The Sea Spirit's State-of-the-Art Stabilizers

Polar adventurers aboard Poseidon Expedition’s 114-passenger vessel Sea Spirit will now benefit from advanced technology when the ship is equipped with new retractable fin stabilizers next year.

The 4,200-GRT vessel will be retrofitted with Rolls-Royce Zero Speed Stabilizers during the scheduled dry dock in May 2019 in Lisbon, Portugal, just prior to the commencement of the 2019 Arctic season.

According to Poseidon Expeditions’ Senior Director of Cruise Operations Nikolay Zakharov, “These new stabilizers will provide high-performance roll damping when the Sea Spirit is underway, while drifting, or even at anchor. They incorporate a time-tested trailing edge design that eliminates vibration and noise. At the same time, they look to the future with safeguards to protect the polar ecosystems. The stabilizers are fully compatible with environmentally acceptable lubricants (EAL) and feature quad main seals for additional redundancy.

“The current Blohm & Voss stabilizers have served us well, but the new Rolls-Royce system uses a computer-based programmable logic controller (PLC) that develops different algorithms depending on conditions. The result will be a ride for our passengers as comfortable as aboard any expedition ship currently coming into the market,” he said.

The improvements will be made at the same time that the Sea Spirit will be re-certified for new IMO Polar Code requirements. Currently, the vessel has all valid technical and international certificates complying with IMO conventions to provide tourism activities in polar waters. Along with the technical improvements, more than $2.5 million in refurbishments to passenger areas – all cabins and public areas – have been made over the past few years to the Sea Spirit.
