1. Production and Maintenance Related Services  
 

1.1 Crane Division
Rabutec has established crane services & workshop support facilities at Port Klang near Kuala Lumpur and at Tuas, Singapore. With the setting up of these service centres and the establishment of an in-house engineering department, Rabutec is able to provide comprehensive technical and services support for crane and lifting operations.

Our services include:
Refurbishment, repair and recertification of cranes
Supply of crane related parts and accessories
Maintenance and operations of cranes
Supply of API Marine Cranes and crane component
   

Rabutec is one of the larger crane refurbishment companies in the region. With our newly acquired facilities, the company has the ability to simultaneously refurbish 30 offshore cranes of all capacities (5 ton to 250 ton) per year. Our well trained technical teams include crane specialists, certified crane inspectors, hydraulics and mechanical specialists, and structural engineers.

Our engineering department is well equipped with latest high end engineering software to support the design services which are proactive with operational requirements. Software in our inventory includes Autocad, Inventor Pro, Nastran, Ansys, and AQua. The softwares are operated by a talented team of experienced engineers and draftsmen. 

Rabutec’s manufacturing capability has also been further enabled by the establishment of a licensed assembly/manufacturing agreement and collaboration with Global Techcrane Corporation of US. Rabutec is now also able to design, build and supply offshore marine API cranes to the oil & gas industries.


 
 

1.2 Refurbishment Process
Crane Refurbishment Process:

( i ) Cranes are completely disassembled and all the crane components are stripped down.
( ii ) Procedures for refurbishment is approved by independent certification or classification bodies like ABS, DNV, Lloyd’s or SGS.
( iii )

Defective parts are identified, repaired or changed. Only OEM or certifiable parts are used.

( iv ) Structural refurbishment includes MPI. Surface preparation and Refurbishment are in accordance to API standards including the application of a 3 coat marine paint system.
( v ) All refurbished components are tested and recertified as per applicable procedures. All parts purchased new are with certificates.
( vi ) Crane Components are reassembled. Crane is assembled and function tested.
( vii ) Crane is installed on the facility / vessel and load tested. Certification by applicable independent class or certifying body.

2. Design and Manufacture of Custom Equipment  
 
 

2.1 Design, Fabrication, Assembly and Commissioning of Gangways (including heave compensated gangways)
Our R&D department is continuously tasked with finding new innovative solutions for operational challenges as the industry move towards hasher environment. In line with this, we have recently designed our own heave compensated gangways which are applicable in marine vessels, FPSO’s, and other floaters. Our gangways are light in design with operator friendly safety features. Rabutec manufactured gangway meets all applicable design and marine standards. The first gangway is now being built for an FPSO and is expected to be manufactured in around 7 months. Rabutec designed and manufactured gangway are not only safe and easy to use but are resilient, suitable for harsh environment and cost effective.

Heave Compensated Gangways:

The diesel engine powered hydraulic operated telescopic personnel walkway(called Gangway herein) is designed to be used to transfer personnel between a support vessel and a fixed platform.

 

Principal Dimensions

  Walkway Width 1.2m
  Maximum Extended Length 34.5m
  Mean Operation Length 29.5m
  Complete Retracted Length 24.5m
  Normal Operation Area 29.5m+ / -3.0m
  First Alarm Area 29.5m+ / -3.0 - 3.8m
  Second Alarm Area 29.5m+ / -3.8 - 4.6m
  Emergency Lift off Limits 29.5m+ / -4.6m
 

(Measured from centre of pedestal to end of Landing area).

   

The walkway is connected to the vessel by lifting the walkway from the park position and utilising the electro-hydraulic controls, manoeuvring the walkway so that the free end is placed on the fixed structure. Once landing has been completed, the walkway automatically enters free-floating mode.

The Gangway is self-sufficient in all its operations and is able to self-stow while not in use or in emergency conditions.

 

Main operating condition, walkway supported at both ends

  Load on walkway 3 kN/m2
  Wind 25 m/s
     
Emergency situation with walkway supported at one end only
  Load on walkway 1.5 kN/m2
  Wind

50 m/s

     
The walkway has three movement planes, slewing, luffing and telescoping. It is designed when connected between support vessel and fixed platform to remove the relative movements between the two installations.
 

The gangway will be able to do the following motions namely

  Slewing 270 or 360 degrees (TBD)
  Luffing +24 deg to -16.5 deg
  Telescoping 10m end to end
     

The walkway assembly consists of three primary components; these being the steel pedestal support structure, the rotating turret complete with A-Frame and hydraulic cylinders, and the telescoping bridge section (will be of Aluminium construction). The telescopic bridge section comprises a number of sub assemblies: one fixed outer bridge section, one telescoping inner bridge section, landing cone/shock absorber and access stairs assembly.

Once the walkway is in contact with the fixed installation (a shock absorber is located at the end of the bridge section and provides, within the landing cone the interface between the walkway and the fixed installation), the hydraulic system is automatically free-coupled and the walkway will follow the relative motion of the vessel and platform.

 

The walkway os designed to be in compliance with the following rules and certifying bodies

CNR UNI
NMD Draft 5
AWS D1-1
ASTM

AISC

RINA
Lloyd’s Register of Shipping
DnV – Rules for the Construction and Classification of Offshore Mobile Units
