The maritime industry is embracing wind-assisted propulsion as a means to reduce emissions and achieve sustainability goals. In a recent webinar, experts discussed solutions tailored for bulk carriers, addressing stability, performance and retrofitting challenges
Speaking at the Blue WASP-sponsored Harnessing wind propulsion for bulk carriers webinar, DNV senior principal engineer Hasso Hoffmeister highlighted the growing interest in wind propulsion for reducing emissions.
He said, "Wind propulsion falls in the category of energy harvesting technologies... suitable for being retrofitted on existing ships or equipped on newbuilds."
Mr Hoffmeister pointed out challenges associated with different ship types, but noted bulk carriers have favourable conditions for integration.
The webinar addressed concerns regarding stability and performance.
MARIN senior project manager, manoeuvring knowledge co-ordinator Rogier Eggers lay emphasis on the importance of assessing performance and compliance.
He stressed, "Modelling various bulk carrier types and routes is crucial... to identify potential impacts on stability and ensure optimal performance."
Mr Eggers highlighted the need for comprehensive modelling to evaluate different bulk carrier types and routes.
Assessing feasibility and retrofitting, Blue WASP Marine co-founder Giovanni Bordogna discussed the feasibility of retrofitting wind propulsion systems on bulk carriers. He said, "Our holistic approach analyses the impact on vessel performance, fuel savings and compliance."
Mr Bordogna stressed the importance of considering aerodynamics and hydrodynamics for optimal system integration.
Regarding efficient solutions, GT Green Technologies founder George Thompson presented compact wind propulsion solutions suitable for bulk carriers with restricted deck space. He showcased innovative systems capable of generating significant thrust from small units, stating, "Our mission is to provide propulsion to vessels even with the most restricted deck layouts." Mr Thompson noted the importance of feasibility studies and vessel modifications to ensure safe and efficient integration.
Any solution will require certification, with Mr Hoffmeister discussing certification and regulatory aspects, noting the need for industry standards. "Regulators must keep up with developments... to ensure safety and compliance." Mr Hoffmeister emphasised the role of classification societies in facilitating the adoption of wind propulsion systems while ensuring safety and compliance.
In conclusion, the Harnessing wind propulsion for bulk carriers webinar shows wind-assisted propulsion holds immense potential for reducing emissions and improving sustainability in the maritime industry.
With tailored solutions for bulk carriers and careful consideration of stability, performance and regulatory requirements, the adoption of wind-propulsion systems is poised to accelerate. Collaboration between industry stakeholders, rigorous testing, and adherence to standards will drive the successful integration of wind propulsion technology, ushering in a new era of sustainable shipping.
