OCIMF MEG4 Mooring Gap Analysis & Engineering Assessment

A MEG4 mooring system gap analysis is an engineering review of a vessel's complete mooring arrangement, including lines, tails, winches and fittings, against OCIMF MEG4, SOLAS and Class requirements. Synergetic Shipping Technologies verifies the design values, grades each gap by risk, proposes a corrective path and, where needed, drafts vessel-specific Mooring System and Line Management Plans.

A gap analysis compares the whole mooring system, its documents and practices with MEG4 and identifies what falls short. An engineering assessment goes into the numbers: it establishes or verifies the Ship Design MBL and checks line design break force, tails, winch brake holding capacity and fitting SWL against it. Many operators take both together.

MEG4 is OCIMF's Mooring Equipment Guidelines, 4th edition, and is guidance rather than regulation. SIRE 2.0 and oil major vetting apply it to tankers, and RightShip carries the same principles into dry bulk. In practice, any vessel facing vetting or terminal scrutiny benefits from being assessed against MEG4 thinking.

Visual inspection cannot show how much strength a used rope has lost. Residual strength testing measures it, so the operator can decide with evidence whether similar lines in service should be retained or retired. It helps avoid discarding serviceable ropes early and keeping weakened ropes in service too long, and it supports line retirement criteria in the Line Management Plan. Synergetic Shipping Technologies arranges testing at OCIMF MEG4-accredited laboratories worldwide and provides the test certificate with photographic and video evidence.

We gather the facts of the event, the line's history and certificates, the mooring arrangement and equipment condition, and how the operation was carried out. From these we establish why the line parted, separate immediate causes from underlying ones, and recommend corrective actions on equipment, ropes, procedures and training so the same failure does not recur across the fleet.

Yes. When an oil major raises a query on a vessel's mooring system, mooring lines or mooring fittings, we review the design data, certificates and records, and prepare a clear technical response with supporting evidence for your office to submit. Where the query reveals a genuine gap, we recommend the corrective action needed to close it properly.

TMSA 3 Element 6A covers mooring operations. Our review looks at three areas: vessel design and mooring arrangement, the human element including crew practices and familiarity with the plans, and the mooring systems themselves. The result is a set of findings and improvement actions that give the office evidence of how mooring is managed and improved across the fleet.

No. Every mooring service stands alone. DigiMoor X7, the world's first Class and RightShip approved mooring software, is used on more than 1,600 vessels and is the option for operators who want ongoing compliance rather than a point-in-time report, with digital line registers, usage tracking and audit-ready records across the fleet.
