Cruise Industry Developments

Mea Culpa: Biomethanol Will Be A Major Shipping Fuel For week at the end of June, I worked with Dutch transmission operator TenneT on their 2050 Target Grid scenario. With land at an absolute premium — this is a country that builds entire provinces from the sea bed — planning their transmission system and spatial needs is critical. Full article: https://lnkd.in/gmtRiBV8 TenneT's team was impressive, combining expertise in scenario modeling, aerospace engineering, European energy trading, and deep power systems knowledge. Alongside external experts including IPCC Coordinating Lead Author Prof. Heleen de Coninck, former TNO sustainability leader and chemical industry innovator Reinier Grimbergen, and chemical process veteran Paul Martin, we dug into their 2050 scenario, testing assumptions and challenging biases. A major focus was aviation and shipping fuels. While I'd previously assumed shipping would primarily use hydrogenated vegetable oils (HVO), our analysis showed aviation will consistently outbid shipping for this limited resource due to higher margins and strict molecular requirements for jet engines. Consequently, biomethanol will dominate shipping fuel supply. Instead of shipping getting the cheapest low-carbon fuels, aviation will bid them up to be more expensive than biomethanol because the alternative for aviation — synthetic kerosene and other biological processes — will be much more expensive and they need the cheapest molecules that can be turned into biokerosene. Meanwhile, plummeting battery pack costs, now at $51 per kWh in China, mean electrification of ships will extend far beyond inland waterways and short-sea shipping into hybrid transoceanic vessels. Containerized battery exchanges at major canals will become routine, massively cutting the demand for liquid fuels. I underestimated biomethanol's role and electrification's pace. The good news? Global shipping is already moving towards biomethanol with 14% of orders being for dual-fuel methanol + VLSFO vessels, and battery-powered shipping is advancing faster than anyone anticipated. The result is cleaner ports, quieter vessels, and a rapidly decarbonizing maritime sector. To all who saw the merit order implications before I did and tried to tell me, I finally got there. Thank you for your patience in those discussions. Synthetic fuels and direct use of hydrogen are still an economic dead end, of course.

How Can a Cruise Company Lead the Way in Sustainability? 🌊 When you think of cruise ships, sustainability might not be the first thing that comes to mind. But Carnival Corporation’s 2015 Sustainability Report surprised me with its depth and commitment to making a positive impact. 🚢 About Carnival: Carnival Corporation & plc is the world’s largest leisure travel company, operating 10 global cruise brands with 99 ships.

A quick heads-up. Please do repost. The Merchant Shipping (Vessels in Commercial Use for Sport or Pleasure) Regulations 2025 was laid before Parliament yesterday, and has now come into effect. These Regulations revoke and replace the Merchant Shipping (Vessels in Commercial Use for Sport or Pleasure) Regulations 1998, consolidating and updating the requirements for chartering yachts. These new Regulations apply (with some exceptions) to UK-registered yachts and to non-UK vessels operating in the UK. Yachts over 24 metres 'length' (as defined in The Merchant Shipping (Load Line) Regulations, i.e. waterline length), and carrying no more than 12 guests, are subject to Part A of the REG Code, while smaller yachts (with no minimum that I can see) are now subject to the Sport or Pleasure Vessel Code (SPVC). The SPVC creates a single, modern safety and compliance standard - replacing the long-standing patchwork of the Yellow, Blue, Red and Intended Pleasure Vessel Codes, as well as MGN 280. It reflects changes in vessel technology, including advances in construction methods, stability modelling, hybrid and electric propulsion, and contemporary expectations around safety management. The Code enters into force on 12 December 2025 for vessels whose keels are laid from that date, while existing vessels transition at their next renewal examination or within three years, giving operators time to prepare. Practically, this means owners will need to review their current certification, plan for updated surveys, and budget for any additional equipment or modifications required to meet the new standards.

🚢 Could Sharrow Propellers Redefine Cruise Ship Propulsion Efficiency? ⚙️🌊 The cruise industry is evolving fast under the pressure of IMO decarbonization targets, CII rating performance, and the need for energy efficiency without sacrificing power. One technology that is gaining real traction is the Sharrow Propeller, developed with VEEM for inboard propulsion systems. As a Chief Engineer with experience in cruise ship operations and propulsion efficiency strategies, I believe this innovation could become a transformative solution for future cruise fleets. --- 🔧 Why Sharrow Technology Is Different Unlike traditional propellers with open blade tips, Sharrow uses closed-loop blade geometry, eliminating tip vortex losses—one of the major causes of thrust inefficiency, cavitation, and underwater noise. Performance Highlights (based on CFD studies & sea trials): Parameter Improvement Fuel Consumption −10% to −15% Propulsive Efficiency +9% to +20% Cavitation Significantly reduced URN (Underwater Noise) −3 to −6 dB Vibration on Shaft Line Up to −40% Bollard Thrust +18% (better slow-speed maneuverability) --- ✅ Strategic Impact for Cruise Operators ✔ Meets EEXI and CII compliance goals without major redesign ✔ Supports energy saving initiatives and fleet decarbonization plans ✔ Compatible with diesel-electric, LNG and hybrid systems ✔ Potential alignment with DNV SILENT(E) Class noise requirements ✔ Retrofit-ready for existing propulsion lines --- 🎯 Why This Matters for the Cruise Sector Cruise lines are under pressure to improve operational efficiency while enhancing passenger comfort and reducing environmental impact. Sharrow propellers directly deliver: ✅ Lower OPEX ✅ Reduced cavitation damage & maintenance ✅ Increased comfort (lower vibration & structure-borne noise) ✅ Sustainability performance --- This is not just incremental innovation—it's a hydrodynamic redesign with real operational impact. The question is: will the cruise industry adopt it now, or wait until regulation forces it? I’d be very interested to hear from Technical Superintendents, Fleet Managers, Design Engineers, and Marine Directors: 👉 Would you consider this solution for newbuilds or retrofit feasibility studies? --- #CruiseIndustry #MarineEngineering #SharrowPropeller #VEEM #PropulsionEfficiency #NavalArchitecture #SustainableShipping #IMO2030 #EEXI #CII #Decarbonization #MaritimeTechnology #Innovation #ShipDesign #ChiefEngineer

New IMO granularity: more detail, more deadlines, more data.   The IMO’s Marine Environment Protection Committee have recently raised the bar for GHG compliance. Amendments to Appendix IX of MARPOL Annex VI and revised SEEMP Guidelines mean that from 1 January 2026 (or immediately for newbuilds delivered after 1 August 2025), ship owners and operators face new statutory requirements for IMO DCS - with ripple effects on EU MRV, UK MRV and FuelEU.   What changes? Fuel reporting granularity: split by consumer groups (Main Engine, Auxiliary Engine, Boiler, Others) and by “Underway” vs “Not underway”. Voyage event logging: BOSP/EOSP events replace noon-only reporting; berth-to-berth becomes mandatory. Cargo reporting: aligned with IMO/EU frameworks to support transport work calculations. Shore power reporting: kWh received must be logged. These updates demand greater precision and automation. Manual processes will struggle to keep pace. Tools like RINA's Leonardo Emissions and SERTICA Vessel Reporting System are designed to handle this complexity, capturing, validating and reporting data in real time for compliance confidence.   Are you ready for the 2026 deadline? Let’s talk about how automation can make compliance easier.   #GrowWithRINA

Maritime inspections onboard ships are conducted to ensure compliance with international regulations, safety standards, and operational efficiency. These inspections can be categorized into several types: 1. Flag State Inspection (FSI) • Conducted by the ship’s flag state administration or its authorized inspectors. • Ensures compliance with national and international regulations (SOLAS, MARPOL, STCW, etc.). • Includes checking certificates, crew qualifications, safety equipment, and environmental compliance. 2. Port State Control (PSC) Inspection • Conducted by port state authorities when a ship visits a foreign port. • Focuses on verifying compliance with IMO conventions and detecting deficiencies. • Ships with serious violations may be detained until issues are resolved. • Examples: Paris MoU, Tokyo MoU, USCG inspections. 3. Classification Society Surveys • Conducted by a ship’s classification society (e.g., Lloyd’s Register, DNV, ABS). • Ensures the vessel’s structural integrity, machinery, and equipment meet class standards. • Includes annual, intermediate, and special surveys (every 5 years). 4. ISM & ISPS Audits • ISM (International Safety Management) Code Audit: Ensures the ship follows its Safety Management System (SMS). • ISPS (International Ship and Port Facility Security) Code Audit: Checks security measures against threats like piracy and terrorism. • Conducted by flag states, classification societies, or company-appointed auditors. 5. Company Internal Audits • Performed by the ship’s management company to ensure compliance with company policies and international regulations. • Focuses on safety, pollution prevention, crew performance, and maintenance. 6. Pre-Charter / Vetting Inspections • Conducted by charterers, oil majors, or third-party inspectors before hiring a vessel. • Common for tankers (SIRE inspections) and bulk carriers (RightShip inspections). • Ensures the ship meets safety, operational, and environmental standards. 7. Cargo Inspections • Conducted by cargo surveyors (e.g., Lloyd’s Register, SGS, Bureau Veritas). • Includes checking cargo condition, stowage, securing, and compliance with international regulations (e.g., IMDG Code for dangerous goods). 8. Environmental Inspections (MARPOL Compliance) • Ensures compliance with MARPOL (pollution prevention regulations). • Checks waste management, oily water separators, sewage treatment, and emissions (EEDI, CII). • May be carried out by PSC, flag state, or environmental agencies. 9. Health & Sanitation Inspections • Conducted by port health authorities or PSC. • Ensures compliance with WHO’s International Health Regulations (IHR). • Checks water quality, food safety, pest control, and hygiene conditions onboard. 10. Dry Dock & Special Surveys • Required every 5 years as part of classification society rules. • Includes hull inspections, machinery overhauls, and structural repairs.

Charting a Course to Decarbonization: New LCA Explores Green Maritime Fuels Excited to share this Life Cycle Assessment (LCA) report on e-/bio-methanol and e-/grey-/blue-ammonia as sustainable marine fuels. Commissioned by CMA CGM and conducted by IFP Energies Nouvelles, this study provides a comprehensive analysis of the potential of these fuels to decarbonize the shipping industry. Key takeaways: 1️⃣ E-methanol: Highly effective in reducing maritime GHG emissions, especially when renewable electricity powers electrolysis and carbon capture heat needs are covered by sustainable sources. Location matters! Proximity to bunkering hubs minimizes transport emissions and makes a significant difference. 2️⃣ Bio-methanol: Another strong contender, demonstrating substantial GHG emission reductions. Sustainable biomass supply and minimizing transport distances are key to maximizing its potential. Waste wood-derived bio-methanol shows even greater promise than that from farmed wood, thanks to lower land use emissions. 3️⃣ E-ammonia: A viable option for decarbonization, but requires further optimization of engine technology and vessel architecture to improve efficiency and reduce emissions, especially nitrous oxide. Similar to e-methanol, locating production near bunkering sites is essential. 4️⃣ Blue ammonia: Currently not a feasible solution for deep decarbonization due to the high GHG intensity of methane extraction. Improvements in the natural gas supply chain and potentially blending with biomethane could enhance its future potential. 5️⃣ Grey ammonia: Currently not a viable option for deep decarbonization. Challenges and Opportunities: ✴️ The feasibility of large-scale e-methanol production hinges on the availability of biogenic CO2. For e-ammonia, optimizing engine efficiency and minimizing pilot fuel use are crucial for maximizing its decarbonization impact. ✴️ Scaling bio-methanol production requires a secure and sustainable supply of wood and wood waste, balancing fuel needs with other demands for biomass. ✴️ Building out the necessary infrastructure for producing, storing, and bunkering alternative fuels is essential, particularly near key ports. This presents significant opportunities for investment and collaboration. #Maritime #Decarbonization #LCA #eFuels #Methanol #Ammonia #Sustainability #Shipping #CMACGM #IMO
