This post highlights some of the exciting marine, offshore and subsea engineering currently going on in the North East…….

Over the weekend I met up with a good friend of mine, Tom, who also graduated from Newcastle as a naval architect and now heads up technical sales for IHC Engineering Business. He has a pretty diverse job – ranging from concept ship design leading to contract through to marketing the Hi-Traq subsea plough to customers around the world (he is flying off to Rio de Janeiro today!).

IHC have been expanding their assembly yard in Port of Blyth, and Tom pointed me to an excellent video up on youtube which highlights some of the goings-on in the port. There’s not much commentary so I scribbled down a few extra nuggets of information which I thought were well worth sharing. The video is embedded at the bottom of this post.

0:06: this is the south harbour – spot Royal Northumberland Yacht Club and a busy quayside. As the camera pans past you can spot the marine propulsion lab building (its the building that looks a bit like an upturned keel).

0:28: The ship is the Maersk Connector, built by Damen in the Netherlands and currently chartered by DeepOcean – who operate 14 vessels for subsea support. They have a big presence in Blyth port and also work alongside several other companies including IHC EB (as you will see later on). Currently Maersk Connector is regularly sailing past our lab windows!

0:43: This shot shows battleship wharf and the up-river part of the port. Most of the larger buildings are the Offshore Renewable Catapult (ORE) – which is the UK test facility for wind/tide/wave devices (at least 3 graduates from our school now work there).

0:49: Up-river there is still plenty of space for more industry – and more is coming!

0:52: A shot of the marine propulsion lab building. Its great to be right in the middle of the industry. The warehouse just behind is full of DeepOcean’s equipment including ROVs, trenchers and other big bits of equipment.

0:54: This section of the video focuses on IHC. The white framed device is a subsea plough.

1:01: The huge grey structure is IHCs J-Lay tower. I’ve added another youtube link at the bottom showing the load-out of the tower onto a barge. The tower is now sticking up out of Blyth like a giant finger. The principal engineer for the J-Lay project is a naval architect from Newcastle university who graduated in 2005. I can count 7 graduates from marine technology currently working at IHC – there are probably more I’ve missed.

1:04: The renewables sector is key for Blyth. The latest round of offshore wind developments in the north sea needs massive shore based engineering support. Exciting times!

1:09: A shot of the IHC workshop. The A-frame in the centre is on bogies ready for load-out onto the Maersk Connector.

1:25: The A-frame is installed at the stern for deployment of the plough shown at 0:54. The system is commonly known as a LARS (Launch and Recovery System).  The model ROV in our hydrodynamics labs was used to better predict the loads experienced by a LARS system such as this – although that research was for SMD based in North Tyneside.

1:48: The port also functions for conventional cargo ships including coaster container ships and bulk carriers.

2:09: Spot the Princess Royal research vessel, which is moored just next to the marine propulsion lab along with a purpose built shore station for research and teaching.

2:16: The large circular framework in the midship area of the deck is known as a carousel and you can probably guess what it is used for!

Here is the complete video on youtube:

And here is a video to give you an idea just how huge the J-Lay tower is:

Axiom are a British company who manufacture innovative propellers for yachts and narrowboats. They have an excellent video posted up on YouTube which was produced in the Emerson Cavitation Tunnel in 2012 by Rod Sampson, Mehmet Atlar and George Politis. This is an excellent example of an open water propeller test, showing increased extent and interaction of cavitation as the advance coefficient, J, is reduced (i.e. the propeller rpm is increased).

What types of cavitation can you spot?

I plan to post further about some of the experimental techniques seen in videos such as this – watch this space!

A few snippets can be seen here:

The complete video from Axiom is here:

NB: Ignore the comments “below the line” – some are bad science!

Serkan posted up a great summary of some significant work undertaken in the Emerson Cavitation Tunnel on our internal engineering school bulletin:

We have some exciting news to share about an innovative ship steering system known as a Gate Rudder (GR), invented by Prof Noriyuki Sasaki, a visiting professor at Newcastle University. Apart from functioning as an innovative steering system, the GR is an energy saving device that reduces fuel consumption as well as noise and vibration. A team of researchers in the marine group have developed and tested this unconventional rudder since 2015 in the Emerson Cavitation Tunnel. Furthermore, a dedicated manoeuvring software has been written and employed during the development process.

The Gate Rudder system has recently been installed on a vessel in Japan. During manoeuvring and power-speed trials, the vessel showed impressive performance, with 14% power savings compared with a sister ship equipped with a conventional rudder. We will be involved in full-scale sea trials taking place in March 2018 in Japan.

The video below shows the gate rudder in action

The Port of Blyth is really buzzing right now: regular ship arrivals, thriving marine, offshore and subsea engineering firms (including IHC, Osbit and DeepOcean), the Offshore Renewable Energy Catapult…..and now Newcastle University!

Today I arrived early to work and was perfectly timed to see DeepOcean’s Havila Phoenix sailing into berth on the North Pier. Ten minutes of freezing cold movie making, plus a handy google auto-video, resulted in a nice little montage – see the instagram post here:

As a bonus the EDT Jane with an Ulstein X-Bow is also in port. Two ships for the price of one! If you squint you can also see the Maersk Connector and the IHC J-Lay tower further up the river.

Both the Jane and Havila Phoenix are offshore support vessel used for all sorts of subsea operations. For the naval architects and offshore engineering students I recommend spotting the equipment carried – ROVs, A-Frames, trenching machines, carousels for pipelay (although not at the moment)…….the list goes on. The “exam-question” – what do they do?

The exciting part of being located in Port of Blyth is that the engineering firms next door are designing, fabricating and installing these complex pieces of offshore equipment. They are also big employers of our students. Just from memory I have counted over 10 graduates who headed to IHC, Osbit and DeepOcean over the last 3 years – and there will be plenty of people I missed. Not bad for a graduating cohort of about 60!

 

And before you ask – I am working on arranging student visits to get on-board……
