US-based Tropical Shipping has ordered a complete propulsion package for its newbuiling series at MAN Diesel & Turbo.
The company has ordered 4 × 1,100 TEU vessels for its trades between Florida, the Bahamas and the Caribbean, which will be equipped with an MAN B&W 6S60ME[ds_preview]-C8.5 main engine, complete with TCA66-21 turbocharger and an SCR (Selective Catalytic Reduction) module to achieve Tier III compliance. According to the engine manufacturer, the propulsion package also features 3 × MAN 6L23/30 Holeby GenSets with MAN TCR14 turbochargers, as well as the latest generation of CP propellers, the VBS1550-5 Mk5, which is a five-bladed design combined with the MAN Alpha rudder-bulb concept. Tropical Shipping has also ordered 2 × 300 TEU vessels, each powered by 1 × MAN 27/38 engines, with TCR turbochargers. The new vessels are due to enter service from June 2018 on.
The MAN 23/30 GenSet
MAN says, the 23/30 engine is one of the company`s most successful workhorses, and has a half-century history of operational stability with over 12,000 sales to date. It is optimised for part-load operation, typically at 40-65%, and features an mep that is < 20 bar. »qAs a result, the engine experiences reduced operative stress – compared to its competitors – meaning a decreased demand for spare parts and significantly reduced running costs over its lifetime«, MAN adds.
