14 The Authority also actively promotes a forum for its pilots, the Pilots’ Operational Advisory Panel (POAPs), where pilots’ representatives and management meet to discuss issues with a view to improving common goals. Additionally, a hazard review panel, comprising managers and pilots, meets on a two monthly basis where they frequently discuss issues taken forward by Navigation Advisory Panels, which may be formed following incidents on the river. PLA owns, in conjunction with HR Wallingford 1 , a sophisticated two dimensional tidal model, which gives detailed tidal predictions at various points on the River Thames; the predictions for Coryton at the time of the accident are shown in Figure 6. Observed tidal values and surge differences from the predicted datum are monitored at various points throughout the river; Figure 7 gives this information for Coryton, 2 hours before and after the incident. This indicates that the heights of tide, and therefore stream velocity at the time of the accident, to be very close to the predicted values. 1.7.1 Pilotage The London Pilotage District stretches from Putney Bridge in the west to the Sunk pilot station in the east. At the time of the accident the PLA employed 90 pilots of varying proficiency and ability, including: • Twelve berthing pilots – specialist senior sea pilots retained for their experience of safely berthing and unberthing tankers of > 11,000GT or 160m in length. • Sixty six sea pilots, ranging from class 4 to class 1 pilots, responsible for navigating vessels safely from the outer pilot stations to inland as far as Crayfordness. • Twelve river pilots who specialise in the stretch of the river between Gravesend and London Bridge, three of whom are bridge pilots specialising in under bridge clearance from London Bridge to Putney Bridge. Compulsory pilotage is required for, among others: all specified vessels (vessels carrying explosives, flammables etc); vessels > 50m carrying marine pollutant in bulk, and vessels with an operating draught of 5m or more. PLA pilots work a 9 days “on”, 6 days “off” rota, with pilots moving to the bottom of the “turns list” after completing a “trip” or act of pilotage. This normally allowed no fewer than 8 hours off duty after an 8 hour “trip”, or 12 hours off after a 12 hour “trip” etc. The system allowed the Authority to service an average of 26 sea pilotage acts and 5 river acts daily. After being notified of a pending “trip,” pilots had the option of either attending the pilots’ “ready room”, at PLA offices, to make preparations for their trip or, where a pilot had external internet access to POLARIS (the Port’s Ship Information System), they could join a ship directly from home. A fundamental part of a pilot’s preparation for a “trip” is the compiling of a Passage Plan. PLA had a house style Master/Pilot Information Exchange and Passage Plan (Annex 4), but did not insist on its use by their pilots; this plan had a section dedicated to manoeuvring and mooring. PLA allowed pilots to 1 HR Wallingford: Independent research and consultancy experts in civil engineering and environmental hydraulics; formerly the Hydraulics Research Station of the UK Government.
