A project is underway to explore the feasibility of converting product tankers to shore power in ports. As chemical tankers are required to comply with higher safety standards than many other types of vessels, the project is seen as important in ports’ efforts to expand the use of cold ironing as ports strive to comply with new environmental regulations.


While other segments of the shipping industry have explored the use of shore power, so far its application has been applied primarily to cruise ships and ferries as well as some passenger ships. general load. Recently, a few ports have started to study expansion, for example in Sweden and the port of Gothenburg which supported the first tanker to use battery power for harbor navigation and shore power.


The latest program exploring shore power for chemical tankers is launched at the Port of Rotterdam. Stolt Tankers has signed a Memorandum of Understanding with the Port of Rotterdam Authority and Vopak Botlek to conduct a six-month feasibility study for the use of shore power for chemical tankers calling at Vopak’s Botlek Terminal.


Since chemical tankers are required to comply with higher safety standards than many other types of vessels, Stolt believes the results of the study will be important for the chemical tanker industry as a whole.


“We have identified several vessels that could take part in the trial, which if successful will also offer our vessels calling at ports the option of plugging into electricity from renewable sources,” Lucas said. Vos, president of Stolt Tankers. The aim is that while in port, ships can turn off their diesel generators and connect to shore power, potentially from renewable sources.


The project poses several important technical obstacles, which make it unique, according to the partners. The feasibility study aims to discover effective solutions to these challenges that can be used to form the basis of an agreed international standard.


Installing shore power for chemical tankers will only be a viable solution if the industry can agree on a single standard, says Stolt. Shipowners will need confirmation that their vessels can safely and reliably connect to shore power in multiple ports before investing in the necessary vessel adjustments, so designing a solution is essential. industry standard in partnership with other leading organizations.


“The availability of shore-based electricity for our ships has the potential to significantly reduce the use of onboard diesel generators while ships are in port, resulting in a significant reduction in greenhouse gas emissions,” Vos said. “This supports Stolt Tankers’ ambition to reduce its GHG emissions intensity by at least 50% by 2030 from 2008 levels.


At the end of 2021, Stolt Tankers highlighted that it had already reduced its fuel consumption and resulting CO2 emissions by 6% compared to 2020. Stolt achieved savings on tanker consumption by improving operational efficiency and technique and optimization of the fleet. Speed ​​and trim have been optimized based on weather conditions and improved maintenance schedules, including additional cleaning of the hull and propellers, which has also reduced fuel consumption. In addition, on several ships, Stolt has also installed advanced energy-saving propeller blades.


Industrial suppliers of shore power equipment have reported an upsurge in demand in recent years as more and more ports seek to install the necessary connections to supply shore power. In some ports, for example PortMiami, the implementation of shore power has been slowed by the lack of infrastructure to connect the port to the power grid and power generation capabilities.
