Qingdao, China – October 2025 — Dutch heavy marine transport specialist Boskalis has once again demonstrated the capabilities of its record-setting semi-submersible vessel, BOKA Vanguard, by loading a massive floating dry dock for Grand Bahama Shipyard onto its deck.

The operation took place in Qingdao, China, where Boskalis’ project team successfully loaded the 335-meter-long floating dock, named “East End,” onto the world’s largest heavy transport vessel. The cargo extends 44 meters beyond the stern and 17.5 meters beyond the bow, underscoring the extraordinary scale of the mission.

The BOKA Vanguard, already renowned for its groundbreaking design, underwent a 10.3-meter widening in 2024 to accommodate even larger and heavier transports. With a current beam of 80 meters, the vessel can now handle some of the world’s most challenging offshore and shipyard cargoes. The “East End” floating dock, measuring 75 meters wide, fits seamlessly between the widened casings of the vessel — a testament to Boskalis’ precision engineering and operational planning.

Upon completion of loading, the BOKA Vanguard departed for the Bahamas, marking another milestone in heavy marine logistics. Boskalis expressed gratitude to Grand Bahama Shipyard and Seabridge Marine for their partnership and trust, wishing the crew a safe and successful voyage.

This latest project reinforces Boskalis’ reputation for redefining the boundaries of marine heavy transport, leveraging engineering excellence and innovation to serve shipyards and offshore industries worldwide.
