Remontowa wins Croatian ferry design contract

Remontowa Marine Design & Consulting, the Polish ship designer, says it has won the public tender for the development of concept and classification design of ro-ro passenger ship for the largest Croatian ferry operator Jadrolinija.

The ferry will be designated to operate in the Adriatic Sea between the port of Split and the islands of Hvar, Korcula and Vis.

The ship to be designed will carry 2000 passengers and 206 cars, or alternatively 85 cars and 20 trucks. Passenger spaces located on two decks will include a restaurant, bars, buffet, children playroom and designated space for passengers on the open deck.

Transport of passengers between decks will take place also using elevators and escalators. The ship will have two decks designed to carry cars. The bow and stern of the ship will be equipped with ramps to enable efficient loading and unloading

The drive unit will be the four diesel engines, two on each of the two shaft lines. Each shaft line will be equipped with a reduction gearbox, clutch, shaft generator and CP propeller. The ship will have two Backer flap rudders aligned with two propellers.

The ferry will be equipped with one pair of foldable fin stabilizers that ensure the comfort of passengers. She will be also equipped with two bow thrusters to enable precise maneuvering in small and congested ports.

 The vessel will be designed according to the requirements of the CRS (Croatian Register of Shipping) and will meet the latest safety standards in accordance with SOLAS 2009.

Wärtsilä in coalition to promote LNG as a marine fuel

Wärtsilä, the Finnish engineering group,  and other leading marine industry players have formed a coalition, known as SEA/LNG, to accelerate the widespread adoption of liquefied natural gas (LNG) as a marine fuel. The coalition aims to help break down the barriers hindering the global development of LNG in marine applications, thereby improving the environmental performance of the shipping industry.

In addition to Wärtsilä, the other partners in the SEA/LNG coalition include Carnival Corporation, DNV-GL, ENGIE, ENN Group, GE Marine, GTT, Lloyds Register, Mitsubishi, NYK Line, Port of Rotterdam, Qatargas, Shell Downstream and Tote. Each member organization commits mutually agreed human resources, data analysis, and knowledge sharing in support of the SEA/LNG initiatives and activities.

"This is a strong coalition combining the expertise of major fleet owners, classification societies, port facilities, and energy experts. Wärtsilä contributes its vast experience and know-how in gas driven propulsion systems and the entire gas value chain. By working together, we plan to overcome the challenges and speed the general acceptance of LNG. Having been a pioneer in the use of LNG as a marine fuel, and a developer of major technologies facilitating the adoption of LNG fuel, it is natural that Wärtsilä supports wholeheartedly the aims of the SEA/LNG coalition," says Timo Koponen, Vice President, Flow & Gas Solutions, Wärtsilä Marine Solutions.

LNG offers significant environmental advantages for shipping compared to heavy fuel oil (HFO), which remains the predominant fuel used today. By comparison with HFO, NOx emissions are cut by approximately 85%, SOx emissions are almost completely eliminated since natural gas contains no sulphur, and particle production is practically non-existent, thanks to the efficient combustion of natural gas, a fuel with almost no residuals.

The main areas of focus for the coalition include supporting the development of LNG bunkering in major ports, educating stakeholders as to the risks and opportunities in the use of LNG fuel, and developing globally consistent regulations for cleaner shipping fuels.

New cooling technology available for passenger ships

The GadCooler is a new energy efficient cooler for ships. Based on absorption technology it uses waste heat to provide air conditioning cooling and refrigeration for all types of ships. It can handle all or a part of the cooling needs onboard. GadCooler provides major fuel savings for shipowners.

The system uses non-toxic fluids, is practically maintenance-free and can be installed during a normal service docking. The return on investment is short making GadCooler an obvious choice for shipowners when looking for further savings in operational costs.

The GadCooler has been developed by Gadlab Engineering, with patent pending. Heat in the form of steam, rest heat from the engine cooling water or heat from other sources such as boilers is utilized to provide chilled water using a non-toxic absorption fluid as transfer media, replacing the need for onboard cooling compressor capacity.

The system has been successfully applied onboard Eckero Line's cruise ferry Finlandia providing remarkable fuel savings. "GadCooler has fulfilled and even exceeded our expectations in providing cooling at low costs. We expect remarkable savings from the system installed," says Peter Lundberg, Chief Engineer at Finlandia. A GadCooler unit with a capacity of approximately 500 kW provides much of the cooling capacity needed onboard the vessel, operating between Helsinki and Tallinn with up to 2,000 passengers and 650 vehicles onboard.

In summertime cooling is typically a major onboard consumer of fuel. On big cruise ships operating in tropical conditions cooling can consume as much as some 10 MW of power. Normally cooling is provided by using cooling compressors. “GadCooler utilizes existing heat sources for providing cooling in a non-toxic absorption process, resembling the operational principles of gas refrigerators. Only a small amount of energy is needed for the transfer pumps resulting in fuel savings and also in less emissions,” notes Johan Aberg, Naval Architect at Gadlab Engineering. “We have developed the GadCooler to operate in a maritime environment. This requires specific design considerations to be incorporated. The result is an energy saving, efficient, quiet, and vibration free cooler with a short pay-back time for the owner,” summarizes Managing Director Markus Nuotio.

Gadlab Engineering provides the complete system including connection design with existing onboard systems. The GadCooler is fitted with a smart control system which optimizes the cooling efficiency. The GadCooler has received system approval by DNV GL. It is available as one or several units, each with a cooling power of up to 5,000 kW, still providing a practical system size for convenient installation.
