UT 790 CD Deepwater anchor-handler

Stability with efficiency
Normally a larger beam for greater stability would imply extra hull resistance, but the UT 790 benefits from a new 23m form that has lower resistance than traditional 20 and 22m designs and combines a wave piercing bow that pierces through the water rather than riding on top of the waves.
This allows the vessel to run continuously at service speeds regardless of sea-state and eliminates slamming. At speeds of 14 knots and violent storm conditions (waves higher than 9m), tank tests show no water above forecastle deck level. In extreme wave heights, water will be visible at the forecastle long before the situation gets critical, allowing power to be reduced and the maintaining of generous safety margins.
The UT 790 CD re-thinks anchor handler layout, moving the engines further aft and locating the secondary winches low down, where the engine room would traditionally be, to help improve stability and free-up space.
The UT 790 CD has the same fibre and rope capacity operating with four secondary winches as a traditional anchor-handler has with six. The vessel has the power and capacity to handle cable, chain and rope down to 2000 metres, and fibre rope down to 3000 metres.
Another notable feature is the extra buoyancy in the cargo railings, providing further stability and safety in case of extreme heeling levels.
Locating the engine room astern also reduces engine noise and permits shorter exhaust ducting which includes a Mecmar wet exhaust system, with cooled exhaust leaving the ship at sea level.
As there are no exhaust casings the enhanced 360-degree view from the bridge significantly improves safety.
