ALE completed the launch of the first ever submarine to be locally-assembled and launched in South East Asia. The KRI Alugoro (405) submarine was the final vessel to be commissioned as part of a $1.2 billion contract between Daewoo Shipbuilding and Marine Engineering (DSME) and the Indonesian Ministry of Defence for three diesel-electric submarines.
The KASEL 3 submarine, weighing 1,331t, had to be loaded-out onto a barge, towed to a dock, transferred to a floating dock, then a pontoon, before eventually being launched. The complex operation required great accuracy and ALE’s offshore and shipyard experience enabled them to reduce the launch schedule.
One of the project’s challenges was working within the tidal windows available. ALE worked in both day and night shifts to provide the most time-efficient operation, enabling them to complete the manoeuvres more than four days ahead of schedule.
ALE first carried out a weighing of the submarine and then began the transportation from the fabrication shop to the quayside using 60 axle lines of SPMT. There, a barge had been prepared with ALE providing the mooring, winches and ballasting. The 61m submarine was loaded-out and sea-fastened to the deck.
