The crew of the work boat, Alison, were rescued after the vessel sank off Tower Pier on the River Thames as a result of a collision with a passenger vessel.

An investigation has been launched after the work boat, Alison sank after a collision with the passenger vessel off Tower Pier on the River Thames.

Both the Alison and the Typhoon Clipper were using the pier at the time of the accident on 5 December 2016.

The two people on board the work boat were uninjured as a result of the collision and were rescued by the Typhoon Clipper crew.

The Alison, which is owned by Crown River Cruises and is used by the company for inspection work, was recovered the following day by the Port of London Authority.

Typhoon Clipper is owned by the company MBNA Thames Clippers, which runs a fleet of river cruise boats.

According to the company’s website, Typhoon Clipper is one of a fleet of six 220-seater catamarans which it owns.

They can travel at up to 28 knots, are 38 metres in length and have an outside rear deck.

In October 2016, MBN Thames Clippers was named the Ferry Operator of the Year at the National Transport Awards.

It also recently announced it had placed the largest fast passenger ferry order for a UK shipyard in over 25 years.

Two new 170 capacity passenger boats will be built at the Wight Shipyard Co on the Isle of Wight, and will be in service by summer 2017.

In a statement, the Marine Accident Investigation Branch (MAIB) said it had “started an investigation into a collision between the passenger vessel Typhoon Clipper and the workboat Alison off Tower Pier, River Thames, London on 5 December 2016. The workboat sank and 2 people were recovered uninjured from the water.”
