Doran Consulting is currently engaged in the role of Lead Designer for the Marine Package of the Nationally Significant Infrastructure Project (NSIP), Tilbury 2, with an estimated project value of £106M. Doran Consulting initially undertook extensive mooring and berthing analysis at each of the 3No. berths for a variety of RO-RO, CON-RO, Car Carrier and Bulk Carrier vessels (up to 250m LOA and 115,000t displacement). Following this, Doran Consulting designed 15No. multi-pile berthing and mooring dolphins, 22 No. access walkways, including 30m span articulated walkway, pontoon restraint piles and a bankseat structure. Doran Consulting also carried out dredge pocket modelling for the 3No. berths to determine dredge quantities and underkeel clearance, dredge pocket slope stability analysis; and the design of a 330m long underwater dredge pocket sheet pile cut-off wall.
In addition, Doran Consulting is providing design services for the Terrestrial Package, including site wide watermain design.
The recent launch of the 65m long linkspan and 55m x 45m floating pontoon from a slipway in Ravestein BV yard in Deest, Holland, marks a significant milestone in this project. The pontoon will provide loading/unloading facilities for two berths, and link to the new terminal, for an upstream and downstream berth accommodating RO-RO, CON-RO and Car Carrier vessels. The Doran Consulting designed bankseat and 2.4m dia. pontoon restraint piles will support these structures and are currently under construction.
