History
The ships were built at the Japanese shipyard Saiki Heavy Industries Co. in Saiki. The first ship of the series was ordered on October 28, 2002. Even before its keel-laying in 2004, two more units were ordered on 30 June 2003. Three more units were ordered on 18 August 2006 in the year after the delivery of the third ship of the series.

The ships will be used worldwide by United Bulk Carriers in Wayne, Pennsylvania. They are managed by Intership Navigation Co. in Limassol, Cyprus. Both companies belong to the Hartmann Group, which has its headquarters in Leer (East Frisia).

Description
The ships are powered by a Mitsubishi diesel engine (type: 6UEC52LS) with an output of 7,980 kW. The engine acts on a fixed propeller. The cruising speed of the ships is about 15 kn. Two Yanmar diesel engines (type: 6N18AL-UV) with 550 kW power are available for power generation. Furthermore, an emergency generator driven by an MAN diesel engine with a power of 250 kW was installed (here the engine types D2866 LXE30 and D2866 LXE20 were used).

The ships have six box-shaped holds. Cargo space 1 is 20.8 m long. It is 20.0 m wide in the rear area and tapers forward to 12.0 m. The cargo spaces 2 and 4 are each 25.6 m long, the cargo spaces 3 and 5 are each 26.4 m long and 24.0 m wide. Cargo space 6 is 17.6 m long. It is 24 m wide in the front area and tapers backwards to 10.4 m. The cargo spaces are each 15.3 m high and have a bit of understorage towards the front and rear. The cargo spaces are closed by hydraulically operated folding hatch covers. The hatch dimensions of cargo space 1 are 11,2 × 20,0 m, for cargo spaces 2 to 4 it is 21,6 × 24,0 m and for cargo space 6 it is 14,4 × 24,0 m. Three hydraulic ship cranes are available for cargo handling. These are located between Luke 1 and 2, 3 and 4 as well as 5 and 6. The cranes can each lift 36 t. The ships are equipped with three grippers, each with a capacity of 12 m3, for handling bulk goods.

The ships are prepared for transporting containers on deck. On Luke 1, eight TEU can be loaded side by side and two layers on top of each other. On Luke 2, ten TEUs can be placed next to each other and three TEUs one behind the other in two to three layers. On Luke 3 and 4, ten TEUs can be loaded next to each other and three TEUs can be loaded one after the other three layers, on Luke 5 there are ten TEUs next to each other and three TEUs one after the other with four layers one above the other. On Luke 6, ten TEUs can be placed next to each other and two TEUs in succession, which can be loaded four layers one above the other. In addition, a TEU can each have three or four layers high transversely
