Allseas’ purpose-built cargo barges Iron Lady, Braveheart and Bumblebee support our record-breaking platform removal and installation operations, delivering efficient topsides and jackets loading and transfer solutions to and from disposal yards.

Offshore pipelay

Iron Lady  

Purpose-built to fit precisely within Pioneering Spirit’s bow slot, Iron Lady facilitates smooth topsides transfers when quayside water depth is insufficient. Her robust ballast system and flat deck with SMPTs ensure efficient on-deck load skidding, while load capacity zones enable extreme loads for large-scale projects.

Braveheart 

Expected in late 2025, Braveheart will mirror Iron Lady’s capabilities with enhanced features, including a full electric ballast system that provides DNV Class 1 compliant load transfer and tidal compensation. Braveheart’s shore power connection and integrated water treatment system underscore our commitment to improved efficiency and environmental consideration.
