Hey all,
I'm a Toolpusher on a dual derrick drillship that is capable of off-line stand building activities. The ship is not full dual activity, which is what I would ultimately would like to work on.
I helped doing the commissioning of the equipment on here when it was in South Korea shipyard. She's a good rig, and there is plenty of room on the decks and on the drill floor. The derrick is rated to 2 million pounds, and we have a 1 million pound crown mounted compensator. Running BOPS is a breeze compared to conventional rigs. When we ran the BOP last time in 2100 meters of water, the string weight was around 1.6 million.
It truly is amazing that you can have that much weight just literally at your finger tips. It's all joystick controls. If you were to have that kind of weight on a conventional rig, the old pooper valve would be working overtime, and you would have the AD helping to lean on the brake handle!
Although joystick control is good, you sort of loose the feel of the weight and magnitude of what could go wrong. The drillers' cabin is sound proofed, the drawworks drum is disc brake, so there is literally no noise.
I would recommend for anyone that has a chance to work on one of these rigs. These are the rigs of the future, and in time, the brake handle will be a thing of the past.
