Two sets of dual fuel burning main boilers to supply the steam for main turbine, turbo generator, main feed water pump and other steam driven machinery are designed to be capable of burning of heavy fuel oil and also gas fuel by the low duty compressor through boil-off/warm-up heater for the use of boil-off gas.

The 78.6K LPG Carrier Jeanne-Marie was designed for the transportation of liquefied gases such as propane, butane and a mixture of propane and butane. It has a continuous upper deck with aft sunken deck, a raked stem with bulbous bow, a transom stern, a semi-balanced rudder and a fixed pitch propeller directly driven by a slow speed diesel engine. It was built to have four independent self-supporting pris- matic cargo tanks which was designed for a maximum vapor pressure of 0.25 bar, a minimum temperature of -48 °C and a maximum cargo specific gravity of 0.61.

The cargo handling system consists of four externally insulated cargo tanks, loading/discharging and cargo reliquefaction system capable of handling two grade of refrigerated cargoes simultaneously. The engine room is separated from cargo spaces by means of fuel oil tanks.

RoRo

Jean Anne, is the U.S.' first American Flagged,

Jones Act compliant Pure Car Truck Carrier (PCTC). At 579 ft. long and a beam of 102 ft., the vessel is one-half as long as a nuclear aircraft carrier and almost as wide. The vessel can carry up to 4,000 cars on her 10 car decks and has three hoistable decks to carry Over High and Wide (OHW) vehicles such as busses, 18-wheelers and even military vehicles such as M-1 tanks. The OHW vehicles enter the ship on a 100-ton ramp on the aft end of the ship while autos enter from lighter ramps on the sides of the Jean

Anne. VT Halter Marine, Pascagoula, Miss built the $60 million vessel. The building of the ship is quite a milestone for the company, not only because of the

Jean Anne's size and complexity, but problems encountered along the way including a bankruptcy. A sidebar is included detailing the building process.

The vessel is owned by The Pasha Group, Corte

Madera, Calif. and will be operated by Pasha and

Strong Vessel Operators, Stamford, Conn. Jean Anne will be on a route between San Diego, Calif. and three ports in the Hawaiian Islands. With a top speed of 20 knots, the vessel can make a round trip in two weeks including loading in San Diego, unloading and load- ing in three Hawaiian Island ports and return. The ves- sel has a huge amount of space as her 13,000 dead- weight tons testify. Inside the vessel is a lot like being in a 10-story parking garage only this garage travels at 20 knots. Propulsion power for the vessel comes from a MAN B&W 7S50MC-C slow speed diesel supply- ing 14,825 hp at 127 RPM. A 72-ft. shaft connects the engine output to a LIPS 226-in. diameter propeller.

The main engine occupies part of the aft end of the second, third and fourth decks. Three MAN B & W 6L23/30H engines power 920 kW generators and there is a fourth emergency generator rated at 170 kW located on the 11th deck. Both LIPS bow and stern thrusters are a part of the propulsion package to aid in maneuvering such a large ship. To get 4,300 cars, or fewer cars and OHW vehicles requires every square in. of the garage, even the ramps that connect the decks have parked cars when the vessel is full. All but the top or 11th deck is reserved for auto transport. The top deck has a large enclosed space near the bow for such varied purposes as crew staterooms, lounge, refrigerated and dry space for food, galley, mess and a hospital.

Flensburger Schiffbau-Gesellschaft (FSG) has emerged as one of the world's most prolific producers of large RoRo vessels. The latest trailership deliveries to UN RoRo express the strong link forged between

FSG and the Turkish operator. Assigned to the service connecting northern Italy with the Istanbul area, the 29,000-gt Saffet Ulusoy and Marmara are the first pair in a new class of four freight carriers of 3,735 lane-meters, representing the third series of RoRos ordered from Flensburg for UN's eastern

Mediterranean mainline traffic. UN Ro-Ro has made its name in the trailership sector, having created a direct channel for Turkish trade with western Europe, by offering Turkish hauliers an alternative to the over- land route through Bulgaria and Serbia.

Although built to the same main dimensions as the

Und Ege series delivered years ago, the Saffet Ulusoy class signifies a further increase in payload to 3,735 lane-meters, mainly through provision for additional trailers on the weatherdeck. The design also denotes an anticipative approach towards developments in trailer weights. UND was founded by the Turkish

Trucker Association 12 years ago, at a time when all transports went by the Balkan states on land routes to

Central-Europe. Due to the political instabilities and risks involved on the transport routes, however, UND became one of the first shipping companies to imple- ment the "From Road to Sea" concept. Daily services with the very efficient Flensburger RoRo-Freight

Ferries from Istanbul to Trieste were the result. Today the company transports on its ferries in average 200,000 trucks a year.

Samsung in September delivered Maersk

Dunkurque, the first new generation RoRo passen- ger ferry of three vessels for Norfolkline. The vessel was specially designed for operation between Dover and Dunkerque through the English Channel.

The new vessel has a capacity for 780 passengers, up to 200 cars and 120 freight vehicles. New features include separate loading decks for freight and private cars and exclusive facilities, also on separate decks for tourist passengers and freight drivers.

The vessel is built to meet the highest environmen- tal standards and fulfill Lloyds Registers

Environmental Protection notation: no visible smoke from any engines, low noise and vibration impact with satisfaction of PCAC notation. The vessel is equipped with an environmentally friendly waste disposal sys- tem and additional protection around the oil tanks in order to avoid possible oil leaks. Furthermore, the vessel is especially applied redundancy design con- cept of PSMR & ICC on propulsion & control system with separate subdivision of each M/E, A/E and steer- ing gear. Three fixed decks (No. 3, 4, 5) are used for vehicles. Vehicle access of each deck is over bow and stern with total providing 2,900 lane meters for trail- ers and 200 private cars. The lanes are 3.3 m wide with 4.9 m clear height for trailer on deck 3 and deck 4 and 2.4m clear height for private car on deck 5.
