The Dockmaster Pontoon is a state-of-the-art heavy duty pontoon system suitable for berthing large yachts, ferries and support vessels. Dockmaster has now become the pontoon of choice for the UK windfarm industry and has been installed in several harbours for personnel craft. Dockmaster can be supported on piled or anchored moorings.

Beckett Rankine has developed designs for the Dockmaster, working closely with the client and production teamto include refinements as required. Strength is provided by stressing the precast concrete side panels against the expanded polystyrene buoyancy block and all tied together with the concrete deck.

Riverside Quarter is part of the regeneration of the southern bank of the River Thames converting a brownfield site into new residential properties with modern riverside facilities with 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.

Beckett Rankine are involved in condition surveys of the river walls and have designed works to strengthen and enhance these traditional masonry structures. Environmental issues have been considered and mitigation measures include new barges for birds to nest and roost.

A small private dinghy harbour to provide shelter for two pleasure boats with direct access to Poole Harbour and the sea beyond. Although the protected area is only 17m x 10m it has created a pleasant environment and a useful addition to the back garden of one of the substantial residential properties along this coastline.

Beckett Rankine planned, designed and supervised the project. The marina walls were constructed using cantilevered sheet piles driven into the firm sandy bed. The seabed within the marina was dredged to a level that enables access by small craft at all but the very low tides.

Lydney Docks are situated on the upper reaches of the Bristol Channel and were originally constructed to facilitate cargo transfer to and from the region by barge. Having become disused and then fallen into disrepair following the transfer of cargo transport to the roads, the docks have been listed as a Scheduled Ancient Monument.

Beckett Rankine examined the docks together with the canal and prepared alternative schemes for regenerating the water area surrounding land. Our brief covered consideration of re-locating and enhancement of the flood defences and finding a new use for the harbour.

The Harbour at Watchet is on the southern side of the Bristol Channel in Western England. Breakwaters had been constructed on the gently sloping shoreline to provide a protected area of water at high tide. Exposed to severe storms from the west and with a tidal range of over 11m, there is no water in the harbour at low tide.

Beckett Rankine prepared a feasibility study for converting this harbour into a small boat haven with a focus on leisure craft with facilities for the fishing fleet. Central to the plan was construction of an inner harbour wall with a dock gate to provide permanently floating berths.

A new jetty was required to handle Liquefied Petroleum Gas (LPG) as part of the shore reception facilities needed to exploit the West Shetland offshore oil discoveries. Two new berths were needed for LPG carriers to load from a dedicated terminal at a protected location that had been identified on the Shetland Islands.

Beckett Rankine undertook a Front End Engineering Design (FEED) for the marine facilities. The design was for steel tubular piled dolphins to berth the vessels and a separate jetty head platform for loading arms and safety equipment and approach trestle for the pipework.

Commercial shipping trade at the port of Maryport has ceased with the exception of a small but active fishing fleet. Consideration is therefore being given to improve the surrounding area with the harbour providing a focal point to maintain the marine heritage. Alternative urban regeneration schemes have been assessed.

Beckett Rankine studied all the marine aspects of the project. This included a condition survey of the dock gates and recommendations for the design of a replacement system. An assessment to provide a forecast of future dredging and infrastructure maintenance costs was also provided.

With the improvement of much of Plymouth's waterside property over the last ten years, the City Council planned to provide a public transport link between strategic locations around this extensive harbour. These sites included Mounbatten and historic Royal William Yard. Plymouth City submitted a bid for a millennium grant.

Beckett Rankine prepared outline designs for the passenger ferry terminals at four new locations around the harbour. We also prepared a specification for the passenger ferry vessels for use on these routes. Costings were calculated for both the shore and waterbourne infrastructure.

A new steel floating breakwater structure has been installed to give all year shelter from waves at Falmouth Yacht Harbour. While protected from offshore storm waves, the marina is exposed to wind driven waves generated across the 3 km fetch within Falmouth Bay. Craft can now remain at their berths throughout the winter season.

Beckett Rankine advised the client on the procurement of the floating breakwater units and carried out a technical audit of the designs. Our work also included design of moorings using large stud linked chain and high performance anchors buried in the sea bed.

A new state-of-the-art lifeboat station has been constructed within the protected waters of the historic Ramsgate Royal Harbour. In keeping with RNLI policy an architecturally attractive building was needed. The building had to provide accommodation for crews and enable quick and easy access to both inshore and offshore lifeboats.

Beckett Rankine designed and supervised construction of the sub-structure, which was a reinforced concrete platform supported on steel tubular piles. Our work also included close liaison with the architects to provide all the engineering input to the building superstructure.
