En­sure Oper­a­tional Reli­a­bil­i­ty in Large-Sized Engines

Reli­a­bil­i­ty as a basic re­quire­ment for large en­gines

The de­vel­op­ment of large-sized en­gines fo­cus­es not only on fuel sav­ings but above all on high re­li­a­bil­i­ty. Today, large en­gines are used as ma­rine en­gines or in sta­tion­ary ap­pli­ca­tions as emer­gen­cy power gen­er­a­tors in hos­pi­tals and com­put­er cen­ters. In com­par­i­son to the sta­tion­ary ver­sion, how­ev­er, ship en­gines have ex­treme­ly high de­mands on op­er­a­tional safe­ty and re­li­a­bil­i­ty. Ro­bust en­gines are re­quired that can with­stand all mar­itime ad­ver­si­ties.

Vi­bra­tions in Con­tin­u­ous Oper­a­tion

Chal­lenges in large-sized en­gines

Due to the con­tin­u­ous op­er­a­tion of ma­rine en­gines, great im­por­tance is at­tached to a long ser­vice life of the en­gine in order to keep op­er­at­ing costs as low as pos­si­ble in the long term. Po­ten­tial dam­age to the en­gine, for ex­am­ple due to ro­ta­tion­al vi­bra­tions, re­sults in cost­ly and time-con­sum­ing re­pairs. Equal­ly im­por­tant is a high level of op­er­a­tional safe­ty and re­li­a­bil­i­ty. Even the small­est error can have se­ri­ous con­se­quences. If the en­gine fails, the ship's in­abil­i­ty to ma­neu­ver and loss of sta­bil­i­ty are po­ten­tial con­se­quences. This must be pre­vent­ed. Ro­ta­tion­al vi­bra­tions in all ro­tat­ing com­po­nents, such as crank­shaft and pro­pel­ler shaft, are re­gard­ed as tech­ni­cal­ly par­tic­u­lar­ly rel­e­vant caus­es of po­ten­tial dam­age. Above all, the non cycli­cal ap­pli­ca­tion of force to the stroke move­ment of the pis­ton caus­es an ex­ci­ta­tion of the tor­sion­al vi­bra­tion. The use of flex­i­ble cou­plings is only of lim­it­ed help here.

Mea­sure­ment and Anal­y­sis Tech­nol­o­gy to En­sure Oper­a­tional Safe­ty

Our so­lu­tion for large-sized en­gines

A mon­i­tor­ing sys­tem that iden­ti­fies dan­ger­ous vi­bra­tion con­di­tions ahead of time and ini­ti­ates mea­sures to pro­tect the en­gine be­fore se­ri­ous dam­age oc­curs.

Our sys­tem so­lu­tion, the IFTA Ar­gusOMDS, in com­bi­na­tion with the high-res­o­lu­tion AT2 input mod­ule and the anal­y­sis soft­ware IFTA TrendView­er, of­fers in­di­vid­u­al­ly adapt­able so­lu­tions for the safe­ty of large en­gines. It en­ables angle-re­lat­ed eval­u­a­tions of ro­ta­tion­al and tor­sion­al vi­bra­tions in real-time. Based on ex­cel­lent han­dling of large amounts of data, such as those gen­er­at­ed in long-term mea­sure­ments of con­tin­u­ous motor op­er­a­tion, crit­i­cal vi­bra­tions can be iden­ti­fied and mea­sures taken to pro­tect the motor.
