieces of equipment seldom arise but, when we are given new equipment to install, sometimes we can find some problems. Why? Mainly because it’s difficult to tell apart the installation works related to the dealer, from what is purely “physical” installation of any other element related to the equipment. In this particular project we had to solve the following problems:

  1. The cabling of the TV antennas were supplied by the dealer, not us. Those cables had to be run to the radio station, except one of them, which had to run to a multiswitch (a device for distribution of the signal to several receivers). But the exact location of the multiswitch was yet to be defined, hence the works may have suffered some delays, and moreover leaving the running of that cable for the final stage of the project might have caused a non-optimal layout of the cabling
  2. The installation of the BDU (Below Deck Unit, the device that is directly connected to the antenna) was responsibility of the dealer, as well. Again, this can cause delays, and prevents us from finding the best layout for the cabling
  3. The drawing of the new antennas arrangement was made by the dealer. Unfortunately too often the dealer is more a commercial than a technician, and many times he has not the time to go on board to check in situ where the installation is to be made; this may result in a poor location of the antennas, thus creating shadows and poor reception
  4. Nobody had studied how to solve the running of the cables through the mast, mainly the points where the cable enters the mast, and where it enters the yacht’s superstructure. These arrangements can be more easily made, and better, if the dealer and the installer are the same

A few weeks ago, at the end of this article, we told you about all the aspects included in the installation of electronic equipment: the first look into the project (preliminary design, location of the equipment, power consumption, design of the network…), installation of the cabling, antennas and transducers, installation of the equipment, set-up and tests. For a swift and clean job (hence with lesser costs for the client) a very good coordination between all those jobs is very important. But this is not always easy when several companies are involved in the same project.
