Transition Piece Lifting Tool for SAL

Installing transition pieces offshore requires absolute control. Loads are heavy, geometries are complex, and environmental conditions leave little room for uncertainty.

For SAL, Tillen developed a fully custom Transition Piece Lifting Tool that ensures controlled handling during offshore wind installation. The tool was engineered to match the operational sequence, vessel configuration, and site-specific conditions.

From initial concept to proof load testing, Tillen delivered a complete fit-for-purpose solution that supports predictable, safe, and efficient offshore operations.
