Refit, Conversion and Hybrid Debuts at Fort Lauderdale Put Vessel Lifecycle Choices on Show
Draak, Scintilla Maris and the Pearl 100 Hybrid, all exhibiting from 28 October, show how refit, conversion and hybrid propulsion are shaping superyacht ownership, resale and long-range use.
Measured Exhaust Data Alongside Fuel-Based Estimates: What Method D Means for Shipping’s Carbon Reporting
Everimpact chairman Jan Mattsson argues for adding continuous exhaust measurement to fuel-based estimates. EU MRV already permits it as Method D; any ETS allowance saving depends on estimates overstating actual emissions.
ENX: Lateral's 70 m Concept Designed Around a 60 MWh Battery System
Lateral Naval Architects' ENX concept is designed to run on battery power alone on typical Mediterranean charter itineraries. The published design data, the charging question and what it means for operators.
Circular Economy in Yacht Operations: Material Recovery and Refurbishment as Compliance Strategy
Vessel refurbishment and material reuse emerge as operational compliance pathways under the EU Ship Recycling Regulation, with lifecycle cost and governance implications for owners and operators.
Blue Wake Awards 2026: Independent Validation of Marine Environmental Claims Through Lifecycle Assessment
Monaco Yacht Show's Blue Wake programme validates 60 environmental projects using independent lifecycle assessment and ISO methodology. Winners demonstrate measurable emissions reductions, material circularity, and ecosystem restoration backed by peer-reviewed data.
ICOMIA's Coordinating Role in Marine Sustainability Policy: What Operators Should Verify
ICOMIA's positioning as an industry-wide sustainability convenor raises questions for captains and operators about which environmental claims are backed by regulatory substance versus association messaging.
Wind-Assisted Propulsion Retrofits: What Lloyd's Register's 2024 Report Means for Fleet Decarbonisation Decisions
Lloyd's Register's retrofit report maps four wind-assisted propulsion technologies and exposes a verification gap and 16-yard installation bottleneck that technical managers must factor into compliance and ESG claims.
ICOMIA's Coordinating Role Signals Tighter Alignment Between Industry Standards and EU Marine Regulation
ICOMIA's positioning at the intersection of trade coordination and environmental policy points to consolidating standards that captains and operators must track as RED III and FuelEU Maritime enforcement tightens.
SGMF's Three-Fuel Lifecycle Study Forces a Harder Question on Fuel Procurement
SGMF's completed LNG, ammonia and methanol lifecycle assessments show production pathway, not fuel type, determines emissions performance, reshaping how technical managers must audit and defend fuel contracts.
