DNV GL Provides Innovative and Reliable Support for Smart Navies and Maritime Authorities

DNV GL, a leading and reputed international classification society, provides classification services and technical support for navy projects at every step of the vessel’s life cycle – from the specification stage, construction phase and operational life to the decommissioning process. The organisation’s services in addition to focusing on technical, safety and quality issues, also lay emphasis on project and risk management and vessel optimisation ensuring that reliability, operability, maintainability and life-cycle cost are considered during every step of the project. For this purpose, DNV GL provides engineering expertise through their worldwide network of marine surveyors and maritime advisors, including a significant presence in Southeast Asia, Australia and New Zealand.

DNV GL works to help naval designers, naval shipyards and navies improve their safety, operational availability and future-proof themselves amid geopolitical, technological and economic change and pressures. Additionally, it has been supporting navies with the implementation of new technologies, such as alternative propulsion systems, composite materials for hull and superstructure, lithium-ion (Li-ion) batteries, ships with modular multi-role missions and unmanned autonomous vehicles. Responding to the demands of naval shipyards and navies for greater standardisation of both safety and ship-design standards, DNV GL combines its legacy Naval Rules sets into common goal-based standards for naval surface vessel and submarine safety and technical assurance. The aim is to build in more flexibility to address the varying requirements that navies have today or are likely to have in the future. Another aim is to support navies who are looking to implement technical-assurance processes. Some navies are using the so-called Naval Ship Code as a de facto standard. Others are developing their own seaworthiness management systems where elements of classification society rules might be considered and used. This means that DNV GL’s new Naval Rule set is being designed to engage with existing and future technical-assurance seaworthiness safety frameworks.

Technical Assurance Services in Australia: Australia provides a good illustration of how DNV GL’s activities in class and technical assurance for navies complement each other. The company has provided classification and certification services for the building of many high-speed ferries and government vessels there over decades. This deep experience is now combined with DNV GL’s global expertise to provide technical assurance services for the construction of twelve 80-m offshore patrol vessels (OPVs) to be built at two shipyards in the country for the Department of Defence and the Royal Australian Navy (RAN).

Boosting Navy Vessel Reliability and Availability: DNV GL has long supported navies in investigating the potential causes and long-term effects of observed structural deformations on naval vessels. In 2018, DNV GL advanced the development of new approaches and solutions to address the growing challenge of reliability and availability of naval platforms as drivers such as complex technology, automation, reduced personnel complements and skills shortages place extra demands on vessels and navies. There is a need in future to focus not only on minimum safety requirements, but also on solutions to meet minimum reliability criteria.

Life of Type Extension: Navies today are facing increasing challenges for their aging fleets. The need for system upgrades puts pressure on limited budgets and resources – not to mention long lead-times for new-build programmes – and drive the demand for alternative solutions. Life of Type Extension (LOTE) is one of the most practical approaches to move beyond the original design limitations and fulfill the needs of future duties and commitments by keeping the existing vessels longer in-service than originally planned but in a safe and reliable way. DNV GL has developed a flexible, inclusive LOTE approach, building on the in-service experience of platform systems from hundreds of naval vessels and support of new-build programs over a long period worldwide.

Hybrid and Battery Solutions for Naval Ships: DNV GL has established a full range of tools and services to assist navies to develop newbuild and retrofit hybrid and battery solutions. DNV GL has worked closely with navies over the past year on the implications of Li-ion batteries in naval applications and has adapted the Battery Rules and Battery Guidelines to naval needs. DNV GL’s offering to navies in this space include its “Battery Ready” services; type approval and classification; technical/economic analysis; risk analysis; battery service life and optimisation analysis; ship performance instrumentation, measurements and analyses; technology qualification; and hardware-in-the-loop testing of battery management systems.

Cyber Security Knowledge Transfer: Digitisation in the maritime world is taking off, with increasing cyber security risks, particularly where connectivity between IT and operational technology allows malicious hackers to exploit weaknesses to access maritime or industrial control systems. DNV GL launched its Recommended Practice DNVGL-RP-0496 Cyber security resilience management for ships and mobile offshore units in operation. It helps to prepare for an ISO 27001 certification by outlining a strategy to assess weakness under three headings: technology, processes and people. Navies have had cyber security on their radar for much longer than commercial shipping, but DNV GL can help navies to take from the experiences of the commercial shipping world and adapt proven standards and practices for naval use. A first contract has been signed in this respect for a forthcoming navy newbuilding project. DNV GL provides technical assurance and advisory services to the German, Norwegian, Australian, Dutch, Danish, South African and many other navies around the world. DNV GL is also a founding member of NCSA and INSA and a contributor to the various working groups of these institutions.
