Feature 2 | MEDITERRANEAN iversity defines Naval Rocha’s year
Portugal’s Naval Rocha shipyard enjoyed a positive first half of 2018, delivering a series of projects on a wide range of vessel types in its three drydocks, as well as alongside
a wide variety of repair and conversion projects this year. Visitors to the shipyard have included container vessels, cruise liners, passenger ships, survey vessels, naval ships, anchor handing tugs, supply vessels and dredgers. “Naval Rocha is a unique, modern
N
shipyard,” says commercial director Sergio Rodrigues. “We are located in a prime position in the centre of a European capital city which enjoys 300 days of sunshine a year. This provides ideal ship repair and conversion conditions.” One of the yard’s first projects in 2018
involved containership Monte da Guia, owned by Transinsular and operated by S&C Ship Management. Tis 27 day project required 40tonnes of steelwork in various areas, including the ballast tanks and the cargo hold. Mechanical work was carried out in the engine room, while maintenance work was undertaken to the vessel’s propeller shaſts, rudders and cranes. Other commercial vessel contracts over
the first six months of 2018 included the Nox, an oil and chemical tanker operated by Greece’s World Carrier Corporation, and the Nordanhav, a self-unloading cargo carrier, owned by Citadel Shipping in Sweden and operated by Tunbalogen Ship Management. Nox was in the yard for nine days and the scope of work included an intermediate drydock survey, washing, painting and the overhaul of its sea valves. Meanwhile, the Nordanhav docked alongside at Naval Rocha for 17 days, undergoing extensive maintenance including electrical, hydraulic and mechanical work, with additional repairs to the conveyor belt and crane system. Another area of strong growth for Naval
Rocha shipyard is the livestock carrier market, a business linked to Portugal’s growing exports to the Middle East. A recent repair contract in this market involved the

Alondra, owned by Denmark’s Corral Line. Te yard has also saw significant activity in the passenger shipping sector, with notable visitors including Star Flyer, a sailing vessel operated by Monaco-based Star Clippers, Corinthian, a polar expedition ship for Grand Circle Cruise Line and Astoria, a cruise vessel operated by Global Cruise Lines. Star Flyer received extensive steel work
to its ballast water and sewage tanks, mechanical work, new piping, and blasting and painting during an intensive 15 day stay at the yard. Corinthian underwent wet dock repairs and is scheduled to return for the installation of a new sewage treatment system later this year, while its sistership, Clio, is scheduled to drydock at Naval Rocha towards the end of 2018. “Te arrival of Astoria marked one of
the largest vessels we have managed in our docks, at 160m length with a beam of 21m,” says Rodrigues. “Te 23 day project in Dock 1 involved mechanical work, small amounts of steel fabrication, refurbishment to cabin areas, the overhaul of life-saving equipment, along with general washing, painting and certificate clearance.” Te yard has also worked on a series of
research survey vessels, including Ocean Diversity, managed by Marine Projects in Rotterdam, and NRP Almirante Gago Coutinho, operated by the Portuguese
Navy’s Instituto Hidrográfico. Ocean Diversity’s 40 day drydock involved maintenance to its underwater systems, hull protection, steel modifications on deck as well as repairs to its hydraulics, machinery and piping. NRP Almirante Gago Coutinho, meanwhile, underwent general servicing and propeller repairs. A second research vessel operated by Instituto Hidrográfico, Noruega, is scheduled to drydock later in the year for echo sounding modifications. A further notable project carried in
the first half of this year at the Lisbon yard involved the LPG carrier, St Vincent, operated by Epic Ship Management. Tis 16 day project required the supply of 18tonnes of nitrogen for the ‘gassing up’ process. In addition various mechanical and electrical repairs and upgrades were delivered to the vessel’s propellers, cargo tanks, motors, turbochargers, engines and boilers. “Naval Rocha is now aiming to build
on the momentum of recent months and target projects in specific areas where we have a strong track record and expertise,” says Rodrigues. “Tis includes the LPG market where we have delivered an average of three projects each year for the last four years. Te oil, chemical and livestock carrier markets are also firmly on our radar.” SR
