Gas bunkering doesn’t usually affect the normal operations of LNG fuelled ships. All commercial activities while in port can be performed as usual Gas: a green solution In an era characterised by ever more stringent emission regulations and volatile fuel prices, ship owners and operators are faced with serious challenges. Different authorities are setting environmental requirements aimed at respecting international standards. Nevertheless, at the same time they stress the importance of a localised approach. So, how to comply with new environmental rules and yet maintain cost-efficient operations?...

This feature ensures an additional level of operational safety, not present in a single-fuel installation. A unique feature of Wärtsilä dual-fuel engines is their ability to run on natural gas, marine diesel oil, heavy fuel oil and bio fuels, thus providing maximum flexibility in fuel choice. Outstanding emissions compliancy By switching the main source of power from...

When a vessel is powered by Wartsila DF engines utilising LNG as the primary marine fuel, gas bunkering has no impact on the time spent in port. All commercial activities during the port call can be performed as normal while the LNG tank is, at the same time, being refilled by the LNG carrier. The Wartsila LNG bunker carrier is designed with a diesel-electric/mechanical application based on the Wartsila 20DF engine. The LNG bunker carrier uses...

The Middle East’s very first LNG fuelled tug, currently under construction at Drydocks World, Dubai. consideration becomes even stronger when the operation is influenced by sailing periods spent in Emission Control Areas. In particular, container feeders, ferries and ro-ros represent typical vessel fleets that could be converted to gas operation. Gas offers a simpler solution for new built ships and for retrofitting vessels for a greener tomorrow. The VS 485 MKIII...
Open the catalogue to page 5Marine Installation Features To operate on gas fuel, in addition to the appropriate engines, vessels require onboard gas storage and supply system capabilities. Wartsila can efficiently meet all these needs for gas fuelled propulsion, thus providing a single-interface partnership to ship owners, ship operators and shipyards. Wartsila LNGPac The Wartsila LNGPac™ is a complete fuel gas handling system for LNG fuelled ships. It includes the bunkering station, LNG tank and related process equipment, as well as the control and monitoring system. We offer the LNG fuel system as a stand alone product...

This is the largest passenger vessel in the world operating on LNG fuel. It is equipped with two 200 m3 Wartsila LNGPac systems, including a Wartsila patented solution that utilises the latent heat from the LNG evaporation process for the vessel's HVAC system (air conditioning). This system provides significant energy savings for the whole ship by increasing its total efficiency. Systems integration With more than 20 years of experience, and with more than 1000 gas engines sold...
