HEALTH & SAFETY
Manual mustering is used to evacuate an offshore installation during an emergency; knowing how many personnel need to be evacuated is crucial for operators
accounting for personnel. The T-Card system can be especially useful in remote areas where digital systems may have limited connectivity or when power is lost. Yet another point in its favour is
that the system is cost-effective. Unlike electronic systems, which demand highly priced hardware and software and require expensive maintenance and training, the T-Card system does not have high initial set-up costs or recurring maintenance expenses. The materials include T-shaped cards and a rack or a board, fairly inexpensive and seldom needing replacement or upgrading. Hence, this proves to be highly economically viable in smaller operations or installations with a shoestring budget. It is a highly flexible and adaptable
system. The system can be tailored to suit particular needs of an installation or operation. Colour-coding of cards, labelling with different information, and various configurations make the card suitable for a specific application in personnel tracking. This, again,

enables the adaptability of the system to work in conjunction with other safety and operation management systems, making it more functional in complicated environments.
DISADVANTAGES OF THE SYSTEM Though providing certain advantages, the system also entails a few possible disadvantages. The main problem is that the method tends to depend too much on manual entry and human intervention. It would require people to remember card movements and report status changes accurately for the whole system to work. Working in such a busy, high- pressure environment as an offshore installation, personnel may forget to update their cards or, worse still, deliberately manipulate the system to suit their convenience. This immediate dependence upon human behaviour introduces the possibilities of mistakes, omissions, and inaccuracies that can so easily defeat the overall system’s effectiveness.
