Design Challenges
Increased deadweight and lightship weight requirements, yet only a small increase in the principal dimensions compared with the existing vessels on the routes, due to port limitations
Deadweight requirements, nearly 300 tonnes more than existing vessel •LNG Tank (100 tonnes ) • Additional hoistable car deck (70 tonnes ) •Larger bow thrusters to Equipment Requirements: additional weight compared to meet manoeuvring existing vessels requirements • Allowance for equipment for additional passengers • Allowance for additional How to lessen this challenge? Explore possibilities to build passenger lifts Loch Seaforth size vessels, this requires to identify the harbour infrastructure requirements and upgrades required

Why Dual Fuel for Ferries
. The vessels are to be capable of running on dual fuel: . The flexibility of using Marine Gas Oil (MGO) and Liquid Natural Gas (LNG) provide the opportunity to lower emissions and gives greater flexibility over future fuel costs. And allows the vessels to be operated at various ports.
. Using LNG as a fuel offers clear environmental benefits: . The NOx emissions are at least 80% below the current IMO level . The amount of emitted particles are less than 10% compared to a conventional marine diesel engine running on diesel . The SOx emissions are almost negligible
. Further, gas operation generates in general 25-30% lower CO2 emissions compared to diesel operation . However, Methane slip has to be avoided during the bunkering and combustion processes of the engines as this is damaging in the context of greenhouse gases
. Methane is 25 to 28 times more harmful than CO2
. Total CHG CO2 equivalents including contribution from THC is 18 to 20% less than that for HFO
