New Safe Mooring Guideline by DNV GL


Mooring is among the most common of all maritime tasks, yet mooring operations are far from standardized, reports DNV GL on their website.

In order to ensure safe mooring involving both new and existing tonnage and equipment, standards are currently being upgraded and conventional wisdom is being revisited.

Safe mooring

Mooring operations continue to pose safety risks for mooring crew, shore personnel and property.

Mooring Equipment Guideline 4th Edition (MEG4) was introduced by OCIMF in 2018. All new tankers, gas carriers and terminals are to be designed and built using the recommendation.

Existing tankers are to consider making changes accordingly, and as a minimum, develop a Mooring System Management Plan (MSMP) and Line Management Plan (LMP). Plans are being checked during vetting inspections. Similar guidance for other ship types is expected.

Mooring failure during lay-up period can lead to a high risk of damage to marine assets. Hence it is highly recommended to make a thorough lay-up mooring plan and seek for approval from the local authority and classification society.
