With limited drydock availability, Wightlink faced a challenge in exchanging a Voith Schneider Propeller (VSP) on the RO-PAX ferry, St Clare.

Wightlink needed a safe solution with no margin for error.

Houlder focused on ensuring the vessel's stability. Our team conducted detailed calculations of the ship’s condition.

To achieve the required clearance above the waterline, water bags were placed on the aft deck. A total of 227 tonnes of ballast maintained watertight integrity.

Our calculations were accurate, providing the trim needed to maintain clearance during the VSP removal.
