In an initiative set to be transformational for ship design while protecting the oceans from pollution, Thordon Bearings and Wärtsilä have announced the formation of the Blue Ocean Alliance to develop and promote the revolutionary sterntube-less ship concept.
The Blue Ocean Alliance brings together unrivalled maritime industry expertise, with seawater-lubricated bearings pioneer Thordon Bearings, systems integrator Wärtsilä, the School of Naval Architecture & Marine Engineering of the National Technical University of Athens(NTUA), naval architect SDARI(Shanghai Merchant Ship Design & Research Institute CSSC) and classification society, ABS, who championed the initiative in 2019.
The concept of a ship design that does not require a sterntube and eliminates the need for oil-lubricated sterntube seals and bearings is revolutionary. The design is also likely to save ship owners hundreds of thousands of dollars in capital and operational expenditure over a vessel’s lifespan, including zero requirement for lubricating oil or biodegradable lubricants.
ABS has estimated that in a sterntube-less ship design, a two-week dry-dock re-alignment or bearing and seal replacement job, can instead be completed in a single day while the vessel is afloat.
Ship designer SDARI, in partnership with Thordon and NTUA, has already been granted an Approval in Principle(AIP) from ABS for the concept design of the sterntube-less vessel with Thordon’s COMPAC Split Seawater-Lubricated Aft Bearing. ABS is further developing a pertinent Guide and Notation for such a ship.
Thordon is calling the concept T-BOSS(Thordon-Blue Ocean Stern Space), a revolutionary sterntube-less propeller shaft system design, in which the vessel’s sterntube cooling tank is replaced with a dry irregularly shaped chamber, thus allowing for inspection and maintenance of a seawater-lubricated single bearing and seal from inside the ship, while afloat, without any need to withdraw the shaft.
The T-BOSS utilizes Thordon’s award-winning seawater-lubricated COMPAC propeller shaft bearing system and the Wärtsilä Enviroguard Seal, which requires no maintenance between planned overhauls of up to five years. As well as eliminating the need to withdraw the propeller shaft for the lifetime of the ship, the COMPAC bearing comes with a lifetime bearing wearlife guarantee.
Thordon and its partners strive to shape the decarbonization of the marine and energy sectors, with products and solutions that provide efficiency, reliability, safety and environmental performance.
