High-tech bridge systems for SAL’s innovative newbuilds

Seawork 11th - 13th June 2024	Speed@Seawork 10th June 2024	Commercial Marine Network Conferences

The 25th edition of Europe’s largest commercial marine and workboat exhibition, provides businesses the opportunity to showcase their services, equipment, vessels and supplies to an international audience.	Speed@Seawork on Monday 10 June in Cowes offers a sector specific event that showcases fast vessels operating at high speed for security interventions and Search & Rescue.	The Commercial Marine Network, in partnership with Seawork and Maritime Journal, introduce Series 3 of ‘Get set for Workboat 2050’. An online conference series of expert panels navigating the waters of decarbonisation compliance and looking at practical applications across the workboat industry.

A series of vessels under construction for SAL Heavy Lift will feature a networked suite of navigation, steering and heading management systems from Sperry Marine

The VisionMaster Net bridge, NAVIGAT gyrocompass and NAVIPILOT 4500N autopilot will equip the four vessels being built at WuHu shipyard in China.

“This agreement demonstrates Sperry Marine’s ability to support the primary goals of SAL’s newbuilding programme, providing advanced solutions for safety of navigation as well as greater vessel efficiency and fuel savings,” said James Collett, managing director, Sperry Marine.

“Equipping these highly-specialised ships calls for a unique blend of technical expertise and close co-ordination between SAL and Sperry’s global teams.”

Connected navigation

Sperry Marine’s VM Net bridge system provides connected navigation and can be supported remotely, reducing the requirement for in-person service calls. VM Net is designed for simplified deployment and increased system availability, creating the foundation for ‘big data’ on the vessel to improve operational efficiency while reducing through-life costs.

The NAVIGAT 3500 fibre optic gyrocompass provides highly accurate pitch/heave information which is particularly important for safe operations under loaded conditions.

Sperry’s NAVIGAT family of compasses provide superior heading measurement in all kinds of dynamic conditions with compatibility to Sperry Marine CompassNet, the networked heading management system.

NAVIGAT 3500 can also contribute to fuel efficiency gains, supporting course optimisation using Sperry’s NAVIPILOT 4500N autopilot, which reduces rudder drag, further improving the performance of the vessels.

Part of the NAVIPILOT series of autopilot systems, NAVIPILOT 4500N is designed to deliver improved course-keeping with reduced fuel consumption and lower workload on the bridge.

HAL’s new ORCA class vessels will feature methanol-ready propulsion systems and zero emission port operations thanks to ‘cold-ironing’ connections to shoreside electricity. The vessels feature powerful, fast and fully electric cranes with 1,600 tonnes of lifting capacity.
