While Tom and Jan (narrowboat-waiouru), are away cruising our boat, and hopefully having a great time, we are busy with preparations for our own winter cruise. Regular readers will know that this year this will again be on Oriana, a P and O cruise ship, on which we will circumnavigate the world between the beginning of January and the middle of April 2012, leaving from, and returning to Southampton. I know that many readers are interested in the specification of Kelly Louise, by the number of views that page gets, so, if anyone is interested, here is the specification of Oriana.
Oriana is 260 metres (853 feet) long, and a beam of 32 metres (105 feet), with a draught of a minimum of 7.9 metres (26 feet), which varies up to 8.2 metres depending on load. She has a maximum passenger capacity of 1,928, and an outside deck area of 9,800 metres square, (105,000 square feet). Power is provided by 4 MAN B&W diesels, generating a total of 47,750 kW, (around 64,000HP), giving her a service speed of 24 knots.
From my own experience of the engines, they are configured in "a father / son arrangement", where there are two pairs of engines, each with one main, (the father), and one secondary (the son). There are then an additional 4 main power generators, and propeller shaft mounted generator / motors. Depending on load, and speed requirement, some or all of the engines can be configured to run consecutively, with spare electricity output from the generators fed to the prop shaft units for absolute maximum speed. When not required, the output from the prop shaft units is fed back into the system.
Our chosen cruise will see us visit 39 ports in 25 countries, now that Libya has been replaced by Capri / Naples and Malta, while they sort themselves out there.
We can't wait!
