|The vessel will be designed by BMT Nigel Gee Ltd., world-reputable commercial & defense catamaran design and engineer transferring company. The hull form is well proven and will be hard-chined catamaran and can offer excellent stability with seakeeping quality and manoeverability to cater heavy-duty operations in rough sea conditions of Saudi Arabia. By using this well proven hull form we have traded some potential top end speed for a better level of sea-keeping and a softer ride with upgrade of operation experience drawn from many of the proven hulls that have been operated world-widely as multi-functional platform to cater the most rough sea condition of its type of vessel. This means making life more comfortable for the crew and allowing the vessel to maintain performance over a wider range of sea conditions. The vessel shall have the capability to operate upto 100 NM from the coast upto sea state 3 on hydrographic tasks and upto sea state 5 for survivability The vessel shall be multi-utility to include: a. Hydrographic survey (including coral reefs surveys). B. Marine Sciences surveys. C. Marine Geophysical survey. D. Deployment of ROV, Towed systems, Oceanographic profiling, etc. E. Search and Rescue. F. Towing of another small vessels in emergency.
