Ancillary equipment Steel Climber is
ready to go The SteelClimber Mk 2 is a hydraulically steered and driven lift and adheres magnetically to steel structures with considerable force. A patented use of permanent magnets through two flexible belts enables the SteelClimber to operate above or below water and to travel at up to 30m per minute at any altitude. Tis makes it an ideal vehicle for a wide range of tasks such as hull cleaning and thickness measurement. Its developers; Miko Marine AS and Bratberg Producter AS are now inviting approaches from organisations with payloads that the SteelClimber can deploy for them. It is capable of carrying a payload of up to 200kg
and the SteelClimber can be deployed by a crane and submerged before it can function. Te unit can simply be attached to the freeboard of a hull, inspected to check that its payload is fully functional and then driven down the side of the ship and into the water. Te design of the belt drive enables it to negotiate curved surfaces, to pass over marine growth with ease and to access all of a ship’s submerged surfaces. Powerful magnetic rollers behind the belts each have
an adhesion force of 40Kg each. Normally nine magnetic rollers are used and even through the heavy duty 2mm thick belt an adhesive holding force of up to 360kg can be measured. Tis gives the device its exceptional load carrying capability and ensures that it is unaffected by currents or vessel movement. When it is being deployed out of water the
SteelClimber offers a practical means of undertaking cleaning, inspection or maintenance tasks in otherwise inaccessible tanks, holds or superstructure. Te simplicity and reliability of the hydraulic drive and steering system is also seen as a major benefit that will enable high value payloads to be deployed with confidence.

Ancillary equipment Eniram DTA 14
Roll-Out on NCL Eniram Ltd. has announced the extension of the existing fleet-wide agreement with Norwegian Cruise Line (NCL) to provide its Dynamic Trimming Assistant (DTA) to include newbuild NCL cruise vessels.
Te system will now be deployed on the Norwegian
Epic and the plan is to deploy the Eniram DTA to all future NCL cruise vessels. Following the first installation on Norwegian Jewel
in October 2008, the Eniram DTA has been rolled out to all NCL cruise vessels in operation. Te fleet-wide use has proved to bring significant savings on fuel consumption and a corresponding decrease on exhaust emissions. Te DTA dynamically retrieves and analyses data of the prevailing trim, propulsion power and the use of stabilisers. Te system combines the data with current conditions such as waves, wind and speed, and determines the optimal trim for each situation.

Ancillary equipment Final approval for
cleanballast Te International Maritime Organization (IMO) has granted the Final Approval of Active Substances to RWO’s ballast water treatment system CleanBallast. Bremen-based RWO. Te IMO has granted the Final Approval of Active
Substances to RWO’s ballast water treatment system CleanBallast at the 59th session of the IMO’s Marine Environment Protection Committee (MEPC59) on 17 July 2009. Tis final approval is one of four major steps necessary
for obtaining the full type approval certificate for ballast water treatment systems. As a first step, RWO received the basic approval of active substances from the IMO in October 2006 and subsequently finalised the land-based type approval of CleanBallast in 2007. With the newly granted Final Approval, the ongoing
shipboard type approval will be the last step required for obtaining the type approval certificate. Two of the required tests were successfully completed aboard a container vessel during recent months and the third, and last test necessary to complete the six months minimum shipboard testing period is scheduled to be carried out in late summer. RWO is hoping to be issued with the full Type Approval Certificate for its CleanBallast system by the German administration in autumn 2009.
