Refurbishment of 10 Ton Mitsubishi Crane to include Man-Riding Capability and Supply, Installation of a new Electric HPU.
The Provision Crane on board a vessel (Mitsubishi Hose Handling Crane) was originally designed to be a 10 Ton crane, for handling hoses only. The owner of the vessel was contracted to convert and deliver the vessel as an FSO to an offshore oil company. As part of the requirements, they needed a man riding crane on board for personnel transfer. Rabutec was contracted to retrofit the crane such that man riding capabilities can be achieved as well as supply a new independent HPU.
The following works were carried out on the crane:
- To supply and install a man riding winch (Braden winch) capable of man riding capacity of 1.25 M
- To supply and install a new electric HPU including slip ring
- To refurbish and renew slew post/turret, main winch, slew motor and all hydraulic fittings/connections and control equipment
- To design, fabricate and install HPU deck, fly jib, winch base and operator cabin extension.
The works on the crane was carried out in accordance to API 2C and ABS guidelines for lifting equipment. The works was completed within 2 months. The crane was successfully load tested in the presence of Bureau Veritas.
