English

Vistafjord was completed in April 1973 by Swan Hunter (Wallsend, River Tyne). Vistafjord was 24292grt and carried 830 passengers on Atlantic crossings, 550 when cruising. She was powered by two 9cyl Sulzer diesels totalling 24000shp. In 1980, she and Sagafjord passed to Norwegian American Cruises (NAC), 90% owned by NAL. In 1983, Trafalgar House acquired NAC, and the ships joined the Cunard fleet, Vistafjord retaining her name. In 1999, Cunard renamed the Vistafjord as Caronia. By this time she carried 736 passengers and tonnage had increased to 24492 following additional cabins on the upper deck. Caronia was sold to Saga Cruises, entering service with her former fleet-mate Saga Rose as Saga Ruby in 2005.

Generators

Saga Ruby has 1 emergency and 7 main electrical generators.
The emergency generator is a Caterpillar SR4 producing 275 kW at 440 V.
The main generators consist of 6 Bergen RSGB-8 producing a maximum 690 kW each and 1 Cummins KTA 3067-G producing a maximum 750 kW. The maximum safe working loads are 550 kW for the Bergens, and 400 kW for the Cummins; at this loading the total power is 3700 kW. During cruises in Northern waters, the average daily loading is 2,975 kW. The tropical waters loading of the generators will result in an average fuel consumption of 15.5 tonnes per day of marine gas oil.
The Bergens are numbered :
Starboard Outer is #1, engine serial number #1986.
Starboard Center is #2, engine serial number #1987.
Starboard Inner is #3, engine serial number #1988.
Port Inner is #4, engine serial number #1989.
Port Centre is #5, engine serial number #1990.
Port Outer is #6, engine serial number #1991.
The Cummins engine has a serial number of #33105825.
The power is supplied from the main switchboard to 21 transformers that take the voltage down from 440 V to 120 V for the cabin and public areas.


Air conditioning

Three Carrier 19XL5353306CR (R134a) marine air conditioning units which supplies treated chilled fresh water to 42 air handling units (AHU). The Carrier units each consume 400 kW (at 100%) of electricity for the motors, which results in 1,734 kW (5,917,000 Btu/h) cooling from the plant. The AHU’s provide 14,750,000 cu ft/h (418,000 m3/h) of conditioned air. This relates to 8 air changes per hour in cabins, 15 changes per hour in the public rooms, and 60 changes per hour in the galley.
The engine room inlet fans produce 306,000 m3/h (10,800,000 cu ft/h) and the exhaust fans remove 50,000 m3/h (1,800,000 cu ft/h). The main engines, generators, and boilers use approximately 230,000 m3/h (8,100,000 cu ft/h) of fresh air at full load.

Auxiliary

22 pumps, 11 sea water and 11 fresh water accomplish the cooling for the above units.
The 11 sea water consist of 3 for the main engine cooling system, 3 for the diesel generators, 4 for the air conditioning units, and 1 for the Cummins.
The 11 fresh water consists of 3 for the main engine jacket water, 3 for the diesel generators, 3 for the main engine piston cooling, and 2 for main engine nozzle cooling.

Boilers

SAACKE Built & Commissioned
Steam is supplied at 9 bar (0.90 MPa; 130 psi) (wet) with a total boiler output of 19,300 kg/h (42,500 lb/h).
This is supplied by :
2 Spanner oil–fired Swirlyflow boilers type j.5655/6 producing 11,000 kg/h (24,300 lb/h) using an average of 3 tonnes per day of fuel.
2 main engine Spanner Swirlyflow exhaust gas boilers type J.5657/58 producing 6,200 kg/h (13,700 lb/h).
The steam is used to heat the fuel to a suitable injection temperature, for air conditioning re-heat, and for domestic hot water. The two domestic water heaters are retrofit and are Alpha Laval Plate Heaters type M10-BFG.

Refrigeration

The provision plant is a retrofit with the new R-404a gas. It has two sides—a high temperature (plus boxes) and a low temperature (minus boxes) system. The plus system has a 35 kW (119,000 Btu/h) cooling capacity, and the minus system has a 41 kW (140,000 Btu/h) cooling capacity.
There are 20 ice-producing machines on board, which are capable of producing 9,450 lb (4,290 kg) per day. There are also 471 cabin sized 2.8-or-4-cubic-foot (79 or 110 L) refrigerators on board, 347 in passenger cabins.

Stabilisers

Denny Brown AEG units which have a designation “Swan Hunter Ship 39 Contract”. They take a full load current of 26 kW per main motor, and have a fin length of 15 feet (4.6 m), and are 7 feet (2.1 m) wide.

Water production plant

Three water production plants on board capable of producing 627 tonnes per day. They are the following:
An Atlas-Danmark Distiller AFGU 2SN091 which is a 200 tonne per day unit.
A Matrix Reverse Osmosis 66K SWRO Silver-D which is a 250 tonne per day unit.
A Matrix Reverse Osmosis 44K SWRO Silver D produces 120 tonnes per day.

Steering gear

The Steering Gear was manufactured by AEG is a vane type RDC 630/100 with a Standard Vickers VSG Mark III Pump. It also has an unusual emergency steering pump, which is driven by a pneumatic motor.
