As a subcontractor for Babcock International Group, Hamworthy Pumps will supply the pump solutions for five Type 31 Frigates.

By 2028, Babcock International Group will have built five new Type 31 frigates for the United Kingdom’s Royal Navy, and Hamworthy Pumps will supply the pump solutions.

“The Hamworthy business was founded in 1914 on Poole Quay in Dorset, and we are proud to once again have the opportunity to contribute to an important frigate programme in the United Kingdom. We are currently expanding our Poole capabilities, and this order shows that we have the right setup to handle large and complex projects in the region,” says Jim McGookin, key account manager at Hamworthy Pumps and responsible for the collaboration with Babcock International Group.

The Babcock International Group contract includes the delivery of a total of 235 pumps over a five-year period.

According to the newly appointed CEO, Hans Christiaan Laheij, the Type 31 programme will be an important reference in the coming years, with Hamworthy Pumps further increasing its focus on the Navy segment.

“Hamworthy Pumps has a long history as a supplier for naval projects and a significant installed base on military ships in the USA, Canada and the Netherlands, among others. In addition to the contract for the Type 31 frigates, we also have significant contracts for new ships for the US Navy. It gives us an excellent position to be considered for other upcoming naval projects,” says Hans Christiaan Laheij.

For example, a key element of the Type 31 programme is to supply a design with the potential to secure a range of export orders and thereby supporting the UK economy and UK jobs.

“If international customers wish to develop local build and support capabilities, Hamworthy Pumps will support a collaboration approach with a range of export strategies to maximise local in-country content.”

The Type 31 programme consists of five general purpose frigates with a planned production cost of £250 million per unit. The Type 31 31 builds upon the already successful Iver Huitfeldt frigate design, incorporating changes to provide a compliant and adaptable modern platform.

In the good old days we use to get excited about the weaponry fitted to new warships, today we excited about the pumps to be fitted.

Ron5

We are?

Gunbuster

Depends If you are a Weaponeer, Pinkie, Greenie or a Clanky. Lots of weapon systems still have pumps in one form or another

Mike Saul

Definitely the end up of a bayonet man myself, but appreciate that others may not share my view

Geoff

Have we even cut the first steel for a T31 yet ?

Talk about dragging on. And on. And on…

RobW

No, slated for later this year. Nothing more specific announced.

In service date is 2027 so plenty of time.

Julian

This is taking the p*ss, or at least that second to last pump on the list is 🙂

The Urea is most probably used in the ships exhaust system to reduce emissions. It’s the main constituent of the Adblue that we put in our diesel cars.

Thanks for the updated picture, at least one regular commentator should be pleased.

Cheers

Hamworthy are pretty much the go to pump maker for the RN. A lot of the old obsolete kit on T23 has been replaced with Hamworthy gear.
They are a pig if you need to align the motor to the pump though because of a defect of motor/pump replacement.
Laser alignment is usually used .
High speed rotation of the electric motor and misalignment on a heavy pump with lots of rotational inertia are not good for vibration and wear hence the exacting alignment requirements

Sceptical Richard

Presumably in an ASW ship, quiet pumps are a must

Andrew

Remember the days when we had a navy before it was cut to the bone

Gunbuster

On any ship quiet pumps are a must. Vibration causes noise that travels through the steel and can lead to a weird hum being transmitted by bulkheads well away from the pump.
in addition vibration leads to wear and ultimately defects and failure of the pump.

Also the T31 design being a large hull will have added flexibility allowing Babcock to substitute equipment specified on the Danish design. Will also mean upgrading later will be easier, allowing COTS replacements.

Seems I’m behind the times 🙂

Hamworthy don’t make pumps in the UK anymore. They will all be manufactured in Singapore. Great British name though (touch of sarcasm).

What has happened to my comment? It was here – supposedly under review – and now it’s gone!!!

John Mulley

It’s back. Maybe I should have gone to specsavers.
