The product line reposes on a fixed stand post or riser and is connected by an inner and an outer arm – both arms are movable parts. Balancing is needed due to the weight of the steel piping. Balancing of the Marine Loading Arm is done by a rotating counterweight, which is connected to the inner arm and the outer arm via a rigid pantograph ...
Drilling riser joints with buoyancy modules. A drilling riser is a conduit that provides a temporary extension of a subsea oil well to a surface drilling facility. Drilling risers are categorised into two types: marine drilling risers used with subsea blowout preventer (BOP) and generally used by floating drilling vessels; and tie-back drilling risers used with a surface BOP and generally ...
BOPs on offshore rigs are mounted below the rig deck. Subsea BOPs are connected to the offshore rig above by a drilling riser that provides a continuous pathway for the drill string and fluids emanating from the wellbore. In effect, a riser extends the wellbore to the rig. Blowout preventers do not always function correctly.
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in a vehicle. Tie rods and anchor plates in the ruins of Coventry Cathedral
2) Rod hanger: It is a static restraint i.e. it is designed to withstand tensile load only (no compression load should be exerted on it, in such case buckling may take place). It is rigid vertical type support provide from top only. It consists of clamp, eye nut, tie rod, beam attachment. Selection of rod hanger depends on pipe size, load ...
Hatch coaming (bottom right) on a bugeye. Coaming is any vertical surface on a ship designed to deflect or prevent entry of water. It usually consists of a raised section of deck plating around an opening, such as a cargo hatch. Coamings also provide a frame onto which to fit a hatch cover.
The open hatch bulk carrier, often referred to as OHBC or conbulker, is designed to offer direct access to the hold through cargo hatches which extend the full width of the vessel. As a result, large cargo units can be lowered into place. If it is possible, the holds or hatches are designed around standard cargo unit sizes.
A gunport is an opening in the side of the hull of a ship, above the waterline, which allows the muzzle of artillery pieces mounted on the gun deck to fire outside. The origin of this technology is not precisely known, but can be traced back to the late 15th century, with the appearance of artillery in naval warfare .
