MARINE DESIGN the size, but the technical innovations present in this design that will make these ships a real breakthrough for the industry,” said Schramm. “Such highly specialized vessels require a very strong technical partnership and we are looking forward to working together with Jaccar,

Hartmann and HB Hunte.”

The fi ve ECO STAR 85K ethane-fu- elled VLEC-carriers will have a capacity of 85,000 cbm each. The cargo tanks of these fi ve new vessels include another world fi rst – the use of the innovative

Star-Tri-Lobe tanks. These consist of three cylinders combined into one. Due to better utilization of the space in the cargo holds, this results in higher effi - ciency and allows an increase in cargo capacity of nearly 30% over similarly sized vessels with conventional tanks, reducing shipping costs through greater economies of scale.

Electric

Ferry

The fi rst full-electrical passenger ferry in composite is delivered to Ballerina

AB in Stockholm, Sweden.

Faaborg Vaerft A/S delivered the fi rst full-electrical passenger vessel, Sjövä- gen, built in composite materials to the shipping company Ballerina AB in

Stockholm, Sweden. The vessel will operate in the archipelago of Stock- holm where it will transport passengers between the different stops silently and environmentally with its correct propul- sion.

The 24.5-m vessel sailed from Faaborg to Stockholm on its own keel and by its own power where it will start to oper- ate shortly after arrival. Faaborg Vaerft

Technical Solution and Saft have jointly developed, designed and produced this modern vessel.

Sjövägen is designed and approved for 150 passengers. It is ice reinforced, equipped with a double propeller sys- tem, 2 x 160 kW electrical engines for propulsion, 500 kWh battery bank, elec- tro hydraulic steering system, electrical bow thruster and communication and navigation equipment.

Sjövägen is designed so that the pas- sengers board the ship from the bow and from here access to the passenger area is through two automatic glass sliding doors. Access to the ship and the pas- senger area is especially designed for wheelchairs etc. The vessel is designed for two-men operation which will main- ly be from the high placed wheelhouse.

Wilhelmsen Technical Solutions have under the brand name Callenberg deliv- ered the ship’s Electrical Main/Propul- sion Engines, Propulsion Drives, Main

Switchboards 400Vac and 650Vdc,

Battery Chargers and Inverters, Main

Automation System, Shore Connection,

Propulsion Control, Total System Inte- gration for Power Distribution and Pro- pulsion, Detailed Engineering and Soft- ware Development, and Commissioning on site

Saft delivered Sjövägen’s Li-Ion cells with the Saft patented electrochemistry technology Saft Super Phosphat; Battery modules, totally 500 kWh at 650V; Bat- tery management modules with CAN-

Bus communication to the main automa- tion system; and Sheet metal cabinets where battery modules are installed.
