On 31st August, the chemical and product tanker Stena Imperial was named in Savannah, Georgia. The Stena Imperial is a 50,000 DWT MR tanker based on the IMOIIMAX concept, owned by a joint venture of which Stena Bulk and Indonesian Golden Agri Resources (GAR) each own 50 percent.
The vessel is a further development of a well-established and successful concept offering high cargo flexibility and lower fuel consumtion. IMOIIMAX tankers have been designed to transport both vegetable oils, chemicals as well as clean and dirty petroleum products.
Stena Imperial is the third out of ten vessels ordered by Stena Bulk for a total of USD 400 million with delivery to be completed by 2017. The vessels are operated by Stena Weco and trade within the company’s logistical systems, which now will include a fleet of some 60 tankers.
Kari McCormick, wife of Doug McCormick, Commercial Regional Manager, Chevron in Houston, was godmother at the naming ceremony in Savannah yesterday. The captain of Stena Imperial is Vinay Singh. The vessel was delivered from the Chinese shipyard GSI (Guangzhou Shipbuilding International) 1 July and has now arrived in Savannah on the US East Coast with a cargo of palm oil.
“We are very pleased with the performance of the IMOIIMAX tankers delivered so far. They have already fulfilled all our expectations. The configuration of several small tanks provides for considerable flexibility in regards of cargo combination, something that fits very well within our existing global logistical systems. Additionally, innovative technical solutions have, for example, resulted in lower fuel consumption and have also proved to be very effective in conjunction with discharging and tank cleaning”, says Erik Hånell, CEO of Stena Bulk.
The IMOIIMAX concept has been developed by Stena Teknik together with the Chinese shipyard in Guangzhou. The tanker has 18 tanks of the same size, each with a capacity of 3,000 m3, which allows for greater cargo flexibility. A large number of innovative technical solutions have been implemented, which together, when sailing at service speed, result in 10-20% lower fuel consumption compared with other vessels of the same size.
The remaining nine IMOIIMAX tankers are the Stena Impression (owned by Stena Bulk and GAR – delivered in January 2015), the Stena Image (owned by Concordia Maritime – delivered on 8 April, 2015), the Stena Important (Concordia Maritime – delivery set for autumn 2015), the Stena Imperative (Stena Bulk), the Stenaweco Impulse (Stena Weco), the Stena Imagination (Stena Bulk and GAR), the Stena Immortal (Stena Bulk and GAR), the Stena Immaculate (Stena Bulk and GAR) and the Stena Impeccable (Stena Bulk and GAR).
Some of the technical solutions that will result in more energy efficient consumption and greater logistic flexibility:
· Main engine auto-tuning
· More efficient boiler with recovery from multiple heat sources
· Recovery of propeller energy loss
· Aerodynamic design of the accommodation and bridge
· All cargo tanks designed to carry any type of cargo the vessel can transport
· Effective tank-cleansing system
