If help has not arrived in 10-12 hours after having abandoned an OSV in a survival craft, you should do what?

When you have abandoned an Offshore Support Vessel (OSV) and have been in the survival craft for 10-12 hours without any sign of rescue, it is crucial to conserve resources and maintain stability in the survival craft. Shutting down the engines and deploying a sea anchor is an effective strategy in this scenario.

The primary purpose of shutting down the engines is to avoid unnecessary fuel consumption and noise, which may also cause distress to the occupants of the craft. Keeping the craft steady is essential for safety and comfort. Deploying a sea anchor helps keep the survival craft oriented into the prevailing seas and reduces drift. This is particularly important in ensuring that the craft remains more stable and maintains its position, making it easier for search and rescue teams to locate it.

Maintaining a position and minimizing movement also helps preserve the energy of the individuals on board. The sea anchor can further assist with the craft's ability to ride out any adverse conditions, thereby increasing the likelihood of remaining safe while waiting for assistance to arrive.

In contrast, activating a distress signal, starting the engines, or setting up a communication device could lead to complications or unnecessary risks. They may not be as effective or safe compared to the stability offered by shutting down the engines and letting the sea
