Task D-13 Services vessels and components
Task Descriptor
Boilermakers help to ensure the proper operation of vessels and components by verifying their integrity, repairing or replacing them when needed as per codes and jurisdictional regulations. Modifying and upgrading existing systems entails replacing components and materials to improve performance or reliability and can be done during scheduled and unscheduled maintenance. Sometimes, vessels and components cannot be repaired and need to be replaced.
Boilermakers need to know when rigging, fitting and cranes are needed to accomplish the tasks.
Inspecting and testing are important to identify defective and worn components to ensure that the system has been constructed or repaired properly.
