Build underway for methanol hybrid CSOVs

Batteries in Maritime	Autonomy at Sea	Alternative Fuels	Tugs, Towing & Salvage

Examining the growing role of batteries in maritime, questioning their green credentials while exploring industry insights, operator experiences and lessons learned from early electric vessel adoption worldwide.	Highlighting the innovators advancing subsea and maritime technology, from autonomous underwater swarms to cloud-connected assets and data-driven predictive models, reshaping how real-time conditions at sea are understood globally today.	Exploring one of the workboat sector’s dilemmas today: which emerging fuels hold the most promise in terms of cost, availability, practicality and performance? Or should we simply clean up the Black Gold?	Looking at how tugs, towing and salvage vessels are adapting to stricter regulations; contemplating new propulsion technologies and alternative fuels; and changing design strategies for one of maritime’s most demanding sectors.

The steel-cutting ceremony for the first of two next-generation methanol hybrid construction service operating vessels has been held on 18 January 2023 at Tersan Shipyard in Turkey.

The new 89 metre CSOV will join the Acta Marine fleet in the second quarter of 2024 together with the second newbuild which will follow three months later.

The bespoke SX216 design for the methanol MDO/HVO DP2 vessels has been developed in collaboration with Ulstein Design & Solutions and are the first contracted to use Ulstein’s TWIN X-STERN design.

The combination of two sterns and main propellors at each end is said to reduce energy consumption and increase comfort as well as improving manoeuvrability and ability to stay in position

The TWIN X-STERN was recently nominated for the Offshore Support Journal Innovation of the Year Award and the Acta Marine CSOV project is nominated for the Offshore Renewables Award.

The vessels can accommodate up to 135 crew and come equipped with an SMST-provided motion-compensated crane and a motion-compensated gangway for personnel transfer in wave heights up to 3 metres. In addition to the methanol MDO/HVO engines the CSOVs also have a battery power storage system.
