The MH 2-arm system is a derrick mounted pipe handling system. Typical racking board capacity of the 2-arm system is up to 420 stands of drill pipes and 14 stands of drill collar. Available with and without robotic motion control (RMC).

Intermediate racking armThe intermediate racking arm is installed between the set-backs at approximately 30 ft above the drillfloor. The arm is telescopic and slewable through approx. 180 degrees, and is mounted on a trolley that travels in or out in track beams. Designed to lift and guide drill pipe and drill collars between centre well and setbacks or vice versa. The rackerhead is mounted on an approximately 5.5 m (18 ft) long track beam for vertical guiding during lifting of the stands. The upper end of the track beam has a guide sheave for the standlift wireline.

Upper racking armThe upper racking arm is installed in between the fingerboards. It is telescopic and slewable through 180 degrees and mounted on a trolley that travels in and out in track beams. Designed to handle and guide tubulars up to 9 1/2” o.d. between centre well to racking boards or vice versa.

MH fingerboard The MH fingerboard is fully customizable and allows for the size of the board to be adapted to the available space. Based on the selected combination of rows for drill pipes, casing and drill collars tubulars virtually any setback capacity is attainable – given enough space.

Key featuresn The MH fingerboard is designed to safely lock stands in the derrick by a remotely operated system. nDrill collar stands are fixed in position by an individual locking finger for each stand. This prevents the load from the full row of drill pipe acting on one single locking finger.nEach locking finger is connected to a pneumatic cylinder by a link mechanism. All bushings are maintenance free and do not require lubrication. The operation of the pneumatic cylinder is through pneumatic valves mounted in the pneumatic power valve cabinet.nThe cylinders are pneumatic operated and have spring return to close position. The locking fingers are bolted assemblies with the actuating cylinder protected within the fingerboard structure. The polyamide hoses are also well protected, running inside the fingerboard structure.nIn order to simplify the inspection and maintenance access, the locking finger assemblies are made as separate units that are accessible from the top of the fingerboard. The complete locking finger assembly can be lifted out of fingerboard finger.nThe remote control of the fingerboard is integrated into the control system for the racking machines.nOption: can alternatively be controlled with a remote electrical panel.nOption: can alternatively be controlled with a remote pneumatic control panel.nOption: row adapters. In order to use one row for two or more different OD-sizes, mechanical row adapters can be added for specific rows.nOption: A special bottom-hole-assembly slot can be integrated in the fingerboard. This is typically mounted in a dedicated holder for quick access.nOption: Noise reducing rubber flaps. These wire- mesh reinforced rubber plates also dampen the stand movement in fingerboard.

MH mousehole

The MH mousehole is highly automated and specially designed for offline standbuilding of drill pipes, casings and collars.

Key featuresn The MH mousehole is suspended from the drillfloor

with a lower support towards the substructure. It is equipped with a watertight flange. It is hydraulically powered, supplied from the rig ringline and operated through a control system from the assistant drillers chair in driller’s cabin

n The portfolio includes both standard and telescopic type with different lengths and max. tubular diameters depending on the context of application

n The centralizer automatically closes and centralizes the tubular of different diameters

mousehole

Main models

Type Standard In principles, a long pipe consisting of main pipe, a “rabbit” with shock absorber and removable centralizer. The rabbit hoists and lowers the tubular (within the main pipe) to any desired height needed in the standbuilding operation.

Telescopic The telescopic mousehole is in principles a long pipe consisting “outerbox”, “in-nerbox” and a “rabbit”. The main purpose of the telescoping innerbox is to reduce the mousehole length when retracted for not colliding with the rig structure when the derrick is skidding or during handling of BOP.

The MH pipe deck pipe handler (PDPH) is located at pipe deck and its main purpose is to transport tubulars from pipe deck to the MH tubular feeding machine. It is controlled by a radio remote control panel, either located in a dedicated chair in drillers control room, or operator standing outside of drillers control room. The PDPH have hydraulic oil supply from the rig ring-line system. Hydraulic hoses are drawn to the PDPH through the pedestal and electrical cables are connected in the interface junction box outside the pedestal. Jib cylinders and gears are operated through the control panel.

When the PDPH is not in use, it shall be parked with the gripper yoke resting on the deck or in the jib rest located next to the derrick. This is to be used during sea voyage, bad weather or when the PDPH will not be in use for long periods. In addition, there is a parking position for the yoke, on the heavy tool landing platform.

The MH piperack crane is designed for safe transportation of tubulars from the pipe deck to the catwalk machine, and vice versa. The crane is a cantilever type crane, controlled from a cabin or platform located on the crane trolley. Remote control from the drill floor is also available. MH piperack crane is delivered with twist gripper as handling device. The control system ensures that the yoke is always kept horizontal during a sequence.

The twist gripper yoke is designed to pick up tubulars out of centre, but the load will always be kept horisontal. MH piperack crane with telescope is mainly used on rigs with small elevation differences. The telescope increases the hook up flexibility.

The innovative vertical pipe handling systems developed by Aker Solutions meets the industry’s constantly increasing demands for safety and efficiency. Based on an innovative design, the equipment can be integrated into new build rigs, or retrofitted to existing rigs.

In addition to stand building capabilities, the system is designed for handling tubulars as singles, as quadruple stands of range two or as triple stands of range three.

The fingerboard layout is based on a parallel racking configuration, which offers the large storage capacity required for deep water drilling operations.

The vertical pipe racker is based on the proven column racker design, a rotating column with guide arms at the upper and lower ends, working together with the vertically movable main gripper arm. Horisontal to vertical handling is carried out by a single joint elevator that can be attached to the main gripper arm.

The system is optimized for performing efficient pipe handling, while ensuring the safety of the rig crew in the best manner possible.

The riser handling system is a complete solution for vertical storage and handling of marine riser. The riser handling crane is designed for vertical handling of risers from the riser fingerboards to the riser chute machine where risers are conveyed to the drill floor. In addition, the crane can be designed to handle and rack the slip joint. The crane is powered from a rig main power unit with hydraulic working pressure of 210 bar (3000 psi). Hydraulic and electric power are supplied by a drag chain, allowing the crane to travel on rails port/stb. along the fingerboards.
