Anchoring

Step 1Gangway & Security

Controls access (if permitted) through boat transfer and temporary gangway setups. Implements ISPS measures including ID checks, visitor logs, and restricted work zones. Weather and sea state determine safe boarding windows. Agent and pilot updates ensure readiness to heave anchor on short notice. The purpose is secure and safe ship access during lay-by. Success is defined by zero unauthorized boarding and no incidents.

Step 2Workers’ Assistance

Enables inspections and limited maintenance while waiting. Permits and risk assessments control allowable activities at anchor. Tasks are selected to avoid creating dependencies that could delay berthing. Records feed the ship’s maintenance system and port-call reports. The purpose is productive use of idle time without introducing new risks. Success is higher operational readiness once a berth is available.

Step 3Cargo Support

Prepares cargo gear, lashings, and documentation ahead of terminal operations. Verifies that stow plans and manifests match onboard status. Checks IMDG segregation and reefer readiness where relevant. Discrepancies are escalated early to planners or brokers. The purpose is a clean start for quay operations. The benefit is reduced first-crane delays and rework.

Step 4Cargo Survey

Conducts independent condition and quantity surveys as required by stakeholders. Surveys help prevent disputes and confirm readiness for sensitive cargoes. Results support insurance, charter party compliance, and terminal planning. Weather windows and launch availability determine timing at anchor. The purpose is objective evidence before cargo handling begins. The outcome is fewer claims and clearer accountability.
