New offshore launch and retrieval system
Deep Down Inc., Channelview, Tex., has delivered a launch and retrieval system (LARS) that the firm believes to be the deepest class rated unit of its kind in the world.
The 4,000 m rated LARS is specially designed for subsea load handling, lifting and tensioning, and launch and retrieval of specialized underwater equipmentincluding remotely operated vehicles (ROVs)in ultradeep and harsh subsea environments. Special functions include autovariable speed control (load dependent), wire spooling and guide systems, grooved drums, emergency release capabilities, gravity lowering, emergency hoisting abilities, and a water-cooled drum to reduce heat on the umbilical.
The safe working load of the LARS is 28 tonnes, and the system is capable of delivering payloads at speeds of up to 76 m/min. It also features a specially designed wraparound level wind sensor system that allows for more sensitive yet smoother operation in rugged, high-load, ultradeepwater applications.
The 4,000 m LARS was sold to Perry Slingsby Systems Inc., Jupiter, Fla., for integration with Perry’s new 4,000 m rated ROV.
Perry sold the integrated unit to Paris-based Veolia ES Special Services Inc., which has placed the system on Veolia’s newly built DSV MT-6016 Swordfish marine vessel. The new ship is custom designed to allow Veolia to take on more complex subsea construction and dive-support projects. The Swordfish also has a 3,000 m rated LARS leased to Veolia with a Perry ROV.
A second 4,000 m rated LARS is expected to be delivered to Perry as soon as factory acceptance testing has been completed. The second LARS will also be sold to Veolia with a Perry ROV.
