Our experience includes modernisation of the engine room of a large passanger & car ferry, consisting of replacing two main engines of the B&V type with Zgoda Sulzer 6ZA40S engines, together with foundations and the whole infrastructure (coolers, pumps, pipelines, service tanks, centrifuges, the control and measurement system and remote engine control). All the modernisation works were carried out within 30 work days.
Another of our achievements was an overhaul of the engine room and the on-board 40-tonne crane of a B99 type ship, the Ramiz Gadzijev, in the repair base of an Azerbaijani shipping operator, KMNF, in Baku. It included repair or replacement of all the mechanical devices of the engine room, including replacement of the crankshafts of two 8AL20/24 type main engines and three 6AL20/24 generators. We also replaced the main boiler, most pumps and the starting compressors. The switchboard and the whole control and measurement system, including remote control, were also overhauled. The crane underwent full electric maintenance, including replacement of the magnetic brakes and all the rigging.
Another difficult task was to repair the 100-tonne on-board crane at a crane ship built in Yugoslavia, owned by an Azerbaijani shipping operator KMNF in Baku, the Zulfi Gadzijev, of the K/S 100 type.
The crane had undergone a malfunction of the lift, which required replacement. The owner did not have documentation. The lift was designed and made in Poland. Other mechanisms were repaired under the supervision of Polish specialists. The main hydraulic power unit was replaced following the design of engineers from Bosch-Rexroth, under the supervision of Polish specialists.
Following the well carried out crane repair, we were contracted by the same client to modernise and rebuild a twin crane ship of 100 tonne load carrying capacity, of the K/S 100 type, the Shirvan. The modernisation blueprint was prepared by engineers from Bosch-Rexroth, with our specialists participating. The works included replacement of all the drives and pump aggregates, the entire electrical system and the electronic control and supervision system. The devices were purchased by STr. Under the supervision of our specialists, new devices were installed and the rest of the mechanisms were overhauled.
