Berths, Quays & Jetties

Ships of all types need a secure structure to berth against. In deciding on the form of a berth, factors such as wave reflection and soil conditions have to be considered as well as just the cost to construct.

Berths offering a similar function may be in various forms at different ports around the world, because they have been built to suit the particular conditions and to make use of the materials that are readily available.

Steel and concrete are commonly used, either for open piled jetty or dolphin structures as well as solid quay walls. High quality workmanship is essential to avoid early deterioration.

Fenders protect the structures and have to be designed to suit the vessels, often using a combination of rubber, steel and timber.

Meghavaram Port Masterplan

A new coal fired power plant is planned in northern Andhra Pradesh with blended fuel coming both from overseas as well as coastal India. The selected site is remote from all developed ports, so a captive jetty is required for panamax coal carriers. The jetty will also support the cooling water pipes with intake and outfall structures.

Beckett Rankine prepared a detailed project report (DPR) for the new jetty. Site surveys were carried out to identify the seabed levels and ground conditions where the jetty is to be constructed. Mathematical model studies were also carried out to identify likely wave heights, current and othermarine parameters.

Onne Cement Terminal, Nigeria

A new bulk cement terminal at Onne, near Port Harcourt. The project involved dredging to deepen the access channel and use of the dredged spoil for land reclamation. There was also construction of an access road over the swamp, construction of a jetty and berthing dolphins with shore side administration and support facilities.

Beckett Rankine have planned and designed marine and shoreside facilities for the cement terminal, including navigation chanels and road access. Working closely with a team of local engineers we have also supervised the dredging and construction works on site.

Rainham Wharf

The Thames-side barge wharf at Rainham had been constructed following the Second World War using some of the floating roadway units that had returned from the Mulberry Harbour. Facilities at the wharf needed to be modernised to accommodate large self-discharge dredgers. The imported gravel is much needed for construction.

Beckett Rankine inspected the marine facilities and designed strengthening to the existing dolphins. New dolphins were also designed to support a replacement pontoon and a new conveyor system. A check was carried out on the flood wall in the area of the new stockyard.

London Gateway (formerly Shellhaven)

The former Shell Oil terminal in the lower reaches of the Thames Estuary is to be redeveloped as a deep water port. Its close proximity to London and the motorway network makes this a good site for a substantial container terminal. P& O ports worked with Jacobs Shipping to include a roll-on, roll-off freight terminal.

Beckett Rankine prepared a masterplan for the roll-on, roll-off terminal as the first part of the development. This included outline design of ferry berths with pontoon and linkspan bridges to accommodate the six metre tidal range, together with shoreside facilities.

Krishnapatnam Port Masterplan, India

The State of Andhra Pradesh is developing more quickly than most other states in India. The existing minor port at Krishnapatnam is to be expanded to accommodate panamax coal carriers principally for delivery of coal for power generation. This is a BOT project. Large quantities of iron ore can also be exported from the hinterland.

Beckett Rankine is working as part of the sponsoring organisation and has been instrumental in preparing plans for a phased development of the port to match the anticipated cargo volumes and revenues. These plans have been passed by bankers as financeable.

Greenwich Promenade Pavilion

A new pavilion is planned at Greenwich on the riverside pier near to the historic sailing vessel "Cutty Sark" giving a landmark entrance building to Historic Greenwich. From its strategic position on the apex of the riverbend the glass and steel structure has been designed to give extensive panoramic views of London's docklands.

Beckett Rankine had the task of repairing and strengthening the foundations to the structure which comprises a 100 year old masonry quay structure. The majority of this substructure is below the high tide level and requires careful attention to detail to maintain its structural integrity.

Hainan Hohbond Oil Refinery, China

A new refinery is to be constructed and a new harbour is needed for oil tankers serving the refinery. This includes berths for vessels ranging in size from 500 dwt to 60,000 dwt within the protection of a new breakwater. Also a single point mooring for crude carriers up to 350,000 dwt. Provision of a new dredged channel and navigation aids.

Beckett Rankine reviewed previous designs prepared by UK and Chinese companies and restructured the harbour layout to meet new operational requirements. Focus was on cutting costs and satisfying local and international standards. This included a FEED of the marine facilities.

Heysham Ferry Port

This busy port now has three ro-ro berths to accomodate ferries working the thriving Irish Sea routes. Much of the old infrastructure has been modified to cater for the requirements of new vessels. As a commercial port, it has been essential to adopt economical and efficient engineering solutions for all refurbishment projects.

Beckett Rankine have worked on projects to upgrade several berths. Most recently we designed and supervised installation of the high performance fendering system at the timber staging on No.1 berth. Conventional ferries and high speed SeaCats can now be accomodated.

Braye Harbour, Commercial Quay

The Commercial Quay at Alderney required an upgrade due to its decaying fabric and the need to facilitate access for larger vessels. The relative merits of reconstructing and enlarging the commercial Quay were considered and various site investigations undertaken to determine the ultimate scheme.

Beckett Rankine prepared a masterplan for development of the harbour and plans for refurbishing the quay, including cargo and passenger handling issues. Hydrographic and geotechnical investigations were undertaken and hydraulic modelling to assess wave climate in the harbour.

Ro-Ro Ferry Ports in the Gulf of Cambay, India

The Gujarat Government has decided to develop a network of ferry services around the Gulf of Cambay with the objective of helping to draw together the people around this vast gulf. Both passenger and Ro-Ro ferry terminals were needed at four locations. Three of these are at entirely new port sites and two at developing harbours.

Beckett Rankine co-ordinated the project with design of berths, breakwaters, linkspans and dredging together with shore terminal facilities for freight and passengers. We have also provided an assessment of possible ferry routes, economic analysis and advice on operator selection.
