New Guidance On Managing Blackout Risks On Passenger Ships
With power outage occurrences on cruise liner rising, DNV has actually developed a brand-new advice entitled ‘Managing the risk of blackouts’ which attends to the primary reasons and also connected threats, while supplying referrals and also finest methods on exactly how to prevent them and also decrease the possibility of their event.
In 2019 there were 12 reported power-loss occasions on cruise liner that led to complete or partial power outage while en route or manoeuvring– up from 4 occasions in 2018. Although most of occurrences take place in open water with very little repercussions, they stand for a significant mishap danger and also, in particular scenarios, lead to loss of propulsion which might posture a brewing risk to the ship, its travelers and also staff.
While over the last few years there has actually been a great deal of concentrate on sustainability aspects and also expense conserving procedures, DNV advises proprietors and also drivers not to forget the safety and security component.
“Factors such as new fuels, change of speed and other measures to remain compliant with EEXI and CII regulations are high on ship owners’ agendas. We also see a considerable focus on keeping opex and capex costs in check after two years with reduced revenue. While dealing with all these challenges we urge ship owners not to lose sight of safety. By increasing awareness of what to do to avoid and manage blackouts we want to contribute positively to building trust across the sector,” claimed Hans Eivind Siewers, Segment Director for guest ships and also ro-ro at DNV Maritime.
In the brand-new paper, DNV details a step-by-step method that centres on a streamlined barrier-risk version. A streamlined ‘bow tie’ version is made use of to provide the hazards and also technical/operational obstacles that add to increasing/decreasing the possibility of power outage, and also the mitigating obstacles for sustaining healing. The paper’s five-step framework makes the info and also useful devices simple to accessibility and also carry out.
Rami Nurminen, Director Technical Assurance at Royal Caribbean Cruises, verifies that worth of the advice for cruise ship drivers: “This is a great initiative that combines design principles, technical commissioning and human factors. A holistic approach is essential to maintaining design principles throughout system development, integration and final testing – not least operator familiarisation and training of new crew members,” he claimed.
In recap, the advice paper is meant to sustain a step-change in safety and security for drivers, from obtaining a total understanding of power outage triggers, specifying safety and security passions and also wisely taking care of clashing objectives (such as decarbonization and also expense stress), to recognizing proper functional and also technological procedures to decrease danger based upon cost-benefit examinations.
The paper additionally defines the compulsory needs for power outage avoidance and also healing that give a minimal technological criterion for newbuildings, consisting of Safe Return to Port (SRtP) laws under SOLAS and also extra procedures such as DNV’s Operational Reliability (OR) course symbols, which particularly targets durability and also schedule of propulsion, guiding, electric power and also manoeuvrability.
“DNV is of course open to engaging with operators who want to leverage our operations expertise to improve their organisation and ensure their ships are optimally ready to start sailing again. This also feeds into the newbuilding equation in terms of specifications and what barriers are built into the design to minimize blackout risks,” Siewers included.
