A tugboat named Transko Sikatan - IMO 9778911 leisurely crossed from the north side to the south side of the harbor, followed by another tugboat of the same type with the number "IMO 9778909". The two shared space on the side of the hull of the LPG tanker named ASIAN GAS II - IMO 9125401 sailing under the Indonesian flag. According to marinetraffic.com, the LPG tanker has specifications of Length Overall (LOA) is 93 meters and her width is 18 meters."
The tanker slowly moved, accompanied by the two tugboats until the tanker's bow pointed towards the harbor exit. A siren sounded, from somewhere, and the two tugboats released the departing LPG Tanker, which moved away from the harbor towards DUMAI port, Malacca Strait, Indonesia.
The two tugboats floated at the harbor entrance, waiting for their next guest named GAS KALIMANTAN to be guided and pushed to the dock of KRUENG GEUKUEH port, Arun LNG Terminal, Lhokseumawe, Aceh.
I captured these views with a Sony A7iii camera combined with a Canon 100-400 lens using Metabone synchronization. Thanks to my friend
