Representatives from Hapag-Lloyd and Accelleron discussed innovations and challenges in making fleets more environmentally friendly while maintaining operational efficiency. <\/p>\n
Wolfram Guntermann, director of regulatory affairs at Hapag-Lloyd, shared insights from the company\u2019s extensive fleet decarbonization strategy. With over 41 years of experience, Guntermann highlighted initiatives like upgrading propellers and hull modifications to improve hydrodynamics. \u201cReplacing propellers is a key step in our fleet upgrade program,\u201d he noted, explaining that these changes can reduce fuel consumption by 5-8%, a crucial improvement as vessels operate at slower speeds. <\/p>\n
The company is also investing in dual-fuel vessels capable of using greener fuels like methanol and ammonia. Guntermann described the recent christening of a dual-fuel container ship and plans for a fleet of ammonia-ready vessels. However, he stressed that retrofitting older ships remains vital, as not all vessels can be replaced immediately. <\/p>\n
Hapag-Lloyd\u2019s experience with retrofitting the Brussels Express underscored the challenges involved. The process, extended by pandemic-related delays, revealed the logistical complexities and high costs. \u201cIt\u2019s not pocket change,\u201d Guntermann admitted, but the lessons learned have informed subsequent projects. <\/p>\n
Matthias Reichmann, product manager at Accelleron, introduced Engine Part Load Optimisation (EPLO) for two-stroke engines, a simpler, cost-effective retrofitting option. \u201cThe key takeaway is a 3% reduction in fuel consumption and greenhouse gas emissions,\u201d Reichmann stated, emphasising EPLO\u2019s potential for immediate gains. <\/p>\n
The system adapts turbochargers to optimize performance at reduced speeds, aligning with modern operational profiles. Reichmann described it as \u201ca plug-and-play installation,\u201d leveraging parts replacement during routine maintenance to minimise disruptions. He also highlighted EPLO\u2019s competitive payback time, typically under three years. <\/p>\n
Guntermann addressed another pressing issue: end-of-life vessel recycling. He criticised legal uncertainties arising from conflicting frameworks like the Basel and Hong Kong Conventions, which complicate recycling practices. Hapag-Lloyd adheres strictly to the EU Ship Recycling Regulation, working with certified yards in Turkey. Guntermann called for international cooperation, noting an impending surge in vessel retirements. \u201cWe estimate 15,000 ships will need recycling in the coming years, and the current infrastructure is insufficient.\u201d <\/p>\n
Both speakers underscored the need for industry collaboration. Reichmann noted how EPLO complements other measures like propeller upgrades, while Guntermann emphasised using a mix of retrofitting, new builds, and operational changes to reduce emissions. <\/p>\n
The conference highlighted the transformative potential of retrofitting in decarbonising shipping but also underscored the financial, technical, and regulatory challenges involved. As stakeholders innovate and collaborate, these solutions will play a crucial role in achieving the industry\u2019s net-zero goals. <\/p>\n
