Tanker operators face a number of challenges when it comes to complying with the OCIMF MEG4 (Mooring Equipment Guidelines) which came into force in May 2018. OCIMF MEG4 replaced MEG3 which was published in 2008.

These guidelines are designed to promote safe and responsible operations in the maritime industry, but they can be difficult to implement in practice. Here are some of the key challenges faced by tanker operators when it comes to OCIMF MEG4 compliance:

Determination of SDMBL:

Equipment Selection: One of the primary challenges faced by tanker operators is selecting the right mooring equipment, especially Mooring Ropes to meet MEG4 standards. This requires a thorough understanding of the different types of equipment, Mooring Ropes available, and their respective advantages and limitations.

Equipment Maintenance: Another challenge is maintaining mooring equipment to ensure that it remains safe and effective. This requires regular inspection, testing, and maintenance, as well as proper documentation and record-keeping. Winch Brake Testing forms a key part of the maintenance procedures. Winch Design Brake Holding Capacity is fixed however rendering capacity may be reduced. Equipment like Mooring Chocks and Mooring Fairleads are an Integral part of the vessel mooring system and shall be a part of vessel PMS.

 Varying Standards: Another challenge is to comply with various stakeholders with limited onboard resources. For example, even after complying with OCIMF MEG4 the Local ports may ask for a different mooring arrangement or a different kind of Mooring Hawsers. Even worse different Oil Majors may dictate different standards for Mooring Hawsers.

Crew Training: Ensuring that crew members are properly trained to use mooring equipment in compliance with MEG4 standards can be a significant challenge. This requires ongoing training and education to ensure that crew members have the necessary skills and knowledge to operate equipment safely and effectively. The crew shall be thoroughly familiarised with Winch Brake Testing as well.

Compliance Documentation: Another challenge is ensuring that all necessary documentation such as MSMP & LMP is maintained and up-to-date to demonstrate compliance with MEG4. This can be a time-consuming and resource-intensive process, particularly for larger tanker operators.

MSMP stands for Mooring System Management Plan

LMP stands for Line Management Plan

Cost: Finally, complying with MEG4 can be costly, particularly for smaller tanker operators who may not have the same resources as larger companies. This can include the cost of new equipment, cost of mooring ropes, of maintenance and inspection, crew training, and compliance documentation.

 In order to overcome these challenges, tanker operators must be committed to ongoing education and training, as well as investing in the necessary resources and equipment to ensure compliance with MEG4. This will not only help to ensure safe and responsible operations but also improve efficiency and protect the environment.

Manager – Tanker Operations, Fleet Management India Pvt. Ltd.

“‘Broadside Marine’ have proficiently cracked the code on calculating ‘SDMBL’ basis provided information & environmental forces in line with MEG4 guidelines. In addition to being verified by LR (for their environmental forces calculation program), I must mention teams prompt service in delivering MSMP/LMP plans and in-depth knowledge on subject.”

Marine Manager, Synergy Navis Marine Pvt. Ltd.

“‘Broadside Marine’ has assisted us well for preparation of Vessel specific MSMP/LMP in line with MEG4. Broadside has also provided expert advisories when required in risk mitigation in several instances where required for vessels where full compliance with the MEG4 requirements was not immediately possible.”
