Battersea Reach Waterfront

Battersea Reach Waterfront

The Battersea Reach site, found on the south bank of the River Thames in Central London, is being developed into a major residential area. However, the planning, environmental, and river authorities required that an aesthetically pleasing answer to the problems of animal habitats on the busy river should be found.

Newhaven Dredging

Newhaven Dredging

Dredging at Newhaven twice a year in order to maintain adequate depth of water in the entrance channel for the port and at the berths. A trailing suction dredger is used to dredge about 250,000T per annum. The spoil, which is a combination of sand and silt, is deposited at an approved offshore dumping ground.

Beckett Rankine prepared and tendered the contract for the biannual maintenance dredging. Our work now includes administration of the contract and supervision of the dredging work and surveys. Formal returns are made to the authorities for quantities of material dumped at sea.

Newhaven – Quay Repairs

Newhaven – Quay Repairs

Newhaven has many quay structures that have recently required repairs. Over the years these have evolved as composite structures because of the strengthening needed to give greater water depth at the berths. For example, East Quay is a concrete gravity wall founded on timber piles with steel piles to support the crane piles.

Beckett Rankine have designed and supervised several quay repair projects at Newhaven. These have included installation of ground anchors to support the West Quay sheet pile wall, design of a steel pile underpinning system for East Quay and new fendering for ship berths.

Cutty Sark Preservation

Cutty Sark Preservation

The Cutty Sark was designed to bring tea over from China. She was launched in 869 with a design life of 30 years, and as a result, she was showing serious signs of corrosion in the composite iron frame and timber plank hull. Action had to be taken so that the famous landmark did not disintegrate with the power of the river water.

The Cutty Sark was designed to bring tea over from China.

Action had to be taken so that the famous landmark did not disintegrate with the power of the river water.

Beckett Rankine proposed several techniques to preserve the Cutty Sark. These include electrolysis, replacement of damaged parts, and mechanical cleaning. The works are essential so that this major tourist attraction can survive for a further 50 years without any need for more repair.

As the electrolysis could damage the timber planking, the planks had to be removed when this process is carried out. The ship, weighing in excess of 1,000 tons, was lifted and supported by a framework that does not cause any damage to the structure, so an exhibition can be created underneath.

Greenwich Pier Refurbishment

Greenwich Pier Refurbishment

Greenwich Pier is one of the most heavily used passenger piers on the River Thames. It provides a gateway to tourist areas in South-East London, including the historic vessel Cutty Sark and the Royal Naval College. After many years of service, the floating structure needed refurbishment, with the replacement of some of the key elements.

Queens Jetty Reconstruction

Queens Jetty Reconstruction

The main lay-by jetty at the Falmouth Shipyard was formerly a timber structure and was severely damaged by fire. A repair contract was awarded quickly with the requirement to rebuild the jetty in a short timeframe. The design and construction contract used pre-fabricated elements and was completed in 9 months.

Millbank Millennium Pier

Millbank Millennium Pier broke new ground in passenger pier design. The pier links Tate Britain, Tate Modern and Saatchi gallery by riverboat. The aesthetic appearance of the pier was a critical requirement in the design. The end result was a functional floating sculpture formed of faceted steel plates.

Peruvian Wharf Survey

Peruvian Wharf Survey

Peruvian Wharf is located on the River Thames in the London Docklands region, close to the Thames Barrier and London City Airport. After a long history as a commercial cargo wharf, the site was cleared to make way for plans to redevelop the land. However, it remained a safeguarded river wharf site.

Wandsworth Riverside Quarter

Riverside Quarter is part of the regeneration of the southern bank of the River Thames, where a brownfield site has been converted into new residential properties with modern riverside facilities, including boathouses and a riverbus service. The old river walls restrain the tidal river flow and also form part of the flood defences along the River Thames.
