That OSV designs get converted to OWF operation has been common, but here is a FCS that is going the other way:

Another type of vessel tat can be used for both offshore wind and oil & gas operations:

World’s largest heavylift jackup begins operations - Splash247

The Obana was recently completed at the Damen Shipyard in Rotterdam. It is a six-legged jackup comprised of 85% recycled steel and was engineered by merging two repurposed former drilling rigs, the Brage and Gabrus, with a newly built mid-section constructed in Dubai.

Both rigs were built at Keppel FELS, Singapore as Galaxy II(1998) & III (1999) respectively:

If the barge has thrusters to keep station on DP, shouldn’t it be classed as a ship?

Sounds like what’s called a “self propelled barge”. I’m not sure how the USCG will regulate it.

It is becoming normal to build cross service vessels:

Marco Polo Marine to build cross-sector CSOV at Indonesian yard

The company is working with Norway-based Salt Ship Design on the new vessel, which it has dubbed the ‘CSOV Plus.’ Salt Ship Design has signed a contract with Marco Polo Marine’s Taiwan-based subsidiary PKR Offshore for the design, which will be built at Marco Polo Shipyard Pte Ltd in Batam Indonesia.

The CSOV Plus combines the use of a walk-to-work gangway with excellent stationkeeping and manoeuvrability, and will enable safe personnel transfer in significant wave heights up to 3.0 m.

Another Cable layer project is launched by the Italian national electricity grid management company https://www.terna.it/en:

Terna’s project for the construction of its first cable-laying vessel is getting underway.

The company, which expects to take delivery of it in early 2030, has launched a tender to provide technical support services
With the launch of a European tender for engineering, technical support and supervision activities, Terna’s project to equip itself with its first cable-laying vessel, for which it had already launched a market consultation last year, is getting underway.

More specifically, the tender launched today includes “specialized technical support” services that will accompany Terna “throughout the entire procurement, construction, and commissioning process” of the vessel. The winning bidder will be responsible for drafting the tender documentation for the supply of the vessel, providing technical assistance throughout the tender process, technical supervision of the detailed design and construction activities, and finally, support during the warranty period.

Jan De Nul invests in rock installation newbuild - Splash247

Although the shipyard of choice and delivery schedule have yet to be disclosed, the newbuilding will join Jan De Nul’s expanding offshore fleet, which also includes two extra-large cable layers under construction, the Fleeming Jenkin and the William Thomson. Each will carry up to 28,000 tonnes of cable, designed for long-distance interconnectors linking power grids across continents.

The George W. Goethals is named after the American engineer who oversaw the construction of the Panama Canal, a project in which Jan De Nul was involved during the 2009–2016 expansion works.
