Cable lay
Installation of a 3rd Export Cable on the Greater Gabbard Offshore Wind Farm

ASV Pioneer is an efficient and cost effective windfarm support vessel with experience in a range of cable laying and repair projects such as this one. Completed in the autumn of 2011 at Ferguson’s Shipyard on the Clyde the ASV Pioneer was immediately put out to work just off the coast of Suffolk. It was chartered to support the installation of a third export cable – 45 kilometres in length – from the Greater Gabbard Offshore Wind Farm to the Sizewell B Nuclear Power Station helping to bring power onshore.

The cable was laid in two sections – the first from the Wind Farm shore towards a selected location. The inshore section was pulled from the nominated substation at Sizewell B Nuclear Power Station and then laid to the offshore location where the two sections were spliced. The whole project was completed in March having been carried out over the winter months.

Specialist projects
Salvage of Costa Concordia Cruise Ship

The Costa Concordia cruise ship hit the headlines in 2012 when it sank just off the coast of Italy leaving 32 people dead. Engineers embarked on one of the largest ever maritime salvage operations supported by the ASV Pioneer. In order to complete the project a full diving spread, cementing plant and crawler crane were installed aboard the ASV Pioneer.

The salvage operation lasted 16 months and during this time we provided accommodation for divers and cementers as well as meals for the 100+ personnel working on the Costa Concordia itself.

Cable Repair
Cable Repair on the Baltic 2 Offshore Wind Farm

In January 2015 the ASV Pioneer was chartered again and this time, it was bound for German waters of the Baltic Sea to carry out a cable repair on the Baltic 2 Offshore Wind Farm. The vessel was fitted with two cranes, cable chutes, cable tensioners and a full splicing outfit.

The ASV Pioneer has proved to be extremely stable for this type of work with warranty surveyors approving work in difficult shallow water where the work would normally be halted. The eight point mooring system which was modified for the project enabled the vessel to remain very precisely on location with no excursions and the capability for minor movements to accommodate the repair and re-lay process. This allowed the project to keep on track and it was completed in the autumn of 2015.

Cable Repair
Cable Repair on the Riffgat Offshore Wind Farm

At the end of 2015, the ASV Pioneer headed to Wilhelmshaven to provide support for more cable repairs, this time on the Riffgat Offshore Wind Farm. Again the deck was installed with all the appropriate equipment required to carry out the job which included a splicing and tensioning unit as well as crawler train and trenching outfit.

The site adjacent to the island of Borkum in the German Bight was particularly challenging as the waters are relatively shallow with strong tidal currents and difficult sea states. However, work was able to continue during a wide spectrum of different sea states thanks to the ASV Pioneer’s positive mooring and stability.

Large scale accommodation
Proposed project – provide accommodation for refugees

As well as being an efficient windfarm support vessel, the ASV Pioneer has many other uses. A proposed project involved providing accommodation for up to 100 refugees on the behalf of a government agency which included recreational, medical and security spaces. For various reasons the project did not proceed but this is a great example of the flexibility of the vessel in a number of scenarios. What’s more, the large available deck space was utilised to provide additional accommodation for this proposed project which means the ASV Pioneer can be ready for similar projects in a relatively short time.

Offshore service platform

With its eight point mooring system, 1100sq.metres of high capacity deck space, and quality accommodation for around 100 personnel, the ASV Pioneer is the ideal vessel to support offshore projects in the Offshore Wind Farm, oil and gas and construction industries.

The desk space can be used for storage, workshops or other functions. With the reliable mooring system, high stability, low fuel consumption and high capacity fuel, water and sewage systems, coupled with inbuilt landing areas it is a very useful and economic solution to support offshore projects.
