  • Vessels to be delivered in 2013/14 Ro-Ro vessel built in China for Norwegian Norlines Winner of “Next Generation Shipping Award” 2011

  • Conversions (to LNG propulsion) What needs to be done ? What to chose ? To what cost ? Some examples.
  • What needs to be done ? Feasibility study Age of vessel Technical issues (Space, stability, classification, redesign etc) Timeframe (technical documentation, yard capacity, off-hire) Business case (Capex, Opex, Charter-agreement) Technical agreement Engine type LNG fuel-tank Backup-systems Scope of design-work Yard-work and testing/verification If NOx fund sopport, testing verification period
  • What to chose ? Scrubber, SCR, Low-sulphur, MDO Type of engine Lean burn gas engine Dual fuel engine LNG fuel tank C-type (Pressurized) A-type (Atmospheric pressure) Backup system (PTI)
  • Engines Lean burn gas engines IMO Tier III compliant High efficiency (49%) Low fuel-consumption Good tolerance for low methanenumber Not 1A1 approved (Backup needed) Dual fuel gas engines IMO Tier III compliant Fuel flexibility No need for back-up Complex High maintenance cost Sensitive for methane-number
  • LNG tanks C-type Handles Boil-off Simple system (Coldbox) References as fuel-tank Take space Expensive A-type Space-friendly Less cost Boil-off issue Few references as fuel-tank Need of submerged pumps
  • Backup systems LNG Mechanical with PTI Gas-Electric
  • Cost Between 40 and 65 MNOK Depending on: Size of fuel-tank(s) : 2 * 250 cbm. C-Tank : 16 MNOK Engine type and power: Example : 5 MW engine: 10-15 MNOK New gearbox incl. PTI and HSG : 5 – 10 MNOK Design : 2 – 4 MNOK Yard-work : 10 – 20 MNOK ?
  • Conversion (Case study Pachuca) GL classed Container feeder Built in 2004/2005 8,4 MW Medium speed engine Trade: Netherland, UK, Norway Member of NOx-fund (MS Lyspoint) Subject for NOx-fund support based onCO2 emission (reduction) in Norwegianwaters
  • Conversion (Case study Pachuca) Possible LNG tank installation Vertical to avoid sloosh 2 tanks for stability andredundancy Bunkering available in Norway
  • Conversion (Case study Pachuca) Example of LNG tank sternplaced. MS Høydal
