World's largest ship equipped with motors from Hoyer

Hoyer Motors has supplied motors for the hydraulic system on the world's largest ship Pioneering Spirit, which recently arrived in Rotterdam, Holland. The enormous vessel is designed to transport entire offshore platforms and can lift loads of up to an impressive 48,000 tonnes.

At 382 metres long and 124 metres wide, Pioneering Spirit is the world’s largest ship and consists of two massive vessels that have been joined in the middle by the ship’s enormous lifting mechanism. The ship is designed to lift and transport entire offshore platforms on the open sea. Hoyer supplied 34 motors for the ship, including eight 500 kW motors to be used in the centre hydraulic power unit, which controls the hydraulic system in the ship’s main power unit, leak oil pumps and boost pumps etc.

“Hoyer Motors was already in contact with the partners involved in the ship’s construction in 2009, when the design was being developed. That’s one of the reasons why Hoyer opened an office in Holland that year, to be able to work even closer with local clients,” recounts Maarten de Beun, Hoyer Motors’ Country Manager in Holland, who continues:

“Our efforts have since borne fruit, and back in 2011 we received the order for the 34 motors that would be used for the ship. All of the motors are tested and classified by the independent Lloyd’s Register of Shipping, which ensures that they meet strict international requirements.”

Previously, a dangerous operation

Offshore platforms are large, unwieldy things, and they are installed on the open sea. Previously, the top half of the platform had to be manually separated so that the individual pieces could then be installed at sea. This meant that workers had to separate the platform into pieces that could be lifted by conventional cranes, which was time-consuming and potentially hazardous work that carried with it the risk of oil and gas spills.

Greater safety at sea

Pioneering Spirit has the capacity to lift and transport entire platforms or their top halves, and the ship is capable of installing them as a single piece. The ship’s impressive lifting mechanism has a carrying capacity of up to 48,000 tonnes – a figure which corresponds to 80 fully loaded Airbus A380 passenger planes.

This makes it significantly less dangerous to ship and install platforms at sea, as the lifting mechanism’s advanced hydraulics compensate for the rocking of the ocean and keeps the platform level throughout the entire process. The hydraulic system also make it possible to perform lifting operations without prior knowledge of a platform’s weight or centre of gravity, and it enables the ship to lift platforms even in poor weather conditions.
