Thordon Bearings reports increasing demand for its COMPAC water-lubricated propeller shaft bearings, as superyacht operators and managers opt for more environmentally friendly propulsion solutions.

Since the first installation of its system to the 2007 Italian-built 1540 metres (5053 feet) long Savarona superyacht, Thordon Bearings now has more than forty superyacht references for the award-winning COMPAC system, the most recent of which being the Blue Bird of 1938.

Clean propulsion solutions

The 31.6 metres (104 feet) motor yacht was retrofitted with a 105 mm (4.1 inches) COMPAC bearing, during an extensive refit at Astilleros De Mallorca, Spain.

We have seen a substantial increase in the number of yacht builders and repairers specifying COMPAC, especially in Europe,” said Thordon Bearings’ Vice President (VP) of Business Development, Craig Carter.

Global superyacht industry is booming

The superyacht industry is booming, with new-build tonnage expected to increase fourfold

Despite the sanctions imposed on Russian oligarchs, the superyacht industry is booming, with new-build tonnage expected to increase fourfold, as companies invest in vessels to operate under charter. This combined with a flurry of orders from traditional buyers has pushed the global order book for vessels of 100 metres (328 feet) in length or more to 27, with shipbuilders at full capacity until 2025. All told more than 1200 vessels are on order, according to analysts.

Craig Carter adds, “It is apparent that owners and operators are now investing in technology and systems designed to reduce the environmental impact, by replacing conventional oil lubricated bearings with the more environmentally friendly seawater lubricated alternative, as part of their sustainability goals.

COMPAC bearing system

Thordon Bearings’ COMPAC bearing system uses seawater as the lubrication medium, in place of oil. Seawater is taken from the sea, pumped through a polymer COMPAC propeller shaft bearing and returned to the sea.

The technology is the bearing system of choice for cruise ship owners and over 50 of the world’s navies and coast guards. With minimal wear rates and zero pollution risk, many users have been operating with the same bearings for more than 20 years.

Environmentally friendly system

Since 2020, Thordon Bearings has installed COMPAC to some 15 superyachts, with shaft diameters ranging from 105 mm (4.1 inches) to 320 mm (12.6 inches). Projects include Jester, Pacific, Mgambo, Dytan, Valeri, Annamia, and Aura.
