Auxiliary equipment Cathelco Brazilian
venture Cathelco has set up a joint venture with Workship do Brasil, the Rio de Janeiro-based marine equipment supplier, which will now be known as Cathelco Brasil. The venture will oversee the kitting out of 10 x 157,000dwt crude carriers on order for Transpetro with Cathelco Jotun marine pipework anti-fouling equipment in conjunction with Impressed Current Cathode Protection (ICCP) and hull corrosion protection systems. Te ICCP equipment will consist of a 150amp forward
system using elliptical anodes and a 600amp aſt system using linear loop anodes which emit a powerful current from a relatively small surface area. The pipework anti-fouling system will protect two sea-chests on each ship using copper and aluminium anodes connected to a control panel. In December, Cathelco Brasil won an order to supply
a series of five 2700dwt container vessels with ICCP equipment. Te ships are being constructed at the Eisa Istaleiro Ilha yard in Rio for Log-In Logistic Intermodal and will each have 350amp forward and aſt systems.

Auxiliary equipment Ecospec launches
CSNOx Ecospec Global Technology Pte Ltd has launched CSNOx, a new system designed to reduce nitrogen oxide sulphur dioxide, carbon dioxide and particulate matter emissions from ships in a single process system. Te scrubbing process is claimed as being achieved at a net carbon credit gain without any net increase in CO2
to the atmosphere or
acidifying of the ocean. Tere are also no other secondary pollutants discharged into the sea, according to Ecospec. Due to its compact design CSNOx, is easy to install on ships. Drawing from its core technology in water and oil
82.2% and 74.4% efficiency for scrubbing SO2 CO2
respectively, according to Ecospec. 14
treatment in its development, Ecospec has tested CSNOx onboard an ocean-going supertanker, jointly with ABS, and a tanker shipping company. Te results of the test show that the device has 92.9%, , NOx and
The CSNOx technology developed by Ecospec.

Auxiliary equipment MiKO gets the drift
Miko Marine AS, of Oslo, has begun work on the ShipArrestor project following the signing of a contract with the European Union in October 2008. Te two year project is aimed at developing a technique
that can enable a tow line to be attached to an unmanned vessel and used to reduce the driſt of ships that have experienced a loss of power, to reduce the chances of grounding and the pollution. Miko Marine holds the patent for the ShipArrestor
principle, which is designed to enable a conventional Search and Rescue helicopter to deploy a tow line around the winch gear on the foredeck of an abandoned vessel. Te helicopter can then lay the line upwind, and release it attached to a sea anchor. Te effect upon the ship will be almost immediate so that it is turned into the wind with its driſt speed reduced by 50%. A tug can then pick-up the the sea anchor and ShipArrestor line and effect a rescue. If a ship is already driſting close to shore, the use of a sea anchor may not be appropriate, in which case the helicopter may deliver the line directly to the first available rescue tug. Te concept of the sea anchor is already well known to
seafarers but, until now, its use has been restricted to smaller vessels. Part of the project will include the mathematical modelling needed to identify the size of sea anchors needed for ships of different tonnages.
