AZIPODS TO HELP MERCY SHIPS ACCESS DIFFICULT HARBOURS

AZIPODS TO HELP MERCY SHIPS ACCESS DIFFICULT HARBOURS

Tuesday, June 29, 2021 

ABB’s Azipod propulsion will help hospital ship 'Global Mercy' enter less accessible harbours off the African coast, while reducing vibrations and noise – crucial to the comfort of up to 200 patients and medical personnel on board.

With about 5bn people estimated to lack access to surgical care globally, international charity Mercy Ships uses hospital vessels to make surgery and medical assistance freely available to people who have little access to healthcare. The newest Mercy Ships vessel, the world’s largest purpose-built civilian hospital ship Global Mercy, has been delivered by Tianjin Xingang Shipyard in China during an official ceremony held on June 24, 2021. Global Mercy is equipped with two Azipod propulsion units, as part of a scope of electric, digital and connected solutions to optimise operation.

With enhanced manoeuvrability enabled by 360-degree rotation, the Azipod system will help the 174m ship to navigate through narrow passages and dock in shallow harbours. With many African ports being too shallow for large ships, and with limited or lacking tugboat availability, this feature of Azipod propulsion will prove crucial for Global Mercy’s ability to deliver healthcare to those in need. Additionally, the Azipod system’s design minimises noise and vibrations, ensuring a smoother, quieter stay for patients and crew on board.

Specially designed by Deltamarin, with Stena RoRo responsible for vessel specification and project management, Global Mercy will feature six operating theatres, hospital wards for 200 patients, general outpatient facilities, ophthalmology and dental clinics, and its own laboratory. The vessel is expected to embark on its first medical air mission to sub-Saharan Africa in 2022, joining the charity’s existing vessel Africa Mercy and thus more than doubling the capacity of Mercy Ships to provide free healthcare.

“As well as offering comfort levels equivalent to a high-quality cruise vessel, hospital ships must provide surgical procedures on the basis of need, making it critical that vibrations are kept to a minimum,” said Per Westling, MD Stena RoRo. “In sea trials, the performance of ABB’s Azipod propulsion was even better than anticipated, exceeding expectations on safe return to port and offering smooth and closely controlled sailing.”

Global Mercy will change the lives of people who would otherwise have no access to high-quality healthcare, and we are honoured to be involved in such a remarkable project,” said Juha Koskela, Division President, ABB Marine & Ports. “We are confident that the performance of Azipod propulsion will contribute to the safe and successful provision of medical care on board and allow Global Mercy to support people in areas that would otherwise be too challenging to access.”

Arriving at the yard fully assembled, the Azipod system is easier to install than a traditional shaftline propulsion.

“Ease of installation of the Azipod propulsion system has been a decisive factor, as well as our previous successful collaboration with ABB on other passenger vessel projects,” said Haibo Mao, Construction Leader, Tianjin Xingang Shipyard.

In addition to the twin 2.85MW (3,821 hp) Azipod units, ABB’s scope includes generators, switchboards, transformers and drives, as well as bridge controls for the propulsion system and the ABB Ability Marine Remote Diagnostic System, which allows the prompt detection and correction of faults on board. Global Mercy will receive round-the-clock support from ABB Ability Collaborative Operations Centres.
