What does Meg 4 say about the mooring equipment?
The guidance within MEG is sure to enhance the safety of mooring from the design of mooring arrangements using a Human Centred Design approach and an increased focus on the use and understanding of mooring lines and tails.
What is LDBF for mooring ropes?
Line Design Break Force
Line Design Break Force – (LDBF) This is the minimum force that a new, dry, spliced mooring line will break at when tested according to appendix B. This is for all mooring line and tail materials except those manufactured from nylon which is tested wet and spliced.
How do you secure the mooring rope to the mooring Bitts?
Securing Rope on Bitts At least three ‘figures of eight’ turns should be taken. First figure of 8 turn should be taken round the bitts. The next two turns can be ordinary criss-cross turns. Wire ropes when made fast on bits should be lashed.
What are the safety measures to be taken when handling mooring ropes?
Safety of crew during mooring operations
- Use of remote control position for operating winches (where applicable)
- Clear layout on deck prior operations.
- The use of proper personal protective equipment.
- Identification and monitoring of dangerous zones during mooring operations.
- Quick and close communication between stations.
What is MBL in mooring?
Minimum breaking load of a mooring line (MBL)
What is MEG4 compliance?
MEG4: The new standards of mooring ropes The updated MEG4 represents the output of a multi-discipline working group representing members of various shipping trade organizations, mooring line manufacturers, shipyards, and OCIMF members.
What is MBL for ropes?
The minimum breaking load describes the maximum force under straight pull a free length of rope can be exposed to until it breaks. It is specified in daN or kN. The minimum breaking load for ropes required under EN 1891 A is 22 kN.
What is proper mooring procedure?
Arrange Mooring Lines Symmetrical: All mooring line must be arranged as symmetrical as possible with the breast line. The breast line should be perpendicular to the longitudinal centre line of the ship and the spring line should be parallel to the longitudinal centre line.
How do you calculate MBL?
The MBL, as a weighted score, is calculated according to the formula: (number of utterances MBL1 × 1 + number of utterances MBL2 × 2 + number of utterances MBL3&4 × 3)/number of all utterances (Pharr et al., 2000;Stoel-Gammon, 1989). …
What is minimum breaking strength?
The minimum break strength (MBS) is defined as the minimum single value from a series of five prototype rope assembly, including terminations, break tests.
What is meg4 certificate?
Issued by: TAC is issued by a class society and confirms that the product complies with the relevant TAC standards. It also confirms the rope characteristics: ISO ref. number (nominal diameter), linear density (weight per meter) and strength.
What are the OCIMF mooring equipment guidelines?
The OCIMF’s Mooring Equipment Guidelines (fourth edition 2018) should be the basis for your mooring policy. The document contains information and recommendations for all aspects mooring in your daily activities.
Is there any industry guidance on condition-based monitoring of mooring lines?
Further, there was no industry guidance on condition-based monitoring of mooring lines and tails. Since nearly all mooring injuries are a result of mooring line failures, OCIMF has strived to provide guidance and clarity on the condition-monitoring of mooring lines and there were several new terms introduced in MEG 4.
Why do you need a mooring rope manual?
This Mooring Rope Manual ensures you maintain business continuity. The main goal for managing mooring ropes according to MEG4 is the safety of your crew, but the guidelines offer more.
Who is responsible for mooring line maintenance and inspection?
The ship operator is responsible for the development and implementation of the ship’s LMP. The LMP contains the ship operator’s requirements for the management of mooring line maintenance, inspection and retirement during the operational phase of the mooring line lifecycle.
