Wärtsilä will provide integrated turnkey electrical solutions for four new RoRo ferries being built at the Flensburger Schiffbaugesellschaft (FSG) yard in Germany.

Wärtsilä has been awarded the contract to provide integrated turnkey electrical solutions for four new RoRo ferries being built at the Flensburger Schiffbau-Gesellschaft (FSG) yard in Germany. The electrical systems to be delivered include all products and services available from Wärtsilä SAM Electronics. The vessels are contracted by SIEM RoRo Carriers Ltd., and two will be chartered to Denmark’s DFDS and two to EKOL of Turkey. The contract with Wärtsilä was signed in the second quarter of this year.

The full Wärtsilä scope of supply covers the electrical systems engineering and project management, supply and installation of the cables and equipment, Wärtsilä Nacos Platinum navigation and automation, external and internal communication systems, energy distribution, the lighting system, and the engine control room consoles. The contract started immediately and first equipment is scheduled for summer 2016.

The 11,000 deadweight ferries are 209 metres in length and have cabins for 12 drivers and capacity for 283 trailers.

“We have enjoyed a successful partnership with FSG for more than 20 years, and we are proud that this good cooperation is continued with these four vessels. The success of turnkey system integration depends very much on this kind of close relationship,” says Stephan Kuhn, Vice President, Electrical & Automation, Wärtsilä.

“Wärtsilä SAM Electronics are fully familiar with the products and support required for these vessels, having repeated installations on these RoRo’s for many years. With the full integration and repeat of the systems, we expect an improvement in efficiency and reduction in risk,” says Alex Gregg-Smith, Managing Director of FSG.

WÄRTSILÄ SAM ELECTRONICS

Wärtsilä SAM Electronics is one of the leading system houses for the supply of complete electrical and automation system packages on vessels. In close partnership with shipbuilding yards, the company can be present from the preliminary design stage of projects, combining competent project management with professional cross-system capabilities, and integrating numerous electric and electronic systems to provide a uniform turnkey solution.

Wärtsilä to participate in LNG powered dry bulk carrier project

The supreme efficiency of the Wärtsilä 31 engine makes it a competitive and viable alternative option for equipping future dry bulk carrier vessels with LNG propulsion.
The supreme efficiency of the Wärtsilä 31 engine makes it a competitive and viable alternative option for equipping future dry bulk carrier vessels with LNG propulsion.

Wärtsilä is to team up with an international group of shipping industry companies and organisations in a project to develop a concept for equipping future dry bulk carrier vessels with LNG propulsion.

Project Forward is led by Athens-based Arista Shipping. It began officially in May 2015 with the aim of developing a commercially feasible LNG powered dry bulk carrier design capable of complying with the International Maritime Organization’s (IMO) Energy Efficiency Design Index 2025 standards, as well as with all relevant emission reduction regulations. In addition to Arista Shipping, the other parties involved in the project are Finnish ship designer Deltamarin, the Houston based classification society American Bureau of Shipping (ABS) and GTT, the French LNG membrane containment system designer.

The Wärtsilä 31DF dual-fuel engine is likely to form the basis of the concept’s propulsion system. Introduced in June 2015, the Wärtsilä 31 has been recognised by Guinness World Records as being the world’s most efficient 4-stroke diesel engine. The DF version allows the use of either LNG or conventional marine fuel oils. While 2-stroke engines are the conventional choice for vessels of this type, the supreme efficiency of the Wärtsilä 31 engine makes it a competitive and viable alternative option.

“Wärtsilä has been selected to participate in this important project because of our depth of experience in LNG propulsion solutions, our strong position in 4-stroke engine technology, and in particular because of the state-of-the-art Wärtsilä 31 engine. This engine has not only taken efficiency to a new benchmark level, but in gas-mode is IMO Tier III compliant without the need for any exhaust cleaning systems. We are proud to be a part of this future-looking project, which could eventually be applied equally well to other types and sizes of merchant vessel,” says Aaron Bresnahan, Vice President, Sales, Wärtsilä Marine Solutions.

“Project Forward aims to become a milestone for the shipping industry and in particular for owners and operators of cargo ships. Owners must decide within the next 5-10 years whether gas as fuel is a practical means of compliance with lower emissions standards and this project will enable all of us to understand its feasibility. We welcome Wärtsilä’s involvement, as it is a company with great experience in this field,” says Arista Shipping Principal, Alexander P. Panagopulos.

The project is to be presented as a topic at the Posidonia 2016 conference and exhibition, to be held in Athens, Greece from June 6 to 10.

Wärtsilä has long been a marine industry pioneer in the development of gas and dual-fuel engine technologies. The company has also led the way in offering complete fuel gas handling and storage systems, as well as gas propulsion systems for all types of vessels.

The Wärtsilä 31 engine

The Wärtsilä 31 is the first of a new generation of medium speed engines, designed to set a new benchmark in efficiency and overall emissions performance. It is available in 8 to 16 cylinder configurations and has a power output ranging from 4.2 to 9.8 MW, at 720 and 750 rpm. This 4-stroke engine has the best fuel economy of any engine in its class. At the same time, it maintains outstanding performance across the complete operating range. Its modular design enables a significant reduction in maintenance time and costs, thereby improving power availability and reducing the need for parts.

ULSTEIN INTRODUCES HIGH CAPACITY, HIGH EFFICIENCY CABLE LAY VESSEL

LX109-Ulstein-Cable-Arch-SB

ULSTEIN introduces the LX109 design, a high capacity, highly efficient cable lay vessel with compact dimensions. The completely new, patent pending, ULSTEIN Cable Arch system in combination with open top vessel design results in an unprecedented total of 12,500 t of power cable that can be laid as one single piece.

A unique feature is the ULSTEIN Cable Arch connecting the forward and aft turntables, allowing to load and lay one continuous cable of up to 12,500 ton. This capacity was made possible by positioning the turntables into the hull instead of their conventional location on deck, improving vessel’s stability. A feature also applied by Ulstein on a rock installation vessel currently under construction. This approach resulted in a slim vessel that can transport and lay cable much more efficient than conventional vessel designs with larger beams.

Locating the a-symmetrical bridge aft, with the cable passing underneath, provides clear and unobstructed views on the cable lay work deck and cable stingers aft and the turntables forward. Furthermore the vessel features a large hangar with ROV moonpool and workboat storage. In combination with the well-known X-BOW® and X-STERNTM hull features, this results in a very cost efficient, safe and comfortable platform with superior operational uptime and transit speed compared to more traditional cable lay units.

“With this design we like to bring the cable lay market to the next level,” says Edwin van Leeuwen, Product Management Leader at Ulstein Design & Solutions. “Using the ship and equipment knowledge available in the Ulstein Group, resulted in a revolutionary, truly integrated design, based on existing technologies. By focusing on a dedicated vessel for cable lay projects, we have been able to dramatically improve on project economy, seakeeping behaviour and fuel economy.”
