Rolls-Royce has secured a contract by the Brazilian ship owning company CBO to equip an existing offshore platform supply vessel (PSV) with a new patented dual draglink (DDC) subsea crane.
This will be the first installation of a subsea crane designed to be able to use either fibre or steel wire rope, the company said.
The hybrid DDC subsea crane will be installed on the vessel CBO Manoella, which is currently being retrofitted from PSV into a ROV support vessel (RSV).
Marcelo Martins, CBO, technical director said: “This is one of two vessels CBO is now retrofitting from PSVs to RSVs, and we are very satisfied about the flexibility of the crane from Rolls-Royce. A hybrid solution, with use of either fibre or wire, makes the vessel better prepared to take on a larger variety of future subsea tasks.”
The crane to be installed on CBO Manoella is a hybrid dual draglink crane with a lifting capacity of up to 50 tonnes and an operating depth of up to 3,000 meters. It will be equipped with wire rope when it embarks on its first subsea assignment off the coast of Brazil.
CBO Manoella has a Rolls-Royce UT 715 L design and first went into service in 2009. It was the number two in a series of nine UT 715 L-designs ordered by CBO.
Gary Nutter, Rolls-Royce, director, Products – Marine said: “We are very happy to be able to continue our close cooperation with CBO by retrofitting one of our previous designs. This project is a great example of how offshore ship owners are adapting to a new reality with the use of new technology.”
The delivery from Rolls-Royce will take place in Q3 this year.
