Caterpillar Marine to power “Super Tug”

(PresseBox) (Hamburg, ) In recent years, Caterpillar Marine Power Systems (CMPS) has powered countless Offshore Support Vessels (OSV) with both Cat® and MaK brand marine engines. Nonetheless, the latest order from Otto Marine Pte Ltd in Singapore is still remarkable: Two MaK 16 M 32 C marine engines, each of 8,000 kW, will jointly propel a "Super Tug" with more than 250 tons bollard pull. PT. Batamec shipyard in Batam, Indonesia, is working closely with Vik- Sandvik Group, the Norwegian OSV design specialists, to build this multi-functional "VS491 Clean Design" Anchor Handling Tug Supply Vessel (AHTSV).

In addition to the two vee-type M 32 C engines, the CMPS scope of supply for this 90-metre design includes hybrid PTO/PTI gearboxes, 21 metres of shafting and 4.2-metre diameter propellers, all of which are from Scana Volda. The gearboxes provide a lot of flexibility with 4,500 kW PTO (Power Take Off)and 2,000 kW PTI (Power Take In) capability. This setup allows the tug to operate as a diesel-electric vessel when in dynamic positioning mode while using full engine power and electric boost for maximum pull operations.

The MaK VM 32 C engine series comprising 12- and 16- cylinder versions was introduced in 2000. Utilising a bore of 320 mm and a stroke of 420 mm, these diesels cover a power range from 5,760 to 8,000 kW at 720 or 750 rpm. With more than 1,320 engines sold totalling 5,100 MW, the MaK M 32 is recognised for performance and reliability, especially in the OSV market.

The first four VS491 Clean Design vessels have been sold by Otto Marine to Mosvold Supply Ltd of Norway and will be capable of global operation. Newbuildings number one and two will be delivered in October 2009 and June 2010.

Meanwhile, Otto Marine has received further enquiries from customers asking for repeat vessels of similar design.

Michael Petersen, MaK Sales Manager, Caterpillar Marine Asia Pacific, Shanghai said: "This Otto Marine deal ranks among the largest single contracts ever concluded by the team of Caterpillar Marine Asia Pacific in Singapore. Along with many other offshore shipbuilding concerns in Singapore, Indonesia, Malaysia, India and Thailand, we are facing a strong demand for both Cat and MaK main propulsion and generating sets. And I am pretty sure that 2008 will further fuel this demand."
