Hastings Pier in WW2, continued - Cryptic Camouflage

Eastbourne and Hastings Piers, and those at Brighton were subject to a mysterious project in late 1942.  The Royal Engineers based at Battle Abbey give us some information:

13th October: No.3 Section started work on job H.P. at Hastings Pier, where Major Woods, Captain Turner and Lieut. Love met Lieut. Evers at 08:30 hrs, who explained the job required, i.e., the screening off of the lower part of the pier. About 30% of the job was completed today.

The following day, job E.P. at Eastbourne Pier was begun, again, to screen the lower part of the pier.

Both jobs were to be completed by Saturday 17th October.  It is assumed that this entailed covering the piles and strutwork beneath the decking.

On 15th October, Hastings was 80% complete and Eastbourne 40%, but progress had been held up by a lack of cordage.  The 17th October deadline passed and it was another two days before the necessary cordage was delivered to the piers.

The work appears to have been completed around this time; nothing more is said of the matter until 7th November when the screens at both piers were lowered in tests.

Orders were received on 10th November that the screens must be lifted by the following night, which was duly done in the morning of the 11th.

The Divisional Engineer records "two sections rolling up the camouflage on Hastings and Eastbourne Piers.  The job is not the success it might have been."  The documents only give the above information. Was it some sort of unsuccessful trial at concealing something under the pier?  The screens were presumably at the shore end, where the cross-braces and risk of beaching would surely rule out landing craft being hidden there.
