Upgrading tonnage to a new life

A shipowner's decision on upgrading a vessel into an updated, ready-classed version, or converting it to a new segment can lead to increased interest and a firm contract. We can convert any vessel into a new type, with our offshore-tough ULSTEIN know-how at the basis.

As maritime professionals, we have teams of shipbuilding and ship design experts who can upgrade any vessel or convert it for a new segment – to secure the shipowner a ‘new’ vessel with a short delivery time.

Our ship yard delivers high quality ship repair and conversions. Close collaboration between naval architects and the project team secure cost effectiveness, quick responses and complete conversions. Read more.

Upgrades and modernisation
One of our latest upgrading assignments has been the renovations of the 'Ocean Adventurer' expedition cruise vessel in 2017 (photo below, before the upgrade). The refurbishment has lead to a general modernisation throughout the vessel, and significant technical upgrades have also been carried out, securing a vessel with increased fuel efficiency and, subsequently, a minimized carbon footprint.



Conversion to other vessel types
We can transform an offshore vessel, such as a PSV, into another offshore type vessel, typically a multipurpose support vessel, light subsea construction vessel or offshore wind service vessel, or into a non-offshore vessel like a fish carrier, yacht or expedition cruise vessel. 

The example vessel in the top photo is the 'EDT Jane', supporting underwater works near the AMOCO P15-F platform west of Scheweningen. The vessel was originally built as a platform supply vessel of the PX105 design, and later converted to a multipurpose support vessel.

On-time deliveries
ULSTEIN is a group of maritime oriented companies. As offshore experts, we know how the sea forces can beat and hammer a vessel. As ship designers, we possess expert teams for all parts of a vessel, including areas such as hull strength, hydrodynamics and machinery. Our own yard, the Ulstein Verft, is a long-term partner with expertise in building, converting and repairing vessels. Our dock hall secures top facilities for the safe and controlled repair and upgrade of any vessel. 

We develop basic and detail conversion designs, based on our own ULSTEIN designs or external designs. Close collaboration between our naval architects and the project team secures cost effectiveness, quick responses and complete conversions delivered on time.

References through 100 years
ULSTEIN has built ships for a century, and has developed ship designs since the early 1970s. Our references include offshore vessels, passenger vessels, ro-ro vessels, fishing vessels and more. We can also be your partner in project management, system integration and on-board solutions. We design to secure safe and reliable operations with low emissions, resulting in cutting-edge solutions and reduced life cycle costs. This contribute to high productivity and an improved return on investment. 

The photo series below shows the conversion of the 'Normand Cutter' in 2004. This vessel, and her sister vessel, 'Normand Clipper', were built as cable laying vessels at Ulstein Verft. As the market for cable laying entered into a downturn, the vessels were converted into pipelaying/construction vessels. The major conversion (read more) can be compared to the newbuild of a platform supply vessel, and was carried out in five months.
