Thruster Replacement

Quick Enquiry

Thrusters are a key component of a Dynamic Positioning operation of floating offshore assets. Due to their operation in challenging subsea conditions, frequent replacement is required to ensure reliable functioning of the thrusters.

With a typical thruster weight ranging from 20 to 50 tonnes, the replacement operation is a complex and potentially hazardous operation. Traditionally, floating assets are dry-docked to carry out the replacement of the thrusters. This is an exceptionally costly operation, taking into consideration all facets of the project, such as demobilization from the offshore field, rent of the dry-dock facilities, and the loss of operating revenue.
