The team, composed of owner Mr. H. Darmansyah, naval architect Surjo Adji and yard manager Heri Nurcahyono, has built the Muji Rahayu Shipyard into a major player amongst Asian boat builders The yard is located near Samarinda in East Kalimantan, Indonesia. (see Google Earth "Samarinda" lat=-0.502183, lon=117.153801). In mid-February they had more than 15 vessels nearing completion. But more than tugs ware under construction. The steel framework for huge covered areas was being assembled so that work could proceed more easily in the rainy season. In other parts of the yard concrete abutments were being built for fitting out piers. A new office building had recently been built as well. This is clearly a yard that is looking to be around for the long term and it is well on the way to becoming an efficient tidy work area.

The current crop of boats under construction will be delivering in the coming months. On the 16th of March 2008 the yard will begin cutting steel for a new batch of nine vessels with more to follow. These will include five tugs to a proven design by Adji for a 29.85 by 9-meter tug. The tugs will have a design draft of 3.6 meters on a 4-meter molded depth. Main engines will be a pair of Cummins KTA38-M2 diesels each delivering 1200 hp into Twin Disc MG5321 DC marine gears with 5.96:1 ratios. The tugs will be fitted with 4-blade 2-meter propellers in nozzles to give them a light speed of about 12 knots and an estimated bollard pull of approximately 35 tons.
