The drydock project which completed in January 2020 involved a broad package of work to the ultra-modern 14 streamer 3D/4D seismic vessel – Polarcus Naila.
The vessel is amongst the most environmentally advanced seismic vessels in the world with diesel-electric propulsion, high specification catalytic convertors, a double hull and advanced bilge water cleaning system.
Navalrocha Commercial Director Sergio Rodrigues said the sensitive project involved wide-ranging work.
The Polarcus Naila visited Navalrocha shipyard for a total of 33-days running through the Christmas period,” he said. “The project involved five principal partners which operate at the Navalrocha shipyard base and a series of other specialist maritime firms, delivering a variety of mechanical, hydraulic, piping, steel work, blasting and painting as well as oil, fuel and ballast tank cleaning, carpentry and welding.
“Around 350 engineers were involved in the project which required careful management of high-value survey equipment. Four mobile cranes, three yards cranes and six forklift trucks were used to manoeuvre on-board infrastructure. Engineers repaired four winches, replaced a further two and installed two new winches to boost operations. A new partnership with Cyprus-based Deme Marine also saw the delivery of robotic hydro-blasting. This service helped reduce time and manpower while ensuring zero dust contamination or damage to seismic equipment, which can occur using more traditional slurry blasting techniques.”
The news comes shortly after Navalrocha delivered its first ever BWTS project for the Paxoi bunker tanker capping off an active 12 months notching up more than 30 drydock, wet basin and pier-side projects. Recent work has involved livestock carriers, polar expedition vessels, car-ferries, tugboats, cargo-carriers, cruise ships and sailing vessels. The yard is also driving further expansion in the LPG and product carrier markets.
