Antaeus Ultralift has also delivered specialized engineering designs across a range of offshore renewable energy applications. These include:

• Structural design of steel support extensions for offshore crane booms on large installation vessels.
• Engineering, fabrication, and testing of frames for porpoise detection sensors deployed ahead of wind farm construction; the subsea systems included acoustic sensors and recording units, positioned on the seabed and later recovered using acoustic release buoys after a one-year monitoring period.
• Sea fastening cradles for transporting tower sections in conventional cargo vessels.
• Deck-mounted sea fastening frames for securing nacelles, transition piece sections, and blade racks during transit.
• Design of offshore metocean masts across several projects.
