SOV & CSOV

A Service Operations Vessel (SOV) or Commissioning SOV (CSOV) is a purpose-built offshore support vessel designed to provide hotel functions and stepless walk-to-work (W2W) access for technicians, commissioning and maintenance materials and equipment. Designed to support long-term operations at offshore wind farms and oil & gas structures, Damen’s SOV and CSOV range ensures reliable, efficient workflows and comfortable living conditions – even in the most demanding environments.

Hybrid Propulsion as Standard
Every Damen service operation vessel comes with a hybrid diesel-electric propulsion system with battery support. This significantly reduces fuel consumption, lowers emissions and supports flexible operations across a wide range of conditions.

Efficient Thruster Layout
An optimised thruster arrangement, featuring the Damen DPX-DRIVE with four independent azimuth thrusters, maximises propulsion efficiency. It enables precise manoeuvring, reduces vessel movement in DP mode and lowers fuel use and emissions.

Future-Ready Fuel Systems
Our in-house research team is actively developing solutions for low- and zero-carbon fuels, supporting the industry’s transition away from fossil energy. Our SOVs are designed to accommodate alternative fuel technologies and comply with future regulations. All our vessels are delivered methanol-ready as standard, with the flexibility to integrate other available alternative fuel systems.

Remote Performance Monitoring
With Damen Triton, our digital remote monitoring system, operators gain valuable insights into fuel consumption and equipment performance – improving uptime, enabling more accurate maintenance scheduling and fuel consumption optimisation.

Stability first
A stable platform is the foundation of crew wellbeing. Our hull forms are optimised for the short-crested waves typical of offshore wind locations, minimising motion and maximising comfort and safety during operations.

Low noise and vibration
Damen SOVs are built to reduce onboard noise and vibration levels, providing a quieter, calmer environment that supports concentration during work and proper rest when off duty.

Thoughtful accommodation design
All accommodation is positioned lower in the vessel compared to traditional offshore designs, where motion is reduced. Combined with high-quality outfitting, it offers a welcoming and comfortable onboard experience - a true ‘home away from home’.

Designed for Stepless Access
Every Damen service operations vessel is engineered around safe personnel transfer. Integrated walk-to-work systems enable stable gangway operations, reducing transfer risks and downtime.

Real-Time Motion Prediction
Onboard software analyses conditions and predicts extreme ship movements, helping crews plan safe transfers more effectively and avoid unsafe moments.

Informed Decision-Making
From weather predictions to vessel behaviour analytics, crews have access to real-time operational data to support safer and smarter planning.

Optimised Hull Form
Every Damen SOV is designed for minimal motion and maximum uptime. This results in a stable working platform that increases transfer safety and offshore availability.

Logical Internal Layout
Drawing on decades of design experience, we ensure that each level of the vessel – from cargo deck to control room – is practical, safe and intuitive for crew use.

Custom-Fit Mission Profiles
Need cranes, extra storage or specialist tools? Our modular approach allows for bespoke layouts that support every mission requirement – from commissioning to maintenance.

Custom-Fit Mission Equipment
Damen offers full flexibility when it comes to mission equipment. Whether you need cranes, rescue systems or specialised workstations, we integrate your preferred equipment seamlessly into the design.

Walk-to-Work Systems
Select the walk-to-work system that best suits your operations. We ensure full compatibility and smooth integration, whatever your choice.

Crew and Cargo Transfer
Choose the CTV or crew transfer method that works for your project. Damen’s designs support flexible solutions to meet any personnel transfer need.

All Damen SOVs can be configured for 100% electric operation. The SOV 7017 E - previously launched as the world’s largest fully electric offshore service vessel - demonstrates this capability. With offshore charging and zero-emission performance, it marks a major step forward in sustainable windfarm support.

Key Features of the SOV 7017 E:

• 70 x 17 metre footprint

• Fully electric propulsion

• Offshore charging system

• Emission-free operation during windfarm maintenance

• LFP battery for reduced reliance on sensitive raw materials like cobalt

“With the SOV 7017 E, we’re not just responding to new regulations – we’re leading the way to a cleaner future,” says [Damen spokesperson or project lead].

Tailored to Your Mission
Each Damen vessel is custom-built around your operational and sustainability goals. We combine proven hull forms with modular layouts and open system integration.

Built on Partnership
From initial consultation through to commissioning and global support, Damen is your offshore energy partner – helping you operate smarter, safer and more sustainably.

Total Lifecycle Support
With Damen Services and our worldwide Service Hubs, you receive support where and when you need it. From spare parts to digital diagnostics, your vessel is always in safe hands.
