Gibdock performs invasive species action on the Normand Reach

A surge in offshore vessel repair and maintenance work at Gibdock yard in Gibraltar has included a special project for returning customer Solstad, to ensure that Normand Reach meets the exacting hull cleanliness standards set by Australia’s National Biofouling Management Guidelines For Commercial Vessels.

The 120.85m-length Solstad CSV (construction support vessel) entered the yard for a special wash and brush-up on its way to Western Australia, where it has been reported as due to enter charter in the coming weeks to work in the Ichthys gas field development project.

Solstad is a regular Gibdock customer, but this is the first time that the 2014-built Normand Reach has been in the yard. It spent an 11-day period in Drydock No.2 for hull washing, blasting and antifouling coating, routine dry-docking works and final tasks carried out afloat.

Australian guidelines covering invasive species are among the most demanding in the world. Over and above regular hull-cleaning work and propeller polishing, Australian inspections focus on niche areas where biofouling can accumulate, including the rudder hinge, sea chest, bilge keel and bow thruster, and any associated grates.

“The internal surfaces of sea chests, for example, need to be painted with antifouling coatings that are suitable for the flow conditions of seawater through the chest,” said Gibdock ship manager Filip Tsankov. “These standards demand deep cleaning and close attention to detail.”

Gibdock has performed hull cleaning work in line with Australian expectations on several occasions, Tsankov added. Gibdock also undertook some special fabrication work as part of the job, with new plating installed to reinforce the vessel’s bridge and main deck protection against the threat of piracy.
