T1200 Completes North Sea Project

T1200 Completes North Sea Project

Helix Energy Solutions Group’s new T1200 burial and trenching unit is quickly establishing a positive track record following the completion of an oil and gas project in the North Sea. The T1200 features a 1,200hp jet trenching spread, capable of burying product in water depths to 3,000m (10,000ft).

T1200 was deployed to bury a 14km long (8.7 mile), 10 inch export pipeline that included a 3 inch piggyback methanol line. The project specialization called for the line to be buried 2m (6.5ft) deep, with one meter of covering fill. The subsea trenching unit’s water jetting system trenched and simultaneously buried the pipeline under 1.4m (4.5ft) of sand in a continuous run that took just 48 hours.

The successful project is the T1200’s first oil and gas operation, and proves the versatility of the asset which has also been deployed to trench and bury high voltage undersea cables used to transport electricity from offshore wind farms to onshore power stations.

The T1200, operated by Helix ESG’s robotics subsidiary, Canyon Offshore, performed its first trenching job in early July 2012 at the Sheringham Shoal offshore wind farm trenching and burying an approximately 700m (2,300ft) long power cable between the wind turbines. Out of the 80 sections required in the field, the T1200 trenched and buried 37.

The T1200 was built in the UK by Forum Energy Technologies’ Perry Slingsby Systems ROV brand. The T1200’s design was based around the time proven T750 trencher( also owned and operated by Canyon Offshore) but has over 50 percent greater power and the capacity to trench larger diameter products (36 inches) to burial depths of 3m (10ft) depending on soil strength.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
