Light diving craft design
Norway’s Hukkelberg Boats and Denmark’s Safe Air Diving have joined forces to create an advanced Nitrox light diving craft.
With special focus on safety, ergonomics and efficiency, the new design is a mobile diving platform that sets a new standard for surface supplied diving in the offshore sector. This diving vessel represents the most advanced tool for Nitrox LDC diving in its field, and is the result of years of experience and collaboration with the diving industry. In addition to powerful twin waterjet propulsion allowing speeds in excess of 30 knots, the 12.7 metre boat also features:
* 166 litres of on board breathing gas (Nitrox), in composite bottles
* Digital display of bailout pressure for all three divers on supervisors control panel
* Digital depth displays for easy readout on supervisor’s console
* Integrated diver heating system, to increase diver comfort and safety in cold operations
* High resolution digital helmet cameras for excellent video quality
* High capacity UPS for increased running time and safety factor in case of power failure
* Redundant power supply with both on board generator and inverter
* Tender station on aft deck with audio and 15” colour display controlled by supervisor
An optional digital diver monitoring system (DMS) will be able to log all data from the diving system (including bailout pressure), improving post operation analysis and incidence investigation. Data and video may also be made available off-site through live streaming functionality, reducing the number of people required on board the vessel during operation, enabling direct communication with off-site expert collaborators.
Norwegian boat builder Hukkelberg Boats has over the last 25 years delivered around 200 high speed work boats to the global offshore energy market. Most of these have been daughter craft type vessels, used both as a rescue vessels and for various work applications around offshore oil and gas installations. Through compliance to IMO/SOLAS mandated requirements like drop- and side impact testing, Hukkelberg developed a rock solid hull design, built to withstand years of professional use.
Over the years several diving operators have converted existing Hukkelberg boats to diving vessels. In 2007 Hukkelberg made the first boat specifically designed for diving. It was fitted with a two diver AIR spread and became the first Hukkelberg LDC light diving craft.
Since then Hukkelberg has had a very close collaboration the diving industry. Gradually, they have developed their boat designs and made improvements based on experience and feedback from divers, supervisors and operators with hands on experience using Hukkelberg equipment.
In 2015, rather than retrofitting diving equipment onto existing boats, Hukkelberg and Safe Air started integrating the diving systems into the design of the boat from the start. This lead to a shift in focus for the design and manufacturing of LDCs – how to make the best, safest and most efficient workplace for divers and supervisors.
