The RTW service is a 110 - 120 days roundtrip from Europe to US East Coast, Oceania, South East Asia, Far East, US West Coast, US East Coast across the Atlantic back to Europe.



Major design objectives: Optimum hull shape to give good form stability and low resistance, good transport economy, efficient and safe cargo handling, minimum environmental impact.

General Arrangement
The vessel is arranged with engine room aft, mooring decks forward and aft on deck 5 and wheelhouse forward to give space for weather deck cargo. Accommodation to be arranged for a crew of 36 in two tiers on the weather deck; one for public spaces and offices and one for living quarters to improve rest & recreation for the crew.

Low double bottom construction to reduce vertical centre of gravity of lightship and cargo.

Fuel oil in protected deep tanks forward and aft.

Deck no 5 is watertight to provide a second watertight barrier, in addition to the freeboard deck (deck 4). The hull will be constructed with double ship sides up to deck 5.

Pilot ladder, gangway, bunker station and Rescue boat (only port side) to be arranged in one continuous recess on deck no 5 on each side of the vessel. Free fall lifeboat to be arranged aft, with safe emergency walkway from the accommodation block.

Cargo hold
Cargo hold to be arranged for efficient and safe cargo handling with completely flush bulkheads or horizontal cargo support rails to support efficient stowing of breakbulk cargoes on all decks.

Generally, single row pillars at abt 15 m longitudinal spacing.

6 fixed cargo decks for H&H, NCC and breakbulk,: Deck 1, 2, 3, 4, 5 and 7.

Deck no 1, 2, 3, 4 and 5, including relevant internal ramps, to be strengthened for fork lift operations and roll trailers of varying payload. Main deck to be strengthened for heavy lift trailers including Samson type trailer.

3 hoistable decks for flexibility and maximum utilisation: Deck 4B, 6 and 8. Deck 6 and 8 is intended for cars and constructed with plywood plating to save weight. Although experience with hydraulic jigger winches in use in our present fleet is excellent, electrical winches will be used on the Mark 5 to eliminate the risk of hydraulic oil spills entirely.

Thorough studies of cargoes and trends have helped to determine the clear height of all decks. Part of the main deck will have a higher clear height than previous generations RO/RO ships.

Transverse ventilation of cargo holds to be arranged.

Cargo securing by means of closely spaced circular holes and cloverleaves. Side lashing points arranged on all heavy decks and top lashing points on the main deck to secure high and heavy cargoes.

m/v Faust

Name: m/v Faust
Type: Car Carrier
Lenght: 228 m
Beam: 33 m
Draft: 11.5 m
Deadweight: 30,383 m.t.
GT: 71,583 m.t.
Capacity: 8,000 units
Year: 2007
Speed: 21 kn
Engine: MAN B&W 7S60

The largest Car Carrier in the world is named motor vessel Faust. The ship is one of the interesting engineer outfits. The vessel was built in 2007 in the ship-yard of Daewoo Shipbuilding and Marine Engineering DSME. The ship is sailing under the flag of Sweden and with its deadweight of 30,383 metric tons in maximum draft is the largest car carrier built ever. Well the number looks too low, but car carriers are designed to carry light cargoes, and their freeboards are too big. That is the main reason this one to have so little deadweight. But m/v Faust has not so little measurements. The Gross Tonnage of the vessel is 71,583 metric tons, with a length of 228 meters and a beam of 33 meters. The maximum draft of m/v Faust is 11.5 meters and the Air Draft of the vessel is 52 meters. The capacity of the ship is for nearly 8000 cars, but this large vessel is designed to carry not only cars, but also trucks.

    The vessel Faust is very interesting ship, which is sailing over the all continents. The stern ramp has a width is 9.5 meters and a height of 6.5 me ters. The ramp has a capacity of 240 tones. The m/v Faust has 13 decks, 5 from which are hoistable. The whole capacity area is about 67,300 cubic meters. As I said the vessel can carry not only cars, but also trucks and busses. This is making the work of engineers harder, because the difference inthe weight of cars will make some lift or will make some twist of the construction. The maximum allowed trucks or busses to be carried are 468 and then will have place for nearly 3,484 cars. So large and difficult to be designed vessel needs from strong engine with a lot of power to move is quickly through the water. Vessels from Ro-Ro type, in which are also Car Carriers, needs a lot of speed. The vessel Faust got its speed from a main engine B&W 7S60MC-C. The maximum speed that the vessel reaches is 21 knots, and the crossing speed is about 19 knots.

   
  The call sign of m/v Faust is SLKQ (Sierra Lima Kilo Quebec) and the IMO number is 9332925. The vessel is operated by the ship-owner Wallenius Wilhelmsen Logistics. The ship is very interesting in the engineer’s point of view. This is the main reason to present it to your attention and to explain the general data of it.

The car carrier has beam of 32.26 meters, air draft of 51.96 meters and height to upper deck of 34.70 meters. The ship Oberon is quite large having capacity for 8,000 cars or combination of 3,484 cars and 466 busses or heavy vehicles. The ship has draft 11.30 meters, fully loaded with cargo. These measurements of the ship Oberon are giving deadweight of 30.134 metric tons, while the gross tonnage is 71,673 gross tons and net tonnage is 33,513 net tons. Definitely the car carrier Oberon and her sister ship Aniara are the largest car carriers of the world, having not only the largest capacity, but also largest measurements. And such large vessel cannot be built elsewhere, because of the restrictions in many ship-yards. The shipbuilder, which was able to create such a giant was Daewoo Shipbuilding & Marine Engineering and their ship-yard DSME in Korea. The ship-builder installed on board of the large car carrier strong and reliable main engine of MAN B&W 8S60ME-C7, which is giving 24,560 hp power and ability for the ship to sail with 21 knots.

      The ship Oberon is having 13 cargo decks and cargo volume of 67,000 cubic meters. Five of these cargo decks are movable and strengthened for Roll On � Roll Off cargo. The stern cargo deck is the place, where the ship can be loaded and discharged. The stern deck is having 9.50 meters width and 6.50 meters in height with capacity of 320 tons. The machinery on board of Oberon is consisted of two mooring winches working together or alone and six conventional mooring winches. Two of the winches are placed on the forecastle and four winches on the poop deck. On board there is a provision crane, which is situated on the upper deck with a capacity of five tons. In the tank is provided quality ventilation in case to prevent the cargo from the air and humidity. The air in the ship should be changed 20 times in hour The electricity on board and maneuvering ability is provided by diesel generators STX-MAN-B&W 9SL21/31 with total power of 1,700 kW and shaft generator with power of 1,100 kW. The ship is equipped with emergency diesel generator with power of 215 kW. The high quality engine and generators on board are supported by quality navigation products and 360 degrees wheelhouse design. On board there are two separate ECDIS systems, which is made to automate the work of navigation officers on board and increase their attention to watching and ship maneuvering. On the bridge there is modern Navigational Console, INC, which is having Automated Navigation and Track keeping System, for better steering the course. The communication is ensured by Inmarsat B+C , VHF radio and GMDSS. The car carrier Oberon is really amazing and very interesting in all kind of views. The ship is designed according to latest requirements of IMO and SOLAS, to be safety and environmental.
