Lerwick Ocean Kinetics’ marine engineering company plays a key role in the development of the Port of Aberdeen


Lerwick-based marine engineering firm Ocean Kinetics is playing a key role in the £ 350million expansion of the Port of Aberdeen.

The company also has a base in Granite City and its teams are working on the project which is the largest ongoing maritime infrastructure project in the UK.

Ocean Kinetics’ role is to tow and position concrete structures called caissons. They were towed from Invergordon floating storage in the Cromarty estuary to Nigg Bay in Aberdeen.

Once positioned, they are weighted with sea water and filled with rock before being covered with concrete. They will form the new quay of the southern port.

General Manager John Henderson said, “Our job is to prepare the remaining boxes for towing, provide assistance during towing, and then place the boxes and ballast them to the seabed in the correct position.

“The first two have now been delivered and are in place – each caisson is approximately 51 meters long, 12 meters wide, 16 meters deep and weighs 5,500 tonnes – these two caissons are the last units of the Castlegate at 540 meters in length. long, facing north. Dock.

“The first two caissons were successfully towed from Invergordon to the new port, hoisted in and ballasted on the seabed with the required precision. Now let’s move on to the caissons for East Dunnottar Quays.

“This is a challenging and highly skilled job that requires a great deal of experience and expertise, which is delivered reliably, thanks to our team led by the Director of Marine Projects in Aberdeen, Michael Fox, who works with Aberdeen Harbor for many years.

“We are very proud to play our part in this program which, when completed, will support the international shipping industry and other major sectors including renewable energy and decommissioning. “
