Roll-on/roll-off carriers (RoRo)
Number of vessels currently operated by Wallenius Wilhelmsen Ocean: 14
The RoRos are the original work horses of the Wallenius Wilhelmsen fleet, optimised to transport High and Heavy (H&H) and static cargo. As they only transport cars as a supplementary cargo, they do not have any dedicated car decks. They are able to carry between 3,000 and 6,500 car units.

With their strong body hull and dead weight ranging from 30,000 to 50,000 tonnes, the RoRos’ “High & Heavy” decks can withstand up to 10 tonnes of pressure per square metre. This means they are perfectly suited to carry heavy cargo like trains, generators and mining equipment. Three or four of the decks on most of Wallenius Wilhelmsen Ocean's RoRo vessels are hoistable: they can be raised or lowered to fit H&H cargo needs.

Example: The Tamerlane
Dead weight: 39,401 metric tonnes
Capacity cars: 5,496
Hoistable decks: 4
Maximum load height: 6.4 metres
Maximum load width: 12 metres
Ramp weight capacity: 320 tonnes

Pure car truck ­carrierS (PCTC)
Number of vessels currently operated by WWL: 31
Wallenius Wilhelmsen Ocean's PCTCs are a type of RoRo vessel with a capacity of 2,000 to 6,000 units of cars and trucks, and a dead weight ranging from 15,000 to 30,000 tonnes. As they carry lighter cargo than the RoRo, the PCTCs have a more slender hull and can take a maximum load on the decks of three tonnes per square metre. Aside from the dedicated car decks on board to carry normal sized cars, there are also hoistable decks that can be adjusted to make space for heavier cargo like trucks, buses, tractors and bulldozers. Some of Wallenius Wilhelmsen Ocean's PCTCs have as many as five or six hoistable decks, able to accommodate load heights of up to seven metres.

Example: The Aida
Dead weight: 22,467 tonnes
Capacity cars: 6,700
Hoistable decks: 5
Maximum load height: 6.5 metres
Maximum load width: 7 metres
Ramp weight capacity: 125 tonnes

Large car truck ­carrierS (LCTC)
Number of vessels currently operated by WWL: 14
A PCTC which is longer than 200 metres or 656 feet is called a large car and truck carrier (LCTC). These seafaring giants have a capacity of 6,000 to 8,000 car units. The world’s first LCTC was Wallenius Wilhelmsen Logistics’s M/V Faust which was delivered in 2007.

Example: The M/V Aniara
Dead weight: 30,383 tonnes
Capacity cars: 7,600
Hoistable decks: 5
Maximum load height: 7.04 metres
Maximum load width: 14.50 metres
Ramp weight capacity: 320 tonnes

More numbers
- The M/V Aniara can carry up to 8,000 cars (RT43). If you put all those cars in a line, it would be 330 kilometres long.
- The capacity deck area is 67,000 m2. That is 42.2 NHL hockey-rinks.

Wallenius Wilhelmsen Ocean measures car capacity in RT43 units. One RT43 unit equals the size of a 1967 Toyota Corona.

Ramp capacity
Ramp capacity is how much weight the ramp can take. It is important because it gives the maximum weight of the cargo unit that can be transported on board the vessel.
