Date: 5 April 2011


Reef Subsea AS, an associated company of GC Rieber Shipping, has decided to divest from its Bluestone Offshore Pte Ltd business based in Singapore. Bluestone is an integrated geotechnical site investigation company providing complete solutions for offshore projects requiring seabed data and sampling. Upon a Share Purchase Agreement signed on 4 April 2011, Fugro will acquire 100% of the company. The parties have agreed to not disclose the sales price.


Reef Subsea's decision to divest from the geotechnical market follows the company's decision to concentrate the strategy around subsea services. The divestment will provide Reef Subsea with additional resources to further pursue its developments in the global subsea market. Reef Subsea's presence in Asia-Pacific will be assured by the subsidiary Scanmudring's new office in Singapore.


The "Greatship Maya", a subsea vessel operated by GC Rieber Shipping, is currently employed on a time charter agreement with Bluestone Offshore. This time charter agreement, which expires in 2012, will continue unaffected by Reef Subsea's divestment from Bluestone Offshore.
