Some old vessels, especially those that are very well known, are preserved and sent to museums or even themselves turned into museums. There’s one last option for old ships: preserve them as an artifact, museum, restaurant, hotel, or other purpose. It’s also more environmentally friendly due to the reuse of the current structure and a lot of parts instead of producing all new steel and components. Converting a ship can be a faster and more economical process than building a brand new vessel from scratch. Ulstein also converted the Normand Cutter and Normand Clipper from cable laying vessels to pipelaying and construction vessels with additional cabins, ROV hangar and control room, dynamic positioning upgrades, crane relocation and upgrade, deck reinforcement, and widening the vessel by 3.6 meters, according to Ulstein. The project involved installing a hybrid power system, methanol tanks, rescue zones, and fast rescue boats. They converted two of Esvagt’s vessels, Esvagt Leah and Esvagt Heidi, into Emergency Response and Rescue Vessels (ERRVs). Companies like Ulstein can convert ships like a platform supply vessel (PSV) into a subsea construction or offshore wind service vessel. If upgrading a ship won’t cut it, there’s always the option of converting it into another type of vessel that is in higher demand. Sinking and even burning vessels used to be a much more common practice with wooden ships, but the steel in modern vessels can be reused or melted down to make new steel. More recently, “any recycling yards have improved conditions to meet IMO’s guidelines with impervious floors, drainage systems, cranes, and worker training for each specific vessel.” ( What is ship recycling?) Recycling rates at these yards can be as high as 98%, with the alternative to recycling being sinking a vessel to create an artificial reef or storage in a ship graveyard. Conditions vary widely depending on the location and ship yard, with some operating with no safety or environmental guidelines, while others have stepped up waste processing and worker care. The process involves running ships aground and taking them apart with torches, wrecking balls, cranes, and any methods available. Dismantling ships is dangerous and labor intensive work that is mostly done in Asia, although can be done anywhere. The first option is recycling, also known as ship breaking.
