For me, the most impressive moves the semi-submersibles make are the oil rigs... out of the water they are so tall & wide with such a high centre of gravity that it looks like a truck carrying a 6-storey office building on the trailer! The forces that all that steel resists are truly mind-boggling.

The other application is to substitute for dynamic launches of ships. HMS Glasgow Type 26 Anti Submarine frigate was recently skidded onto a barge at Govan on the Clyde, towed to Loch Long, floated off and taken back to Scotstoun for filling out. Dynamic launches are much more dramatic but also stressful to the hull.

It's worth mentioning that the load is welded to the heavy lifter's deck after being raised and is cut free before refloating. Needless to say, with this kind of load the risk of it coming lose while underway needs to be as close to zero as humanly possible! First time I saw anything on a heavy lifter upclose was HMS _Nottingham_ on the MV _Swan_ in Garden Island, Sydney back in 2002 after she had that all too close encounter with Wolf Rock off Norfolk Island. The Type 42 destroyers weren't big ships even compared to their contemporaries (very much a bean counter's design), but even she seemed oddly colossal with her whole hull out of the water compared to when I'd seen T42s alongside elsewhere.

i have worked on one of the two semi's from Big Lift. while it was in port. they were actually working on two at the same time as they. the two sister ships would have to be work in tandem. it was even for them a new thing. they only needed to be able to lift the actual platform out of the water and (the reason as to be in tandem side by side) sail so that they could sail above the tower part. really impressive

You can actually trace this back to a similar design the US Navy began using in the early 20th Century. Floating Drydock USS Dewey YFD-1 was launched in 1905. The vessels developed based on this design provided essential forward repair support for the US Navy during the island hopping campaign of the Second World War. Once an island was secured, a floating dry dock and supply ships could be moved into a suitible cove or existing harbor instantly providing the ability to repair, rearm, or refit even capital ships (Battleships and Carriers). While the number available was not high, it did allow for quick emergency repairs to help a ship survive the journey from the front lines to the US West Coast.

I once was in the port of Rotterdam for a tour of the newly reclaimed land. The harbour on it was already kind of in operation. At the time the pioneering spirit, which used to be one of the biggest semi submersibles and the at the time biggest cargo ship, the HMM algeciras, were both in port. The pioneering spirit was submersed and carrying some kind of platform but there were problems on board accoarding to the tourguide so it wasn't going to actually move for a few days.

Excellent video once more, thanks. Pretty clever to use a semi-submersible vessel to transport a semi-submersible rig, isn't it? It is massively impressive: the DOckwise Vanguard can lift up to 110.000 tonnes. If you compare that to heavy lifting vessels, like the Heerema Sleipnir (20.000 tonnes in tandem lift) or the Allseas Pioneering Spirit (over 48.000 tonnes and the largest vessel in the world - also kind of semi-submersible), it is a huge difference.

Dockwise/Boskalis has a solution for the buoyancy casings. The MS3 has/had a 300mt counterweight at the stern. She was able to submerge with the casings placed in their storage position. Lowering the counterweight to the bottom and “winching” the vessel down gives sufficient longitudinal stability to operate without the casings.

@karstendoerr5378 Жыл бұрын

This idea is not new. The term LASH (Lighter Aboard Ship) refers to a system in which loaded lighters are transported on ocean-going vessels. The carrier ships are called LASH carriers, barge carriers, kangaroo ships, lighter transport ships, or lighter mother ships. The only difference is that they were not used to transport ships, but take on vessels designated as lighters, preherms, barges or barges without their own propulsion in the form of floating standardized cargo containers. At the port of destination, the carrier ship separates from these vessels again. There, they are moved in the port waters, on canals and rivers as inland waterway vessels in pushed convoys. Such vessels first appeared in 1969.
