Acta Marine on Thursday (1 October) celebrated the christening of methanol dual-fuel vessel Acta Hercules during a festive ceremony attended by its stakeholders, clients, business partners, and colleagues of the company.
Equipped with methanol dual-fuel engines and an advanced battery energy storage system, Acta Hercules reflects Acta Marine’s ambition to continuously improve the sustainability and efficiency of its fleet.
The event marked an important milestone in Acta Marine’s ongoing fleet expansion programme and its continued commitment to supporting the offshore wind and wider energy sectors.
The ceremony brought together many of the people and organisations involved in the development, construction, and delivery of Acta Hercules. Guests gathered in IJmuiden to witness the traditional christening and official naming of the vessel, celebrating the collaboration and expertise that contributed to bringing the project to life.
“Today marks a proud milestone for everyone at Acta Marine,” said Rob Boer, CEO of Acta Marine.
“Although Acta Hercules is already successfully supporting our client Vestas, this christening provides an opportunity to recognise the many people, partners and organisations who contributed to her development, construction and delivery. Acta Hercules strengthens our ability to support clients in the rapidly growing offshore wind market”.
Delivered earlier this year as the second vessel in Acta Marine’s four-vessel newbuild CSOV programme, Acta Hercules is currently deployed under a long-term charter supporting offshore wind operations for Vestas.
Following the deliveries of Acta Pegasus, Acta Hercules and most recently Acta Gemini, the company expects to take delivery of the fourth and final vessel in the series, Acta Aquarius, later this year.
Upon delivery of Acta Aquarius, Acta Marine’s fleet will comprise seven dedicated Walk-to-Work and Construction Service Operation Vessels, further strengthening the company’s position as a leading provider of offshore support solutions for the offshore wind industry.
Together, these vessels form the foundation of a modern, scalable and increasingly sustainable fleet, enabling Acta Marine to support clients throughout the full lifecycle of offshore energy projects across Europe.
