Restrictions on supply chains and international travel due to the Covid-19 outbreak have serious implications for the maritime industry, Allianz has warned in a new report.
Although the threat from the perils ships usually encounter at sea may have reduced in many cases due to an increasing number of vessels waiting at anchorage or being in lay-up, other risk challenges have replaced them, according to Safety of Maritime Assets – Tugged By A Pandemic from Allianz Global Corporate & Specialty (AGCS).
“The increasing disruption and economic pressures caused by the pandemic also has serious risk management implications for the maritime community and insurers alike,” commented Captain Rahul Khanna, global head of marine risk consulting at AGCS.
If lay-up of vessels is not properly managed, including regular maintenance, problems can materialise when the ship is ready to sail again, the report explains.
Relieving crew has become more challenging due to travel restrictions, meaning more fatigued seafarers—one of the main causes of human error on board. Delays in the servicing and inspections of vessels and emergency equipment can result in any problems remaining undetected, while supply chain disruption means oils and consumables can take longer to arrive, which can result in machinery damage if incorrect alternatives are used.
At the same time, an increase in the use of remote pilots—to protect seafarers from the risk of infection—can also have an impact on safe vessel navigation.
Although ships remain active through the Covid-19 outbreak, many vessels have been affected, leading to a number lying idle.
A vessel is considered to be on lay-up when it is taken out of service and is anchored at a fixed location for a considerable period of time without undertaking any commercial activities
In a so-called warm lay-up, vessels still have crew on board and can be ready to return to sailing relatively quickly. In a cold lay-up, a skeleton crew is retained for tasks such as maintenance, but most systems are shut down.
Reactivating the vessel can take time, requiring extensive testing to ensure it is safe, and can be expensive, costing up to millions of dollars in worst cases.
Khanna explained: “An unplanned lay-up can result in a prolonged recommissioning exercise that can last for months, even requiring docking. Comprehensive plans including risk assessments covering storage and lay-up are crucial for ensuring the safety of the vessel during the downtime and its subsequent return to service.”
Allianz is encouraging ship owners to use guidance documents and checklists provided by classification societies when preparing this plan.
The lay-up plan should present a clear picture of risks specific to the location and the type of vessel, such as exposure to storms, for example—there have already been reports of a considerable number of large cruise ships being temporarily laid up around the US East Coast, with the onset of the hurricane season in the North Atlantic creating potential risks for these vessels if they can’t be moved out of harm’s way quickly.
Maintenance of main machinery and nautical equipment, fire-fighting arrangements and tug availability in a contingency should also be among the areas of focus in the plan, according to the Allianz report.
Elsewhere, travel restrictions imposed due to the pandemic have made it difficult to effect crew-change on vessels.
Border closures have limited options for repatriation and, in many cases, crews have continued working on board for months longer than usual. Longer tours of duty, coupled with concern for families at home, can cause physical and mental fatigue among seafarers. It is estimated that 75% to 96% of marine incidents can involve human error and fatigue is one of the major underlying causes.
“Adjustments in work and rest hours offer effective fatigue management,” commented Captain Nitin Chopra, senior marine risk consultant at AGCS. “Hiring from a pool of locally-available seafarers may be an option in some cases.”
Classification societies are also facing difficulties in arranging attendance for scheduled surveys, which is affecting the validity of classification and statutory certification of vessels.
The servicing of critical equipment on some vessels may not take place at the scheduled interval as service engineers are unable to attend. Shortage of workforce and implementation of social distancing measures in shipyards is causing delays. It is anticipated that the number of port state control inspections may reduce owing to the restrictions in place and this may lead to unsafe practices and conditions on board going undetected.
Chopra said: “Risks arising from delays in the servicing of emergency equipment (for example, fire-fighting appliances) will require implementation of additional control measures.”
