The Evergreen Group
’s S-series vessels are built with the standard exceed all national and international regulations regarding environmental protection. In recognition of the ships’ green credentials, Ever Superb, the fifth in the series of vessels to enter service, was awarded Ship of the Year 2006 by Lloyd’s List Maritime Asia.
The S-series vessels incorporate design features such as double-skinned hulls and fuel oil tanks located
in protected locations within the transverse bulkhead spaces, thus minimizing the risk of oil pollution. A high capacity oily water separator enables the oil content of waste water to be reduced to just 15 ppm while much larger separated bilge oil and bilge holding tanks provide more storage capacity, enabling the vessels to avoid any discharge when sailing in sensitive areas and to maximize the amount of waste that can be held for ultimate disposal in specialised shore facilities. Similar arrangements have been made for handling sewage, grey water and cargo hold bilges when the vessels are in port or close to shore, while the ships also incorporate ‘cold-ironing’ – the ability to shut down all shipboard generators and switch to shore-based electricity supplies while in port.
With an overall length of 300 metres and a beam of 42.8 metres, the S-series vessels are able to carry containers 17 rows across on deck and 15 rows across below deck. They have a deadweight of 78,700 tons on a service draft of 14.2 metres. Each vessel has a single 10-cylinder Mitsubishi (MBI.F)
Sulzer 10RTA96C main engine developing 74,700bhp (54,900KW) to provide for a service speed of 25.3 knots.
The carriage of temperature-controlled containers, an increasingly important revenue source, is made possible with the provision of 839 reefer plugs.
