| titleOfInvention | Backup heave compensation system and lifting arrangement for a floating drilling vessel |
| abstract | Backup heave compensation system and an associated lifting arrangement (104) for a floating drilling vessel comprising a rig structure (105) with a primary heave compensation system, said backup heave compensation system comprising: - a vertically extendable and retractable lifting arrangement (104); - a hydraulic system (110, 113, 204, 222, 225, 703) operatively connected to said lifting arrangement (104); and - a control system (208) operatively connected to said lifting arrangement (104) and hydraulic system (110, 113, 204, 222, 225, 703) for selective control and operation thereof; said lifting arrangement (104) comprising: - a rigid frame structure (201) comprised of: at least two vertically extending cylinders (203); a first transverse element (205) connecting first end portions of said cylinders (203); and a second transverse element (206) connecting second end portions of said cylinders (203); and - a portal structure (202) comprised of: at least two vertically extending piston rods (217) having first end portions provided each with a piston (218); and a transverse portal element (214) connecting second end portions of said piston rods (217); - wherein each piston (218) is movable within a corresponding cylinder (203). |
