customers can be assured of truly global support, 24 hours a day. PROPULSION SOLUTIONS FOR THE NEW ERA OF SHIPPING Faced by economic challenges, new environmental legislation, and evolving global trade implications, the marine industry has undergone significant changes in recent years. Wärtsilä has been, and remains, at the forefront in developing technologies to meet the new realities faced by ship owners and operators the world over. One word – ‘efficiency’ – sums up Wärtsilä’s approach to developing propulsion technology. By creating solutions that are in themselves efficient, and which can...

While the trend in recent years has been towards ever larger container vessels, smaller ships are still required for the transportation of containers to and from the major container ports. The operating profiles of the large and smaller container vessels are clearly not the same, and the propulsion systems needed for larger ships are somewhat different than for smaller ones. Wärtsilä offers a full range of propulsion options for every size and for every type of operation, with fuel efficiency and environmental compliance always emphasised. Wärtsilä has worked very closely with its container sector...

Oil/Chemical Tanker Vessels BIT VIKING Vessel type Shanghai Edwards Delivery 2007 Converted to dual-fuel: 2011 Scope of supply 2 x Wärtsilä medium-speed dual-fuel main engines 2 x Wärtsilä LNGPacs 2 x Wärtsilä Auxiliary engines 2 x Wärtsilä gearboxes 2 x Wärtsilä CPPs 2 x Wärtsilä PCSs Service speed Product tankers vary greatly in size according to their loading capacity, and are normally fitted with a single screw propulsion system. In most cases 2-stroke main engines are used in combination with an FP propeller. However, smaller sized vessels might have the propulsion system driven by 4-stroke...

Drill Ships Increasing oil prices have triggered the exploration of oil and gas in harsh and/or deep water environments. This has imposed increased demands on the propulsion systems of drill ships designed to operate in these challenging conditions. Dynamic positioning performance is the key aspect, while reliability and transit performance are also high on the agenda. Wärtsilä’s high power steerable thrusters provide the positioning capabilities required by modern drill ships, thanks to the modernized tilted propeller shaft and nozzle. All propulsion solutions need a reliable control system for...

Tugs The most common purpose of tugs is to assist other vessels during docking and harbour manoeuvring. To perform this task effectively they need to be reliable, highly manoeuvrable and powerful. The defining characteristic that determines the tug’s income is its maximum bollard pull, while all capital investment and operational costs need to be as low as possible. Wärtsilä’s steerable and transverse thrusters provide powerful and efficient manoeuvrability. Vessel type Damen Shipyard Gorinchem, The Netherlands Delivery 2013 Scope of supply 2 x Wärtsilä medium-speed main engine 2 x Wärtsilä compact...

Waterjets, which are essentially huge pumps that can be of either axial or mixed-flow design, are used to meet these needs. For high levels of thrust, a waterjet has to generate both high flow and high pressure, and this requires what are known as ‘mixed...

VIKING GRACE Vessel type RoPax Cruise Vessel 57000 GT Viking Line Cruise & Ferry Delivery 2013 Scope of supply 4 x Wärtsilä medium-speed dual-fuel main engines 2 x Wärtsilä FPPs (built-up) Service speed If timetables and cruise schedules are to be met, the reliability and performance of the propulsion equipment is paramount. At the same time, the comfort levels of the passengers on board always need to be a prime consideration. Increasingly also, environmental performance is of high importance as both local and global legislation becomes ever more stringent. Wärtsilä strives to optimise the operational...

Offshore Patrol Vessels (OPVs) Naval and Coastguard OPVs need rapid acceleration capability with a high degree of manoeuvrability in order to effectively carry out their missions. Very often these vessels operate in shallow waters close to shore, for which the underwater propulsion installations must meet specific and challenging parameters. Wärtsilä has an impressive reference list of high speed vessel installations. Its waterjet technology has even been chosen for a large number of naval support vessel programmes for the US Navy. The power density of Wärtsilä waterjets yields higher propulsion...
