SUMMARY 

Aimed to identify the risks associated with well operations from mono-hull vessels. Is based on feed back from well operators and vessel owners involved or intending to be involved in this type of well intervention. Identifies the risks associated with general well intervention and for various complexities of well intervention operations ranging from subsea Christmas tree repairs to coiled tubing drilling and hydrocarbon storage. The main conclusions are: operations from a dynamically positioned vessel should be safer than from a moored vessel; personnel competency in all aspects of the operations from technicians to management is critical; safety and management systems must be implemented and adhered to; proper planning, procedures and contingencies are essential for safe operations; isolations and barriers must be designed to cope with all contingencies.
