Coastal Defenders

A mooring structure called a dolphin has brought the Isle of Wight ferries to a standstill. In desperate need of repair, the whole ferry terminal must move to allow the Coastal Defenders dive team to swing into action and repair the seaworn structure.

However, the team come across a mountain of discarded rubbish, ranging from teacups to prams, as they work day and night to get the job done on time.

The Coastal Defenders team face one of their smallest but fiercest challenges -mussels. These small but deadly shellfish have blocked the pipes of a huge vessel, stalling it in dock.

The divers must blast the mussels out of their hiding places to allow the ship to sail once more.

Work never stops for the Coastal Defenders diving team, and today they get a late call from a boat in peril. A missing lifeboat canister means the ship can't sail, causing chaos for the passengers that use the service for their daily commute.

It's a needle in a haystack hunt in near zero visibility, and local leisure cruisers create imminent danger for the diver under the water.

The Coastal Defenders dive team have been charged with clearing abandoned boats causing an eyesore and navigational hazard in a picturesque part of the river.

Facing the threat of dangerous chemicals, metal boats and lots of mud, the team must chase the tide in what is one of the most unusual daily commutes. But disaster strikes, leaving the team stranded into the night on one of their most challenging jobs yet.
