Case study

Europe’s First Major LNG Cruise Dry-Docks: A milestone led by LR's Cruise Center of Expertise (CCoE)

"This achievement was the result of an extensive joint effort to define an approach that satisfied both Lloyd’s Register and Carnival UK objectives of ensuring safe, reliable operations throughout the next survey cycle. The ultimate goal is to leverage the insights gained, embed lessons learned and formalise best practices into future standards for adoption across all vessels with similar systems".

Nick Playle

Refit Project Manager, Carnival UK

Planning Lead Time: LR and Carnival coordinated 18 months in advance to manage complex survey sequences and long-lead spare parts.

Operational Continuity: 50% of the LNG system stayed operational, allowing for safe maintenance during active passenger voyages.

Strategic Sequencing: For Iona, continuous LNG capability was maintained for Norwegian fjord compliance; for Mardi Gras, propulsion lines remained active during the Atlantic transit.

Lloyd’s Register and Stena Line: Pioneering methanol engine retrofits in shipping

Amid the current surge in interest in converting ships to use methanol – with more than 100 ship conversions ordered last year – it is easy to forget that the first methanol conversion occurred nearly a decade ago.

With a decade of experience since the world’s first methanol retrofit, LR offers unrivaled expertise in de-risking ship conversion projects.

From the Stena Germanica to new fleet retrofits, LR provides the classification and technical support to ensure safe, compliant methanol operations.

Decarbonise with confidence. Leverage LR’s deep technical insights and risk-based certification to successfully transition your fleet to methanol.

Fuel for thought: LNG for Cruise

Fuel for Thought: LNG for Cruise provides a focused, up-to-date analysis of Liquefied Natural Gas (LNG) as a marine fuel, examining its role in reducing emissions today while supporting pathways to future decarbonisation. LNG offers immediate emissions benefits compared with conventional fuels, alongside the potential to integrate with onboard carbon capture technologies.

LNG’s Crucial Role: Explore LNG’s impact on the cruise sector, from immediate emission cuts to future decarbonisation pathways.

Ready for Adoption: We assess safety, supply chain maturity, and economic drivers for LNG-fueled newbuilds and retrofits.

Operational Flexibility: Learn how LNG supports sustainability via drydocking upgrades and onboard carbon capture technology.
