The tanker valued at 40.8 million euros, intended for the transport of chemical and oil products, is 184 metres long, 32.20 metres wide and has a load-bearing capacity of 49,500 metric tons. It is powered by a MAN B & W with a capacity of 8000 kW, which can reach the speed of 14.5 knots. The ribbon was cut by the owner and the Management Board member Danko Končar, who stated that the Trogir Maritime company was leasing these tankers to ship operators at a daily rate of between 7,500 and 9,500 dollars.
Federal Mogul has developed the cooling of pistons, which enables them to operate at an engine temperature more than 100°C higher than the current limit. Keri Westbrooke, Engineering and Technology Director at Federal Mogul, explains that this enables an increase of 5 % in energy efficiency. The company believes that it will start the mass production of such pistons by 2021.
The Wärtsilä 31, an engine which was presented last year, is the most efficient four-stroke diesel engine in the world. After being entered into the Guinness Book of Records, it has received the Marine Engines Award.
Since the engine is manufactured in three versions, several types of fuel may be used for it, from light to heavy diesel fuels of different quality. It is intended to be a driving engine for ships which require a power of approximately 4.2 to 9.8 MW. Another advantage is that it requires maintenance every 8000 hours, as opposed to other marine engines, which require maintenance already after 2000 hours.
The goal of the GreenPilot project is to demonstrate the benefits of methanol, which could be used for commercial purposes, as marine fuel, as well as in recreational boats. The scientific and technological project goals are to demonstrate that this fuel can match the other types in terms of power usability, as well as to show its positive impact on the environment. The project was initiated by the state authority called the Swedish Maritime Administration and the Methanol Institute organisation, as a part of the SUMMETH (Sustainable Marine Methanol) programme, with the plan of testing three pilot ships with engines of a 450 kW capacity in the course of the next year. An overview of the interests of global methanol producers for marine fuel was presented at a conference held in mid-June. The Stena Lines company has so far received six international awards for the operation and conversion of the Stena Germanica ferry, with three out of a total of four Wartsila engines powered by methanol, whereas the modification of the fourth one is planned in September this year. The modifications and the use of methanol as the primary fuel will reduce the emissions of sulphur by 99 %, nitrogen oxide by 60 %, fine particles by 95 % and CO2 by 25 %.
The companies China State Shipbuilding Corporation (CSSC) and Wärtsilä have announced that Wärtsilä has transferred its share of 30 % in the Winterthur Gas & Diesel (WinGD) company to CSSC, one of the largest shipping conglomerates in China, after which CSSC has gained full ownership of WinGD. WinGD is seated in Winterthur in Switzerland and is one of the earliest representatives of diesel technology, having started the development of large internal combustion engines in 1898 under the name "Sulzer". As an independent international company, WinGD will continue to develop its portfolio of low-speed two-stroke marine engines and cooperate with the services network of the Wärtsilä corporation for the purpose of providing post-purchase support services to buyers.
In December last year, the MAN company presented the last generation of serial six-cylinder engines for working ships. The first engine produced, MAN D2676 LE443, with a capacity of 537 kW (730 HP) at 2300 revolutions per minute, and a cylinder capacity of 12.4 l is intended for use on a new ship for salmon hunting, the LT32 Gilnetter built in the Mavrik Marine shipyard in the state of Washington. The new design of the LT32 ship is adapted for navigation in the shallow waters of the Bristol Bay in Alaska, an advantage in which is ensured by the weight of the D2676 engine, whose dry mass is 1200 kg, that is, 105 kg less than that of the older type, MAN D2876, while its other key advantages include low fuel consumption and quiet operation. The first voyage of the ship is scheduled for late autumn this year.
