Colombo was the automatic choice of Global Offshore Services Ltd. India, for their conversion/repair requirements to ready the Offshore Support Vessel (OSV) Shergar to meet with the stringent Petobras charter requirements.

This project was awarded to Colombo Dockyard as a result of successful completion of OSV Kailash also owned by the same owners during June 2011.  

The offshore Support vessel Shergar owned by Global Offshore Services Ltd. India was accommodated for major drydocking and lay up repairs during July 2012.  The vessel was accommodated in Drydock No. 04 during this call.

The vessel was operating in the Indian waters; therefore Colombo was the best choice for them given the track record of the yard on similar repair / upgrading jobs. Colombo’s flexibility to accommodate owners requirements, flexible approach to tackling the last minute modifications required by charters and timely completed final repair output to meet with classification society guidelines.

Colombo Dockyard’s proven track record for repairs and shipbuilding specialising in sophisticated DP 2 enabled offshore support vessels to the international market, enhances the shipyard’s attractiveness to international ship owners looking for conversion/retrofitting repair requirements in this territory.

Colombo’s strategic geographic position also plays a part, as the owners can place the vessel easily for their next employment in the Indian Ocean or shift to the Atlantic or Pacific oceans.    

During this call the owners were preparing the vessel for her next charter in Brazil, key systems were upgraded during this repair call, tanks were converted to meet the new charterer requirements as well.
