BOP Transporter/ Two-Stack   system The BOP “Forklift” Transporter shown can be used for a “twostack system” with the main frame design allowing a skiddingsystem to be adopted for placing the BOP stack(s) alongsidethe transporter on the cellar deck storage area.Capacities for the equipment range from 170mT to 400 mT (187- 440 tons) with lifting heights from 3.0 m to 10.0 m (10 - 33 ft). BOP Trolley   for one/two   stack system The BOP Trolley shown allows the stack to be transported fromthe parked position to the well centre along the moonpool orvice versa and is generally used together with an overhead craneof the same capacity as the trolley to allow the stack to be liftedto the storage position. Overhead Cranes/Gantry Cranes The Overhead Cranes/Gantry Cranes are designed to suit thecustomer’s requirements. Both hydraulic and electro hydrauliccranes are available. The latter option includes an on-board powerunit. Most units can be designed with transverse travel, althoughthis may be limited by rail span and height. The controls are usu-ally cabin mounted or pendant.See page 40 for information on Access Baskets. MH delivers simple Gantry Cranes with capacities ranging from 5.5 mT (6.1 tons) to full size overhead cranes with capacities up to 250 mT (275 tons).  4 84 84 84 84 8 maritime hydraulicsmaritime hydraulicsmaritime hydraulicsmaritime hydraulicsmaritime hydraulicswww.marhyd.comwww.marhyd.comwww.marhyd.comwww.marhyd.comwww.marhyd.com BOP Carrier The BOP Carrier is installed on each side of the moon pool andthe BOP is located on foldable hang of   arms in between the twounits.The folded BOP Carrier is able to pass a BOP in the wellcentre.The two independent units are driven by rack & pinionalong the moon pool, and lifting is performed by hydraulic cylin-ders.Both travel and lifting functions are controlled by a PLC program.The BOP Carrier is equipped with a wireless remote control.This BOP Carrier is very light and requires less space in themoon pool area than other solutions. Technical data Capacity150 mT (165 tons) SWLLength2400 mm (7.9 ft)Height8000 mm (26 ft)Width3000 mm (10 ft)Weight40 mT (44 tons)Travel speed1 m/min (3.3 ft/min)Lifting speed1 m/min (3.3 ft/min) BOP Transporter Technical data Capacity400 mT (440 tons) SWLLifting heightup to 9m (30 ft)Includes sliding retractable test stump arrangement.Mechanical safety locking system. BOP Carrier Assembly BOP Transporter  BOP Guide Systems The Guide Systems provide guidance and horizontal restraint forthe BOP when being lifted by the drawworks. Guide systemscan be adapted to either Transporter or Overhead Crane Sys-tems, and mounted on deck, under deck, or connected to thetransporter. The systems can be fixed, hinged, or sliding. Bothconventional tube spear type systems and rubber buffer rollertype systems are available. Base Plate Trolleys The Base Plate Trolleys are designed as auxiliaries to mostsystems, and their main function is to handle temporary andpermanent guide bases. The Trolleys are strong enough to supportthe LMRP. Their unique design allows the unit to enter withinthe guide lines, making trolleys ideal as a service platform at thedrill string centre.The Trolleys can be adapted for handling BOP’s and X-mas treeswith capacities ranging from 30 mT to 300 mT (33 - 330 tons).
