Finnsnes Dykk & Anleggservice AS (FDA) has awarded Zamakona Yards Bilbao a contract for the construction of a new Anchor Handling Subsea Vessel (AWH), with Sirius Design & Integration selected as design and system integration partner.

The vessel will be built in Spain and delivered under Norwegian flag, classed by DNV, with scheduled delivery in Q2 2028.

The newbuild is based on Sirius’ AWH design and is tailored for multi-purpose operations, including anchor handling, offshore fish farming, pipelaying, subsea work, ROV operations, and a flexible deck for special purpose operations. The vessel will be equipped with hybrid diesel-electric propulsion and battery energy storage, enabling reduced fuel consumption and emissions, and will be prepared for operation on HVO fuel.

At approximately 50 metres in length and 14 metres beam, the vessel is designed to deliver a bollard pull of minimum 50 tonnes and a service speed of around 12 knots.

The deck layout includes capacity for cable operations with a 250-ton turntable, while a dedicated ROV hangar with launch and recovery system supports subsea operations. The vessel will also be fitted with three cranes, including heavy-lift capability, and will feature dynamic positioning for precise offshore work.

The project has been developed in close cooperation between the shipowner, shipyard, designer and suppliers, with a focus on operational flexibility and efficiency.

Keneth Larsen, FDA, says the vessel represents an important addition to the company’s fleet:
"We have had a strong cooperation with both Sirius and Zamakona in the development phase, and we look forward to taking delivery of a modern and capable vessel tailored to our operations."

Luis Magro, Managing Director at Zamakona Yards, says the contract strengthens the yard’s position in the Service & Subsea segment:
"We are pleased to secure this project with FDA and to collaborate with Sirius. Together, we will deliver a high-quality vessel."

Christian Søvik, EVP Sales & Marketing at Sirius Design & Integration, says the contract confirms the company’s position in advanced vessel design and innovative hybrid solutions:
"We are proud to be selected by FDA and look forward to continuing the strong cooperation with both the owner and the yard."

The project is expected to generate activity for a number of equipment suppliers and further strengthen collaboration across the maritime value chain.

The vessel will be built at Stadyard in Raudeberg and is scheduled for delivery in summer 2028.

The new vessel will have a length of 50.3 metres (LOA) and a freezer hold with a capacity of 630 m³. The vessel is designed for efficient operations and high raw material quality in fisheries in the North Atlantic.

“We are proud to be selected by P/F Regn and the Framherji Group for this project. Together with the shipping company, Stadyard and the project’s suppliers, we look forward to developing a modern and efficient longline vessel adapted to operations in the North Atlantic,” says Håvard Sætre, CEO of Sirius Design & Integration AS.

The design has been developed in close cooperation between the shipping company, the yard and suppliers, with particular focus on efficient catch handling, good onboard logistics and robust solutions for demanding operations.

A future-oriented longline vessel

“We have had very good cooperation with both the shipping company and the yard in the development of the design. The goal has been to develop a future-oriented longline vessel that combines efficient catch handling, energy-efficient operations and good solutions for the crew on board,” says Agnar Juvik, Chief Designer at Sirius Design & Integration AS.

At Stadyard, the project is highlighted as an important newbuild for the yard and the supplier industry.

“We are very pleased with the trust P/F Regn and the Framherji Group have shown us by placing this project with Stadyard. This is an exciting and forward-looking project that will provide activity for the yard and our partners for a long time to come,” says Agnar Lyng, CEO of Stadyard.

For the shipping company, the contract marks an important step in the continued development of the fleet.

“We have good experience from building vessels at Norwegian yards and look forward to the cooperation with Stadyard, Sirius and the other parties involved in the project. Our goal is to obtain a modern and efficient vessel that will facilitate good operations for many years to come,” says Anfinn Olsen of P/F Regn.

A CSV is designed to support construction, installation, and maintenance activities at sea, particularly within the offshore wind, oil and gas, and subsea sectors.

This article explains what a Construction Support Vessel is, what CSV stands for, and why these vessels are essential for offshore operations.

What Does CSV Stand For?

CSV stands for Construction Support Vessel.

The term is used to describe a category of offshore vessels built to assist with a wide range of marine construction tasks. Unlike traditional supply or transport vessels, a CSV is purpose-built for technical operations that require precision, stability, and advanced onboard systems.

CSVs are commonly used during the installation of offshore infrastructure such as wind turbines, subsea cables, pipelines, platforms, and foundations.

What Is a Construction Support Vessel Used For?

A Construction Support Vessel functions as a floating work platform. It supports offshore construction teams by providing equipment, workspace, accommodation, and operational capability directly at the project site.

Typical tasks include:

• Subsea construction and inspection
• Offshore wind turbine installation and servicing
• Cable laying and protection
• Maintenance, repair, and modification (IRM) work
• Support for diving and remotely operated vehicle (ROV) operations

Because offshore conditions are often harsh and unpredictable, CSVs are engineered to maintain precise positioning and operational stability even in challenging weather.

Key Features of a Construction Support Vessel

While designs vary depending on the vessel’s intended use, most Construction Support Vessels share several core characteristics.

A CSV is usually equipped with dynamic positioning (DP) systems, allowing it to hold position accurately without anchoring. This is essential when working close to subsea assets or fixed installations. Many vessels also feature large deck areas to accommodate heavy machinery, containers, and construction materials.

Other common features include onboard cranes, moonpools for subsea deployment, workshops, and advanced control rooms. Accommodation facilities are often designed to house technicians, engineers, and offshore crew for extended periods.

Industries That Rely on CSVs

Construction Support Vessels are a vital asset across multiple offshore industries. In offshore wind, they are used throughout the project lifecycle. From foundation installation to long-term maintenance. In the oil and gas sector, CSVs support subsea tie-ins, platform upgrades, and decommissioning activities.

As renewable energy expands globally, CSVs are increasingly adapted to meet the needs of offshore wind farms, floating energy solutions, and hybrid energy projects.

Why Construction Support Vessels Matter

In an offshore environment where precision and reliability are critical, a well-equipped CSV can be the difference between delays and successful execution.

A Construction Support Vessel (CSV) is a specialized offshore vessel designed to support construction, installation, and maintenance work at sea. Equipped with advanced positioning systems, heavy-duty equipment, and onboard facilities, CSVs are essential to offshore wind, oil and gas, and subsea operations. As offshore projects continue to grow in scale and complexity, Construction Support Vessels will remain a key part of the global maritime and energy industries.
