A coupling apparatus and a method are for connecting two drill-pipe sections in a string of drill-pipe sections joined together by tool joints. The coupling apparatus comprises: a first pipe with a first end portion and a second end portion, the first end portion being provided with a tool joint for connection to a drill-pipe section; a second pipe with a first end portion and a second end portion, the first end portion being provided with a tool joint for connection to a drill-pipe section.

A drainage device is for a tubular, telescopic pipe-landing unit having a through pipe bore partially formed of a center pipe extending from an upper end portion of an outer pipe-landing section and with a free end in through an upper end portion of an inner pipe-landing section, which is axially movable in the outer pipe-landing section. The center pipe has a fluid-communication opening arranged for pressure equalization between the pipe bore and an annulus between the center pipe and the outer pipe-landing section. The annulus has a drain passage arranged to be opened by the axial movement of the inner pipe-landing section into the outer pipe-landing section away from an extended, operative position, in which an abutment portion on the upper end portion of the inner pipe-landing section is resting sealingly against a seat portion on a lower end portion of the outer pipe-landing section.

A backup heave compensation system and an associated lifting arrangement are for a floating drilling vessel comprising a rig structure with a primary heave compensation system. The backup heave compensation system comprises: a vertically extendable and retractable lifting arrangement; a hydraulic system operatively connected to said lifting arrangement; and a control system operatively connected to said lifting arrangement and hydraulic system for selective control and operation thereof. The lifting arrangement comprises: a rigid frame structure comprised of: at least two vertically extending cylinders; a first transverse element connecting first end portions of said cylinders; and a second transverse element connecting second end portions of said cylinders; and a portal structure comprised of: at least two vertically extending piston rods having first end portions provided each with a piston; and a transverse portal element connecting second end portions of said piston rods. Each piston is movable within a corresponding cylinder.
