Malaysia-based international offshore energy facilities and services provider (due to commercial interests the client has requested to remain anonymous)
To operate in the United Kingdom Continental Shelf (UKCS), our client needed to have an asset integrity management strategy (AIMS) in place for the FPSO to ensure the integrity of the facility was maintained during deployment and continuous operation.
Fully meeting the requirements of being the Duty Holder of an offshore installation operating within the UK meant the client’s compliance assurance management system (CAMS) had to conform with specific European and UK legislative requirements. Failure to meet these requirements would have made it difficult for the client to facilitate the safe and continuous operation of the FPSO in UK territorial waters.
How we helped
We provided full project management support in the bid to meet full Duty Holder specifications. The production of a risk based inspection (RBI) strategy and inspection plan (including methodology) by our expert team embraced UKCS best practice, including all relevant statutory instructions and guidance from Health and Safety Executive.
The lifting appliances considered in the review were mostly new pieces of equipment being introduced into service for the first time. The data available included design specification, manufacturer's datasheets, test certificates, general arrangement drawings, test plans, and so on. By reviewing and manipulating this data, we also defined a risk assessment matrix based on the probability and consequence of failure of critical elements of each lifting appliance.
- Project management
- Review of existing procedures and processes
- Data gathering
- Data review and manipulation
- Failure modes and effects for safety critical equipment
- Risk based inspection
- Generation of a written scheme of examination (WSE) including inspection plans
- Solutions for all Duty Holder requirement challenges advised implemented resulting in the safe and continuous operation of the FPSO in UK territorial waters.
- The general risk level attributed to the majority of the lifting appliances on the FPSO (including components and elements) were moderate, thereby producing a base interval of one year for frequency of inspection. This was considered appropriate due to the level of risk involved and exposure to failure modes.
- Our qualitative risk assessment considered factors such as overload, mechanical damage, wear, corrosion, fatigue and inappropriate use of lifting appliances which ensured all parts of the equipment upon which safety depends were thoroughly examined at such a frequency that enabled defects to be detected and remedial action taken immediately.
- The examination scheme and inspection frequency developed by LR ensured the safe operation of lifting appliances in accordance with the Lifting Operations and Lifting Equipment Regulations LOLER 1998, including reference also to the Technical Guidance on the safe use of lifting equipment offshore HSG221.
- Annual inspection frequency on the Turret Crane and the Excellift Trolley, rather than the regulatory six months’ periodic inspections, resulted in significant examination cost reduction.
- Inspection costs are expected to reduce by 50% over the first five years of the equipment’s service.
- Inspections focused on safety critical areas
- Decreased inspection frequency
- Reduced inspection costs
- Assurance that lifting equipment was safe and complied with regulations
