Case Study

Santos Ningaloo Vision FPSO

Santos Ningaloo Vision FPSO

The Ningaloo Vision FPSO is located on the Northwest Shelf of Australia in 341m and has a storage capacity of 540,000 bbl. The FPSO operates in cyclonic area and has a disconnectable internal turret.

The Challenge

IntecSea has been involved in the Ningaloo Vision FPSO project since its conception in 2006, for which we acted as an engineering services provider and a reviewer. This was followed by engineering services throughout the FPSO conversion, installation and subsequent upgrades and modifications, including the vessel hull, marine systems, the mooring system, and now, eight years of operations.  

IntecSea has provided a broad range of specialists to the client, including acting as the client’s engineers during the initial design phase, and later as part of the client team during the conversion of the selected tanker into FPSO and through installation and operation startup.  

Our Approach

In 2011 the vessel suffered mooring damage to one of the mooring legs. IntecSea provided rapid response and carried out time-critical engineering assessment of the system to allow the client to continue safe operation in the impaired condition. Subsequent support included identification of the root cause of the failure and development of proposals for the repair method.

Between 2012 and 2015 IntecSea provided engineering services and formed part of the client’s team to undertake the necessary detailed design engineering and project management support for the refurbishment and upgrade of the FPSO in preparation for tie-back to additional fields. This included significant hull steel life extension scopes, engineering change modifications, design of new topside equipment, and various other engineering tasks. 

Value Delivered

IntecSea has a uniquely broad range of specialists within the marine disciplines, supported by the topsides capabilities from Advisian and Worley; this allowed us to provide the necessary and discipline specific or combined multidisciplinary support as and when it was required, whether it be in our offices, in the client’s offices, offshore, or in the shipyard. 

Due to the on-going relationship with the client, IntecSea personnel are familiar with the facility and have analytical models of the asset, including hull, mooring (disconnectable mooring buoy) and risers, in place enabling a quick response to any queries or requests for evaluations. This is especially important in providing valuable decision support in time critical situations.
