( 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

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
