The 2 LNG-fueled icebreaking RO/ROs on order at China’s Yantai CIMC Raffles shipyard (see earlier tale) will certainly each have GUY Cryo LNG fuel gas supply systems (FGSS) as well as 2 GUY 9L28/32DF dual-fuel supporting engines.
The 242 meter long ships are being developed for Sweden’s Wallenius SOL as well as will certainly be the biggest vessels so far to satisfy the Finnish/Swedish ice course 1A Super criterion, making certain year-round solution in the icy Gulf of Bothnia.
They will certainly have a cruising rate of 20 knots as well as an ability of 5,800 lane meters. Delivery of the vessels is set up for 2021 as well as the order consists of a choice for 2 more vessels.
Wallenius SOL is a delivery line developed by Wallenius Lines as well as Svenska Orient Linien (SOL).
Louise Andersson, Head of GUY Cryo, stated: “These RO/ROs will operate in a sensitive, sulfur-emission-control area in harsh winter conditions where a reliable LNG fuel-gas supply system is of the utmost importance. We are very pleased that both shipyard and shipowner trust us to deliver the fuel-gas supply system for such unique vessels.”
GUY Cryo’s extent of supply for the vessel covers:
- 2 × 685 cu.m vacuum cleaner containers consisting of storage tank link rooms (TCSs) with LNG gas pumps
- shelter terminals with an ability of 500 m3/h
- automation, emergency situation shut-down as well as gas-detection systems.
Under- deck installed containers with air locks permit the quantity of fresh air drew right into the storage tank spaces to be minimized to a minimum. This is a vital factor to consider in the hard winter season problems the ships are readied to run in, where the quantity of cool air in the vessels requires to be maintained to a minimum.
Environmental advantages
The brand-new vessels will certainly bring several ecological advantages compared to conventional, heavy-fuel ships consisting of minimized gas intakes as well as reduced exhausts:
- 50% gas intake per tonne-km many thanks to bigger vessels, much more reliable engines as well as ship style
- 60% reduction in exhausts of greenhouse gases per carried system in CARBON DIOXIDE matchings
- 98% reduction in sulphur dioxide (SOx) exhausts
- 85% reduction in nitrogen oxides (NOx)
- 95% reduction in particle exhausts.
