Abstract
A marine drilling riser protection system including a plurality of protection modules adapted for fitment at spaced intervals along the length of a riser, and a plurality of cover parts, wherein each cover part is adapted to be fitted at one end of the cover part to a first protection module, and at an opposite end of the cover part to a second protection module.
Claims17
A marine drilling riser protection system including:
- a plurality of protection modules adapted for fitment at spaced intervals along the length of a riser, wherein each of the plurality of protection modules has two recesses extending around an outer surface of the protection module with a first recess of the two recesses located near one end of the protection module and a second of the two recesses located near another end of the protection module;
- and
- a plurality of cover parts, wherein each of the plurality of cover parts has two recesses extending around an outer surface of the cover part with a first recess of the two recesses located near one end of the cover part and a second of the two recesses located near another end of the cover part, wherein each cover part is adapted to be fitted at one end of the cover part to a first protection module with the first recess of the cover part received in one of the two recesses of the first protection module, and fitted at an opposite end of the cover part to a second protection module with the second recess of the cover part received in one of the two recesses of the second protection module such that in use the cover part extends across the distance which the first protection module is spaced apart from the second protection module,
- wherein each cover part is generally semi-cylindrical and has along each longitudinally extending edge a securement device configured for releasable engagement with the protection modules, wherein the securement device formed with an upturned lip sized to extend into a slot formed in a corresponding protection module for locking the cover part to the corresponding protection module when a pair of corresponding cover parts are secured to the corresponding protection module.

- and
- a plurality of cover parts, wherein each cover part is adapted to be fitted at one end of the cover part to a first protection module, and at an opposite end of the cover part to a second protection module,
- wherein each cover part is generally semi-circular and has formed along each peripheral edge a securement device configured for releasable engagement with the protection modules, and
- wherein the protection modules and cover parts are each formed near ends thereof with a recess extending around an outer surface, the recess in the cover parts being configured for receipt of a securement strap and the recess in the protection module being configured for receipt of an underside of the recess formed in the cover part so that the recesses cooperate to fix the cover parts to the protection module, and wherein the protection modules are formed with a tensioner recess in which a tensioner for tensioning the securement strap can be received, the cover parts being formed with an aperture through which the tensioner can be accessed.
