With a track record in delivery of smaller tugs, Sapor Shipyard of Sibu in Sarawak East Malaysia, is demonstrating an ability to build larger anchor handling tugs to meet the demands of the Malaysian petroleum industry.
Work crews were putting the finishing touches on 121-ft. vessel in early August 2007. With a 34-ft. beam and a molded depth of 16-ft. this is an example of the current crop of smaller AHTs. For its size the Omni Akira has some capabilities centered on the double-drum waterfall winch. The deck winch has a 60-ton single line pull and a 120-ton brake power.
Below decks a half dozen engines keep it all working. A pair of Cummins QSM11-powered 250 kW generators supplies electrical needs that include the electric-drive 3-ton bow thruster
. An 80 kW gen set handles in-harbour loads. A Cummins KTA38 engine powers the boat’s 600 cu. meter per hour fire fighting pump. Main engines are a pair of Cummins KTA50-M2s each delivering 1600 hp at 1800 RPM. This power gives the AHT approximately 42 tons of bollard pull.
Deck equipment includes a three-ton crane and a rescue boat. Accommodation is provided for up to 20 crewmembers.
