Zenitel’s integrated communication systems onboard support sustainability goals and enhance real-time coordination in demanding offshore environments.

Designing a Methanol-Powered Offshore Vessel

NSK Ship Design has developed a unique concept for the new vessel, featuring a hybrid engine and equipment on board such as a 150-ton AHC crane with 3D topside lifting capabilities and dual integrated ROV systems. The CSV is designed to perform a wide range of tasks — from light construction work, inspection, and repair to support operations. The new vessel is equipped with a dual-fuel diesel/methanol electric drive and an optimized battery package, significantly reducing its carbon footprint and enabling an approximately 75% reduction in CO₂ emissions.

The vessel is under construction at Sefine Shipyard in Turkey, a leading shipbuilder known for its strategic location, advanced capabilities, and strong track record in delivering vessels to Norway and other key maritime nations. Over the past decade, Sefine has established itself as a trusted partner for complex vessel builds, particularly in the offshore, utility, and passenger segments. With a growing reputation for quality, flexibility, and timely delivery, the yard has become a preferred choice for European shipowners seeking modern, environmentally aligned shipbuilding solutions.

United for a Sustainable Future

Eidesvik Offshore and Agalas have joined forces to deliver a transformative solution: a methanol-powered offshore vessel designed for subsea and offshore wind operations. This strategic partnership combines Eidesvik’s decades-long expertise in pioneering low-emission technologies with Agalas’ agility, ambitions, and commitment to sustainable goals. Together, they are building a vessel that sets a new benchmark for environmental performance in its class.

The newbuild vessel will be owned by Eidesvik Agalas AS, a newly established entity where Eidesvik holds a majority stake of 50.1%, while Agalas owns the remaining shares. With options for four additional vessels, the partnership reflects long-term ambitions and confidence in the market’s direction.

This collaboration is not only a leap toward decarbonizing offshore operations but also a catalyst for job creation in the Northern Norway region. By uniting innovation, regional strength, and shared vision, Eidesvik and Agalas are actively shaping a more sustainable maritime future.

Meeting the Growing Demands of the Offshore Wind Industry

Eidesvik and Agalas recognize that the timing for their new methanol-powered offshore vessel is optimal, as demand in the subsea market is approaching a point where demand is outpacing supply. With substantial growth forecasted for offshore wind throughout this decade, the need for efficient, future-ready support vessels has never been greater.

With governments aiming to ramp up Europe’s offshore wind capacity from 30 GW to 120 GW by 2030—and ultimately 300 GW by 2050—support vessels must evolve accordingly. More than 80% of this capacity is in the North Sea, reinforcing Europe’s role as a global offshore wind leader.

As offshore wind farms expand, the demand for low-emission, flexible support vessels continues to grow. While turbines produce green power, service and maintenance tasks, as well as crew transfers, can still contribute to the overall carbon footprint. Utilizing eco-friendly vessels—especially those powered by alternative fuels or hybrid systems—will be essential in minimizing emissions and other pollutants.

Integrated Communications for Offshore Reliability

To support seamless operations at sea, Zenitel is providing a comprehensive suite of integrated communication systems for the new methanol-powered offshore vessel. The package includes a terrestrial antenna system, LAN infrastructure, sound reception system, SPA-V2 PAGA system, ICX-500 intercom, IP DECT system, and an IP CCTV system.

These technologies are critical for maintaining situational awareness, safety, and coordination in demanding offshore environments. Tailored specifically for offshore wind and subsea operations, Zenitel’s integrated solutions ensure uninterrupted communication and fast response times—key to both crew safety and mission success. By reducing delays, enhancing operational flow, and supporting compliance with maritime safety standards, they contribute directly to the vessel’s efficiency and reliability in low-emission, high-performance operations.
