Safe mooring advisory services for compliance and risk management

We assist you in benefiting from safer and compliant mooring operations.

Mooring operations continue to pose safety risks for mooring crew and shore personnel. To mitigate this risk, the IMO and class societies are continuously updating regulations and guidelines.

We help you review and verify the effectiveness of your vessels’ mooring system design as well as on-board mooring practices. We also provide support on vetting compliance and preparedness, and, most importantly, on safer mooring operations.

From 1 January 2024, the following guidelines will enter into force:

1. Shipboard towing and mooring equipment (MSC.1/Circ.1175/Rev.1)
2. Design of mooring arrangements and the selection of appropriate mooring equipment and fittings (MSC.1/Circ.1619) 
3. Inspection and maintenance of mooring equipment, including lines (MSC.1/Circ.1620) 

The new requirements will apply to new cargo and passenger ships constructed on or after 1 January 2024. In addition, the inspection and maintenance of mooring equipment will apply retroactively to all ships. 

Our experts at DNV can assist with safe mooring

• Inspection and maintenance plan – review and improve the plan and recordkeeping for the inspection and maintenance of mooring equipment 
• Mooring Line Management Plan – establish a regime for inspection, maintenance and replacement of mooring equipment and mooring lines
• Ship design MBL (MBLSD) – perform system design review and mooring calculations (when necessary) to determine Ship design MBL (MBLSD), especially for vessels where the original design standard is unclear 
• Mooring risk management – following the design and operational review, identify mooring risks and plan mitigation measures 
• Site specific mooring analysis – calculate mooring load, environmental limit for specific mooring terminal / quay, perform ship-terminal compatibility check, suggest on operational measures to be considered for adverse weather conditions.

At DNV, we have experts in mooring operations providing insights into:

• Relevant regulations and guidelines 
• The combination of risk, human factors and effetive operations
• Best practice for mooring operations 
• Fomalizing mooring line management based on manufacturers’ guidelines and operational experience
