Platform Case Study

Crane winch replacement

Safely extending crane working life


A North Sea Operator was looking to extend the working life of the main crane on their platform. They consulted MDL who inspected the asset to model different scenarios to ensure continued safe operations. From these scenarios the Operator identified winch replacement as the most efficient approach to safely extending the crane’s working life.

MDL Solution

Following the on-board survey, MDL Asset Maintenance & Engineering team returned to the office and engineered the technical documentation deliverables. This included storyboard method statements, lift plans, offshore implementation work pack, commissioning, load testing and wire rope change-out procedures. The scope included the delivery of the new winch and spare parts, where MDL teams could carry out a complete interface and dimensional survey of the components to de-risk the offshore scope of work.


The MDL team carried out various pre-job briefings and site familiarisations before executing the change-out on the platform with a temporary crane. This proven solution ensured minimal downtime for the only platform crane to get the asset returned to service within 2 weeks of mobilising on board. MDL further added value by identifying a historical functional control system issue on the crane, and resolving it prior to demobbing and safely closing out the client’s MOC.
