In the Yard Incat Crowther has been contracted to design a trio of 42.5m Monohull Dive Support Vessels. The design is a new concept borne of the latest ideas from designer, builder and operator. The design has been developed to be a dedicated DP-2 capable Dive Support Vessel, featuring fully integrated ROV launch and recovery, dive compres- sors and decompression chamber. The vessels, currently under construction at SeaSafe Barcos Manufaturados, in Angra do Reis, Brazil, will be delivered to Sistac. The Þ rst of the three vessels, to be named Sistac Vit?ria, is due to be delivered in the Þ rst quarter of 2014. The aft deck will feature a large work- ing deck, which will house the ROV crane and reel, a pair of dive platforms and two deck cranes. Inside the main deck house are functional areas such as toilets and showers, dive shop (housing compressors and decompression cham-ber) and ROV shop. Forward of these spaces are an ofÞ ce, TV room, meeting room, mess areas and two single-berth cabins for senior per- sonnel and a designated ofÞ cer cabin. A spacious wheelhouse is located up-stairs, with forward and aft facing vessel control stations, ROV and dive control workstations. Overhead windows are Þ tted both fore and aft for high-angle visibility. Four Scania D13 main engines, each producing 410kW, will power the ves- sels. The vessels will have a service speed of 13 knots and a top speed of 15 knots. The DP-2 capability ensures the vessel can hold station in the event of a failure in any single component of the system, enhancing both safety and reli-ability.
