Understanding Heavy Lift Vessels (HLVs): Design, Operation And Types

Ship_spotting_Greece on Instagram: "A semi-submersible ship is a specialized heavy-lift vessel designed to transport extremely large and heavy structures by partially sinking its deck. By ballasting down, the ship submerges its cargo deck so floating loads—such as oil rigs, offshore platforms, yachts, or damaged ships—can be positioned over it; the vessel then deballasts, rising up and lifting the cargo clear of the water. This design gives semi-submersibles exceptional stability in rough seas a

Sailor’s Compass 🧭 on Instagram: "This isn’t a ship in trouble — it’s a special type of vessel called a semi-submersible heavy-lift ship. It fills its ballast tanks with seawater to lower the deck underwater, allowing large structures to float above it for loading. Once secured, the ship pumps out the water and lifts the cargo safely. A smart engineering design that makes transporting massive offshore structures possible. #maritime #shipping #seafarers #merchantnavy #oceanengineering"
