Mafamu am'madoko ndi ma boti othamangitsa amayendetsa pafupifupi maola 1,000 - 3,000 pachaka, komabe, pafupifupi 80% ya nthawi yomwe injiniyo imayendetsedwa pansi pa katundu wa 20%. Chifukwa chake, mulingo umodzi wosankha injini yabwino kwambiri pakukoka kwanu ndi: kugawana mphamvu. M'zaka za m'ma 1980, pafupifupi 70% ya ngalawa zokoka zinali ndi injini zothamanga kwambiri. Masiku ano, pafupifupi 90% ya ma tugboat m'madoko ndi malo omwe akumangidwa amagwiritsa ntchito injini zothamanga kwambiri.
Injini yothamanga kwambiri pamadoko ndi ma tugboat opulumutsa
1: Ntchito yofulumira
Injini yothamanga kwambiri imakhala ndi machitidwe ambiri ogwiritsira ntchito, kuyambira osagwira ntchito mpaka kudzaza katundu, kuthamanga kwamphamvu kwambiri, kugwira ntchito bwino komanso kugwira ntchito. Nthawi yothamanga ndi liwiro la ntchito-kuyerekeza kwamphamvu kwambiri (0-100%).
Injini yothamanga kwambiri pamadoko ndi ma tugboat opulumutsa 
2: Kukula ndi kulemera
Ma injini othamanga nthawi zambiri amakhala gawo limodzi mwa magawo atatu a kukula ndi kulemera kwa injini zothamanga kwambiri, ndipo injini zothamanga kwambiri zimakhala zotsika mtengo komanso zosavuta kuziyika.
3: Kugwiritsa ntchito mafuta
Pamene katundu wa injini ndi 50% ~ 70% ndi pamwamba, injini yapakatikati imakhala ndi mafuta ochepa kuposa injini yothamanga kwambiri.
Operational Profile-Port ndi Terminal Tugs
Kugwiritsa Ntchito Mafuta Pachibale 65 T Port ndi Terminal Tugboat Solution
4: Mtengo wogwiritsira ntchito
Zokhudzana ndi ndalama zogwirira ntchito zamainjini othamanga kwambiri komanso apakati pazaka 15, zikuwonekeratu kuti injini zothamanga kwambiri zimakhala ndi zotsika mtengo zogwirira ntchito, ndikupulumutsa 10% mpaka 12%.
Mtengo Wogwira Ntchito
Kapangidwe ka mtengo wogwirira ntchito kwa zaka 15
So amphaka apamwamba-liwiro injinizitha kubweretsa phindu lalikulu pakukokera madoko ndi madoko
Mndandanda wotsatira wa ine ndikutengerani pa nkhani ya makina othamanga kwambiri.
