Equipment
Conbit supplied all the sling arrangements and the rigging components. The main item was the sling configuration with an SWL of 55 tonnes. Conbit also provided the material and equipment required for seafastening and load spreading. The load spreading was required on board the supply vessel and on the quayside.
Crew
Conbit provided lifting supervision during the load out when the module arrived at the quayside in Den Helder, during the load out onto the barge, during the sea transport and during the offshore lifting work. Conbit’s highly skilled lifting supervisors are experienced with all kinds of lift. However, the offshore lift is definitely the most challenging projects. The offshore lifts require a good sense of the motions in combination with the available lifting speed. Most of Conbit’s offshore lifts are performed using high speed winches, but in this project the available winch needed to be used.
Engineering support
Conbit prepared the following procedures and engineering documents:
- Load out plan
- Seafastening plan
- Lift / installation plan
Assets
The supply vessel “Island Endeavour” was used for the transport. The module was located at the aft of the vessel to maximise the distance between the vessel and the rig legs. The drill rig in the field was Paragon HZ1 (formerly known as Noble George Sauvageau). The well is located in the K18 field, which is a concession owned and operated by Wintershall.
