ASOG, CAM & TAM

Operational activity planning applies to all sectors of offshore marine operations, including offshore drilling, project & construction vessels and offshore supply vessels – especially to dynamically positioned (DP) vessels.

DP & Marine Assurance Norway AS provide Critical Activity Mode (CAMO), Task Appropriate Mode (TAM) and Activity Specific Operating Guidelines (ASOG).

In accordance with IMCA recommendations, the guidance is presented to the Dynamic Positioning Operator (DPO) as a quick reference tabular format. These abbreviated documents provide a cross reference to the DPO and other relevant engineering and bridge personnel.

Critical Activity Mode (CAMO)

The Critical Activity Mode of Operation (CAMO) shows how to configure the vessel’s DP system, including power generation & distribution, propulsion and position reference systems.

Task Appropriate Mode (TAM)

Task Appropriate Mode is the configuration that the vessel’s DP system may be set up and operated in, accepting that a single failure could result in exceeding the worst case failure and could result in blackout or loss of position.

Activity Specific Operating Guidelines (ASOG)

Activity Specific Operating Guidelines (ASOG) are generally presented in tabulated format and set out the operational, environmental and equipment performance limits necessary for safe DP operations while carrying out a specific activity.
