RRS Discovery

The Royal Research Ship Discovery is designed to support the multidisciplinary research required for the 21st century. The ship is the fourth vessel to bear the name and continues the tradition of oceanographic research at sea. RRS Discovery was delivered to NERC on the 8th July 2013 by builders CNP Freire, SA from Vigo in northern Spain. She is currently undergoing sea trials with scientific research due to start in 2014.

The RRS Discovery leaving portDesigned by Skipsteknisk AS, a leader in the design of sophisticated and noise reduced research vessels who also designed RRS James Cook, this new ship will operate worldwide, with more modern facilities and in higher sea-states, than the previous RRS Discovery Read more about the RRS Discovery Replacement Project

The RRS Discovery comes with sub-bottom profiling and multi-beam equipment for mapping the seabed, whilst her dynamic positioning capability means Remotely Operated Vehicles such as Isis can be used. Her wide range of cranes and overside gantries, with associated winches and wires, will allow many different types of equipment to be deployed from the ship. These facilities and the many more listed below help support the UK marine science community as it undertakes research of national and global importance.

Scientific Facilities

Handling Systems

The RRS Discovery is fitted with a range of handling systems, allowing operations to be conducted from both the starboard side of the ship and the stern. Provision of two separate systems on the starboard side will enable both to be rigged with working cables simultaneously, which will facilitate swapping of differing operations between the two deployment points seamlessly.

The RRS Discovery is also fitted with a comprehensive suite of winches similar to those on the RRS James Cook.

Laboratories

A range of laboratory spaces that can be flexibly configured to support a range of differing scientific activities on each cruise are provided.

Permanently Fitted Sensors/Instrumentation

The RRS Discovery is configured with a suite of state-of-the-art sensors, as well as a modern computerized data logging and distribution system.

Hydroacoustic Suite

The hydroacoustic suite is one of the most important components of the RRS Discovery’s sensor outfit. These sensors are mounted in two main areas: the large bottom mapping multibeam echosounder transducer is fitted in a novel design bottom ‘blister’, while a range of other acoustic instruments are fitted within two drop keels.

Bridge Equipment

RRS Discovery is one of the most sophisticated research ships afloat and has been designed  and commissioned with a full suite of modern navigation and communications systems, including a dynamic positioning system. Read more about Bridge equipment

Propulsion

The ship is configured with a novel azimuth thruster propulsion system configuration compared to a conventional fixed shafts/propellers and rudders. The thrusters can be independently rotated through 360° which will make the vessel extremely manoeuvrable. This configuration has also been selected with fuel efficiency in mind, while the ship is also some 10 metres longer (and slightly narrower) than the RRS James Cook, the additional length also contributes to fuel efficiency.
