Don’t miss the How To fea­ture from the ex­perts

Up un­til around the mid 1990s if you worked in the off­shore in­dus­try ~ on ei­ther a ves­sel, rig or a plat­form ~ the tele­vised en­ter­tain­ment avail­able would of­ten have been one TV in the main recre­ation room and a li­brary of well used VHS videos, and lat­terly DVDs. Un­less you worked on a fixed plat­form which was near enough to the coast to re­ceive ter­res­trial ana­logue TV, you would have been un­likely to have seen any live broad­casts. Since then the en­ter­tain­ment sup­plied off­shore has ad­vanced to plasma screen tele­vi­sions in recre­ational ar­eas and many cab­ins, of­fer­ing a wide range of live TV streams, video on de­mand, record­ing ser­vices and wel­fare in­for­ma­tion. Orig­i­nal TV dis­tri­bu­tion sys­tems us­ing head- end satel­lite de­coders started to ap­pear in the late 1990s. The sin­gle out­puts from each de­coder would be con­verted to an ana­logue out­put within the fre­quency range of the TV sets; the dif­fer­ent fre­quen­cies would be com­bined onto one coax­ial cable as if sim­u­lat­ing a ter­res­trial broad­cast of the TV chan­nels. Wood­sons of Aberdeen be­gan to in­stall TVRO ( Tele­vi­sion Re­ceive- Only) sta­bi­lized satel­lite an­ten­nas in 1998 on fish­ing ves­sels as well as oil & gas sup­ply ves­sels. Con­se­quen­tially it has be­come some­thing of an ex­pert of var­i­ous TV prod­ucts and in­stal­la­tions. As the ma­jor­ity of ex­ist­ing cus­tomers op­er­ate in one of the harsh­est en­vi­ron­ments pos­si­ble, the North Sea, they have the ex­pe­ri­ence and back­ground to of­fer the best TVRO sys­tems for satel­lite TV, along with the var­i­ous meth­ods of TV dis­tri­bu­tion through­out the accommodation ar­eas. From ex­pe­ri­ence, when up­grad­ing a TV sys­tem if a new in­fra­struc­ture is to be im­ple­mented, this is best done dur­ing ves­sel or rig re­fits, or fu­ture proofed on a new- build. So in this day and age it is best to think ahead and plan the dis­tri­bu­tion ac­cord­ingly.
