Solvang's last new-build, the greenest and most fuel efficient ever
27.01.2012Solvang’s last new-build at Hyundai Heavy Industries (delivery 3’rd quarter 2013) will be one of the most fuel efficient LPG carriers ever built, in addition it is one of the world’s largest ships for transporting liquefied petroleum gas.

Solvang has a 84,000 cbm liquefied petroleum gas (LPG) carrier new-build contracted with Korean shipyard Hyundai Heavy Industries. The vessel will be equipped with the world’s first full scale exhaust gas cleaning system (scrubber); a system that will remove 95% of the Sox and 85 % of the particles. This exhaust gas cleaning system will enable the vessel to operate on one type of fuel (low cost, high quality heavy fuel oil), and therefore avoid the risky fuel changeover operations which is the alternative in 2015, where all vessels operating within Europe and US are forced to use low sulphure fuel (<0,1%S). So the exhaust gas cleaning system gives an environmentally friendly, safe and above all a cost effective vessel.
The decision to go for an exhaust gas cleaning system was made after careful evaluation of possible alternative solutions, such as operating on marine gas oil, LPG and LNG. Where all of these alternatives were found to be either too expensive or not practical with today’s available technology for a long haul LPG carrier. One key factor in the decision to go for an exhaust gas cleaning system is the probability of the new-build operating substantially in, as well as out of an emission control area. All vessels in an emission control area will need to use fuels with a sulphur content of max 0.1%, or opt to clean the engine exhaust of its sulphur oxide content to an equivalent level.
The exhaust gas cleaning is one part of a series of techniques for making the vessel as efficient, economic and as green as possible. Solvang Vessel Performance Monitoring system reveals that our last new-build has approximately 40% lower fuel consumption, and 60% lower NOx emissions than the vessels built 30 years ago, Furthermore the new-build is estimated to have 15% better fuel efficiency compared to similar modern vessels, while the NOx reduction is estimated to around 30% compared to Solvang's most fuel efficient vessel today.
Making Heavy Fuel Oil Clean
Exhaust gas recirculation (EGR) combined with previous measures reduces NOx emissions from heavy fuel oil by up to 80 % in a typical LPG tanker. The concept is a potential game changer for Norwegian domestic shipping.
The greenest and most fuel efficient VLGC ever
Solvang’s new-builds (84k cbm) at Hyundai Heavy Industries are two of the most fuel efficient LPG carriers ever built, in addition they are some of the world’s largest ships for transporting liquefied petroleum gas.
