Turnaround Operations: Managing Simultaneous Operations in Port

SIMOPS is a company method that may be integrated into the SMS: authority, interfaces and stop-work responsibility must be clear, while role titles, toolbox talks and ALARP depend on the adopted framework.

Operational Explanation

No dedicated IMO turnaround rule mandates a SIMOPS Leader, toolbox talk or ALARP criterion. These are possible company controls to use where prescribed by the SMS and Company risk-management framework.

Regulatory Reference

There is no single IMO regulation dedicated to passenger ship turnaround: the SIMOPS (Simultaneous Operations) discipline is a risk management framework, referenced by industry guidelines (including IMCA and ABS Group for the maritime/offshore sector) and integrated into the Safety Management System (SMS) required by the ISM Code for managing multiple, potentially conflicting activities in the same place and time.

Scope of Application

Turnaround and simultaneous activities managed under the SMS, port procedures and applicable law. The responsible person may be a designated coordinator or another person identified by the SMS; the title is not universal.

Procedure / How to Complete It

Map activities, interfaces and potential conflicts.
Assign authority, coordination and stop-work responsibility under the SMS.
Use toolbox talks, a SIMOPS matrix or dedicated coordinator where prescribed or selected by the Company.
Reduce risk to the level required by the company framework and law; use ALARP only when formally adopted.

Practical Example

Example: during the turnaround day, the designated Simultaneous Operations Leader identifies that the scheduled bunkering overlaps with the start of passenger embarkation operations on the same side of the ship, and reorganises the sequence of activities to eliminate the physical interference between the two operations before authorising them.

What Typically Goes Wrong

Analysis of AIS data on the vulnerability of scheduled turnarounds in cruise ports quantitatively confirms an operational intuition long known to crews: the compression of time available for subsequent activities, when a single turnaround operation is delayed, is one of the most concrete risk factors for on-time departure and, consequently, for the entire downstream itinerary.

Common Mistakes Mistake Library

Recurring errors are leaving interfaces unassigned or imposing names and controls absent from the SMS. Identify the responsible person, stop-work authority and the risk criterion actually applicable.

What the PSCO Checks

Turnaround itself is not typically subject to direct PSC verification, but SIMOPS risk management, if integrated into the Safety Management System, may be verified indirectly within the scope of ISM audits.

Operational Tips

Map potential interferences between turnaround activities before the day itself, not during operations.
Always designate a Simultaneous Operations Leader with clear authority, not a diffuse and implicit responsibility.
Communicate every delay along the turnaround chain immediately: the cascading effect on a compressed day is faster than it seems.

FAQ

Must a SIMOPS Leader always be appointed?

No. Responsibility and authority must be clear under the SMS; title and structure depend on the Company.

Is ALARP always mandatory?

No. Use it where adopted by the framework or required by applicable law.
