The operator is also keen to point out that the use of marine diesel oil (MDO) as fuel simplifies the ma- chinery and thus enhances reliabil- ity and safety. Unlike heavy fuel oil, MDO does not need to be heated to remain fluid, and this simplifies the fuel oil system: no heating sys- tems are needed for tanks, pipes etc.; the number of separators, pumps and filters is reduced; no tank insulation is required; an emer- gency system which may be needed in case of a heating system failure can be omitted; and the significant reduction in the amount of required heating means that complex thermo oil or steam systems, including ex- haust gas boilers, can be replaced by a simple hot water system. MDO is also a cleaner fuel. TT Lines esti- mates that around $1.3 million can be saved, compared with ships of the previous generation.

Other economies have been achieved by utilizing a streamlined hull, the design of which has been under development in Finland since the mid-1980s. Described as a "pram type semi-tunnel form," the im- proved lines — claimed to require around 18 percent less power — are achieved by means of a lower block coefficient and a slender forebody in combination with wide, moderately tunneled aft lines. Optimized forebody lines above the water also improve the ship's behavior at sea and reduce stresses, particularly on the bow doors. An aerodynami- cally-shaped superstructure front bulkhead also reduces air resistance in head winds, thus reducing speed loss in bad weather.

Aside from improvements in ex- haust gas emissions and fuel con- sumption, Robin Hood and sistership have other environmen- tal features such as a pre-sorting waste handling system for solid and hazardous waste — all of which is collected on board and disposed of on land — and a fully biological onboard sewage plant. All refrig- erators are CFC-free; all cables are halogen-free so as not to emit dan- gerous smoke in the event of fire; waste heat from the diesel engines is recovered wherever possible; paints used are largely water soluble; and anti-fouling is tin-free.

A futuristic approach has also been adopted with regard to safety factors, particularly damage stabil- ity in the event of grounding or collision, more than satisfying

SOLAS 90 regulations (Stab 90

Rules). Double skin has even been incorporated above the bulkhead deck although not a legal require- ment. Further improvements have been achieved by two longitudinal bulkheads on the main deck which also contain ventilation ducts for the lower hold. These ensure that, in the unlikely event of cargo shift- ing, the effects are minimal and stability is enhanced.

The newest fire safety regula- tions covering improved insulation, dimensioning and arrangement of escape routes and stairs, fire alarms and sprinklers, and low location lighting, have also been followed.

Advanced navigation electronics with anti-collision radars are found on the bridge, where highly auto- mated engine control also takes place. The integrated automation system for control and monitoring of ship operation technology is based largely on the Damatic XD system supplied by Lyngs0 Marine, a sub- sidiary of STN Atlas Elektronik.

Acting as a junction point for data coming from the areas of ship con- trol, safety and cargo, it enables the navigator to monitor all ship opera- tion equipment from the bridge.

Modular in design, the Damatic XD has numerous computer stations for fail-safe operation, and is powered by a Geapas automatic power sup- ply system.

Atlas has also supplied an inte- grated navigation and command
