Frankham were appointed by Livett’s to inspect their jetty at East India Quay and prepare a design for a guide rail system for a 30m pontoon to be moored on the front face of the jetty.

The ultimate objective of this project is to allow safe access to vessels at East India Quay by installing a new 30m x 10m pontoon and an access brow to assist the reactivation of the jetty. A point cloud survey by GPS Marine Ltd was utilised as part of the design works.

Frankham was responsible for producing fixing details for the jetty head and dolphin, and for the design of the pontoon guide rail systems. The design included detailed construction drawings and a design check certificate.

The calculation of the loads which will act on the newly installed pontoons comprised of wave, wind and drag forces. A combination of all three loads acting simultaneously were used as the most unfavourable scenario. Since the current loads are highly affected by the tide level, the current loads were considered at low, medium, and high-tide levels.

The project also included an initial site visit to obtain photographs, and the preparation of base drawings of the marine assets. The inspection works were conducted via foot and Livett’s own workboat, ensuring the comprehensive and efficient examination of the existing structure.
