The Future

ADS will continue to grow and continue to be the best diving and subsea support company in West Africa.

We have an aggressive purchasing plan for 2017/18 that will see us increase our IMCA diving spreads to six. Four of these will be “in class” to meet up with our clients stringent demands. Also this year saw the addition of a contaminated water diving container as well as hysdraulic tooling containers.

The success of the ADS NITROX diving programme to offer enhanced safety as well as cost efficiency for clients has culminated in the arrival of our dedicated NITROX container available and working in country

All diving operations carried out within ExxonMobil fields are now supplemented with observation ROVs to enhance saftey of the divers with the assistance from Marine Solutions.
