The customer operates a Drillship with 3 older Liebherr Offshore Cranes, type BOS 65/550D (x1) and BOS 30/300D (x2). The steel construction, especially the lattice boom was suffering from corrosion and a rebuild was needed. The required rebuild also includes control system and component overhaul. Additionally, a fairly new Liebherr King Post Crane type MTC 1400/50 is on the drillship.

An Alatas Senior Offshore Crane Service Engineer carried out a detailed crane condition evaluation and assessment of all crane systems.
An Alatas Structural Crane Engineer evaluated the structural condition of the cranes.
Alatas provided the customer with a complete crane evaluation report and forwarded repair recommendations that included major component repair proposals.
Alatas supplied all crane spare parts and ABS class certified materials for the boom repair, as well as other materials for the steel repairs.
Alatas provided a ABS Class approved repair procedure for the crane boom repairs.
A Structural Crane Engineer was mobilized to supervise boom steel repairs and crane structural repairs.
Structural Crane Engineers, Welding Inspectors, ABS certified welders and fabricators mobilized by Alatas completed all required repairs. (total: more than 20 people on 2 shifts, working 24 hours).
The crane repairs were completed well within the target budget and time line and approved by Class Society ABS and the state owned oil company PDVSA (Petróleos de Venezuela S.A.).
The customer was delighted with the crane repairs carried out by Alatas and received the following praise from the rig manager: "On behalf of all of us here with PetroSaudi in Venezuela I want to thank you and all of your people in ALATAS, and those from MARZ, for the excellent performance demonstrated on the repair of the cranes on our Drillship. Norbert was a fantastic leader, with Leroy, of great crews and I really believe that not many people would have bet a penny on having these cranes ready in the timespan in which you all did this - Thank You All !"
