Singapore-based Penguin International has selected SCHOTTEL’s Tunnel Thruster STT 51 FP for its Flex-42X series of eight executive fast crew boats.

With a 95 kW electric motor controlled by a variable frequency drive, the STT will be installed in the new vessels being built by the customer’s shipyards in Singapore and Indonesia.

As the vessels are based on a completely re-designed aluminium monohull form, the STTs feature an aluminium tunnel as well as an aluminium lower gear housing. They thus support the vessel’s overall material properties with the advantages of reduced vessel weight and enhanced performance.

Apart from this, the STT’s general low levels of noise and vibration support the vessels’ complete smooth ride, berthing and mooring.

The newly designed mid-size FLEX-42X has an overall length of 42.00m, a moulded breadth of 8.00m, and a design draft of 1.60m. The clear deck cargo area is about 110 m², the fuel capacity is about 80,000 litres.

With a business class seating for 80 passengers plus a crew of 12 the vessel offers more cabin space than any of the other fleet’s crew boats.

They support offshore oil and gas activities, maritime security services and other high-speed transportation requirements for personnel and cargo. Apart from that, they are designed to execute a variety of missions, including security and escort, search and rescue, fire fighting and medivac.
