Mphamvu yaikulu ya sitimayo imaperekedwa ndi injini ya mafuta awiri ya gasi ndi dizilo yachilengedwe yothamanga pang'ono kapena yapakatikati, yomwe imatha kusintha mwanzeru pakati pa mafuta ndi gasi kutengera momwe kayendedwe kake kakuyendera. Mu mpweya, kutulutsa kwa sulfure oxides ndi tinthu tating'onoting'ono kumakhala pafupifupi zero. Injiniyo ikukwaniritsa miyezo ya International Maritime Organization (IMO) Tier III yotulutsa mpweya ndipo yakhala ikukonzekera bwino kuyaka kwa madzi a m'mphepete mwa nyanja ku China, zomwe zimapangitsa kuti mpweya ugwiritsidwe ntchito bwino komanso kuonetsetsa kuti mphamvu zake zikugwira ntchito bwino.

Sitimayo ili ndi thanki yamafuta ya LNG yodziyimira payokha ya Type C vacuum-insulated, yopangidwa ndi chitsulo chapadera cha cryogenic, yokhala ndi voliyumu yogwira ntchito yokwaniritsa zofunikira pa kapangidwe kake. Dongosolo Lophatikiza Mafuta a Marine Fuel Gas (FGSS) lofanana limaphatikiza mapampu a cryogenic, ma vaporizer, ma module olamulira kutentha/kupanikizika, ndi unit yowongolera yanzeru. Imatsimikizira kuti mpweya umapezeka bwino ndi kupanikizika ndi kutentha koyenera kupita ku injini yayikulu pansi pa mikhalidwe yosiyanasiyana ya nyanja ndi katundu.

Kapangidwe kake kamaganizira bwino za kapangidwe ka malo ndi malo ofunikira pakulamulira mphamvu yokoka ya sitima ya ro-ro. Thanki yamafuta ya LNG, mapaipi operekera mafuta, ndi malo otetezera amakonzedwa mwanjira yokhazikika komanso yokhazikika. Dongosololi lili ndi magwiridwe antchito osinthika obwezeretsa zinthu kuti zigwirizane ndi momwe zimakhalira zopendekera komanso zogwedezeka, kuonetsetsa kuti mafuta akupezeka nthawi zonse panthawi yokweza/kutsitsa katundu m'galimoto komanso m'malo ovuta a m'nyanja, komanso kugwiritsa ntchito bwino malo ofunika kwambiri.

Sitimayo imakhazikitsa njira yokwanira yotetezera mpweya kutengera mfundo zowongolera mopitirira muyeso komanso kudzipatula kwa zoopsa. Izi zikuphatikizapo kuzindikira kutayikira kwachiwiri kwa thanki yamafuta, kuyang'anira kuchuluka kwa mpweya m'chipinda cha injini, kulumikizana kwa mpweya, ndi njira yozimitsa mwadzidzidzi sitima yonse. Njira yowunikira pakati imapereka chiwonetsero chenicheni cha zinthu zomwe zili ndi mafuta, momwe zida zilili, deta yotulutsa mpweya, komanso imathandizira kusanthula mphamvu moyenera komanso thandizo laukadaulo patali.
