Construction Gets Underway on Osiris Projects' New Survey Vessel

Posted 1 March 2010

Work has recently started on Osiris Projects new build 28.0m survey vessel, to be named ‘Bibby Tethra’. ‘Tethra’ is a Celtic god, king of the Fomorians who lived in the underworld. This fits well with the Osiris theme, as Osiris was the principal Egyptian god of the underworld.

Construction of the aluminium hull is underway in St. Malo by the specialist French shipbuilder Socarenam. The shipbuilder is well known in France for their high specification military and customs vessels of various designs as well as large multi-role support vessels for the oil & gas industry, the most recent of these being delivered to the Bourbon Shipping Group in late 2009. The Osiris vessel will be delivered ready to work in late March 2011.

The new build has been made possible by the involvement of Bibby Maritime Limited, a specialist division of the Bibby Line Group, one of the oldest shipping companies in the UK. Bibby Line Limited has been in existence since the early 1800’s and currently has a wide and diverse range of successful businesses within the group. These range from traditional shipping, road distribution, financial services, supermarkets and the specialist marine divisions. Osiris Projects have agreed a 5 year initial charter deal with Bibby Maritime with an option for a further vessel of similar design already on the drawing board.

Bibby Tethra or ‘Tethra’ as she will probably be known is a very high specification purpose designed coastal survey catamaran. The vessel is based on a very distinctive small waterplane area twin hull (SWATH) design that maximises stability and seakeeping characteristics in rough and choppy sea conditions, ideal for coastal sites around the UK.

The new vessel has many advanced features that makes her ideally suited to supporting the company’s main survey activities within the Oil & Gas sector and the rapidly expanding offshore renewable energy industry. The vessel features include DP1 dynamic positioning, diesel-electric driven 360° pump jets and conventional diesel driven propellers, hull mounted multi-beam transducers, twin sonar wells, 6.5m clearance hydraulic ‘A’ frame, 18 tonne/metre crane, dedicated instrument winches, moon pool, comfortable accommodation for up to 16 marine and survey crew and lots more.

The SWATH design has been proven in many applications worldwide and will allow the Tethra to operate and collect high quality survey data in sea conditions well above the working limits of any existing vessels of comparable size or many significantly larger survey vessels.
