The scope of testing covered engine performance, fuel consumption, navigation and radio equipment, manoeuvrability, speed tests and safety systems.

Being built by Stena RoRo on behalf of international charity organisation Mercy Ships, the vessel is said to be the world’s largest civilian hospital ship.

The vessel will now prepare to commence its maiden voyage to Belgium for the installation of the provided medical equipment.

In 2015, vessel construction started at the Tianjin Xingang Shipyard in China.

Since 2013, Swedish Stena RoRo has been responsible for the design, contracting and execution of this project.

Stena RoRo CEO Per Westling said: “The purpose of a sea trial is to ensure that the ship’s systems are working properly during operation and that the requirements of the specifications and applicable standards are met.

“The hospital services to be provided on the Global Mercy entail increased requirements for good ventilation and minimisation of vibrations, for example. This was also checked and she was approved on all counts.”

The vessel will feature six operating theatres, a laboratory, 200 hospital beds, a patient clinic, and an eye and dental clinic.

Global Mercy will have the capacity to accommodate around 950 people, including 641 crew members.

With a gross weight of 37,000t, the 174m-long ship has been designed to be a Passenger Ship-class vessel.

This vessel features a service speed of 12k and a design draft of 6.15m.

Apart from Stena RoRo, several subcontractors worldwide were involved in this project.

Finnish Deltamarin was responsible for design work while France-based Barry Rogliano Salles (BRS Group) helped in preparing the contract.

Global Mercy has been classified by the Lloyd’s Register in the UK. It has been flagged by Malta and will initially operate along the coast of Africa.

The ship is expected to work on its first mission in Senegal next year.
